Fiberglass Windows

Why Choose Fiberglass Windows?

Fiberglass windows are strong and built to last. They’re beautiful in modern and 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.

Built to Last

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

Exceptionally Strong

If you want a wall of unobstructed views, fiberglass windows are your answer. They’re exceptionally strong and durable.

Low Maintenance

Upkeep on fiberglass windows is very minimal. The baked-on paint finish won’t peel or crack and protects against UV stains. Unlike wood, it won’t swell.

Custom Colour

Can’t quite find the colour you’re looking for? You’re in luck. Our fiberglass windows offer an upscale look with more custom and deeper colour options.

Designed for You

Express your creativity and increase your curb appeal with endless grid options. Create the window design that’s perfect for your home.

Superior Hardware
