Abstract
A glass channel insert to guide, support, and seal a slidable window in a supporting channel window frame. The channel insert includes a centrally disposed durable plastic strip to bear the weight of the window and side sealing or glide members, preferably a laterally disposed pair of opposed pile weatherstrips to seal the inner and outer window surfaces from wind and water. The bearing strip and the weatherstrips are adhered to a common surface of a flexible backing web, preferably by simultaneous ultrasonic welding, providing a substantially planar glass channel element which can be wound as a roll. In installation, the planar element is folded longitudinally to form a U-shaped glass channel insert, which can be sliced transversely at intervals along its back side to permit bending of the insert to follow the curved edges of windows.
