Why Columbia

No Leaks No Flashing

Find Out Why Columbia Skylights Don’t Leak

Columbia’s Canadian made skylights are designed and manufactured with the finest quality materials, combined with over 5 decades of experience. We are proud to have supplied over 1 million skylights for North American roofs.

Our skylights don’t leak – the frame design is proven to repel the worst of Canadian weather, and we use high performance glazing from the leading North American glazing manufacturer Cardinal Glass Industries. Acrylic and polycarbonate are supplied by the highest quality North American producers. Our skylights combine a durable extruded aluminum exterior frame and a heavy duty PVC vinyl interior frame.

The Columbia 4 sided rigid condensation gutter has been designed with additional width to allow for maximum moisture control.

All our components are manufactured in North America by suppliers we have worked with for decades.


Canadian made skylights, designed for our harsh climate

Columbia skylights are specifically designed for life in our Canadian climate. Whether subjected to snow, ice, wind, hail, or intense heat, our products are engineered to outperform these demanding conditions.

Many imported skylights are designed for a more temperate climate and lack the performance and durability. Columbia has spent many decades manufacturing premium quality skylights that have stood up to the test of time in our Canadian climate.

Every aspect of the skylight has been studied, engineered, and tested.

Columbia utilizes the best materials available, including the latest glass technology.

Energy efficiency is a concern for Canadian homeowners because of our extreme climate. Columbia is the only Canadian manufacturer to offer Triple Glazing on all our skylight models, fixed and venting. We offer more ENERGY STAR® glass options than any other manufacturer.
