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.

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.
New Mississauga distribution warehouse to better serve Ontario, Quebec & the Maritimes
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.
