DuPont Tyvek Housewrap Breather Membrane

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 microfibres bonded together to create a maze, Tyvek 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, Tyvek is resistant to UV damage and general wear and tear.
