Energy Efficient Windows: A Smart Investment for Ontario Homeowners
Discover how upgrading to energy efficient windows can reduce your heating bills and improve comfort in your GTA home.
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
