ABSTRACT:
A tilt-in window assembly of the type wherein the sash is conventionally held only at the top and bottom between extruded window frame side rails, previously allowing the sash to be bowed inwardly by heavy wind forces. The extruded window frame is now provided at its side rails with protrusions extending for the entire height of the frame. The sash has side flanges which cooperate with the side rail protrusions to limit the inward bowing of the sash so as to prevent the sash weather-stripping from disengaging from its normal sealing contact surfaces, thereby preventing external air from passing by the weather-strippping.
