Abstract

An impact resistant tilt window assembly includes a window frame with side jambs that have legs that extend in the direction of the exterior of the frame, an upper sash, a lower sash that moves vertically and tilts inwardly and tilt latch assemblies that are positioned on the lower sash, each tilt latch assembly includes a latch bolt with a nose end that includes a notch that is sized to engage the associated jamb leg when the lower sash is in a vertical orientation. The notch has an interior leg that moves along an interior side of the jamb leg and an exterior leg that extends behind an exterior side of the jamb leg and moves along the jamb leg when the sash moves vertically. The window assembly may further include U-shaped reinforcing inserts that are positioned within the jambs such that the tilt latch assemblies engage the inserts when the lower sash is in the closed position.
