The best windows for Ottawa have ER ratings of 40+. Key performance specifications for Ottawa windows: U-factor of 1.2 or lower (low...
Casement windows (crank-open) provide the best air sealing and ventilation in Ottawa. The sash presses against the frame when closed, creating a tighter seal than sliding mechanisms. They're ideal for bedrooms, living rooms, and kitchens. Cost: $450-$1,200 per window installed.

Ask each installer: what brand of windows they install (and the specific product line), whether they do full-frame or retrofit installation, what their warranty covers (product and labour separately), how long they've been in business, and for references from recent Ottawa installations. Warranty comparison is critical. Look...

Yes, triple-pane windows are worth the 15-25% premium in Ottawa's climate. They significantly reduce heat loss, eliminate cold drafts near windows, reduce condensation, and lower heating costs by 10-15% compared to double-pane.
Quality vinyl windows last 25-35 years, wood windows 30-40+ years with maintenance, fiberglass 30-40 years, and aluminum 20-30 years. Sealed glass units typically need replacement after 15-25 years when seals fail and fogging occurs.
