Abstract:
1. A barrier assembly sealing the gap between the frame of a window and the rough opening defined in the exterior structural wall of a building in which the window is received, the rough opening being defined by building framing members, the barrier assembly comprising: an adaptor attached to the window frame, the adaptor defining a channel along at least a majority of the perimeter of the window frame, and a flexible sealing membrane providing an air and moisture barrier between the window frame and the building framing members, the flexible sealing membrane being formed from multiple membrane sections, at least one of the membrane sections being formed from an elastomeric material, the elastomeric membrane section defining a flexible sheet and a projection integral with the flexible sheet, the projection being received in the channel of the adaptor to provide an air and moisture-proof barrier between the window frame and the associated building framing member, the flexible sheet being wide enough to be sealed to the outside surface of the building's exterior structural wall without overfolding wherein the elastomeric material is butyl rubber, neoprene rubber, EPDM, or silicone rubber.
