What Are Casement Windows?
Casement windows are hinged on one side and swing outward like a door, operated by a crank mechanism. They're one of the most popular window styles in Ottawa homes—and for good reason. When closed, the sash presses tightly against the frame, creating a compression seal that's superior to sliding windows.
Casement windows swing outward for full ventilation
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 Casement Windows
- Superior energy efficiency with compression seal design
- 100% of window area opens for ventilation
- Excellent for hard-to-reach locations (over sinks, counters)
- 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 Casement Windows
Casement windows work particularly well:
- Above kitchen sinks where you need reach without leaning
- In bathrooms for privacy and ventilation
- Bedrooms for fire safety egress (they open fully)
- Living areas where you want unobstructed views
- Any location where you want to catch a breeze
Crank Mechanism Repair
Window cranks wear out over time—the gears strip, handles break, or the mechanism becomes stiff. We stock replacement parts for most casement window brands and can often repair rather than replace the entire window. If your crank is giving you trouble, bring it in or schedule a service call.
