Does Great Lakes Window fusion weld their frames and sashes?

The Grandview series window by Great Lakes Window has entirely fusion welded sashes and mainframes. This creates a solid, one-piece unit that maintains its strength over the years. Our state-of-the-art pinch fusion-welding process ensures frame and sash corners won’t have the excess variance found with other welding techniques. This process also insures a clean and natural look on our windows with optional woodgrain interiors.
