Great Lakes Window, Inc.

Description

A 1978 research project concluded that in Europe approximately 65% of all replacement windows were manufactured from polyvinylchloride (PVC) extrusions. At that time the American market for windows made of PVC was less than 3%.Recognizing this opportunity, a five-person team launched a venture in 1981 to manufacture vinyl replacement windows out of a small warehouse in downtown Toledo, Ohio. Initially Great Lakes’ product line consisted of a double hung, a slider and a picture window, all of which were mechanically fastened and available only in white.Throughout the next five years, Great Lakes Window grew its capabilities and product line offerings with the addition of casement, bow and bay windows, and began using an innovative new manufacturing process in the industry known as pinch fusion welding. This technique creates a solid, one-piece unit that maintains its strength over the years and ensures that frame and sash corners won’t come apart over time. Unlike competitors’ vinyl windows, Great Lakes products do not contain staples, glue, or nails. This provides customers with better performing and longer lasting windows.
