Water and Vapour Resistance

Tests by the British Board of Agrément confirm that Crown 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.

Crown Supafil Cavity Wall Insulation and offers virtually no resistance to water vapour, permitting the wall to breathe.

Environmental Performance

Crown 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.

They are free from HCFCs, CFCs and any other material with ozone depletion potential in their manufacture and content. They represent no known threat to our environment.

Crown glass mineral wool’s manufacture has a low impact on the environment and is classified as Zero ODP and Zero GWP.
