Envirotuff V Foil WF302A is a radiant barrier designed to effectively reflect radiant heat, through its low-emittance, double-sided reflective aluminium foil surfaces. This 5-layer fire-retardant compliant composite is constructed by bonding the reflective materials to a reinforced high-density polyethylene woven fabric using a specialized fire-resistant adhesive, ensuring excellent durability, safety, and thermal efficiency.
