Abstract
A window frame provided with a tapered sub-sill that is mounted on the wall and via a plurality of spaced spacers tapered in the opposite direction to support the main frame sill element in its substantially horizontal position. The use of the tapered sub-sill and tapered spacers permit the sealing membrane positioned between the wall structure and the wall facing to pass therebetween and provide a good seal and provide a solid base for the main sill. In the preferred arrangement, a snap in seal is connected to the outside bottom edge of the sill and forms a seal between the facing layer and the sill and provides a projecting flashing to redirect rain.
Claims13
A window frame comprising a sub-sill having a mounting surface for positioning in a window opening in a wall and a sloping surface extending in an acute angle from the side of the sub-sill that faces outward relative to the window opening when the sub-sill is mounted in the window opening, a plurality of discreet spacer elements overlie said sub-sill and are positioned in axially spaced relationship relative to a longitudinal axis of the sub-sill, a main sill having a main mounting surface, cooperating fastening elements on said main mounting surface and said spacers for connecting each said spacer to said main sill and positioning said main sill substantially parallel to said mounting surface and means for connecting said main sill to said sub-sill,
- wherein said window frame further comprises a compression gasket, said compression gasket having a rib at one end and a deflectable element at its opposite end, a groove in said main sill in which said rib is received when said gasket is mounted on said main sill and an undercut on said main sill into which said deflectable element is snapped over when said gasket is mounted on said main sill.
A wall structure having an air space positioned between a structural wall portion and a facing wall portion, a window opening in said wall structure, a window frame including a sub-sill having a mounting surface and a sloping support surface extending at an acute angle from said mounting surface, said sub-sill mounted on said structural wall portion with said support surface sloping upward and inward relative to said window opening, a sealing membrane extending in said air space and positioned against said structural wall portion and passing over said sloping face of said sub-sill to provide a seal for said structural wall portion, a plurality of spaced tapered spacer elements positioned in overlying relationship to said sloping support surface and said membrane and extending up said sloping support surface, cooperating fastening elements connecting each of said spacer members to a main sill member and a connector connecting said main sill member to said sub-sill member.
