Envirotuff V Foil WF402AE is a radiant barrier designed to effectively reflect radiant heat through its low-emittance, double reflective surfaces. Ideal for extreme environments, this radiant barrier offers enhanced heat insulation performance with both sides featuring high-reflective coatings and extra protection through Low-E Coating Technology. This 5-layer fire-retardant compliant composite structure is made from double-sided reflective materials (aluminium and anti-corrosion Low-E aluminium surface), bonded to a reinforced, specially formulated high-density polyethylene woven fabric using a specialized fire-retardant adhesive, ensuring excellent durability, safety, and thermal efficiency.
