Patent

CA 2045653

A sash window is formed from a frame profile (20) and a sealed window unit comprising a pair of spaced parallel glass panels (10, 13). The frame profile includes a channel section with a transverse web (22) and upstanding side walls (23, 24) which are formed in- tegrally without separate stops and integrally with a sup- port element (21) for the window frame. The frame pro- file (20) is manufactured by pultrusion to provide a coef- ficient of expansion very close to that of glass. The sealed window unit is sealed to the window frame by a bead (32) of sealant material only at the corner between the inner face of the window unit and the transverse web supporting the side edge of the window unit. The sealant is thus protected from exposure to the elements. A drain- age opening (28) is provided in the web to allow the es- cape of moisture passing between the direct contact be- tween the outer side wall and the outer face of the win- dow unit.
