Milgard Ultra Fiberglass Windows

Fiberglass windows are extremely strong, require low maintenance, and are known for their durability. Fiberglass material is made from glass fibers and resin, materials with minimal expansion and contraction as the temperature changes. Because the fiberglass frame is made from glass the window and the frame expand and contract together reducing swelling and warping.

Fiberglass windows are stronger and requires less less maintenance than wood windows or vinyl windows.
