Contractors and homeowners know that Typar® is the one for their housewrap needs. Typar HouseWrap, The HouseWrap That Survives, meets all codes requirements as a Type I air barrier and is ideal for both commercial and residential construction jobs. Typar HouseWrap is the one because it offers excellent water holdout, tear strength, air holdout, moisture vapor transmission, ultraviolet performance and surfactant resistance.
Typar HouseWrap performs on the job as well as in laboratory tests; its strength ensures a superior air holdout. Other housewraps can tear in the wind or from the rigors of the job site, and when they do, the housewrap is no longer an effective barrier. Used as a sheathing membrane to cover the cracks and gaps that are a normal part of any building, Typar HouseWrap helps prevent air penetration into the wall cavity that would affect the comfort and energy efficiency of the building. Typar HouseWrap is equivalent to 5/8-inch particleboard in stopping air leakage.
A microporous membrane, Typar HouseWrap offers an unsurpassed water holdout from rain. Designed to perform as a weather barrier that will prevent water intrusion, Typar may help protect your wall cavity from water damage.
A housewrap must also breathe to prevent moisture vapor from being trapped in the wall cavity. Typar HouseWrap's water holdout is balanced with an optimal perm rating of 13.9. This perm rating ensures that while water is prevented from entering the wall cavity, ideal levels of moisture vapor are allowed to escape.
Typar HouseWrap sets the standard for performance even when surfactants are present. Wood tannins, cedar oils, turpentine, as well as the soaps found in some stucco, can increase the wettability of a housewrap. Because these surfactants reduce the surface tension of the water and allow it to flow more easily through the pore structure of the housewrap, the sheathing is no longer protected from wind-driven rain and water damage. The superior surfactant resistance of Typar minimizes this "wetting" when in contact with these components, making it excellent for installation under wood siding and stucco.
For complete details on installation, refer to the Specification and Installation Guide.
