Aluminum Foil Insulation Description

 

Our double sided reflective insulation is a heavy-duty, premium-grade, flame-retardant (F/R) solution. This robust aluminum foil insulation is constructed from pure aluminum foil layers, reinforced with two layers of F/R Kraft paper, all bonded together with F/R glue and strengthened by a 2-way 5x5mm fiberglass scrim. The aluminum foil layers are highly effective at reflecting radiant heat, helping to keep interior spaces cooler in hot weather and retaining warmth in colder climates. Utilizing double sided reflective insulation as a radiant barrier can significantly reduce energy loss costs, potentially saving 5% to 10% on energy bills. Its lightweight and easy-to-handle nature also simplifies installation compared to traditional, heavier insulation materials.

Applications:

The versatility of double sided reflective insulation makes it suitable for a wide range of applications:

  • Building Envelopes: This 2 sided reflective insulation can be effectively used in walls, roofs, and under floors to enhance the thermal performance of residential and commercial buildings. It is ideally employed as sarking and insulation under roofs or in walls behind cladding.
  • HVAC Systems: When combined with materials like glass-wool, rockwool, mineral wool, or foam insulation, this aluminum foil insulation serves as an excellent vapor barrier and reflective insulator for air-conditioning ducts, pipes, and vessels, preventing condensation and improving system efficiency.
