Double sided reflective insulation as Radiant barriers and Reflective insulation work by reflecting radiant heat. D/S Reflective Aluminum foil Radiant barriers are installed outside the Glass wool, Rock wool, mineral wool, foam insulation materials.
A heavy duty, premium grade F/R Grade D/S Foil Insulation. Double sided reflective insulation 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 5x 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 glass-wool /rockwool/ mineral wool/ foam insulation, it is excellent as a vapor barrier and reflective aluminum foil insulation for air-conditioning ducts, pipes and vessels.
