Improvements in seals for windows and other framed closures

摘要

A sealing strip (1) is disclosed which comprises a retaining web (2) adapted to be secured into a slot (14) in a frame member, which retaining web (2) is sealingly attached to an elongate sealing lip (6) formed so as to give rise to no more than a small sprue on welding thereof. A closure frame incorporating an extruded closure frame member (10) having an elongate slot (14) retaining such a sealing strip (1) is also disclosed. Such sealing strip (1) may comprise a flanged retaining web (2) which is inserted into the slot (14) in the frame member (10) with its flanges (4,5) overlapping the face of the frame member (10) to either side of the slot (14). The sealing strip (1) may be inserted into the frame slot (14) before the frame member (10) is cut to length and welded. <IMAGE>
