<p>Housewrap (10) for attachment to a building (12) after installation of sheathing (14) and prior to installation of siding/cladding. The housewrap comprises a barrier layer (20) and an adhesive layer (22). The barrier layer (20) has a first surface (24), which faces inward relative to the building (12), and a second surface (26), which faces outward relative to the building (12). The adhesive layer (22) is applied to the first surface (24) for attachment of the housewrap (10) to the sheathing (14). The barrier layer (20) provides a moisture barrier against outside water or moisture, yet allows a water vapor transmission rate of at least 100 g/m<2>/day from the interior of the building (12). The adhesive layer (22) comprises a pressure sensitive adhesive that has a high moisture vapor transmission rate of at least about 100 g/m<2>/day.</p> |
