Milgard Fiberglass Windows

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.

Ultra Series Fiberglass Windows
Ultra Series

Ultra, as the name implies, is the ultimate window frame material. Ultra fiberglass windows combine a traditional wood-frame profile with the strength, stability and zero maintenance of fiberglass. Our Ultra series withstands the harsher sides of Mother Nature like no other window, yet look like painted wood.


WoodClad Series Fiberglass Windows
WoodClad Series

Milgard WoodClad fiberglass windows satisfy both the architectural purist and the realist. You get a carefree fiberglass exterior, plus the beauty of a wood interior. And we do mean beauty. Our windows feature furniture-grade, clear, vertical-grain Douglas fir. Without a nail hole or staple on them.
