Air Pollution and
Our Need to Reduce it
1
“Air pollution is bad for our health. It reduces human life expectancy by more than eight months on average and
by more than two years in the most polluted cities and regions. Member States must comply with EU air quality
standards quickly and reduce air pollutant emissions”.
- Janez Potočnik, EU Commissioner for the Environment
In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in
improved air quality across the region. However, air pollutant concentrations are still too high, and air quality
problems persist. A significant proportion of Europe’s population live in areas, especially cities, where air quality
standards are exceeded: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks.
Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants.
Reducing air pollution therefore remains important.
- European Environment Agency
City of London Air Quality Strategy 2011-2015
The Greater London Authority published a report in 2010, which detailed that an estimated 4,267 premature deaths
in London in 2008 could be attributed to long term exposure to fine particles (PM2.5). The City of London has some
of the worst air quality in the country. This is primarily due to the density of development and its geographical
location.
All local authorities in the United Kingdom are required to assess air quality and identify areas where it is unlikely to
meet objectives set by the Government. The objectives have been set at levels at which minimal effects on human
health are likely to occur. Air quality in the City does not meet the objectives for both annual average and hourly
average nitrogen dioxide, and daily average particulate matter (PM10). As a consequence, the City has been declared
an Air Quality Management Area for these two pollutants.
The City of London Air Quality Strategy focuses on action to reduce nitrogen dioxide and course and fine particles
(PM10 and PM2.5). The measures outlined, along with those in the Mayor‘s Air Quality Strategy, will improve air
quality in the City. However, the proposed action will not be sufficient to meet the Limit Value for nitrogen dioxide.
This requires coordinated national action.
Nitrogen Oxide (NOx)
Pollution
2
What is it?
Nitrogen dioxide is an irritant gas, which at high concentrations causes inflammation of the airways.
When nitrogen is released during fuel combustion it combines with oxygen atoms to create nitric oxide (NO). This
further combines with oxygen to create nitrogen dioxide (NO2). Nitric oxide is not considered to be hazardous to
health at typical ambient concentrations, but nitrogen dioxide can be. Nitrogen dioxide and nitric oxide are referred
to together as oxides of nitrogen (NOx).
NOx gases react to form smog and acid rain as well as being central to the formation of fine particles (PM) and
ground level ozone, both of which are associated with adverse health effects.
Sources of NOx Pollution
NOx is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high
temperatures. In areas of high motor vehicle traffic, such as in large cities, the amount of nitrogen oxides emitted
into the atmosphere as air pollution can be significant. NOx gases are formed whenever combustion occurs in the
presence of nitrogen – e.g. in car engines; they are also produced naturally by lightning.

Health issues created by NOx.
NOx mainly impacts on respiratory conditions causing inflammation of the airways at high levels. Long term
exposure can decrease lung function, increase the risk of respiratory conditions and increases the response to
allergens. NOx also contributes to the formation of fine particles (PM) and ground level ozone, both of which are
associated with adverse health effects.
The impact of nitrogen dioxide on ecosystems
High levels of NOx can have a negative effect on vegetation, including leaf damage and reduced growth. It can make
vegetation more susceptible to disease and frost damage. A study of the effect of nitrogen dioxide and ammonia
(NH3) on the habitat of Epping Forest has revealed that pollution is likely to be significantly influencing ecosystem
health in the forest. The study demonstrated that local traffic emissions contribute substantially to exceeding the
critical levels and critical loads in the area. The critical level for the protection of vegetation is 30 µg/m3 measured
as an annual average.
NOx also reacts with other pollutants in the presence of sunlight to form ozone which can damage vegetation at
high concentrations.
Notes:
Critical Level is the threshold level for the atmospheric concentration of a pollutant above which harmful direct effects can be shown on a habitat
or species. Critical Load is the threshold level for the deposition of a pollutant above which harmful indirect effects can be shown on a habitat or
species.
NOx Level Objectives
Twelve European Member States exceeded one or more of the emission limits set by the EU National Emission
Ceilings (NEC) Directive, according to recent official data for 2010 reported to the European Environment Agency
(EEA). In some instances the limits were exceeded by significant amounts. The pollutant for which most exceedances
were registered was NOx.
The European Union sets Limit Values for a range of pollutants that are considered to be harmful to health and the
environment. The European Commission can take action against any Member State if the air quality does not meet
the Limit Values throughout its territory.
At present there are two health based objectives that have been set for nitrogen dioxide. The first is to make sure
hourly concentrations do not go above 200 µg/m3 for more than 18 hours in any year. The second objective is to
ensure that the annual average is no greater than 40 µg/m3.
Air quality in many large cities in England and Wales does not meet the European annual average Limit Value for
nitrogen dioxide. In central London, air quality adjacent to some busy roads does not meet the hourly average Limit
Value for nitrogen dioxide.
All local authorities in England and Wales have a statutory duty to assess air quality. This is detailed in the
Environment Act 1995. If levels of pollution don‘t meet the objectives set by the Government, the area must be
declared an Air Quality Management Area and an action plan implemented to bring levels of pollution down.
According to the 'City of London Air Quality Strategy 2011-2015' objectives for nitrogen dioxide and PM10 in the
City are not being met. Therefore, The City has been designated an Air Quality Management Area for these two
pollutants.
Notes:
EU Limit values are legally binding EU parameters that must not be exceeded. Limit values are set for individual pollutants and are made up of a
concentration value, an averaging time over which it is to be measured, the number of exceedences allowed per year, if any, and a date by which it
must be achieved. Some pollutants have more than one limit value covering different endpoints or averaging times.

How Noxite
Reduces NOx Pollution
3
®
UV
NOx
NO3
The Noxite® process - from harmful NOx particles to clean air.
A Noxite® roofing membrane purifies harmful NOx particles effectively from the air.
At first glance, a Noxite® roofing membrane doesn’t look any different to the quality membranes you are used to
from Icopal - a strong and durable capsheet.
Removal of NOx
Noxite® roofing membranes are quite different from all the other products in Icopal’s range. The surface slates/
granules of the Noxite® membranes are coated with titanium dioxide which functions as a catalyst in the process
of changing the NOx particles into harmless levels of nitrates. The process is activated when ultraviolet radiation
from the sun hits the titanium dioxide particles, releasing energy for breaking down the NOx particles. Polluted air
passes over the Noxite® membrane where the NOx particles are converted into harmless levels of water, carbon
dioxide and nitrates, which are then washed away by the rain. It is that simple to clean the air, and the best part is
that the Noxite® effect lasts for the entire life of the roof.
This innovative roofing solution makes an enormous contribution to reducing air pollution by harmful NOx particles.
To quantify the effect: i. 1 m2 of Noxite® roofing membrane provides the amount of clean air that is breathed in by 12 people over a
year*.
ii. 100 m2 of Noxite® roofing membrane can purify as much NOx from the air as produced by an average car
travelling approx 10,000 miles per year.
iii. A Noxite® roof of 1,000 m2 purifies 52 million cubic metres of polluted air per year.
(* How the above is calculated: 1m2 Noxite® can purify 50,000 m3 per year. An average adult person breathes in 4,000 m3 air per year. Therefore:
50,000 / 4,000 = clean air for more than 12 people )
Investing in people and the environment
A Noxite® roof provides major opportunities for new-build projects or the renovation of existing premises to
reduce the effect of NOx pollution. It demonstrates a commitment to invest in people’s health and helps to meet
environmental objectives. A bonus is that this “green roofing” membrane does not incur any extra time or effort to
install or maintain. The only thing that needs to happen is to cover the roof of the project with a Noxite® membrane
and let the rest occur naturally. Using the sun, wind and rain, a Noxite® membrane roof converts polluting NOx into
harmless particles.
Proven performance
Studies carried out by the CNRS (Centre National de la Recherche Scientifique - French National Scientific Research
Centre) show a dramatic reduction in NOx levels attributed to the effect of the Noxite® membrane.
The image below summarises that when NOx gasses are pumped into an air chamber where the Noxite® membrane
and a UV light source are present, there is an 89% reduction in the NOx levels over a seven hour period. This
compares to only an 8% reduction over the same time period when a standard bitumen membrane is used.

Independent
Testing
4
The range of Noxite® membranes are part of Icopal’s Eco-Activ® portfolio of products, which contribute in a positive
way to the environment. Icopal believes in Noxite’s performance, and Icopal’s research suggests that a Noxite®
roofing membrane really produces cleaner air, which is better for people and the environment.
However, to confirm the performance of Noxite®, Icopal engaged the independent Dutch research institute, TNO,
to test the Noxite® roofing membrane for its air-purifying properties. TNO carried out the study with different
laboratory tests and pilot tests on roofs at Schiphol airport and in Utrecht.
The TNO laboratory tests demonstrated that a Noxite® roofing membrane breaks down harmful NOx particles. These
study results match Icopal’s findings and further research carried out by German and French institutes. During
outdoor testing it is more complicated to study the air-purifying properties of Noxite® because, understandably,
environmental factors such as sun, rain and wind, play a major role.
Icopal values TNO’s conclusions and therefore a comprehensive pilot was set up. Samples of roof drain water and
rainwater were collected from roofs at Schiphol and Utrecht and they were analysed for their nitrate concentration.
The difference in concentration between roof drain water and rainwater shows how many harmful NOx particles
were converted by the roof.
The results from the pilots match the results from the lab tests - Noxite® binds polluting NOx particles, breaks them
down and converts them into harmless nitrates.
Validation
5
In order to validate the results carried out on the Noxite® granules, used as part of the Eco-Activ® waterproofing
system, Icopal UK commissioned the British Board of Agrément (BBA) to assess the test reports complied by three
recognised independent testing bodies:
1.
UL Environmental Inc - Environmental Claims Validation for Paradiene 30 FR Eco-Activ®
2.
CSTB - Pass’Innovation 2009-016; Eco-Activ® waterproofing system
3.
TNO - The effectiveness of Icopal waterproofing membranes to capture nitrogen oxides.
Conclusion
Test results show that Noxite® granules have a significant depolluting capacity when added as a mineral finish to
waterproofing membranes.
A summary of the BBA's findings is as follows:
1.
UL Environmental estimated that, over a 20 year period, between 417 g and 4143 g
of nitrogen oxides per square metre of roof can be absorbed and degraded from the atmosphere.
2. The Centre Scientifique et Technique du Batiment (CSTB) reported a depolluting level of approximately 90% in
membranes two months after installation.
3.
TNO estimated an effective deposition rate of 0.08 cm.s-1 and 0.10 cm.s-1 as measured in laboratory tests and
in-use conditions respectively.

Interview with Frits Zandvoort (Head of R&D Icopal bv)
Noxite® is quite rightly one of Icopal’s biggest innovations of the past few years. The capsheet, topped with
titanium dioxide coated slates /granules convert harmful NOx into harmless nitrates that are washed off the roof
in rainwater events. It improves public health, and the environment, as the harmful pollutant is neutralised from
the environment.
Frits Zandvoort has been involved with developing Noxite® roofing membranes from day one. “The point when pilot
projects demonstrated that Noxite® really did work, was extremely convincing.” Frits Zandvoort is referring to the
pilot at Schiphol. The air around the airport is extremely polluted, which made the results easy to measure for the
Icopal researchers. “We are real pioneers with the development of Noxite®. The process from the idea to production
took three years. After that we also had our product tested independently. TNO came to the same conclusion we
did - Noxite® really works.”
“I hope as many companies as possible will use Noxite® for their roofing projects. Various studies have demonstrated
that it can make an essential difference to the air quality for humans and the environment. Each year, thousands
of people die from the consequences of NOx in the air - Often elderly people, small children or people with low
resistance. With Noxite® we can make a small contribution to reducing this.”, commented a concerned Frits
Zandvoort.
“Noxite® removes harmful NOx from the air and neutralises other harmful substances that cause smog. It works
particularly well on large surface areas.” However, it is important not to underestimate the contribution from
smaller premises. “We saw very good results on smaller scales too” emphasised Frits Zandvoort - Every little helps.
Companies that wish to construct or refurbish sustainably would do well to choose Noxite® for their flat roofing
projects. It enables governments and housing corporations to meet their environmental targets and make a major
difference to their own environment. Noxite® does not deal with the causes of pollution, but it provides a great
opportunity to reduce its harmful consequences. "Many companies really do their best to reduce the emissions of
pollutants, but the problem is too great to solve overnight. Doing nothing is not an option in our opinion. That’s why
we looked for a solution that reduces the damaging impact of NOx emissions", said Frits Zandvoort.

Noxite Case Study
William Harvey Hospital
Background
William Harvey Hospital is named after the English physician who
was the first to describe accurately how blood was pumped around
the body by the heart. A metal sheet roof over part of the clinical
zone at the hospital had failed and was in need of repair.
Project:
William Harvey Hospital
Location:
Ashford, Kent
System:
Noxite® Eco-activ® capsheet and
Total Torch System
Challenge
Client:
East Kent Hospitals University
NHS Foundation Trust
Specifier:
Neaves Perry Architects, Ashford
The roof had been overlaid around 20 years ago with an aluminium
sheet system, used to rectify a failing felted roof installed in the
1970s, but was unable to cope with the roof’s shallow pitch and
awkward detailing, and so a new solution was needed. Architect
Roger Neaves, of Neaves Perry Architects, required an aesthetically
viable roof covering that could be installed swiftly and would
provide a long-lasting, low maintenance finish. A flexible membrane
was to be specified to achieve a high quality finish with excellent
performance characteristics.
Main Contractor: Limen Construction Ltd, Rochester
Contractor:
Byford Roofing Services Ltd, Kent
Area:
1,500 m2
Completion:
May 2011
Solution
The cost and time efficiency of a membrane, over simply replacing the original standing seam roof, made this a
much more attractive specification option for the NHS Trust. Icopal’s innovative Noxite® membrane was chosen.
It includes a titanium dioxide coating specially designed to transform harmful nitrogen oxides into harmless nitrates.
To secure the contract, Byford Roofing had to reassure Hospital management that the new roofing material would deliver the
high performance required, but also show that it would be a highly cost effective solution with savings gained by using the
membrane verses replacing the metal roof.
Having won the contract, a team of up to five roofers working non-stop under a protective canopy completed the first phase of
the project in under six weeks. The torch–on membrane was quick to install, and the team achieved the highest level of detailing
around box gutters and edging, delivering a highly impressive finish.
The contract also marked the launch of Noxite® Eco-Activ® membrane into the UK, and so was a particularly significant achievement
for the Byford team.

Moorlands Junior School
Background
Moorlands Junior School in Sale was having a new extension added
to the existing building, but several problems with water penetrating
the existing roof which was causing constant internal damage.
Aedas, acting as Building Surveyor, and Seddon Construction as
the appointed Main Contractor, had several discussions and site
meetings with Icopal Limited to determine the best course of action
for the roof.

repaired at several points indicating areas that historically there had
been problems. When Icopal returned for a second visit, following
a number of dry days, core samples were taken which highlighted
areas of damp insulation. This indicated that the detailing, especially around the internal outlets, was the obvious cause of water
ingress. The works had to be carried out in the summer break and in co-ordination with the new build construction. Trafford
Council was insistent that the whole works be completed within the six weeks school break to avoid disruption to the operation
of the school. Roofing contractor, Mitie Tilley Roofing Ltd, informed the client that they would attempt to complete the works
in the allotted time but with a poor summer predicted, they anticipated that this would not be possible. It was also highlighted
during one of the site meetings that the school was registered with the Eco Schools campaign and so the building’s sustainability
was very important.
Solution
Icopal presented a full specification incorporating both existing and new roofs. Due to the severe ponding and the internal
outlet problems a tapered insulation scheme was proposed draining to the perimeter edge. The additional insulation would also
help improve the building’s energy efficiency. This would also be aided by the inclusion of new rooflights to meet the current
regulations. For the waterproofing element Icopal recommended the new, innovative Noxite® Eco-activ membrane, which was
enthusiastically accepted by the surveyor, main contractor and, more importantly, the client.
The Noxite® Classic membrane from Icopal is manufactured with recycled bitumen content with granular titanium dioxide finish
works actively with the surrounding environment to transform harmful nitrogen oxides into harmless nitrates.
Noxite Case Study
Holcombe Brook Primary School
Background
The school’s roof was very old and showing serious signs of ageing,
with blocked internal outlets causing severe ponding water on the
roof and splits in the covering causing several leaks. Several edge
details had disintegrated and were showing exposed rotting timbers
beneath the decks which were deteriorating due to exposure. All in
all the roof was in an incredibly poor state.
Problem
It became obvious to all parties that the whole roof had to be
stripped and replaced, including the deck. Given the extent and size
of the project the roof refurbishment had to be finished before the
new school year started in September. The client also wanted to
include new PV panels as energy conservation and environmental
considerations were important to the school.

Solution
The Headteacher authorised works to start before the end of term to ensure the September deadline was met, provided that the
works were phased to allow pupils to be relocated and areas to be cordened off during breaktimes.
For the waterproofing, Icopal put forward a specification of the Total Torch System capped with the depolluting Noxite® Eco-Activ®
mineral capsheet. Improved thermal efficiency was provided by increasing insulation thickness/ U-value performance.
The rooflights were replaced with modern, more thermally efficient units. This would increase the amount of natural light and
reduce the dependancy on internal lighting. New barrel skylights and additional rooflights were added to maximise the use of
natural light. Falls were improved and tapered insulation was installed to the valley gutter of the butterfly roofs to improve
drainage.
The school plans to add photovoltaic panels at a later date. Icopal's IcoSun Fix Console and weathering collars will be used to
provide mounting for the new PV panels without comprimising the wateproofing.
Both the Headteacher and Bury MBC were very happy with the project.
Following installation of the green technologies at Holcombe Brook members of the school's eco-council, represented
by pupils of the school, gave a presentation outlining the initiatives, which has helped the school to achieve
Eco-Schools' prestigious environmental Green Flag Award.
Noxite Case Study
Morden Mount Primary School
Background
The school had experienced many leaks over the years but six roofs
continually caused disruption to the school. At the request of the
school and Greenwich Borough Council, Capital Roofing was asked
to carry out a full survey of the roofs in question.
They identified some areas that required extensive alterations
and some asbestos removal to skylights and water tank glass
enclosures on two of the roofs.

Problem
Area:

The water-tank enclosures comprised vertical wired-glass panels
which served no real lighting purpose. The panels extended right
down to the existing roof covering meaning upstand detailing would
be problematic.
Completion:
September 2012
The School Head was also keen to use eco-friendly products when possible. With this in mind Capital Roofing asked Icopal to visit
site to provide a roof waterproofing specification, and to design a tapered insulation scheme
Solution
The overlay specification to the existing asphalt surface used Icopal's Profiles Vapour Vent XL vapour control layer, Thermazone
Torch-on insulation, and Profiles Vent XL underlay. The system was finished with Icopal's Eco-Activ® Noxite® Mineral Capsheet.
Tapered insulation was installed to 70% of the insulated roof area to increase thermal performance and provide positive falls for
efficient roof drainage. Due to the increase in height, kerb details were raised. The glass panels around the water tanks were
removed and replaced with a new PVC cladding, allowing the detail to be properly waterproofed.
Twenty-one skylights were replaced with new units, and new guttering was installed where required. Icopal's Elastoflex liquidapplied waterproofing system was used in small areas adjacent to the existing hall windows due to the type of vertical panels
originally installed. This allowed a better seal to be created to the panels, where membrane installation would have been tricky
to detail.
The School Head was absolutely delighted with the works and finish, and the project was carried out to programme and to budget.
Richard Perrett, Surveyor for Greenwich Council, commented ‘I was very impressed with the quality of workmanship carried out on
this project. Having read more about the Noxite® capsheet and having seen the appearance, I would not hesitate to recommend
this product on future projects’.

Other
Eco-Activ® Products
The Eco-Activ® range of products provided by Icopal include systems and components which provide a positive
impact on the environment.
Sustainability is paramount within Icopal and besides our Noxite® bituminous roofing membranes, we also supply
the following products to promote environmentally friendly roofing solutions.
Icosun FIX Console
The Icosun FIX Console is an innovative mounting
system to safely and securely fix solar panels onto flat
roofs. The system can be installed on to most Icopal
roofing systems with a bitumen, POCB or synthetic
waterproof capsheet. The benefit of the Icosun FIX
Console is its combination of strength and flexibility.
The mounting system is tailored to your requirements
and after simple installation, the system is fully
waterproof and is suited for any type of solar panel.
Icopal Green Roof Systems
The environmental benefits of green roofs are
numerous and well documented. They include:
• Storm water attenuation to reduce flood risk
• Urban cooling
• Improvement of air quality
• Provision of wildlife habitats
• Improved longevity of waterproof membranes
• Better aesthetics
Icopal provide a range of different green roof systems from extensive sedum and biodiverse to full intensive roof
gardens. Each system can be designed to meet the specific needs of the project.
Sun-Activ®
The Sun-Activ® membrane is a bituminous waterproofing cap sheet with a highly reflective, smooth
white surface. It is designed to comply with the Cool
Roof concept that gains more importance as the
demand for energy efficiency and environmental
awareness increases.
The Sun-Activ® membrane is especially beneficial for
use on new or refurbished roofs:
• With solar panel installations
• With a low amount of thermal insulation
• With a high amount of internal heat generation
• With air-cooling systems
These are mostly offices and public institutions such as schools and hospitals, residential buildings and industrial
premises.
A Cool Roof efficiently reflects sunlight and keeps its surface cool by re-radiating the sun’s heat back to its
surroundings. The roof temperature stays lower, therefore the amount of heat conducted into the building below
decreases.
Elastoflex
Elastoflex solvent free liquid waterproofing coating
is the latest product in Icopal’s range of liquid
waterproofing systems.
Elastoflex is an odour-free and solvent-free, fleece
reinforced liquid roofing and waterproofing system,
and is ideal for use on sustainability based projects
or on sensitive, occupied buildings where the odours
from solvent-based products would be disruptive.
Cool Roof Paint
Cool Roof Paint renovation coating is a water based
acrylic polymer binder that reflects the warmth of the
sun, so that the roof surface remains cooler and the
same applies to the space below. It prolongs the life
expectancy of the roof and the temperature inside
becomes more pleasant. Cool Roof Paint is solvent
free and weatherproof.
Therm'X
Therm’X is an innovative, insulating, high vapour
permeable pitched roof membrane with reflective
surfaces that helps improve internal building comfort
and performance whilst saving energy. Research
shows that Therm’X can provide a reduction of radiant
summer heat between 4-9oC therefore positively
contributing to maintaining internal building comfort
levels.
Therm’X is a high performing breather membrane
made from a highly reflective top breather membrane,
a polyester matt for complementary insulation and a
reinforced reflective underside which is mechanically
interlocked with the polyester matt.
The huge benefit of the Therm’X is the three-in-one product you get from it functioning as a traditional breather
membrane, with superior mechanical strength, a reflective outer surface to limit solar gain in summer and an inner
reflective side to increase U-value performance in winter.
Monarfloor® Acoustics
Icopal’s range of acoustic products encompasses
traditional floating floor treatments, (many of which
were developed by Icopal and are now universally
accepted as the industry standard), through to
innovative second generation systems specially
developed for use in the new build sector.
The Code for Sustainable Homes has been introduced
to drive a step change in sustainable home building
practice. It is a standard for key elements of design
and construction which affect the sustainability
of a new home and will become the single national
standard for sustainable homes.
The Code will be used by designers and builders as a guide to development and by home-buyers to assist in their
choice of home. All of Icopal’s advanced acoustics solutions can provide an opportunity to gain either three or four
Credits when used as part of a system. They can not only be cost-neutral but also provide opportunities for further
savings by, for example, allowing you to specify a continuous raft foundation between dwellings.
Dalite Rooflights
Natural light can dramatically improve the quality
of life for anyone living or working within a building
– boosting concentration, feelings of well-being and
productivity. Dalite Rooflights are an ideal way to
maximise the transmission of high quality, uniform,
natural daylight through a flat roof into the interior,
with all the benefits that daylight can deliver.
Incorporating rooflights into a flat roof can provide
three times more daylight than the same area of
vertical windows and provide a much more even
distribution of light.
Dalite Rooflights reduce energy costs and carbon footprint as well as promoting the health benefits of natural light.
Icopal and
Sustainability
10
A commitment to the environment
As a company, Icopal is proud of its strong environmental credentials, actively promoting the recycling of its
products whenever possible, in order to minimise the use of raw materials and energy in the development and
production of roofing and waterproofing solutions.
This means that many of our products meet – and often exceed – environmental standards, and are recognized by
many of the industry bodies promoting excellence in this field. As sustainable building practices become increasingly
mainstream, we are therefore ideally positioned to offer architects and developers the products they need both
to satisfy evolving environmental standards, and meet the increasingly informed expectations of building users.
Bitumen recycling
Unique in the world, Icopal have a recycling plant which can transform old /waste bitumen
membranes into the raw materials to create new high performance waterproofing membranes.
This process allows virtually endless recycling of bitumen roofing, protecting scarce resources
while delivering a high quality bituminous roofing product with all the benefits of the original
material.
By reusing the waste, considerable reductions are gained in the energy demand and CO2 emissions resulting from
the extraction, processing and transportation of raw materials, and as old roofs are no longer destined for landfill, it
further improves the sustainability of the entire production chain. For example, one tonne of collected and approved
bituminous roofing waste produces net savings on raw materials of 750 kg and CO2 savings of 615 kg CO2/tonne.
Grooves technology
Icopal’s high performance elastomeric torch-on capsheets feature a unique patented grooved profile that uses 25%
less gas and allows up to 30% faster application than traditional torch-on membranes.
Used in conjunction with specially formulated low-melt resin blends only a minimal heat application is required
to activate the unique adhesive properties of the membrane, as the heat is channelled quickly along the grooves
and disperses rapidly along the roll. This form of application ensures maximum adhesion with the minimum use
of energy, providing an instant 100% secure bond. It goes without saying that this also reduces CO2 emissions, is
better for the environment and produces cost savings for the roofing company.
