Windows are the weakest thermal link in any wall — a single pane of old glass insulates about as well as a sheet of cardboard. Upgrading to modern energy-efficient windows is the most direct way to cut an Alberta heating bill and fix cold, drafty rooms at the same time.
An efficient window is a system: Low-E coatings reflect heat back into the room, argon gas slows conduction between panes, warm-edge spacers stop the cold short-circuit at the glass perimeter, and multi-chamber frames insulate the border of the unit. We build all of it in-house and publish the ratings — U-factor and Energy Rating (ER) — on every quote, so you can compare apples to apples.
Look for the ENERGY STAR® certification mark for Canada's climate zones. Most of our double-pane packages qualify, and our triple-pane packages reach the ENERGY STAR® Most Efficient tier.
