Patent

CA 2227639

A self-sealing framing system is disclosed for curtainwalls, storefronts, and other framing systems for buildings in which frame members are erected in a grid and infill panels set within the openings of the grid. An elastomeric weathering gasket is mounted to a first frame member such that a portion of the weathering gasket overlies a recess formed in a side wall of the frame member. In an undeformed condition the elastomeric weathering gasket normally extends through a plane defined by the side wall of the first frame member. A second frame member oriented substantially perpendicular to the first frame member has an end abutting the side wall of the first frame member. The end of the second frame member contacts the elastomeric weathering gasket and displaces it onto one side of the plane by the contact with the end of the second frame member. A portion of the weathering gasket is displaced into the recess in the side wall of the first frame member. The weathering gasket thus forms a continuous seal between the first and second frame members along the line of contact with the second frame member.
