BondTape DFR-208B
D/S Reflective Aluminum Foil Insulation
Description & Application
A heavy duty, premium grade F/R Grade D/S Foil Insulation. It is made from 2 outer layers of pure aluminum foil and 2 layer F/R Kraft paper. These layers are bonded together with F/R Glue and reinforced with 2-way 5 x 5mm fiberglass scrim. It is ideally used as sarking and insulation under roofs, in walls behind cladding or under timber floors, for residential and commercial building. Combining with glasswool / rockwool / mineral wool / foam insulation, it is excellent as a vapor barrier and reflective aluminum foil insulation for air-conditioning ducts, pipes and vessels.
