Easily installed prior to the building's exterior facade, DuPont Tyvek CommercialWrap is a tough, spunbonded polyethylene membrane with microscopic pores. It helps protect against bulk air and water infiltration, avoiding costly damage and reducing energy costs. Its vapor permeability allows harmful moisture vapor to escape from the wall cavity. This building wrap also offers added durability through tear-strength and the ability to withstand UV exposure for up to 270 days.
