The DuPont™ Tyvek® range of breather membranes, Air & vapour control layers (AVCL’s) and accessories has been developed to provide protection to the building envelope. The products minimise air infiltration, resist to water penetration and reflect heat, whilst allowing moisture to migrate freely and safely into the atmosphere. They can be used for all kind of pitched roof constructions and for most forms of timber or metal frame walls as well as in new-build, refurbishment and extension projects.
