Abstract: A window sash frame which has fiberglass reinforced plastic framing members. The framing members have associated subframes. The subframes are joined at their ends so that the ends of the framing members are drawn towards each other to form a window sash frame having tight fitting corner joints. An associated method is also disclosed.

Abstract: A toggle tilt latch for a tiltable window assembly which comprises a base adapted to be mounted to a window sash, a handle pivotally mounted to the base and a plunger operatively associated and movable with the handle. The plunger has a free end which protrudes from the base and engages the window frame when the window sash is in its normal vertical position. The plunger is retracted into the base by rotating the handle away from the base. This will allow the window sash to tilt inwardly relative to the window frame. The handle portion not only gives a ready visual indication of whether the plunger is retracted or not but also can be used as hand holds by a user to facilitate tilting of the window sash relative to the window frame.
