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.
Tyvek® FireCurb™ breather membranes use patented technology that brings next-generation flame retardancy to high-rise buildings with ventilated facades – by self-extinguishing flames before they can spread.
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.
