Energy-Efficient Windows & Doors for Saskatchewan Homes
In a climate where the temperature can swing 80 degrees from the peak of summer to the dead of winter, energy efficiency isn't a luxury, it's a necessity. If you have older, single or double-pane windows, you are likely losing up to 30% of your home's heat directly through the glass and drafty frames. That's heat you are paying for on every single SaskEnergy bill.
At Sask Windows & Doors, we don't sell "good enough" windows. Every window replacement and door replacement we perform utilizes products that are ENERGY STAR® certified for Climate Zone 3, the strictest energy rating in Canada, designed specifically for the extreme cold of the Prairies.

The Anatomy of an Energy-Efficient Window
What makes a window truly energy-efficient? It's a combination of advanced technologies working together to stop the transfer of heat. It starts with the frame: our premium vinyl frames feature multiple hollow air chambers that act as a thermal break, preventing the freezing outside air from conducting through the material.
Next is the glass package. We highly recommend triple-pane glass for Saskatchewan homes. Between these panes, we pump in dense, invisible Argon gas. Because Argon is heavier than standard air, it drastically slows the movement of thermal energy. Finally, non-conductive "warm-edge spacers" are used to separate the panes of glass, completely eliminating the cold edges and condensation common in older windows that used aluminum spacers.
The Magic of Low-E Coatings
Winter Heat Retention
Low-E (Low-Emissivity) is a microscopic metallic coating on the glass that acts like a mirror to thermal heat. In the winter, it reflects your furnace's heat back into the room.
Summer Cooling
In the summer, the same Low-E coating reflects the sun's scorching radiant heat away from your home, keeping your air conditioning bills down.
UV Protection
Low-E coatings block harmful ultraviolet (UV) rays, protecting your hardwood floors, carpets, and furniture from fading in the harsh Prairie sun.
Understanding ENERGY STAR® Climate Zone 3
Canada is divided into different climate zones for energy efficiency ratings. A window rated for Vancouver (Zone 1) will fail miserably in Saskatchewan (Zone 3). When you buy from national chains, you must be careful to check the specific Zone rating of the window you are buying. At Sask Windows & Doors, every single product we install is certified for Zone 3. We don't sell anything less.
Government Rebates and Incentives
Because upgrading to highly efficient windows and doors significantly reduces your home's carbon footprint, there are often federal and provincial grants and rebate programs available to Saskatchewan homeowners. These programs can offset a significant portion of your upgrade costs.
We stay up-to-date on all current rebate programs. During your free consultation, we will advise you on which programs you may qualify for, ensure the products you select meet the strict eligibility criteria, and provide all the necessary documentation you need for your application.
