Short answer: buy Energy Star certified vinyl windows for Canada’s climate zone, choose casement or awning windows for the tightest seal, add Low-E argon glass as a minimum, and consider triple-pane on north-facing and street-facing walls for comfort and noise.
Style: casement vs slider vs hung
Casement windows crank open and seal with a multi-point lock — the most airtight option. Sliders and single/double-hung windows cost less and suit rentals and bungalows. Bay, bow and picture windows add light and value to living rooms.
Glass: double vs triple pane
Double-pane Low-E argon meets the standard. Triple-pane adds roughly 20–30% better insulation and noticeably less noise — worth it near busy roads and in bedrooms.
Rebates
Federal and provincial energy programs change frequently. Energy Star certified windows are typically eligible when they are available; ask us at quote time and we will point you to current programs and the paperwork.
Installation matters most
The best window leaks if it is installed badly. Our installers remove the old unit, insulate the gap with low-expansion foam, flash the opening and cap the exterior. Select your windows on the Home Windows flyer and ask for a price with installation.
