The Benefit of Natural Light
- Living in the north we all need more natural daylight in our homes, particularly during the winter months when days are shorter, there are fewer hours of sunlight, and the sun is at a lower angle than during the summer.
- Natural light has been proven to increase happiness and productivity.
- Increasing the amount of natural light in your home offsets the impact of Seasonal Affective Disorder, which affects many people in the winter when they do not receive enough sunlight.
- Natural light has been shown to lower the risk of nearsightedness in children and young adults by helping the eye produce dopamine, which aids in healthy eye development.
Self Flashing: the Easiest Skylight Model to Install
- Attractive low profile appearance – compliments your roof line.
- Self Flashing skylights are easy to install on any composition shingle or shake roof.
- The Columbia self flashing skylight is the choice of installers and do it yourselfers across the country because of the ease of installation with its integrated PVC vinyl interior frame and flange.
- No need to build a wood curb or flash, saving time and money.
Efficient ENERGY STAR® LoE3 Double or Triple Glazing with Argon Gas
- For maximum energy efficiency select from Columbia’s wide range of ENERGY STAR® LoE3 366 with advanced triple LoE3 coated glazing options – double and triple glazed. All options are available with laminated inner lite.
- The space between the glass panes is filled with argon gas, a natural, non toxic, high performance insulator.
- Because argon is denser than air it is superior at insulating your home than a conventional double pane skylight. It reduces cold or hot temperatures from transmitting through the glazing unit.

The benefits of Columbia’s laminated glass
Superior Sound Reduction
Reduces the effects of sound by up to 30% compared to standard double pane glass, and up to 50% less than a acrylic dome skylight.
Bring natural light in without additional noise such as traffic or planes.
Additional Security
Laminated glass is far harder to break and penetrate than traditional glass.
So, if you are concerned about security it is worth considering. The innermost interlayer holds the glass together in case of breakage.
Best in class UV Protection
Laminated glass lets the light in but protects your home from UV rays. The ideal choice to prevent fading of your floors, furniture and artwork.
We offer triple glazing on all models
Columbia is the only skylight manufacturer offering triple glazing (including laminated options) on all skylight models, fixed & venting, standard and custom sizes.

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.
