Waterproof Vapor Barrier Membrane For Walls

PRODUCT DESCRIPTION A high-performance reflective vapor-barrier membrane, thermally laminated from aluminum foil and a PET reinforcement grid. Delivering Class-0 vapor permeability, high solar reflectance, and superior puncture resistance, it provides a single-layer, dual-function shield against both moisture and heat for roofs and walls. PRODUCT APPLICATIONS • Underside of metal-roof insulation: stops indoor vapor drive. • Timber rafters beneath pitched tiles: pairs with breather membrane to create a dual-membrane system. • Interior face of precast concrete façade insulation: interrupts cold bridges and blocks inward vapor. • Curtain-wall cavities: combines thermal reflection with vapor control. • Cold-storage and passive-house envelopes: meets the most stringent air- and vapor-tightness requirements. PRODUCT ADVANTAGES • Vapor-tight: ≤0.001 g m⁻² day⁻¹—completely seals the moisture path. • Reflective: mirror finish returns up to 95 % of radiant heat, cutting summer heat gain and reta…
