Wynna Foil
Wynna Double sided Aluminium foil is made from 2 outer layers of pure aluminium foil and 1 layer F/R Kraft paper. These layers are bonded together with F/R Glue and reinforced with 3-way fiberglass scrim. It is ideally used as sarking for roof and vapour barrier for HVAC insulation, in walls behind cladding or under timber floors, for residential and commercial building. Combined with glasswool / rockwool / mineral wool / foam insulation, it performs well as a vapor barrier and reflective foil insulation for air-conditioning ducts, pipes and vessels.
