Fire Performance
Supafil Cavity Wall Insulation is classified as Euroclass A1 to
BS EN ISO 13501-1.
Moisture Resistance
Tests by the British Board of Agrément 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.
Thermal Performance
Supafil 40 Cavity Wall Insulation has
a thermal conductivity of 0.040 W/mK.
Supafil Green 37 Cavity Wall
Insulation has a thermal conductivity of 0.037 W/mK.
Fire Performance
Supafil Cavity Wall Insulation is classified as Euroclass A1
to
BS EN
ISO
13501-1
Vapour Resistivity
Supafil offers negligible resistance to the passage of water
vapour and has a vapour resistivity of 7.00 MN.s.g.m.
Environmental Performance
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's manufacture has a
low impact on the environment and is classified as Zero ODP and
Zero GWP.
