Tyvek® breather membrane products for buildings offer proven, long-lasting protection against water and air infiltration and the effects of condensation. They also improve energy efficiency significantly.
AirGuard® air and vapour control layers help keep interiors cooler in summer, make roof and wall insulation more effective in winter, and significantly reduce convective heat loss. The bottom line: less condensation – and more comfort.
Tyvek® and AirGuard® membranes are BBA-approved for cold pitched roof construction. They minimise interstitial and surface condensation by allowing moisture to permeate up into the batten space, then out into the atmosphere.
DuPont™ Tyvek® breather membranes make an ideal secondary water barrier. Unlike building paper, they protect walls effectively from external moisture and condensation, while helping to improve thermal performance too.
