Supafil 34 Cavity Wall Insulation is an unbonded, non-combustible virgin mineral wool insulation which requires no mixing on site.
Supafil 34 Cavity Wall Insulation conserves energy and therefore assists in reducing demand for fuels for the heating and air-conditioning of buildings. As a result, it reduces the emissions of the major greenhouse gas, CO2. The energy and CO2 emissions saved by the product in use vastly outweighs those generated in it’s manufacture.
- Glass Mineral Wool has an A+ rating in the BRE Green Guide to Specification
- Zero ODP
- Zero GWP
- Manufactured using recycled glass
- Compression packed to reduce vehicle movements and fuel related CO2 emissions
Tests by the British Board of Agrément confirm that Supafil 34 Cavity Wall Insulation will not transmit water to the inner leaf. Nor will it transmit moisture by capillary action across the cavity or from below damp proof course 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 resistance - resistivity
Supafil 34 offers negligible resistance to the passage of water vapour and has a vapour resistivity of 7.00 MN.s.g.m.
Handling and storage
Supafil 34 is supplied in polythene packs which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground and should not be left permanently exposed to the elements.
