AirGuard® Reflective is a 100% airtight vapour barrier membrane that has one aluminium side, which has very low emissivity and helps to considerably improve heat insulation in buildings. If this reflective membrane is correctly installed, the insulation will offer excellent protection against heat loss via radiation, convection and conduction. AirGuard® Reflective is used to prevent moist indoor air from infiltrating into insulation layers in wall and roof constructions. This helps to avoid condensation, and eventually mould, within the insulation material. The membrane offers excellent tear resistance and is easy to place.
