Tropical Island
When the travel budget looks thin there’s an alternative to make it anyway, at least if
you’re in the vicinity of Berlin. The new “travel destination” Tropical Island located in
the world’s largest self-supporting structure presents you with the waters of the Seven
Seas and the Bali Lagoon, no less than seven restaurants, a tropical rain forrest and a
water temperature of 32°C. And beaches of course. Read more on pages 16-17.

From no product to key product
Ten years ago, the building system (prefabricated steel buildings) was just a small fraction of
Lindab sales. Today, it accounts for one-fifth of
sales in the Profile business area. And no one is
predicting a reduction in that number. The explanation for this development is twofold. As always,
it is the needs of the market that drive demand
and development. These types of cost-efficient,
quickly established buildings are gaining a lot of
ground. In addition, as a component manufacturer in the construction industry, Lindab was well
suited to design complete package solutions and
develop the area Building Systems. When we
established ourselves in Central and Eastern
Europe, we quickly realised that there was a great
need for building systems as a product, but with
completely different requirements than those of
the simpler steel halls we delivered previously.
After the acquisition of Butler Europe in
2002 – with a great number of years behind us
as exclusive supplier of lightweight girders to
Butler – Lindab took a definitive step up into a
higher division. We are now a leading supplier
within the segment industrial and commercial
steel buildings. The total European market for
this segment is expected to reach approximately
SEK 40 billion. We and other suppliers of prefabricated steel building systems currently account
for approx. 5% of this market – a share that is
continually growing.
Surveys have shown that product quality,
short construction times, flexibility, lower total
cost, short capital tie-up through quicker access
and cost efficient design possibilities are the
benefits that customers associate with steel
building systems. Added to this is the importance of a strong, well known brand.
Lindab’s product area Building Systems is
currently one of our key products, providing
these benefits to builders and property owners
throughout Europe. Our strong growth in the
area also continually increases our ability to further improve on how we satisfy these demands.
This is always our main driving force – being
able to provide our customers market leading
solutions. We shall continue along this path of
success.
Profile
Peter Andsberg,
Business Area Manager Profile
Even better solutions to many more
Solutions that are really adapted to customer needs are essential to Lindab and business area Ventilation. Lindab has a business
structure and work method that creates rather
good conditions for delivering customer-oriented
solutions that are really in demand in the market.
Listening to what the customers want and maintaining a running dialogue on what we can
change and improve generates success for both
our customers and us at Lindab. This is something we give the highest priority.
If we can give more companies in more
countries access to the solutions we offer in our
product areas Air Duct Systems, Comfort (technical air products) and Machinery (equipment for
the manufacture of circular ducts and components), we can spread our ideas on simplified
construction to a broader clientele.
These three product areas are a visible
embodiment of our new organisation, in place
since the beginning of 2005. It places a clearer,
more natural focus on our core product – circular duct systems – and aims to improve our target-group focused service and support within
these three product areas.
In the Central and Eastern European markets, we shall clearly intensify our efforts, with a
more goal-oriented presence in these growing
markets. By using the experiences and infrastructure established by business area Profile,
we shall reach new customers and spread the
benefits of circular duct systems to more markets.
Parallel with such, the work of encouraging
the traditional ventilation markets towards
increased utilisation of circular duct systems
continues. Better and simpler solutions for all of
our customers, delivered with neatness and
order through a close and reliable relationship is
something we believe strongly in.
Hannu Paitula,
Business Area Manager Ventilation
Ventilation
New business area manager for Ventilation
On 1 January, 2005 Hannu Paitula
was appointed new manager of the Ventilation
business area. Hannu Paitula has been active in
the ventilation industry since 1985, gaining vast
experience. “I’ve spent most of this time working
for Fläkt, ABB and then FläktWoods”, explains
Hannu
Paitula, left his position as CEO of
FläktWoods Group in 2003 to run his own management consulting company. There is no
resisting the call of the ventilation industry, so
when Lindab was searching for a new business
area manager in autumn 2004, Hannu Paitula
was high on the list of possible candidates.
“It was a bit surprising to receive this offer
so soon after deciding to run my own business,” continues Hannu Paitula. “The offer,
however, was hard to refuse. So, after contacts
and meetings with the Lindab group manage-
4
ment, the matter was settled in practically no
time.”
With quick decisions and straight answers,
Lindab played Hannu Paitula’s song. “Neatness
and order and down to earth are two of
Lindab’s core values. They were able to bring
this to life directly,” he continues. “Keeping
things clear and simple is an extremely important part of successful business. That’s why it’s
important to always look at the whole picture
before going down to the detail level.” Hannu
Paitula was impressed by the entrepreneurial
spirit and enthusiasm that Lindab greeted him
with. “Here, everyone has a great desire for
activity. It is now my role to make sure that we
are all striving toward common goals at a good
pace.”
Hannu Paitula, new business area manager for Ventilation, has a
vast international background, which will be quite useful for our
continued geographic expansion in the business area.

Lindab’s new target group focused website concept
Many websites in one
Customer-oriented solutions are
something every serious-minded company must
have high on its list of priorities. A natural part of
this are unified, up-to-date and well functioning
websites.
Sitebuilder is a tool used
in a collaborative project
between Lindab Denmark and
Lindab Sweden in order to
create even better national
websites. “A good website
must be adapted to the individual needs of the customers
and users but at the same
time be easy to update and
supplement,” says Torben
Philippsen, head of Lindab Denmark’s web
development.” “Sitebuilder’s CMS system
(Content Management System) has enabled us
to create a website concept that is directly
aimed at Lindab’s various target groups and
provides individual routes to the sought-after
information. An architect and an installer have
quite different information needs. Now, they can
select “their” path directly from the start page
and go right to the areas of interest to them.”
Lindab Denmark has just launched their
new website www.lindab.dk.
Now the private individual,
sheet metal worker or architect can choose their path
directly. “We think our users
will appreciate this target
group adaptation. This combines ‘several’ websites into
one,” says Torben Philippsen.
“The saying goes that it’s not
about gathering information,
its about getting rid of the unnecessary information. That’s just what our new
website does.”
March saw the launch of Lindab Hungary’s
new website completely based on this concept.
Next in line is Lindab Sweden followed by several other countries.
Light exhibition concept
Lindab’s large exhibition concept
is now in its 3rd year and has been put to great
use. It has been seen at the ISH trade fair in Germany, Padova and Mostra Convegno in Italy,
Hilsa in Switzerland, Nordbygg in Sweden, Interbuild in England, VVS-dagene in Norway and
Finnbuild in Finland. The concept was most
recently used in the spring at ISH 2005 in Germany.
“It works well, lives up to our graphic profile and gives great opportunities to show our
products installed and running,” says Lars
Dahlström, communications manager at
Lindab. But, if you need small, simple displays it does not really work well. Then both
transports and display assembly become
costly since the display constructor of the
individual trade fair must carry out the work.
That’s why there is a new, supplemental
exhibition concept named “light” for smaller
areas up to approx. 50 m2. “Light” comprises a
carpet, information desk, table and chairs,
brochure display, lighting and individual frames
with support columns that form airy “walls”
though graphics mounted in each frame via
magnets. “It gives an impression that falls in line
with the large concept,” says Mårten Edorsson,
project manager at Molins, which was responsible for designing the concept. “The biggest
advantage is that now Lindab’s own personnel
can quickly and easily carry out assembly
based on simple instructions. And no trade fair
visitor will miss that it is Lindab – the company
that “has the solution” – that is on display.
Good results
for Lindab
Operating profit for the year was in
absolute terms the best ever for Lindab with an
EBITA of SEK 374 million (305). “During the year,
we gradually improved profitability, with better
earnings in each individual quarter compared to
the previous year,” says Nils-Johan Andersson,
CFO of Lindab. Adjusted for exchange rate differences and acquisitions, organic growth was
6.5 percent and amounted to SEK 5,477 million
(5,302), insignificantly below the group’s long-
term target. “A major part of the improvement in
financial results for the year can be attributed to
strong margins as a result of focused pricing
efforts,” continues Nils-Johan Andersson. “As a
result, the group is in a strong financial position
with an equity/assets ratio of 45 percent and
stable cash flow.”
General market development is weaker than
anticipated. Nonetheless, the Scandinavia operations were able to maintain their market positions. The markets in Central and Eastern Europe
developed strongly for the Profile business area,
giving Lindab a stable platform and strong
market position in this region. Sales of core products Rainline and Building Systems have
increased and contributed to the improved
result.
Lindab’s new European production facility in
Prague was put into operation last year. This
investment was done on budget and on time,
reached productivity goals and created good
capacity for increased growth. Positioning itself
closer to the markets of growth has given
Lindab new business opportunities and
increased its competitiveness.
Lindab’s new exhibition concept “Light” has been successfully used in the spring at trade
fairs in both Romania and
Hungary.

Premiere for
Copenhagen’s new
opera house
When someone says “opera” one’s thoughts quickly turn to artistic and vocal expression, perhaps in Italian or
German. But opera is also an extremely complicated undertaking in which lots of activities must go on without disrupting one another. This is also the case for Copenhagen’s new opera house, where over 1,000 rooms clearly speak
the language of great activity. The most important of these rooms is the Main Stage in which a full house in the spring
will enjoy Aïda – and the air supply streaming from the diffusers supplied by Lindab.
O
nce again Denmark and Copenhagen, added another architectural
landmark to the already long list of
beautiful, spectacular and typically Danish
buildings. Of course, it is not the regard for the
building that is of utmost importance. It is what
is behind the arched glass facade, which bends
out toward the harbour entrance. Copenhagen
has now gotten its new opera house, the roots of
which extend back to the middle of the 13th
century and King Christian II’s Royal Trumpet
Ensemble, predecessor to the Royal Danish
Theatre’s orchestra.
new national stage was inaugurated through a
Royal Command Performance on 15 January
and its first spring season opened with Verdi’s
Aïda on 26 January.
The opera house, which covers 41,000 m2
and has over 1,000 rooms and 14 stories (5 of
which are subterranean), has received a lot of
attention. Designed by Danish architect
Henning Larsen, it comprises two stages: the
Main Stage and Takkelloftet, the experimental
stage. The Main Stage seats an audience of up to
1,703, has an orchestra pit for 110 musicians and
has so many possibilities as regards technology
albeit with very, very artistic characteristics. Thus
a project of this type is based on very unique
solutions that are of a totally differing nature.
The architectural ambitions were extremely
high. In turn, this placed great demands on all
technical solutions – from facade facing to the
air supply system in the main auditorium.
The opera house was built on old mud
masses, which required that the entire building
be built in a waterproof retainer extending 14
meters below ground. “It cost millions just to
reach ground level,” explains Jørn Treldal, “and
among all the other rather exceptional technical
requirements, the sound requirements for the
main auditorium were anything but simple.”
British Arup Acoustics, who handled all acoustic
issues, set the acoustic standard to an exacting
PNC 15. “This is an acoustic standard that places
great demands on soundproofing, especially for
low frequencies. This acoustic level is so low that
it cannot be heard by the human ear. Even
measurement can be difficult.”
Extreme acoustic standards
The new opera house, located on the island of
Holmen opposite The Little Mermaid, will not
be a replacement for the old on Kungens
Nytorv. It will instead give the Royal Danish
Theatre two stages to host the repertoire of
opera and ballet that has been its trademark
since the end of the 1800s.
Modern possibilities
On 1 October 2004, shipowner Mærsk McKinney Møller, on behalf of the A.P. Møller and
Chastine Mc-Kinney Møller Foundation, turned
over Copenhagen’s new opera house to Prime
Minister Anders Fogh Rasmussen, the Danish
people and, above all, the Royal Theatre. The
6
and space that it is without a doubt one of the
world’s most modern opera houses.
Extremely complicated
project
Nordic consultant Rambøll together with
Henning Larsen’s architecture firm was responsible for project planning for the opera house as
well as for advising on the project’s intricate
technical installations. Engineer Jørn Treldal of
Rambøll was responsible for all HVAC installations. “The opera house has probably been the
most complicated project I’ve been involved in,”
he says. “You have to think of an opera house as
a machine, where activities are almost industrial,
* The Royal Danish Opera Photo: Martin Mydtskov Rønne
These rather extreme acoustic standards put the
pressure on not just Rambøll but also the suppliers of the sound generating equipment. “Since
the diffusers themselves always generate noise,
this was one of the products that was critical
from an acoustic standpoint,” explains Jørn
Treldal. “Not only did we have to fulfil PNC 15,
but we had to combine this with the architect’s
specific vision of the design and appearance of
the diffusers themselves.” All of the diffusers in
the main auditorium are supplied air from the
large pressure chamber beneath the seats. This
pressure chamber is connected to the fan unit
via a duct system and soundproofing.
The diffusers in the balconies of the new
opera house are all specially tailored to the
curvature of the low wall behind each seat.

good that everything went so well from the fullscale test and adaptations to completed delivery.
The expectations of both me and my colleagues
were completely fulfilled,” concludes Jørn
Treldal.
Complicated installation
Full-scale test in Farum
In order to measure and develop a ventilation solution for
Copenhagen’s new opera house, Lindab, under the leadership
of laboratory manager Jørgen Schmidt Madsen, built two
complete, full-scale models of both the stalls and the balcony
with a total of 24 diffusers. “This gave us full opportunity to
measure and document air flows, acoustic pressure and
power requirement in a manner that was both efficient and true
to reality,” says Jørgen Schmidt Madsen. “It was also the key
to being awarded this important order and at the same time an
important tool in the developmental meetings the followed.”
Total solution
“From an early stage we suggested to the proprietor that it was time to start selecting and sizing the ventilation fittings,” continues Jørn
Treldal. “The floor of the main auditorium itself
has a very involved geometry since a clear view
from any seat must be guaranteed. That means
that selection of diffuser came into play at the
stage when the aesthetics, safety, climate comfort
and construction techniques were being woven
together into a total solution.”
Positioning the supply air beneath the seat is
now a common practice in auditoriums of this
type. The diffuser can be positioned in the seat
body, in the floor beneath the seat or in the
raised area that is sometimes found behind the
seat. “For practical reasons, it is options two and
three that are most often utilised and that is the
case here,” says Jørn Treldal. “When we got this
far, we were sure that a standard fitting could
not satisfactorily meet the challenges posed by
the acoustics, construction techniques or aesthetics. That’s why at this stage we invited two
leading suppliers, including Lindab, to propose
supply air solutions for the main auditorium.”
Clear margin
Lindab quickly decided to build two full-scale
models of the opera house’s stalls and balcony
installations in its laboratory in Farum. “This
allowed us to perform all necessary and comprehensive measurements and adaptations as well
as in the next stage present a functioning fullscale solution with verified measurement values
to the proprietor, consultants and architect,”
explains Frank Just Larsen, sales engineer and
Lindab project manager for the opera house.
“After presenting the solution designed in
Farum, Lindab was selected by a clear margin to
be the supplier of the opera house’s diffusers,”
says Jørn Treldal. “We had the technically best
solution. The physical proximity of Lindab in
Farum was not a disadvantage either.”
A deciding factor for this type of purchasing
is the accuracy of the measurements presented
by the supplier. “I am quite pleased with the collaboration with Lindab representatives, such as
laboratory manager Jørgen Schmidt Madsen,”
says Merethe Alder of Henning Larsens
Tegnestue, responsible for parts of the main
auditorium. “Lindab’s preparation with fullscale tests showed that it was possible to achieve
the set acoustic standards. The design of the grill
was also of great importance since these devices
are so clearly exposed.”
Through the acoustic measurements taken
by Arup Acoustics upon completion, one could
happily establish that acoustic standard PNC 15
could be achieved.
Installation of the diffusers, duct system and
other ventilation components was carried out by
ventilation contractor E. Klink, which has been
a customer of Lindab for many years. “We manufacture both circular and rectangular ducts, but
always buy pressed duct components from
Lindab,” explains engineer Kjeld Christensen of
E. Klink. “Lindab has a broad range and offers
quick deliveries. Not to mention that one of
their branches is literally around the corner.”
For E. Klink, the opera house was a very
interesting yet very large prospect. “Installation
has taken about 2 years and was special in that
project planning and installation were done in
parallel on the construction site by both
Henning Larsens Tegnestue and Rambøll.
Changes and adjustments were an everyday
occurrence during those 2 years,” continues
Kjeld Christensen. “The most special was, however, the acoustic standards since some rooms,
like the main auditorium, were to have an
extremely low acoustic level. Acoustic standard
PCN 15 is something we have never worked
with before.” All Lindab diffusers were marked
since they were adapted to the curvature of the
auditorium. Lindab also supplied diffusers to the
foyer and the rehearsal hall of the chorus.
“Construction of a new opera house in Oslo will
soon be underway,” concludes Frank Just
Larsen. “We have thrown our hat into the ring
and submitted a tender. Delivery to the
Copenhagen Opera House has helped us finetune our solutions and measurement methods
for large, extensive concert and opera houses.”
Good collaboration
The 1,700 diffusers delivered to the opera
house’s main auditorium are designed according
to the displacement principle and consist of a
box with perforated rear and a powder-painted
black grill with a radius adapted to the curvature of the auditorium.
“I think we have had a very good, close collaboration with Lindab. Since Rambøll suggested Lindab as a possible supplier, it feels extra

Linné
Highly topical
Kunskapsprojekt
R
2007 marks 300 years since the birth Carl von Linné. That’s not the only reason
that Sweden’s most famous scientist remains topical. He is still of interest
because the Linné system of classification, which he presented in Systema
Naturæ, is still used the world over. Soon Linné, the neglected Swedish icon,
shall be brought further into the limelight.
W
hen medicinæ doctoris Carl
von Linné published his
Systema Naturæ in 1735, he
generated world renown not only for himself,
but also for the Kingdom of Sweden. In his treatise, Linné presented what would become the
standard system for classifying both plants and
animals in nature. By using two Latin names for
each animal and plant type, he created in
Systema Naturæ the naming system that is still
in use by today’s botanists, ornithologists, culti-
vators and scientists. Born in Råshult in Småland, Sweden in 1707 and died in Uppsala in
1778, the 300th anniversary of his birth is
approaching. This is just one of the reasons that
“Intellectual Project Linné” saw the light of day
in 1999 as a result of a collaboration in the socalled Linné district between Stenbrohult and
the municipality of Älmhult. “The goal is to
increase knowledge of Carl von Linné and his
life’s work,” explains Lars Nexe, project manager of Intellectual Project Linné.
Cultural tourism
“What we are creating in Linné’s native district
is a centre to spread knowledge of his accomplishments, his great abilities in biology, mineralogy and zoology and, of course, about Carl von
Linné himself,” continues Lars Nexe. The core of
the project is the experience facility with
Orangery, Visitor Centre and Botanical Garden
which is being constructed in Möckelsnäs, a
stone’s throw from Linné’s birthplace in Råshult
and near Stenbrohult and the church for which
his father was
vicar. “The goal is
to not only make
the Linnédistrict a
hub for genuine
cultural tourism
involving Linné,
but to also use education/research aimed especially at children and youth to increase knowledge of the nature all around us.” There is also
an ambitious web portal at www.linnaeus.nu
which provides access to many facts on Linné.
Approximately 2,200 pages are available for
knowledge-thirsty friends of Linné.
Orangery
blessing of both the National Property Board of
Sweden and the National Heritage Board,” explains Lars Nexe. It was originally constructed in
the middle of the 1700s, but when Linné’s son
took over operation after his father’s death, it
met a different fate. It was turned into meeting
halls for Östgöta Nation of Uppsala University
and currently conveys little of Linné’s spirit.
“That is something our Orangery will have,”
says Lars Nexe. “At the end of April, six
prospective horticulturists and landscape architects from Alnarps Trädgårdsskola shall begin
planning the botanical garden, which shall present over 800 species of flowers, medicinal plants
and useful plants.” Linné is surely smiling down
from heaven as he looks down on the events in
his native district.
The sheet metal crowning the roof of the
Orangery was donated by Lindab Steel and laid
by student sheet metal workers Henrik, Jonas
and Alexander from Kattegattskolan in Halmstad.
“I would like to express a warm word of
thanks to Lindab for their contribution to this
cultural project that is important to all of
Sweden,” concludes Lars Nexe.
“The Orangery that is now under construction
was designed by Linné himself and received the

International Centre for Indoor Environment and Energy
World leading
indoor climate research
When you talk about indoor climates or ventilation systems, these terms sound so technical that you sometimes forget the human aspect. That’s something the world’s leading institution for indoor climate research – International
Centre for Indoor Environment and Energy – has not done. Here is where people’s experiences of ventilation and
indoor climate are put centre stage, with the entire research undertaking revolving around mapping out people’s
experiences and reactions to changes in temperature, air flows and other factors related to the indoor climate.
”W
e are without a double the
world’s leading institution in
our area – defining construction parameters and developing innovative solutions for the healthy, comfortable and productive indoor climate,” says Bjarne Olesen, professor and head of the Technical University of
Denmark’s (DTU) institution International
Centre for Indoor Environment and Energy
(ICIEE). He can definitely justify this statement
as the institution enjoys an extremely good reputation as both a research institute and standardisation authority.
Professor Ole Fanger, a renowned indoor
climate researcher, is behind a great deal of the
institution’s success and the palpable attraction
indoor climate researchers the world over have
for DTU’s large campus north of Copenhagen.
ICIEE is not just known for its method of conducting research based on people’s experiences
and needs, but also plays a great role in the
development and definition of the standardisation criteria for indoor climate and ventilation
that are emerging, partly due to the Energy
Directive of the EU Commission.
Since January 2004, ICIEE has been led by
professor Bjarne Olesen. He was professor
Fanger’s first doctoral candidate at the institution. After over 10 years in industry service, he
was drawn back to academics and returned to
DTU.
Second oldest institution
The International Centre for Indoor Environment and Energy, previously known as
Laboratoriet för värme- och klimatteknik
10
(Laboratory for Heating and Climate
Technology) has been around for more than a
hundred years – making it Europe’s second oldest institution for heating and climate technology. The Herman Rittel institute in Berlin is just
one week older. “Research on indoor climate
and the human need for a good climate really
took off at the end of the 1960s and beginning
of the 1970s,” explains Bjarne Olesen. “That is
when Professor Fanger wrote his dissertation on
thermal comfort, after which he began his successful leadership of the institution.”
Six years ago marked the start of an
extremely intense period for the institution
when after a competition the Danish government awarded DTU a grant from its scientific
technology research fund in order to build up a
leading international centre for indoor climate
research over a ten-year period. “The first five
years were characterised by great efforts with
intense research and completion of our climate
chambers and laboratory facilities,” continues
Bjarne Olesen.
This grant has done much to build the institution’s reputation on an international level and
has provided the long-term conditions that are
critical to successful research. “Because of its
longevity, the research of the past six years,
which primarily focused on air quality and ventilation studies, has attracted researchers from the
four corners of the globe. There are now at least
15 nationalities represented here,” says Bjarne
Olesen, switching at the blink of an eye between
Danish, English and German when researchers
and students need questions answered during
the interview.
Industry sponsors
“As we are now into the second five-year period, we are starting to see this funding gradually
reduce in preparation for its end in 4 years.
Since DTU will not immediately take over the
costs of the projects we are running – and for
the 60 people tied to ICIEE – new financing
forms have become more critical. We have, for
example, completed a number of research projects for ASHRAE in USA and have received
financial support from several industry sponsors.”
We have also conducted industrial research
totally financed by the company commissioning
the project. We are currently conducting climate
research for an airplane manufacturer. For this
purpose, we have constructed a complete flight
cabin in the institution’s laboratories so that
tests can be carried on subjects over the full
range of “flight” conditions.
Lindab has recently joined the ranks of our

as accurate as possible. Thus, the research environment must be as similar to the work environment as possible and the production activities
we measure must be actual, real and not fake

measurement, testing was conducting in the
company’s own office environment. By measuring the number and length of calls, we could
measure the parameters that were directly tied
to productivity. Filter replacement and an
increase in the amount of ventilation each generated a significant improvement in productivity.”

the same conclusions in similar tests. Getting
this knowledge and experience out to not only
advising consultants and design engineers but
also ventilation and climate equipment manufacturers is of the utmost important, feels Bjarne
Olesen. “These are the players that must convince proprietors and investors of the advantages.” More and more investors already understand that a good indoor climate affects not only
the rent one can receive but also improves the
possibilities of renting out the premises.
“Backed by these research results, the outlook
for an improved indoor climate is looking
bright.”
Personal ventilation
Another important area in which the institution
has played a leading role is research in “personal ventilation.” “Because of the location of the
diffusers, in most cases the air blends with existing air before it reaches the user,” says Bjarne
Olesen. “What would happen if the diffuser is
instead positioned near the person – at the desk
or directly above or at the work station – so that
the supply air has the shortest possible route to
the user. Since the air could then be aimed more
precisely, this would result in a reduction in air
volume and thereby energy costs. Analysis of
what occurs in the “inhalation zone” is then
quite significant since, for example, the individual’s body temperature affects the air flow from
the ‘personal’ diffuser.”
The institutions “models” are well known in
this part of the research world not only for their
appearance, but also for their ability to measure
air flow around the body. “These mannequins
allow us to measure ‘skin temperature’ in 16 different zones of the mannequin’s body. We can
then turn the process around and regulate temperature in these zones to see how air flow is
affected in a precise manner. Because they have
‘lungs’ that they breath with through the nose
and mouth, we can use trace gases to estimate
the likelihood that a person’s exhalation air
reaches another person’s inhalation air. And,
above all, we can measure how this is affected
based on whether displacement ventilation or
mixing ventilation is used. Naturally, this provides interesting information for reduction in
the spread of germs and the like.”
Some are much more sensitive to a poor
indoor climate than others. These individual differences that vary from person to person are
just one part of the significant results of the
research conducted in this area. “This means
that the idea of ‘personal ventilation’ is becoming more and more interesting. Especially as it
means that each individual can affect their own
‘microclimate’ in a better manner,” explains
Bjarne. “A better microclimate makes it more
likely that one will spend more time at the work
station.”
12
Research on “personal ventilation” is conducted in a large laboratory facility, giving full control
of all test parameters.
Now that the positive effects of “personal ventilation” have been mapped out relatively well, all
that remains is to develop the technology and
solutions that make this possible in practice. In
this context, collaboration with the industry will
play an important role.
Energy Directive
The institution’s research results are not only
important as a selling point for better ventilation systems. “Just as important is that it allows
us to directly affect and develop that standards
governing usage and design of ventilation systems. We are helping set the level of the different climate parameters that define an indoor
environment in climate terms – temperature,
humidity, air speed, number of particles, etc. –
and use our research results to set suitable intervals for minimum/maximum values,” continues
Bjarne Olesen.
1 January 2006 all European buildings must
have an energy declaration in accordance with
the Energy Directive. “Here, each country sets
its own limits for the amount of energy that may
be consumed. Previously, requirements mostly
focused on how walls, ceilings, windows and
doors were to be insulated. Now, a report on
energy consumption and CO2 emissions shall be
given for the building as a whole and its installations,” concludes Bjarne Olesen. “This puts a
whole new focus on ventilation systems, their
design and energy consumption. For example,
the directive lays out that no energy saving may
be implemented if it negatively impacts the
indoor climate. From ICIEE, we participate with
a group that is working to draw up the guidelines, limits and calculation methods that are to
apply for indoor climate requirements. That
these requirements are on the increase is quite
clear already today. We can see that people feel
better and do better in a better indoor climate.”

silver in the ventilation fights bacteria
4000 years B.C. the Egyptians began storing their water in silver-lined vessels. In 16th century
China, the emperor ordered that tableware and cooking utensils made of silver were to be used
exclusively. Three hundred years later, a decree from the Vatican declared that all Communion
vessels were to be made of silver. Today, silver compounds with their well known antibacterial
effect are an important component of modern healthcare.With the new product program
Lindab AgION™ there is now also a duct system that makes use of silver’s ability to keep bacteria and mould in check. A solution highly suitable when demands for hygiene are extra large.
S
ilver has been used for thousands
of years to reduce the risk of
spreading germs. It’s not by chance
that silverware came into use. As early as the
6th century, people in China discovered that silver was the most hygienic thing to put in your
mouth. Today silver is put to use such fields as
healthcare, where catheters, eye drops and burn
salves benefit from its antimicrobial properties.
In a ventilation system in which ducts and
components are maintained and cleaned regularly, there is usually no breeding ground for
bacteria. But, in environments with extremely

can quickly lead to great difficulties. For these environments, there
is now Lindab AgION™, a duct
system that makes use of silver’s
well known antimicrobial effect.
Natural components
The silver ions are released from the matrix in
the presence of other ions in the ambient
moisture in which bacteria and mould can live
and multiply. The released ions choke the oxygen supply to the cell, destroy the cell walls
and hinder the genetic reproductive ability
without affecting resistance. “It is important to
emphasise that this is a natural and inorganic
component. With chemicals, there is a risk that
the bacteria could mutate and become resistant.
Laboratory trials have shown that bacteria cannot mutate and resist the effect of the silver ions
since AgION™ stops them in the three ways
mentioned previously,” continues

On the beach and fjord
holiday homes in lightweight construction technology
generate new employment opportunities
Taking inspiration from the fjord’s old fisherman’s shacks, the new holiday homes in Hvide Sande
Sluse cast an eye out to the glittering water. Initiative, good ideas and lightweight construction
technology created not only more housing opportunities – on both land and water – for some of
the close to 60,000 tourists that choose to visit the west coast of Jutland. They also generated
more employment opportunities and new businesses for the old traditional shipyard.

S
oftly rippling white sand dunes, gently billowing sand rye grass and
terns flying playfully over a clear
blue, inviting North Sea. It sounds like somewhere you would love to let both body and soul
escape for awhile. Add a traditional Danish fishing area with black fisherman’s shacks and a traditional boatyard in which the masts of the renovated old boats proudly rise to meet the sky
and the dream almost reaches perfection.
Unfortunately, even dreams can have their
flaws.
The community of Hvide Sande on the
southern west coast of Jutland with its 3,000
inhabitants has all of the wonderful things
described, but also suffers from increasing
unemployment as a result of the decline in the
fishing industry. “This situation was rather troubling, but at the same time a challenge since we
clearly saw great opportunities for our fantastic
coastal area. Each summer, the “population”
swells to 60,000 if we include all of our tourists
in the count,” says Henning Davidsen, project
manager at Holmsland Klit Turistforening
(tourist association) and the man behind the
large and successful tourist undertaking with
summer cottages that is now entering its second
phase.
Protected harbour-side land
When the tourist association was granted access
to a larger beach area on the side of Hvide
Sande that faces Ringkøbing Fjord, an exciting
project could be put in motion. “There is an old
tradition in Denmark that areas belonging to
government harbours may only be used for harbour-related activities. But, since our harbour

was being turned into a municipal harbour, new
opportunities suddenly opened for using these
areas in a way that benefited both the residents
and the tourists,” explains Henning Davidsen.
“From the tourist association’s part of
things, we were quick to present ideas for a holiday home project – Hvide Sande Sluse – in
which local craftsmen would construct and build
the facility. In the subsequent discussions involving us, municipal representatives and others
involved, it was natural to try to involve the
Hvide Sande Skibs- og Baadebyggeri shipyard
in the production of the buildings. Especially
when we decided that the project would be built
using lightweight construction technology. The
shipyard had long, vast experience with both
steel and wood. The puzzle pieces began to fall
into place,” continues Henning Davidsen.
Attractive lightweight
construction technology
Through contacts and trips to Sweden, Henning
Davidsen had seen that this type of construction
technology was gaining a lot of ground and
would most likely be an excellent fit for the
Hvide Sande Sluse project. “If were could develop knowledge and expertise in this area in
Denmark, there would be even greater opportunities,” continues Henning Davidsen. “At that
time, we contacted Lindab and, together with
our architecture firm Cubo Arkitekter A/S,
determined that lightweight, prefabricated
facade and roof elements were the way to go.
This prefabrication was done by the Seasight
department of Hvide Sande Skibs- og Baadebyggeri together with a local construction company. This gave the community new, sought-after
employment opportunities.”
Inspired by fisherman’s
shacks
So far, 34 holiday homes have been constructed
and sold to private individuals. The next phase is
underway. “Either the owners use the homes
themselves or we at Holmsland Klit Turistforening help them rent out the homes,” contin-

The holiday home project at Hvide Sande Sluse and Seasight’s houseboats have been a great success so far with sold out homes and boats. Happily, it
has also helped create more employment opportunities on the west coast of Jutland. Lindab’s lightweight construction technology plays a central role in
both the holiday homes and the houseboats.
ues Henning Davidsen. “Since we are located so
close to the German border, this is a popular
area for Germans, who rent several of the
homes.”
Through the architecture firm Cubo
Arkitekter A/S, the holiday homes of the Hvide
Sande Sluse project have been given a look that
ties in well to the local construction tradition.
“We took inspiration from the small black
shacks found at the fishing villages around Ringkøbing Fjord. These are used by fishermen to
store tools and to live in once spring has come.
The black colour naturally comes from the tar
used for hawsers and nets. What was left over
ended up on the shacks’ facades,” says Helge
Davidsen, head architect at Cubo Arkitekter
A/S (yes, he’s Henning’s brother). “The result
was a small-scale settlement with long and narrow buildings with window-less long sides whose
large glass gables face the south and the
sparkling fjord.”
technology in focus – namely production of
houseboats. “No one in Denmark had ever seriously considered houseboat production, but we
considered it a vast, interesting market in
Denmark, Sweden and Germany with all the
channels and exciting quay spots,” says Henning
Davidsen. “The entire operation was run by the
company Seasight, which is also situated in the
old shipyard. I think it is a positive sign that we
were able to build up expertise and skills in two
growing operations in a short amount of time.
Lindab played an important part in this development. We have established an excellent collaboration with them and built up a relationship
that I think has a lot left to give. Lindab’s
expertise in lightweight construction technology
combined with the support and reliable deliveries they presented has been of great significance.
There may still be hope for Hvide Sande,” he
concludes with a Danish smile on his lips.
New project
Seasight is a department within Hvide Sande
Skibs- og Baadebyggeri, which since 2002 has
been producing building elements for Hvide
Sande Sluse and has been responsible for the
Parallel to the Hvide Sande Sluse project, an

industrial manufacture of houseboats for the
Nordic and Northern German markets. “Right
now, we produce houseboat elements for several
other companies and shall soon begin production of elements for 20 new holiday homes,” says
Niels Møller, manager at Seasight.
There is currently a great interest in both
renting and buying houseboats. The problem is
finding enough harbour spots. “There are currently six sold houseboats here in Hvide Sande
in a completed environment with jetties, gangplanks, parking spots and areas of land. This
means that we now have a good ‘model home’
that can attract interested parties from areas
such as Northern Germany,” says Niels Møller.
“The houseboats we make now are maintenance-free for 10 years before they must be
taken to the shipyard for painting and maintenance. The largest houseboats we currently manufacture have about 145 m2 of living space, have
several terraces on different levels, can be
equipped to meet the customer’s desires and
are, of course, adapted to the Nordic climate.”

Tropical Island
Spectacular attraction in northern latitudes
The famous legend of Mohammed and the mountain – “If the mountain won’t come to Mohammed, Mohammed will go to the
mountain” – deals with the need to accept the impossible, and also about finding new solutions to “insolvable” problems.When
Malaysian businessman Colin Au saw the need for tropical warmth and atmosphere in the cooler Europe, he simply brought the
tropics here and created Tropical Island – northern Germany’s new island in the sun and heat.
W
hat do you do with a zeppelin
hangar that is big enough for
eight (8) football pitches, tall
enough to stick the Statue of Liberty in standing
up, and the Eiffel Tower lying down – if you
don’t own a zeppelin? Malaysian businessman,
Colin Au, found the site just outside Berlin perfect for building the world’s largest indoor
theme park. Complete with sandy beaches, bungalows, restaurants and an entire rainforest full
of flowers, birds and butterflies. “You know,
Berlin is a bit cold nine months out of the year,
and most of the people living in the area just
can’t fly off to Cuba for the weekend,” says
Colin Au. His idea was “to do something about” those gray days, the rainy
weather and the grumpy moods that
are not at all untypical in Germany and Europe.
“Germans often dream about travelling to tropical lands with friendlier climates, higher temperatures and a total absence of rain.” The problem
is that most have neither the time nor money to
travel abroad for expensive holidays. That’s
when I got the idea for Tropical Island,” says
Colin Au.
“The Tropics” come to Europe
With his experience from running Star Cruises,
Asia’s leading cruise line, Colin Au simply
turned the cruise principle on it’s head. Instead
of shipping people to the tropics, he would now
ship the tropics to the people.
Just under the roof, at nearly 107 meters
height, you get an interesting view of
Tropical Island’s facility, with South Seas’
water and beaches (to the left), the tropical
rain forest (middle) and the Bali Lagoon
(right), with both waterfalls and grottoes.
16
When the basic idea itself was hammered out, it
was time to find a suitable place to put “the
Tropics”. In his quest for the right place, a
German acquaintance tipped him off about the
perfect solution. In Brand, just outside of Berlin,
stood the enormous CargoLifter hangar, empty
ever since that business became insolvent. At
that site, once East Germany’s largest military
airbase, CargoLifter had erected an enormous
hangar for starting zeppelin production. “We
bought the facility in 2002 from CargoLifter AG,
and after investing nearly 70 million Euros via
Au Leisure Pte Ltd. and Tanjong PLC, we were
able to open the doors to Tropical Island in
December, 2004, and invite in guests, the
press and employees to the 360-metre
long, 210-metre wide and 107-metre tall
dome,” says Colin Au. “They got to experience
nothing less that the heat, light and the complete
feeling of a Caribbean island.”
Happy visitors
The gigantic dome, which is the world’s largest
self-supporting structure, has a floor area of
over 66.000 m2 and an indoor temperature of 25
to 28°C. The temperature of the water in the
Bali Lagoon is a delightful 32°C, while those
choosing to swim in the South Seas have to content themselves with a more modest 28°C! Add
to that a humidity of about 50% and the result
is an attractive climate for both visitors and the
more than 500 different species of tropic plants
that are represented.
An average of around 4,500 visitors a day
have come to Tropical Island since it opened on
December 19. “We expected between 3,500 and
4,500 visitors per day,” says Günter Mosler, project leader for Tropical Island. “During the winter, however, the number of visitors could reach
as many as 9,000 on some days. The surveys we
ran to measure visitor appreciation of Tropical
Island have shown very good results. 46% give
the facility a rating of ’excellent’ and 47% rate it
as ‘good’. You really can’t expect a better result
than that, nor did we.”
Visitors stay an average of 5 to 6 hours, and
have access to the two large bathing lagoons,
with sandy beaches and deck chairs, seven

addition, we have worked with Lindab on several large projects with very good results, and have
established an excellent working relationship.
The Tropical Island project was no exception;
Lindab succeeded as usual to manage both the

that the work on the pools could begin by late

architect’s invisible suspended ceiling dream
Clean, smooth surfaces without disruptive elements are with few exceptions high on the architect’s list for the
design of the suspended ceiling. The problem is that it is in this area that solutions for acoustics, ventilation, heating/cooling and lighting must share space. A bright idea from Lindab – and collaboration with acoustic ceiling manufacturer Ecophon – gave rise to an invisible solution. Technology and aesthetics in a unified concept – Celo.
A
rchitects often have definite
opinions on everything involving
their discipline. It would be
strange otherwise. Even if these opinions don’t
create problems, they can create enormous challenges for suppliers of components and solutions for modern building construction.
Take, for example, the suspended ceiling.
Here is where equipment for ventilation, heating/cooling, lighting and fire protection must
often share space. “Architects often feel that
nothing should be seen, at least as regards ventilation and heating/cooling,” explains Göran
Hultmark of Lindab Climate in Askim. “It must
be aesthetically pleasing while completely meeting needs for lighting, ventilation, heating and
room acoustics.”
Invisible solutions
“When we met with suspended ceiling manufacturer Ecophon in late autumn 2003 to better
synchronise Lindab’s solutions for ventilation
and heating with Ecophon’s suspended ceiling
system, the desires of the architect were on the
agenda. During the meeting, Ecophon designer
Juha Huhtilainen continually returned to the
architect’s desires for increased aesthetics,
“invisible” technical installations and a smooth
suspended ceiling. During the meeting Ecophon
also presented its efforts in free-hanging units,
i.e. where the suspended ceiling hangs down
freely from the wall and creates a column
between the ceiling and wall. That’s when I
starting wondering whether we actually could
make our products more hidden.”
Fruitful collaboration
This was the start of an extremely fruitful joint
development project between Lindab and
Ecophon which now, about 18 months later, has
resulted in the launch of the suspended ceiling
system Celo. Celo is Latin for “hide or hidden”.
That is exactly what the ventilation baffle Celo
22 from Lindab is – completely invisible. By utilising the column between the wall and suspended ceiling and there release cooled air down into
the room, the baffle could be positioned in such
18
a way that it is completely out of sight. Together
with Ecophon’s other Celo products, there is
now a complete system that fulfils the architect’s
desires in a new, exciting manner.
“This is our and Lindab’s first joint development project,” says Anna Jonason, development
engineer at Ecophon. “We often ‘met’ at the suspended ceiling. There was much to be gained if
we could together find solutions for better synchronisation of our respective products that also
please the architect. That was the starting point
of our collaboration and exactly what we were
able to achieve.” Ecophon contacted several baffle manufacturers in 2003. “But, since Lindab
was not only a leader in this technology but also
showed the greatest interest, the choice was simple,” explains Anna Jonason.
In the autumn of 2004, Lindab presented
these ideas at an international architecture
forum in Seville. “All of the architects we were
able to talk to were fired up with enthusiasm,”
explains Göran Hultmark. “Therefore we
believe there is great potential for the Celo concept. The initial phase for new products is, however, quite long. It takes six months to a year

figures.” During the development work,
Ecophon also received confirmation of the great
interest for the Celo concept via architect contacts.
Simple coordination
Celo 22 is based on a well known, proven technology from Lindab in that it is based on a half
‘Professor’ baffle, one of Lindab’s more well
spread baffle products.
Combining the suspended ceiling, baffle,
extractor unit, lighting, etc. into an integrated
system, the all-important coordination becomes
significantly simpler. “Everyone involved – from
the architect and client to project planner, procurement officer and installer – can now take
pleasure in a complete suspended ceiling concept that creates both a good indoor climate and
good room acoustics. Through the use of Celo,
technology and aesthetics can successfully work
together,” says Jonas Holmberg, market coordinator for Lindab waterborne products.
Patent-pending technology
The newly developed ventilation baffle Celo 22
is positioned above the lowered Celo suspended
ceiling. The technical solution for Celo 22 is
based on a unique patent-pending technology in
which the cooled air is sent down through an
outlet column in the suspended ceiling along the
entire wall and then on down to the floor. “The
air has a fan-shaped spread, resulting in low air
speeds in the occupancy zone,” explains Göran
Hultmark. “The air exchange efficiency in the
room is also good since the clean, cooled air is
slowly sent down along the wall and down
toward the floor while the extractor unit is
located above the suspended ceiling.”

Wikers Plåt – loyal Lindab customer with extensive knowledge
Wikers Plåt AB is a distinguished company that has been in the sheet metal industry
since 1948, when sheet metal worker Östen
Wiker started the company in a cellar in central
Ludvika. Today the company has about 20
employees with projects being led by Jens Pettersson. “I’m keeping the family business alive –
Östen Wiker was my grandfather,” he says and
explains that ventilation contracts – project planning to delivery, installation and commissioning –
constitute the core activity, supplemented with
delivery and installation of builder’s hardware,
drainage, construction and roofing sheet metal
work.
For many years, Lindab has supplied
Wikers Plåt not only ventilation products but
also roof drainage and other construction sheet
metal components. “Lindab always takes care
of everything for us,” says Jens Pettersson. “If
you add good prices and great product assort-
ment to the picture, you get a supplier you just
don’t want to be without. In addition, Lindab has
the most easily installed system when compared
to other duct system manufacturers.”
Project planning and drawing tool CADvent
has been used in the company since 1996. “We
have followed the program’s development and
continually use it for our ventilation projects,”
says Jens Pettersson. “The program has been
developed into an extremely good aid and useful
tool for our project planning. We think that CADvent’s greatest strength is that it allows you to
draw ‘in reality’. We draw in the right dimensions
and with products that have the correct measurements. This way, we avoid surprises when it is
time for installation.”
struction of 48 service apartments as well as
common rooms in one floor totalling 4,500 m2.
The client was Riksbyggen with PEAB as general
contractor. Wikers Plåt was responsible for
project planning and installation of the ventilation
system as well as control and monitoring. The
company was also responsible for roof drainage,
construction sheet metal and forging.
Lindab delivered the complete duct system,
all thermal and fire insulation as well as roof
drainage and construction sheet metal to kv.
Grönsiskan.
“Most of what we need we can get from
Lindab,” concludes Jens Pettersson. “The only
thing missing is a fan unit. But, you can’t have
everything.”
One of the latest projects is retirement home
kv Grönsiskan in Ludvika, comprising new con-
Jens Pettersson and some staff members in front of the
company’s premises in Ludvika.
Retirement home kv. Grönsiskan in Ludvika has an unmistakable Lindab stamp. With the ventilation drawn in Lindab’s CADvent, and the entire
duct system, insulation, roof drainage and construction sheet metal delivered by Lindab in Borlänge you wouldn’t expect anything less.
HLD – new low displacing device for
Michelin in Romania
HLD – high level displacement is a
new type of perforated device for large amounts
of air primarily developed for industrial
applications. 56 HLDs were
recently delivered and installed
at Michelin’s facilities in
Romania. “There was competition with another supplier who
was already in place, but we
succeeded in bringing home
this interesting order,” explains
Jesper Vartau Hansen of
Lindab Denmark. “After being
contacted here in Farum by
Adrian Mocanu of Lindab
Romania with an inquiry as to
whether we could produce a
device that could replace that
of the competitor, we quickly
20
developed the new product HLD.
Thus, we can now offer a displacing
device for industrial applications that
makes the supply of
large amounts of air
possible. This is a
product that is greatly in
demand, simple and easy to
clean. We have filled a gap in
our device range.”
HLD’s design provides
choice in the control of air flow.
“It can be directed horizontally,
which is the norm when cool air
is to be supplied,” explains
Jesper Vartau Hansen. “The
device can also be set for vertical air supply in a heating situation.” HLD can be delivered
with either manual or motorised control of air
supply angle and is installed 3-4 meters over
the floor.

CADvent 4.0 with many new features
When Hotel Nyborg Strand was set
to add to its conference facility Glassalen, Ventilationsgruppen in Odense ran into trouble. There
was just no room for silencers. “We could, however, offer their project manager Eng. Sten Nicolaisen a special solution with calculated damping
effect,” explains Ove Boisen of Lindab Denmark.
“By using Lindab’s new Silentduct, the system
could produce its 5,000 m3/h while at the same
time fulfilling the acoustic standard of 35 db(A) in
Glassalen with no problems.”
The new version of Lindab’s well
known ventilation program CADvent is currently
being launched in a number of European markets. “CADvent 4.0 has been further developed in
500 points compared to version 3.5,” explains a
pleased Björn Broberg, product manager of ITline. “CADvent has always
been fast, precise and comprehensive. Now it is even better in all of
these areas.” Here are some of the
most important new features.
“This type of system has been available in
some of our markets for some time,” explains
Jörgen Andersson, project manager for
Acoustics. “We are the first to combine the
product type with extensive know-how. By
measuring our Silentduct products in the
acoustic laboratory in Farum, we can offer our
customers exact dimensioning and calculation
of the effects surrounding the selected
Silentduct solution. The system is primarily
intended as a problem solver when the building
height is not known, but also provides aesthetic
solutions as the duct can be selected with a
smooth outer diameter and the silencer cannot
be seen from outside.
Auto routing. Through a developed
Continue command, set components
in directly via the command line. This
generates markedly quicker product
selection and more exact drawing
functions.
New products. A number of new products can
now be drawn in and calculated in CADvent
through increased information from Lindab’s
super database. Information for dampers, pressure and suction chambers as well as devices
and silencers is now retrieved online
from the super database and provides technical data of significantly
higher quality. For example, the new
device Facilis is included.
CADvent 4.0 is now being
successively released in
markets across Europe, giving HVAC consultants

Facilis FCL – new, patent-pending unit makes things easier for everyone
Facilis is a new series of ceiling
unit for supply and exhaust air that really takes
development a giant leap forward. “The simple is
often genius,” says Fredrik Engdahl, head of
product area Comfort in the Ventilation business
area. “Our new Facilis FCL unit is a product with
a number of advantages for architects, HVAC
consultants, installers and proprietors alike. The
lowest height on the market, a very low acoustic
level in a great pressure area and no need for
adjustment upon installation or after cleaning are
just some of the important advantages. And this
is without being a complicated product.” Facilis
FCL, which is a combination of device and box,
is made to fit 90% of the suspended ceilings on
the market and is very simple to install.
Facilis FCL is delivered completely dimensioned, preset to the desired amount of air at
the desired pressure. “The large pressure area
and the low acoustic level makes it possible to
get enough pressure over the device, which is
why it is not necessary to set individual units.
You can instead make checks via sampling,”
continues Fredrik Engdahl.
How Facilis works
Facilis FCL can be equipped with various
bottom plates from Lindab’s DesignLine range
based on the desires of the architect. The device
is delivered ready for installation for the most
common 600x600 ceiling systems. Being able to
combine the architect’s aesthetic desires with
the installer’s technical requirements is a great
advantage. “The fact that Facilis is easy to clean
since internal components can be easily
removed without tools doesn’t hurt,” concludes
a pleased Fredrik Engdahl. The product is cur-
When the air flows through the connection duct (1), the perforated plate (2) distributes the air evenly in the pressure
chamber (3). The pressure drop plate (4) is equipped with
nozzles and creates the desired drop in pressure, subsequently leading the air in the desired direction through the
impulse chamber (5), where the optional bottom plate (6)
distributes the air out into the locale. The acoustic insulation
(7) ensures good damping in the device.

From Vent to Safe at IKEA Czech Republic Police hq. with
Lindab technology
It’s indisputable – IKEA, Swedish
steel and Lindab have not only the same national
origins, but also the same entrepreneurial spirit at
their core. We won’t say whether this is the
reason that the fourth IKEA department store in
the Czech Republic is being built with the help of
solutions of Lindab. The fact is that the installa-
after pressure from both us and the fan supplier
we managed to convince them of the advantages
of switching to Lindab’s rubber-sealed system
Safe,” says Jindrich Chrast, regional director at
Lindab who, together with sales manager
Stanislav Nemecek, succeeded in implementing
this change. “Now, IKEA’s new department store
in Prague has a better sealed, more energy efficient ventilation system. I’m sure no one will disagree that this makes for better total economy in
the long-term.”
Today, the new IKEA department store,
which opened its doors 16 December 2004, is
filled with not just Billy, Lack, Tomelilla and all of
tion, which has now been completed by Czech
ventilation contractor Luvex s.r.o., has been
approved on all points by those responsible for
the project at IKEA. “It is, of course, quite satisfying to once again have developed a total solution that not only received IKEA’s full approval,
but also helped us yet again supply our longterm customer Luvex with the product solutions
and support required to win the approval of the
Swedish furniture giant,” says Jan Simsa, manager of business area Ventilation in the Czech
Republic.
The original project planning involved

Like Sweden, Japan really gets its fair
share of precipitation. That is just one of the reasons that two containers of black Rainline roof
drainage have now been shipped from Förslöv all
the way to Japan. “The Japanese importer
Yamat reports that the installers that have
installed the products thus far have appreciated
the assortment, quality and simple installation,”
says Jan Tomberg, pleased product manager for

the other famous IKEA products. A complete circular duct system from Lindab fills at least parts
of the suspended ceiling, providing the 44,000
square meters and up to 5,000 daily visitors with
the right dose of fresh, clean air.
Since the summer of 2004, Peab
has been working to build Helsingborg’s new
police headquarters on commission of property
company Norrporten. Located near the northern
entrance ramp, motorists on their way to the
centre have been able to follow the progress of
construction. The building has six floors and
room for 600 police employees.
Lindab has delivered to its customer
Danogips outer wall joints for 2,400 m2 as well
as facade and partition wall joints for a surface
of approx. 12,000 m2.
The consultant Byggteknik in Skåne was
responsible for project planning of lightweight
construction components. “Lightweight joints
have a big advantage over wood due to their
insensitivity to moisture,” says Håkan Mårtensson of Byggteknik in Skåne. “That is why Peab
and Norrporten worked with us to switch from
the system documentation’s wood joints to
lightweight steel joints.”
Prize to Lindab
Poland
On 1 December 2004 Lindab Poland
was awarded the distinction Building Company
of the Year 2004 – awarded for the second time
by the Polish trade journal Kalejdoskop
Budowlany. The prize is awarded to the company the jury considers the strongest as regards
product offering, quality, customer relations,
marketing and growth. With about 1,000 companies in the Polish building market, with competitors such as Hochtief, Knauf and Rockwool, it is
a great honour for us to be counted as a leading,
reliable and innovative company,” says Jacek
Wozniczka, Lindab Poland. “We consider the
recognition we have received from external auditors very valuable and stimulating.”

High “Lindab density” in Kostamucksha
Russian Karelia is not merely beautiful countryside bordering Finland and with
St. Petersburg to the south. It is also an area
where foreign investments are becoming ever
more common. Together with its partner, UTS,
Lindab has been gaining an ever stronger foothold here since 1994, and UTS has been very
active in introducing and spreading Lindab’s light
construction technology within Russia. “UTS now
has enormous experience and knowledge in this
field,” says Igor Tatynski, regional manager for
Lindab Profile in Russia. “There are probably
more Lindab buildings per square kilometre in the
little mining region of Kostamucksha than anywhere else in the world.”
Most recently, UTS in collaboration with
building contractor TEKOMPROOF, has erected
a second factory structure for the Finish subcontractor, PKS Group, with lorry manufacturers
such as Volvo, M.A.N and Scania on their client
list. “This Building System delivery from Lindab
had exactly the quality, security and quick delivery – and assembly time, too – that we and our
client, PKS, have become used to,” says project
manager Victor Efremkin at UTS/TEKOMPROOF.
“Together with the first factory, we have now
delivered more than 11,000 m2, and another
8,000 m2 will begin during 2005.
Second phase completed at PKS’ Karkhakos factory
The second phase at the Karkhakos PKS
cable and accessories factory for lorries in
Kostamucksha was inaugurated in September, 2004, by Karelian President Sergey
Katanandov, along with representatives from
Finish authorities.
Not content that UTS and TEKOMPROOF have soon erected nearly 19.000 m2 for
the very satisfied PKS Group, UTS/Lindab
are also erecting a new shopping centre in
Kostamucksha, and preparations are underway to erect a large forest industry and a
mining facility. Residents of the area are likely
getting accustomed to seeing Lindab’s steel.
Increased space with expanding light-construction technology
Pre-fabricated buildings have long
been a common feature in the Czech residential
sector. Many of these multi-dwelling
blocks are currently in need of extensive renovation. Thus, the opportunity
to combine renovation with enlargement, and thereby increasing residential space, is of great interest, at least
for the larger blocks. “We have delivered a two-storey modular addition to
the large renovation project in Stará Boleslav,
25 km north of Prague,” says Petr Hynst, lightconstruction specialist for Lindab s.r.o., in the
Czech Republic. “As usual, it was quite
a challenge for the architects, constructors and we here at Lindab, but the end
result was six, new, attractive flats, each
with a living space of 85 m2.
The addition was built entirely of
self-bearing light-construction technology consisting of Lindab's RY steel
studs, external wall runner SKY, as well as steel
C and U beams for the lower, weight-bearing
storey. The spandrel panels were prefabricated
and hoisted into place. The architect chose
Lindab’s metal tiles for the roof cover system.
“All this not only made the additional section
easy to assemble, but also at a low overall
weight which the original structure could handle,” concludes Petr Hynst. “In addition, the
property owner got six new tenants, at the same
time as the old ones were happier.”
Fast, light-weight,
ergonomic
Renovations with light-construction technology provide many
advantages, such as fast
assembly, great flexibility and
easy adaptation, along with low
dead loads. Something that both
installers and the environment
appreciate is the reduced waste
and the cleaner work site that
results when all the components
are delivered factory-made or
pre-assembled.
