BARRIER ASSEMBLY FOR BUILDING OPENINGS

摘要

A barrier assembly for sealing the gap between the frame of a window and the rough opening (22) of a building in which the window is received comprises an adaptor (32) attached to the window frame and a sealing membrane (34) providing an air and moisture barrier between the window frame and the framing members (24, 26, 28, 30) defining the building's rough opening. The flexible sealing membrane (34) is formed from multiple membrane sections (70), at least one of which is formed from a flexible sheet (38) and a projection (46) integral with the flexible sheet (38), the projection (46) being received in a channel (36) defined by the adaptor (32) to provide an air and moisture-proof barrier seal between the window frame and the associated building framing members (24, 26, 28, 30).
