ENERGY STAR certified windows can cut heating and cooling loss significantly — pair them with available rebates where you qualify. Browse all guides →
What ENERGY STAR means for your home
ENERGY STAR certified windows meet strict U-factor and solar heat gain standards for Canada. In Mississauga's climate zone, that usually means better comfort at the glass and lower HVAC run time.
Look for the label on the whole unit (frame + glass), not glass alone. Installation quality still matters — even top-rated units underperform if gaps are left around the frame.
