Why Energy-Efficient Windows Matter in Ontario

Ontario winters are severe, with temperatures regularly dropping well below -30°C. Energy-efficient windows with triple-pane glass and quality frame materials provide dramatically better insulation than older single or double-pane windows — translating directly into lower heating bills and a more comfortable home throughout Ontario's long winter season.

What to Look For

• Energy Star certification for the Canadian climate zone
• Low-E glass coatings to reduce heat loss
• Argon or krypton gas fills between panes for extra insulation
• Quality frame materials that won't warp or crack in cold temperatures
• Professional installation – even the best window performs poorly if improperly installed
