About Guardian Industries:
Advanced Architectural glass
Guardian Industries is a leader in the
international manufacture and supply of clear
float glass and associated float glass products.
We are one of only three companies
manufacturing float glass in the UK, with over
£100 million invested in a float glass line in East
Yorkshire.
Guardian Industries was started in 1932 in
Michigan, USA. Our UK operation in Goole
has full support in everything that we do. Our
popular products include our SunGuard solar
control and ClimaGuard thermally insulating
glass ranges. Today it is more important than
ever to specify the right glass for the right project.
Guardian glass products feature all over the world
from the tallest buildings to the smallest simple
residential houses.
Specifying the right glass can ensure an
environmentally sound and sustainable project,
that will run on reduced space heating and air
conditioning for many years to come, minimising
energy costs and reducing CO2 emissions. Why
specify costly heating and air conditioning
systems when the fabric of the building and the
glazing you choose can do the main part of the
job for you!
Guardian, as one of the market leaders in the
UK, would like to take this opportunity to exhibit
some of our most popular projects and explain
why glass specification is so important for the
future of all UK and International projects. We
would also like to guide you through the world of
glass specification and provide all the details you
need to access the right Guardian glass products
and information for your projects.

reaches new heights
on the Burj Khalifa
The Burj Khalifa is the world’s tallest building, standing
2,716ft high and we are proud to say covered in more
than 1.8 million square feet of Guardian SunGuard
Solar Silver 20 glass and Guardian ClimaGuard Low
E. The SunGuard Solar Silver 20 glass on the outer
pane of the glazed façade, is the ideal product for the
extreme conditions in the Arabian Desert. There
were many considerations to factor when specifying
the glass, with the extreme heat gains of the desert
sun, preventing a completely glazed building from
overheating is essential! The SunGuard Solar Silver,
has an extremely low g value of just 17%, ensuring
the solar heat is kept out of the Burj. Additionally to
this the SunGuard Solar Silver has an anti-glare shield
which ensures the light from the desert sun doesn’t
cause overbearing glare inside the building.
This specification was also carefully considered due
to the desert temperature swings and the strong
winds, having to cater for the buildings requirement
from the 1st floor to above the 160th floor.
Working in an ideal partnership with the SunGuard Solar
Silver 20 outer pane, ClimaGuard Low E was used for
the inner pane, providing complete performance to
help control the environment inside the building.

architectural glass - A case study
Gunwharf Quay, Portsmouth
For many years high performance solar control
glass was mainly associated with high rise tower
blocks and large commercial buildings. The
traditional reflective aesthetic of solar control
glass was often the key attribute in providing the
finished aesthetic appearance and signature of
large, mainly glazed constructions, whilst also
providing the required performance to help
control the environment inside the building.
However, times are changing and the
performance capabilities and aesthetic finishes
of high performance glasses now far exceed the
expectations we had just five years ago.
No longer do we have to rely on tints and highly
reflective glass to achieve solar control; today
we can achieve exceptional performance with
a much more neutral appearance. With every
improvement we make to our SunGuard products,
we find we are able to create high performance
coatings which not only have exceptional
performance in terms of solar control and low
U values, they also now have ever improving
levels of high selectivity, allowing optimum
visible light transmission and in turn providing
a superbly natural aesthetic appearance. We are
now perfecting the ability to go completely against
the natural grain of solar control products and
The Basque Health Department Building, Bilbao, Spain
produce glasses which can offer complete control
in almost any environment, whilst maintaining
low energy consumption and a good natural
aesthetic appearance.
The Health Department Headquarters in Bilbao,
Spain, is a superb example of modern glazing
satisfying all of the needs of a newly refurbished
building.
With the ever improving advancements in our
SunGuard glass ranges, we are effectively opening
the door to new markets, as we are able to provide
high performance glass which suits all buildings and
developments, giving architects and specifiers the
ability to choose glass products to suit all the projects
they are working on, whether it’s a tower block in
Dubai like the Burj Khalifa or a small domestic
projects looking to help reduce energy costs.
The new glass façade greatly improves the carbon
signature of the building and meets the strict
demands of heritage planning, where certain
characteristics of the building must be maintained,
whilst also dramatically improving the energy
performance of the building as a whole. The
architects Juan Carlos Coll Barreu, had to work
strictly to the city zoning rules and had to maintain
the same type of building with a distinct link to
the building orientation. A double façade is used
to solve all of these zoning rules, dramatically
improving thermal performance as well as acoustic,
fire and safety requirements, whilst also allowing
the natural appearance of the building to be viewed
through the glass façade. In this case the SunGuard
HP Neutral 41/33 glass was used effectively to
wrap the building, which stands in a prominent
positions on the cross roads of the two most
important streets in Bilbao.

West Yorkshire Police
Science Support Unit (SSU)
West Yorkshire Police have recently had their new
Science Support Unit (SSU) completed at Calder
Park, Wakefield. The new building will house
the new state of the art Forensic Investigation
Support Centre of Excellence which will be home
to the Forces Imaging Unit, Scenes of Crime and
Forensics Specialists. The new building began
construction in June 2010, and has taken just 18
months to complete.
The new SSU building has achieved a BREEAM
score of “Very Good”, and incorporates a range of
sustainable features including ground source heat
pumps, grey water harvesting systems, and a fully
intelligent building control management system
to monitor levels of CO2 emissions ensuring the
building runs to its optimum performance.
To help control the environment inside the
building SunGuard High Selective SN 70/41
was used, which provides a solar factor of 41%,
excellent thermal insulation with a U value of
1.1 W/m2K, combined with a very high light
transmission of 70%. This reduces the need for
artificial lighting during daylight hours and
provides a natural interior feel to the building
without the use of obvious solar control glass,
helping to regulate the environment in the
building and reduce demands on air conditioning
and heating.
The SSU also meets the standard for “Secure by
Design” using Guardian Laminated glass, for
safety and security. The insulating glass units
on the project were produced by Dual Seal in
Huddersfield, and were installed by Dortech.
SunGuard High Selective SN 70/41
The North Middlesex University Hospital,
now over a century old, services approximately
250,000 people and is one of London’s busiest
hospitals for acute emergencies. In 2007 the
hospital was flagged for redevelopment to bring
the facilities up to todays standards and beyond,
investing over £100 million in replacing and
updating old facilities.
Improving the environment inside the building was
key in the redesign of the improved facilities, and
to achieve this the right glazing specification was
crucial. The SunGuard High Selective SN 51/28
glass used has exceptionally low U values of just 1.0
W/m2K which ensures optimal thermal insulation,
and a great reduction in down drafts caused from
the normal temperature differential experienced
with standard double glazing. The high level of
thermal efficiency also reduces cold spots around
windows causing discomfort to patients.
Pleckgate High School, Blackburn
The SN 51/28 glass also rejects 72% of solar heat
radiation, reducing excessive heat gains from
the sun which can make rooms uncomfortable.
All of this performance is also combined with a
super neutral appearance providing high levels
of natural daylight in the hospital, reducing the
need for artificial lighting in patients rooms and
wards, and ensuring patients receive optimum
levels of natural daylight.
This glazing specification offers optimum
comfort and helps to achieve a controlled
temperature inside the hospital without costly
demands on air conditioning or heating.
SunGuard High Selective SN 51/28
Pleckgate High School in Blackburn is the first
school to be built as part of Balfour Beatty’s recent
contract with Blackburn with Darwen & Bolton
councils to rebuild 26 schools in the northern
areas by 2015. The contract was agreed at the
start of 2010 at a cost of £450 million. Work on
the first project, Pleckgate High School, started
immediately as the contracts were signed and was
expected to cost around £25 million to complete.
The project was designed by Aedas Architects
who have offices all over the UK, as well as
Continental Europe, Asia, America and the
Middle East. Aedas Architects have created a
www.guardian.com
modern, fascinating school design, which leaves a
lasting impression. The high performance glazing
used was installed by Dortech, and uses SAS
(Senior Architectural Systems) Hybrid – Series
2 Aluminium Timber composite window system
combined with Guardian High Selective SN 62/34
glazing, fabricated into insulating glass units by
Dual Seal in Huddersfield. The Hybrid composite
window system from SAS has a slim profile which
allows maximum glazed area with a very sleek,
contemporary look. The High Selective Super
Neutral glass provides exceptional U values of 1.0
W/m2K, combined with excellent solar control,
and a solar factor of just 34%, therefore rejecting
66% of solar heat gains into the building. This
excellent performance is further enhanced with
its high light transmission of 62%, making the
glazing exceptionally neutral with some of the
best performance available on the market today.
The Pleckgate High School project uses 3,000m2 of
curtain walling and window systems, which were
specified with High Selective glass to help control
the environment inside the building by limiting
solar gain and providing optimum thermal
insulation with excellent light transmission.

A Case Study
In order to continue the
growth of the economy in the
city of Liverpool, English City
Fund (EFC) made dramatic
investment in the new
commercial district,
St Paul’s Square.
This commercial project has been the most
significant for Liverpool in over a decade, and
shows Liverpool’s resilience through extremely
tough economic conditions. Building 4 St Paul’s
Square is the recently completed final phase of
the scheme, and we are happy to say that it has
been finished to the highest standard in Guardian
SunGuard High Selective Super Neutral glass.
Building 4 St Paul’s Square Liverpool, has become
the focal point for Liverpool’s new commercial
district. Standing eight storeys tall and covered
with over 3,000m2 of SunGuard High Selective
SN 70/41 glass, Building 4 St Paul’s Square takes
pride of place, leaving an impression that’s hard
to forget with its stylish, elegant use of angles
and inspirational design. However, Building 4
is more than just stylish and elegant; it joins the
distinguished list of buildings in Liverpool which
have achieved a 4 star level of ‘Excellent’ under
the BREEAM assessment scheme 2006. Building
4 also achieves a high Energy Performance
Certificate (EPC) B rating. This is setting a new
level of sustainability to aspire to for commercial
buildings in Liverpool.
The SunGuard High Selective Super Neutral glass
used on Building 4 St Paul’s Square helps the
project achieve its BREEAM level of ‘Excellent’.
By specifying SunGuard High Selective SN 70/41,
credits were achieved towards the BREEAM
assessment under many different categories.
Energy Category
In the ‘Energy’ category, the low centre pane U
value of 1.1 W/m2K ensures optimal thermal
insulation, whilst a low solar heat gain level of
41% ensures excellent solar control and helps
limit the chance of the building over heating.
This tailored performance combination means
the demands on heating in winter and air
conditioning in summer are greatly reduced,
as the high selective glass helps to control the
temperate environment inside the building.
Additionally, the SunGuard high selective light
transmission of 70% also helps to reduce the need
for artificial lighting during daylight hours, which
in turn helps to reduce the energy consumption
inside the building. All of these factors can help
score highly in the BREEAM ‘Energy’ category.
Gunwharf Quay, Portsmouth Palais Quartier, Frankfurt
The £200 million Gunwharf Quays development,
which is owned by Land Securities, offers 10,000
sq ft of flexible space. The east side plaza provides
300 residential units, including a 30 storey tower
called No. 1 Gunwharf Quays, which is the tallest
tower constructed to date on the south coast.
This development by Berkeley Homes provides
spectacular panoramic views over Portsmouth,
which are unspoilt as a result of using SunGuard
High Selective glass. This combines solar control
and low emissivity in one glass, which is fitted to
over 6000m2 of the south coast building.
The natural aesthetic appearance of the SunGuard
SN 62/34 glass means that not only is the
environment inside the building maintained by
a solar controlled and thermally insulated skin,
but the views are kept as natural and unspoilt
as possible. The environmental impact is also
greatly reduced by the High Selective glazing,
which works to control the environment inside
the building by reducing the consumption of air
conditioning in summer and excessive heating in
winter. This in turn means CO2 emissions are kept
as low as possible.
The leading architectural and integrated design
firm, Scott Brownrigg, have worked closely with
Berkeley Homes to create a building that matches
the stylish and confident surrounding city of
Portsmouth.

SunGuard High Selective SN 62/34
The skyline of Frankfurt has had a dramatic
redesign with the Palais Quartier re-development
which joins Frankfurt’s list of most iconic
buildings. The Palais Quarter is situated on an
area of Frankfurt’s well known shopping mile,
the Zeil, which previously wasn’t accessible to the
public.
As part of the sites rejuvenation, the Thurn und
Taxis Palais (seen at the bottom of the below
image), which was destroyed during the Second
World War, has been rebuilt from the original
architectural drawings, and adds a stark contrast
between todays modern architecture and the
classic roots of this contemporary city.
The towers use Guardian SunGuard High
Selective SN 62/34 and SN 70/41 glasses to
achieve a clear and crisp appearance. These Super
Neutral glasses from our SunGuard range offer
optimum levels of thermal performance, with
U values of 1.0 W/m2K, as well as high levels of
Health & Well Being
Category
Building 4 has also specified complete curtain
walling. Large areas of glazing help to achieve
credits in the ‘Health and Well Being’ category,
as the floor to ceiling glazing design provides a
connection between the building’s users and the
outside, which promotes a healthy environment
inside the building. Additionally, by using the
SunGuard High Selective 70/41, its super neutral
appearance and high selective light transmission
of 70% provides a more natural level of daylight
inside the building. This helps the office workers
to refocus their eyes when working and adds
towards achieving BREEAM credits in the ‘Health
and Well Being’ category.
Management Category
Under the ‘Management’ category, Guardian 10.8
laminated glass, in combination with toughened
High Selective 70/41, helps achieve credits for
security and safety throughout the large areas
of glazing on the building. The use of 10.8
laminated glass in the unit makeup also provides
the necessary sound control in combination with
the buildings fabric, which ensures the required
acoustic performance is achieved.
Waste Category
In addition to this, using glass on any project can
help achieve BREEAM credits under the waste
category. Due to the bespoke transport system
used to deliver glass, there is little-to-no waste
packaging. In addition to this, any cut sizes of
glass used on a project are either returned to the
glass manufacturer or to a cullet supplier. The
waste glass is then recycled into the float glass
manufacturing process and used to produce new
float glass. Where large areas of glass are used,
the potential reduction in construction waste
can help a project meet its target under the waste
management category of BREAM.
Building 4 St Paul’s Square is therefore not only an
attractive addition to the commercial district, it is
also a fantastic feat of sustainable, environmental
and healthy building design which has been
recognised by its BREEAM rating. The façade
fabricator, Linder Facades, has also finished the
glazing to the highest standard with very little
optical distortion despite the whole façade being
supplied in toughened safety glass.

solar control with low solar gain values of 41%
and 34%. The clever design of the building also
makes best use of the high levels of selectivity which
these glasses offer. This allows total visible light
transmissions of 62% and 70% to flood the interiors
with optimum natural light, whilst still providing
exceptional thermal and solar control performance.
This helps maintain control of the environment

Guardian – RIBA accredited CPD’s
Over the past few years the development of
advanced architectural glass products have
improved dramatically. We are now able to
produce coated glasses which have a stabilizing
effect on the interior of a building, with optimal
thermal insulation, solar control and light
transmission. This has given way to a whole new
level of thinking on glass specification, allowing
glazed areas to flood buildings with light without
compromising the building efficiency.
This move towards greater areas of glass in
specifications has also been strictly controlled
by changes in legislation, standards and building
regulation, where a detailed understanding of
glass and glazing products is a necessity to ensure
the right product is specified to fulfil the right
requirement on any project.
Two help architects, designers and specifiers to
gain an depth knowledge into these important
areas Guardian have produced four CPD’s which
are a vital information aid to anyone specifying
glass into a building projects.
You can also gain more information on
our CPD’s and products by visiting
www.ribaproductselector.com and search
for Guardian Industries.
Our CPD seminars include:
1. The Production,
Technical Aspects
and use of Glass in
Architecture
2. Building Regulation
Document L and Energy
Efficient Glass
3. Glass as a Design
Material
Seminar
Half day glass works tour
and seminar
In 2010, Building Regulations
Document L was revised to
further drive the UK towards
energy conservation and reduce
CO2 emissions. This revision had
an almost profound affect on
glass specifications, laying new
guidelines on performances.
As familiar as we all are with
glass and its use in buildings, this
seminar takes a more innovative
approach, looking at different
applications and uses in building,
beyond the average perception
of glass specification.
This is an opportunity to
experience the size and scale
of float glass manufacture and
laminated glass production,
providing all the detailed
information required to specify
glass on any project.
The seminar is held in our
interactive glass room, where you
can test the physical attributes
of annealed, toughened and
laminated glass, as well as
coated thermal efficient and solar
control glasses, for yourself.
This seminar puts the effect of
Document L on glass specification
into context, providing detailed
information on performance
requirements and explains the
new parameters set for glass and
glazing specification.
Seminar
The seminar also takes a technical
approach, dealing with standards
and the regulations influencing
glass specification.
4. Coated Glass and
Energy Balance in
Buildings
Seminar
This seminar looks at the different
types of coated glass available
on the market. By evaluating
and explaining coated glass
performance, the seminar
demonstrates how the right glass
specification can reduce energy
consumption on your project,
through thermal insulation, solar
control, and providing high light
transmission. This helps to make
your project more environmentally
sound and sustainable. The
seminar also looks at the
Passivhaus glazing specification,
and finishes with a review
on achieving BREEAM points
through high performance glass
specification on projects.
The misconception around advanced high performance glass
There is a not so uncommon misconception that high performance glass, like our SunGuard ranges, are only used in
tall architectural towers and large buildings with curtain walling. However, this is far from the case. High performance
architectural glasses are being used in all kinds of projects from the Burj Khalifa to commercial shops and domestic
dwellings. Here are some key examples of projects where SunGuard advanced architectural glasses have been used
to reduce energy demands in buildings.
Tesco – Clay Cross,
Derbyshire
Tesco Extra at Clay Cross in Derbyshire is a key
example of a project that has used some of the
best advanced high performance glass, to help
regulate the temperature inside the shop, in a
scenario that most wouldn’t expect.
By using SunGuard High Selective SN 70/41,
the Tesco store is surrounded by natural looking
glass, with an exceptional level of performance,
rejecting 59% of all solar heat gains going into
the shop, as well as offering exceptional thermal
insulation and a very high light transmission
which ensures the store is well lit with
natural daylight.

Woodberry Park,
Hackney
To organise a CPD seminar or find out more information you can contact
us on: [email protected] or via telephone on 0800 032 6322.
Woodberry Park in Hackney is a rejuvenation area,
where old council housing tower blocks have been
knocked down and replaced with a new highly
specified mixed development, with exceptional
thermal insulation and stylish design. The area is
expecting to see over 300 new 1, 2 & 3 bedroom
apartments built by 2012/2013 of which 114 will
be dedicated to social housing with another 60
set aside for part ownership, the remainder will
be privately owned. These apartments have the
optimum level of energy efficient glazing used in
their windows, the SunGuard High Selective SN
70/41 glass used provides exceptional thermal
insulation to retain heat in the apartments. It also
greatly reduces cold spots and down drafts caused
by standard double glazing, which tend to make
rooms uncomfortable, especially in winter. The
SN 70/41 glass also offers excellent solar control,
reducing the chance of the apartments overheating
in summer due to excessive solar heat gains.
This advanced performance from the window
specification means that the energy costs will be
lower as the glass helps to maintain the temperature
inside the apartments, with less demand on heating
or air conditioning.
Seminars can take place either at your premises or in our interactive glass room (displayed below) located at our plant in Goole, East Yorkshire.

Poole High School, Dorset
A perfect example of smart architectural design
is Poole High School in Dorset, which was
designed and specified by Martin Hooper at
MCA Lawray Architectural practice (formerly
Lawray Partnership). Martin worked closely
with Poole County Council to ensure his design
met the demanding need for functionality and
desired aesthetic of the building, as well as the
strict performance requirements of the ‘Secure by
design’ standard and BREEAM.
By using our SunGuard High Selective SN
70/41, Martin was able to achieve a good neutral
appearance from the glazing on the building with
high levels of light transmission reducing the need
for artificial lighting during daylight hours. Martin’s
choice of glass also offers an optimum level of
thermal insulation with U values as low as
1.1 W/m2K. This reduces the demand on space
heating and solar control, ensuring low levels of
solar gain at just 41%, greatly limiting discomfort to
pupils at Poole High School, preventing overheating
behind the large glazed area’s specified.
www.guardian.com
The glazing for the building was fabricated by
Dual Seal, who in conjunction with Guardian
ensured exceptional lead times on all glazing.
This proved invaluable when a large pane was
accidentally broken near completion and a
replacement was supplied in days rather than
weeks, as quoted by some of the competition.
Dual Seal produced units to the highest standard
using toughened clear glass on the inner leaf
for safety inside the building, and laminated
SunGuard High Selective SN 70/41 on the outer
leaf, as specified to meet the requirements of
the “Secure by design” standard. This glazing
specification provided the complete package
of solar control, thermal insulation, high light
transmission, safety and security, with the added
advantage of lower energy consumption through
reduced running costs.

Lancashire Cricket Ground, Old Trafford
As part of the first phase of the
redevelopment, Old Trafford
Cricket ground has invested £12
million in a conference and events
centre called ‘The Point’. This
overlooks the cricket ground and
has the capacity to seat 1,000
guests and the flexibility to cater for
a wide range of events.
‘The Point’ has been carefully designed
by architects BDP and highly specified
with many environmental innovations.
This includes the Guardian SunGuard
High Selective SN 62/34 glass used to
help control the environment inside
the conference and events centre,
reducing the need for air conditioning
in summer and space heating in winter.
The main glazed front of The Point
faces south over the cricket ground,
providing optimum views, but creating
an architectural challenge due to
the vast amount of direct sunlight
experienced on the south face of any
building.
Additionally to this the architects had
the challenge of reducing the effect
of the southern exposure without
compromising the views over the
cricket ground with tinted solar
control glass.
The SunGuard High Selective SN 62/34
glass used was the ideal specification
to cater for this scenario, as it allows
an optimum light transmission of 62%
ensuring the views over the ground
are unspoilt. The glazing has a low
solar heat gain performance of 34%,
ensuring the area doesn’t overheat,

and an outside reflection of just 14%
greatly reducing reflective glare from
the south facing glazing, at players or
the supporters watching the game.
The light transmission of 62% also
greatly helps to reduce glare from
the sun inside the conference centre
viewing gallery. Additionally, the large
glazed areas are exceptionally well
insulated with optimum U values of 1.0
W/m2K, helping to keep space heating
cost down during winter months.

are likely to make the standard for domestic new

domestic housing will have to be designed and
constructed to fit the carbon neutral picture being
painted for our futures. Charlie Greig looked into
the future of sustainable housing and found a way
to achieve these eco and sustainable credentials,
in her ‘off the shelf housing’ project.
The Cub housing solution uses responsibly
sourced materials. The buildings are exceptionally
glazed façade. The right glazing specification was
imperative for Charlie to achieve the desired Code
5 of the Code for Sustainable Homes standard.
Our SunGuard HP Neutral 50/32 glass was
selected. This provides a slight reflective finish
which is visible during the day, allowing privacy
for the occupants, whilst maintaining a neutral
aesthetic appearance to ensure the views from
inside the Cub houses are unspoilt. At night,
the Cub houses use blackout curtains to provide
complete privacy.
“Designed and fabricated to run
on approximately £1 per week for
hot water, heating and ventilation”
airtight, way beyond current building regulation
standards, and are fitted with exhaust air
heat pumps for space heating, hot water and
ventilation. This, along with high levels of
insulation within the fabric of the building,
ensures that the Cub homes reduce CO2
emmisions through heat and energy conservation.
The Cub houses also use solar panels, and harvest
rainwater.
The glazing specification was carefully thought
out between Charlie Greig and our SunGuard
Architectural Sales manager Paul Anderson, who
looked at Charlie’s glazing requirements and found
the right glass specification to match the large
The SunGuard HP Neutral 50/32 glass has a high
visible light transmission to reduce the need
for artificial lighting during daylight hours, and
combined with the large glazed façade this delivers
an ideal light and spacious feeling of modern day
living. The low solar gain of 32% helps to ensure
the building doesn’t overheat. Careful selection
of not only the glass but the glazing configuration
ensures optimum levels of thermal insulation.
The combination of high performance glass and
argon filled cavity achieves excellent centre pane
U values of 1.1 W/m2K. The insulating glass
units also use our Guardian 6.4 laminated glass
(LamiGlass®), which helps to provide safety and
security to the large glazed areas. The laminated
PVB interlayer also removes 99% of UV rays
from sunlight passing through the glass, helping
to reduce the chance of furniture and fittings
inside the Cub houses discolouring due to direct
sunlight through the large glazed façade. The
laminated glass also improves the acoustic sound
control performance of the insulating glass units.
This combination of glazing specification and the
buildings fabric means the Cub houses achieve
sound reduction levels 4 x better than current
Building Regulation Standards. The Cub houses
are a modular based system, and are available
in one, three or five bed options, on one, two or
three floors. The Cub design meets a Code 5 –
under the Code for Sustainable Homes, and is
supplied already assembled to this standard. The
clever modular construction means that the Cub
houses are ready to live in within days of arriving
on site, making this a true ‘off the shelf housing’
solution. By supplying the houses in prefabricated
modules, they meet the tricky requirement of air
tightness that are necessary to achieve the Code 5
standard and ensure that the heat recovery system
functions correctly with minimal demands on
utilities for heating and air conditioning. In fact,
the Cub houses are designed and fabricated to
run on approximately £1 per week for hot water,
heating and ventilation. At £52 per year the Cub
homes truly fit the bill of housing for the future.

Our vast range of SunGuard products all have
specifically tailored performances to suit different
applications, building types and orientations. The
difficulty with such a range of glasses is finding the
best way to provide all the necessary information
on the products in a quick and efficient manner.
The obvious solution: www.sunguardglass.co.uk
SunGuardGlass.com was developed and launched
in 2008, designed specifically to cater for architects,
designers and specifiers so that they could gain
easy access to all the information to specify any of
our SunGuard glass products. The SunGuardGlass.
com website was so successful that in January 2009
it was chosen “Best on the Web” by the readers of
USGlass Magazine in the United States, which was
a prestigious accolade, introducing more architects
and designers to the new SunGuardGlass website.
We are now pleased to announce that
SunGuardGlass.com has branched off the website
allowing the UK to use the SunGuardGlass
framework to launch SunGuardGlass.co.uk.
This means that the SunGuardGlass.co.uk website
can specifically cater for the UK market, promoting
UK products without any danger of overlapping
with products designed for different climatic
regions and markets on other continents.
This also provides the perfect setting to present the
projects we have completed in SunGuard Glass in
the UK and establish easy links to the promotional
work and initiatives we run, developing awareness
for our products in the UK market within the
design community.
SunGuardGlass.co.uk also provides easy access
to our glass configurator, enabling anyone to
configure their insulating glass unit specification
and identify the performance of the glazing. With
the configurator now accessible online, it’s easier
than ever to ensure you always have the most up to
date version.

Guardian LamiGlass
The Guardian range of laminated glass is ideal for
architectural projects, comprising a huge range of
glass and pvb interlayer combinations which can
be sourced through our independent customers
in sizes all the way up to Jumbo sheets (3210mm
x 6000mm). Various types of interlayer may
be placed between the glass to impart different
qualities to the laminate; some introduce colour
for decoration or solar control, whilst others,
with a slightly different composition are specially
designed for reducing noise to acceptable levels.
Guardian also produce mixed glass (asymmetric)
laminates; mixing glass and interlayers of different
thickness to produce the optimum performance
for any project. Changes in the laminate
configuration may be used to enhance safety
and security, or to absorb specific frequencies of
sound, improving acoustic performance to suit
particular types of common environmental noise,
such as airplanes, railways, traffic noise pollution
or perhaps more localised noise from nearby pubs
and clubs on a busy city street.
LamiGlass Safety & Security
Our standard range of laminated glass products
is ideal for all safety and security applications.
All LamiGlass also cuts out approximately 99%
UV, helping to reduce the chance of furniture and
interior discolouration from direct sunlight.
Our standard thicknesses run from 6.4 all the way
up to 28.0. We can also produce bespoke options,
so please contact us to find out what laminate
combination is right for your project.
Guardian SatinDeco
By having both the 0.76 and 0.5 Sound Control
PVB options we can supply different sound
control glasses which reduce a far wider range of
frequencies. Sound control can also be achieved
up to RW 50 dB. Having this much flexibility
in sound control performance will help you to
ensure you specify the best glass to achieve even
the toughest acoustic requirements.

we also have a range of coloured PVB interlayers.
Our coloured range is ideal for added solar
control, privacy or decorative application.
Coated
Guardian SatinDeco is an acid etched glass with
a superior silky finish which allows it to be easily
cleaned, and often prevents unwanted finger
marks or dirt accumulating on the glass surface.
SatinDeco is an alternative to the more traditional
sandblast technique which is employed to
produce translucent glass. SatinDeco is produced
by dissolving a very thin layer of the glass
surface through acid erosion,
producing a smooth, perfectly
uniform finish, which
changes the transparent
characteristic of clear
float to a translucent
glass which disperses
light. The finished
glass produced under
this acid etching
technique leaves a far
less abrasive surface
to that produced by
sandblasting, which
effectively chips a fine
layer from the surface of the
glass, leaving microscopic peaks
and troughs which can be quite easily
marked as dirt and grease catches on the surface.
In contrast, the technique of acid etching leaves
a rounded almost bubble like surface seen at a
microscopic level, which is far less likely to mark,
as the surface has a far less abrasive finish to
catch dirt and grease on. The results speak for
themselves in the finished product, particularly
when the glass is being processed as it is far more
robust than sand blasted glass, ensuring higher
yields when the glass is manufactured.

The use of translucent glass has rapidly grown in
popularity over the last few years. The applications
where traditional pattern glass used to be used
for privacy, like building entrances and bathroom
windows, are now being replaced by translucent
glass, which offers a far more crisp, modern and
elegant finish, traditional pattern glass is increasingly
appearing dated. Consumers seem to now favour
acid etched glass as we have seen a definite shift in
sales over the past few years from pattern glass
to SatinDeco.
Applications
The applications for SatinDeco are far more wide
spread than most consider, when you think of
translucent glass.
Conservatories & Orangeries
One of the quickest growing applications is the
use of SatinDeco in conservatories and
orangeries, where SatinDeco is the
ideal product for privacy.
Bathroom Privacy
Offering improved
light transmission,
SatinDeco is
particularly ideal for
bathroom windows,
where privacy and
high levels of light
are a necessity.
Fittings and
Furniture
Other popular applications
are in furniture, interior
fittings like shelves and cabinets,
stairs, flooring, back lit wall cladding
or back lit counters.
Partitioning
Partitions
One of the most popular applications however,
is still partitioning. SatinDeco is both elegant
and functional regardless of the application
environment; looking equally at home in offices
or houses and apartments.
SatinDeco LamiGlass
SatinDeco can be laminated in all of the
LamiGlass options, which provides safety and
security in any application it is applied to.
SatinDeco LamiGlass can implement improved
sound control, and add a hint of colour to liven
up the interior of any design.
SatinDeco Mirror
To add dramatic affect to any design, SatinDeco
can be supplied mirrored. This creates an elegant
translucent affect which on closer inspection
reveals a reflection. SatinDeco Mirror creates the
illusion of increased space, and adds light and
depth to any interior design.
All SatinDeco products are available in sizes all the way up to Jumbo (3210mm x 6000mm) and in
thicknesses from 3-15mm. SatinDeco Mirror is available in thicknesses from 3-8mm.
Size & Availability
LamiGlass ranges can be supplied in thicknesses from 6.4 up to 28.0.
Other thickness and glass / interlayer combinations are available on request.
LamiGlass can be supplied in sizes up to Jumbo (3210 x 6000mm). LamiGlass
Coated can be supplied in thicknesses from 6.4 up to 16.8 and in sizes
up to Jumbo.

different colours, or we can supply other colours based on minimum order
quantities, please contact our sales office (0800 032 6322) for further information.
Royal Ascot, Main Grandstand
Royal Ascot grandstand uses over 3000 pieces of
cut, processed and finished glass internally and
externally, of which a variety of our LamiGlass
range featured in the project. To ensure views of
the race course within the Grandstand were not
obscured, LamiGlass was used to create protective
partitions and balustrades. Laminated glass was
also used for five stair cases, corporate boxes and
internal doors.
The initial multi-rail balustrade system designed
for the front of the grandstand, was replaced by
laminated glass when the designers realised that
some views of the race course were obscured by
the multi-rail system.
To provide privacy in keeping with the glass
specified already in the grandstand, privacy screens
were produced in 17.5mm thick white (opal/
diffuse) LamiGlass, providing safety, security and
improved acoustic performance, as well as privacy
from the opal/diffuse finish, which obscures the
glass without completely blocking light from
the area.
