Fiberglass replacement windows.

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.

Replacement fiberglass windows from Milgard

Milgard gives you two distinctive choices when it comes to fiberglass windows and doors: Ultra™ and WoodClad™. When you look at a Milgard Ultra series, you might think that it's painted wood. Or in the case of our WoodClad series, you might even think it's made out of solid Douglas fir.

The truth is, our fiberglass windows give you the beauty of a wood window and the durability of a fiberglass frame. Make no mistake, our fiberglass windows will not crack, peel, warp, or stick. A statement no wood window manufacturer can make.
