Abstract
Wind resistance of a window mounting tilt sash between a pair of jamb liners is increased by braces that attach to frame sides of the jamb liners at the check rail region of the window. The braces have a profile that fits a frame side profile of the jamb liners, including brace channels that receive and support shoe channels of the jamb liners. The braces help the jamb liners resist deformation in response to wind force and significantly increase the wind resistance of the window.
