Abstract:
1. A barrier assembly for sealing a building gap formed between a window frame and a rough opening of a building in which the window is received, the rough opening being defined by building framing members, the window frame being formed by respective pairs of inside and outside frame members which sandwich a pair of spaced apart glass panes forming the window therebetween, the respective pairs of inside and outside frame members together also defining a frame gap therebetween, the barrier assembly comprising: an adaptor carried by a first window frame member, 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 essentially transparent silicone rubber, the at least one membrane section defining a flexible sheet and a projection integral with the flexible sheet, the flexible sheet defining an inner membrane portion associated with the window frame and an outer membrane portion associated with the building framing members, the inner membrane portion being arranged at a generally right angle with respect to the outer membrane portion, the inner membrane portion and the outer membrane portion each being wide enough so that when the projection is received in the channel of the adaptor, the inner membrane portion spans the frame gap while the outer membrane portion spans the building gap, thereby providing an air and moisture-proof barrier between the window frame and the associated building framing member.
