Abstract: A window system comprises a frame having a top, a bottom and two sides, at least one slidable and tiltable sash disposed within the frame, and a locking device attached to each side of the sash. The locking device is pivotable between an unlocked position to permit tilting of the sash, and a locked position which locks the sash to the frame. In the locked position, the locking device prevents any air from infiltrating between the sides of the sash and the frame.

Abstract: A storm resistant device for a window that has a window frame enclosing at least one sash slidingly and pivotally mounted therein. The sash has side rails and the frame has vertical jambs that engage the side rails of the sash to raise and lower and pivot the sash. The storm resistant device comprises a first elongated bracket having a substantially Z-shaped cross section with two end segments and a middle segment connecting the two end segments. The middle segment is connectable to the side rails of the sashes with one of the end segments extending outward from the sash toward an adjacent jamb. There is a second elongated bracket having a substantially L-shaped cross section with two legs, one leg of the bracket adapted to be mounted to the jamb with a second leg of the L extending toward an adjacent side rail of the sash.
