Performance
Thermal
- Supafil™ Cavity Wall Insulation has a thermal conductivity
of 0.037 W/mK and 0.040 W/mK.
Fire
- Supafil™ Cavity Wall Insulation
is classified as Euroclass A1 to BS EN ISO 13501-1
Benefits
- Suitable for new-build or
retrofit
- Quick and clean to install
- Low Cost
- Injected after wall constructed,
allowing empty cavity to be checked beforeinstallation
- Made using recycled glass
bottles
- Silicone impregnated to prevent
moisture penetration
Certification
The BBA certificate in the United Kingdom for Supafil™ Cavity Wall
Insulation approves the product specification, application and
installation procedure for this product in severe exposure somes
and climate conditions. The certificate covers use in masonry
cavity walls with a minimum 50mm cavity width, up to 25m in
height, in any exposure zone. Supafil™ cavity wall
insulation has been successfully used for over 20 years and has a
proven track record in over 5 million homes across the world.
Environmental
Supafil™ Cavity Wall Insulation conserves energy and therefore
assists in reducing demand for fuels for the heating and
air-conditioning of buildings. As a result, they reduce the
emissions of the major greenhouse gas, CO2. The
energy and CO2 emissions saved by the products in
use vastly outweigh those generated in their manufacture. Supafil™
manufacture has a low impact on the environment and is
classified as Zero ODP and Zero GWP.
Moisture
resistance
- Tests and certification confirm that Supafil™ Cavity Wall
Insulation will not transmit water to the inner leaf. Nor
will they transmit moisture by capillary action across the cavity
or from below DPC level. This has been confirmed by independent
research conducted for the Energy Saving Trust, which shows that
cavity wall insulation does not add to the risk of water
penetration.
Vapour
resistivity
- Supafil™ offers negligible resistance to the passage of water
vapour and has a vapour resistivity of 7.00 MN.s.g.m.
Handling and
storage
- The packaging of Supafil™ Cavity Wall Insulation is designed
for short term protection only. For longer term protection on site
the products should either be stored indoors, or under cover and
off the ground.
