Abstract:
A laminated sill wrap assembly for providing an air infiltration barrier between and around the sill plate and foundation wall of a building under construction is disclosed. The sill wrap assembly comprises a batt of infiltration material laminated into a portion of a spunbonded or woven polyolefin sheet. The unlaminated portion of the sheet extends to form a single sealing flap. The flap is provided with an adhesive strip for attaching the flap to an outside wall surface of the building. In use, the laminated portion of the assembly is positioned snugly between the sill plate and foundation interface and the flap is wrapped upwardly around the sill plate and attached to the outside wall surface by the adhesive strip. Once in place, the assembly provides an air infiltration barrier between the inside and outside areas of the building.
