DuPont Tyvek Housewrap Breather Membrane 100m

DuPont Tyvek Housewrap is a high performance breather membrane that offers protection during construction and over the life of a building. Due to its unique high-quality polyethylene single functional layer which comprises millions of micro fibres bonded together to create a maze, Tyvec is impermeable to water and yet allows water vapour to pass through the natural pores in its structure. This makes the product naturally vapour-open and at the same time watertight. Due to its robust structure Tyvec is resistant to UV damage and general wear and tear. The unique vapour permeable properties keep the inside dry while protecting from outside water.
