Why Choose Fiberglass Windows?

Fiberglass windows are strong and built to last. They’re beautiful in contemporary home design and won’t crack, peel, warp, split, pit, or corrode and are impervious to water. Fiberglass windows are more versatile today than ever before. They’ll stand up well through weather changes in the Okanagan.

Built to Last

Fiberglass expands and contracts at the same minimal rate as glass — even in the Okanagan’s changing seasons!
