Tyvek Airguard Reflective is strong 100% airtight vapour barrier is specially designed to give maximum thermal performance. Recommended for use with Tyvek® Reflex products, AirGuard® Reflective provides a good way to improve U-values in buildings. A highly vapour and water-resistant low emissivity internal vapour barrier, it considerably reduces interstitial condensation as well as improves thermal efficiency by reflecting up to 95% of radiant heat.FeatureBenefitWater vapour transmission (sd) 2000mConsiderably reduces risk of condensation into the insulationReflective surfaceConsiderably reduces convective heat lossesSuperior mechanical strengthDurabilityBBA-ApprovedLength: 50m.
