Fresh Air Ventilation
- Improve the health of your home’s interior environment with the clarity and brightness of natural light and fresh air ventilation. Breathe in, and feel the revitalizing power of fresh air.

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.

Why Columbia
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.

We have relocated our eastern distribution warehouse to a newly constructed facility in Mississauga, Ontario. Columbia’s new distribution warehouse is larger and able to store a full range of ready to deliver Columbia, Slimlite, and FAKRO products.
