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.

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.

Handling and Storage

The packaging of Knauf Insulation 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.
