DuPont Weathermate Plus Housewrap is a non-woven, non-perforated polyolefin-based wrap designed for enhanced job-site durability and long-term product performance for builders who want superior protection against the elements. Weathermate Plus Housewrap is specially engineered to maximize a home's weather defense between the cladding and wall assembly, helping to ensure years of comfort for homeowners. Weathermate Plus Housewrap forms a continuous protective membrane that defends walls from damaging bulk water and air infiltration, safeguarding against costly energy loss. It reduces drafts - increasing home comfort - and features superior water resistance to reduce the potential for water infiltration that may lead to mold and water damage of underlying water-sensitive wood sheathing. The engineered water vapor permeability of Weathermate Plus Housewrap enables water vapor behind the housewrap to escape to the exterior, thereby helping the wall dry from the inside out.
