CAVITYWALL Insulation uses Knauf Supafil® CarbonPlus, an unbonded, non-combustible glasswool insulation application designed for installation into existing and new cavity wall systems which significantly increases the thermal and acoustic performance of the wall.
Up to 35% of heat loss or gain in the home is through uninsulated cavity walls.
A double brick cavity without insulation is thermally rated traditionally at R0.6. With Supafil® CarbonPlus, a standard 50mm double brick cavity will improve wall system thermal rating to R1.9
According to the National House Energy Rating Scheme this can improve star rating by up to +1.2
This increase in thermal efficiency makes a home more sustainable; reducing power consumption needs and reducing the home’s carbon footprint.
 Based on Indicative Housing Energy Rating Software (HERS) Heating and Cooling loads for new and existing homes in NatHERS Climate Zone 13, single story cavity masonry, different orientations, R2 & R4 ceiling insulation.
 Based on testing completed by the manufacturer certified by Building Code Australia 30057.
