Milgard Fiberglass Windows
Exceptionally strong and low-maintenance fiberglass window and door frames from Milgard are ideal for any style and climate.
Advantages of Fiberglass Frames
Fiberglass window and door frames are essentially composed of glass fibers and resin, materials that expand and contract very little with temperature changes in the weather. Innovation has made it possible to design a fiberglass frame and fiberglass windows and patio doors are becoming more popular among homeowners for its beauty and long-lasting durability.
Andersen Composite windows
We developed a material that is stronger than vinyl, made of wood fiber and thermoplastic polymer that is fused together and is unique to Andersen. We call it Fibrex.
What Is Fibrex® Material?
A blend of 40 percent wood fiber by weight, mostly reclaimed from Andersen manufacturing processes, with 60 percent thermoplastic polymer by weight, some of which is also reclaimed. Blocks thermal transfer nearly 700 times better than aluminum to help reduce heating and cooling bills.
Our doors come in the same material.
