DuPont™ AirGuard® Reflective is a low emissivity internal vapour barrier that combined with an air gap can enhance thermal comfort by reflecting up to 95% of radiant heat back into the building. Considerably reduces risk of condensation into the insulation Considerably reduces convective heat losses Sturdy barrier due to its superior mechanical strength Reaction to Fire: Class E* CE-conformity for plastic and rubber vapour control layer (EN 13984) BBA certificates: 08/4548 and 90/2548
