DFR-208B
Double sided reflective insulation is a type of insulation material that is designed to reduce heat transfer through radiation. It consists of a layer of reflective material, such as aluminum foil, sandwiched between two layers of insulation material, such as foam or bubble wrap.
Double sided reflective insulation is a heavy duty, premium grade F/R grade D/S foil insulation. Double sided reflective aluminum foil insulation Made from 1 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.
The aluminum foil layers reflect heat, helping to keep spaces cool in hot weather and retain warmth in cold weather. Double sided reflective insulation as radiant barriers can reduce energy loss costs 5% to 10%. It is lightweight and easy to handle, which can make installation simpler compared to heavier traditional insulation materials.
Double-sided reflective insulation can be used in a variety of applications, including walls, roofs, floors, and HVAC ducts. 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.
