Energy Efficient Windows: A Smart Investment for Ontario Homeowners

Why Window Upgrades Matter in Ontario

With Ontario's extreme temperature swings—from -20°C winters to +35°C summers—your windows play a crucial role in home comfort and energy efficiency. Old, inefficient windows can account for up to 25% of your home's heat loss.

Understanding Window Ratings

Energy Star Certification Look for windows certified for Climate Zone 3 (which includes the GTA). These meet strict criteria for:

U-Factor (heat loss rate) - lower is better
Solar Heat Gain Coefficient (SHGC)
Air leakage ratings

The Importance of Triple-Pane In our climate, we strongly recommend triple-pane windows. The additional pane provides:

Better insulation (R-value of 5-7 vs 2-3 for double-pane)
Reduced condensation
Better sound insulation
Longer lifespan
