What Are Awning Windows?
Awning windows are hinged at the top and swing outward from the bottom, creating an awning-like effect. This design lets you ventilate your home even during light rain—the open sash acts as a shield, directing water away from the opening. Like casement windows, they use a compression seal for excellent energy efficiency.
Awning windows provide ventilation even in light rain
This design makes casement windows exceptionally energy-efficient—a real advantage when Ottawa winters hit -25°C and you're trying to keep heating costs down. The full opening also provides 100% ventilation, compared to just 50% for sliding windows.
Benefits of Awning Windows
- Ventilate during rain—water runs off the open sash
- Excellent energy efficiency with compression seal
- Great for basements and high wall placements
- Unobstructed views with no center rail
- Enhanced security—difficult to force open from outside
- Easy to clean from inside the home
- Works well with screens (screens mount on inside)
Ideal Locations for Awning Windows
Awning windows work particularly well:
- Basements where ventilation is needed but security matters
- Bathrooms for privacy and moisture control
- Above kitchen counters for rain-protected ventilation
- Combined with picture windows for added ventilation
- High on walls where other window types are impractical
Operator Repair
Awning window operators work hard over the years and eventually need service. Gears strip, arms bend, and hinges loosen. We stock replacement parts for most awning window brands and can often repair rather than replace. If your awning window is hard to open or won't stay closed, give us a call.
Installation & Replacement
Whether you're replacing old awning windows with modern energy-efficient units, upgrading to triple-pane glass, or installing casement windows in a renovation, our team handles the complete process. We'll measure precisely, order windows sized to your openings, and install them with proper insulation and weathersealing.
