Fiberglass itself is nothing new. It’s been floating boats and adding strength to ladders for years. But until recently, the complex profiles required for window designs such as bay windows have been impossible to attain with fiberglass. Milgard’s R&D team faced this challenge and engineered a window and door system that’s impervious to water, cold, heat, insects, salt air and ultraviolet rays. The end result: efficient fiberglass windows and doors that maintain their beauty in every season, in any climate.
