Fiberglass Windows

Strong, stable, and paintable—fiberglass is a premium choice for coastal and modern homes.

Fiberglass windows are made from glass fibers and resin, producing a frame that's incredibly strong yet lightweight. Because fiberglass expands and contracts at nearly the same rate as glass, these windows stay weathertight through temperature swings.

Fiberglass is dimensionally stable, resists warping, and can be painted—making it a favorite for coastal homes and slim-profile modern designs.
