Casement & Awning Windows

Casement and awning windows have long been the preferred choice for homeowners who want the best combination of energy efficiency and ventilation. Unlike windows that slide up or sideways, casement and awning styles swing outward on a hinge and press their sash tightly against the frame when closed. This compression seal is why they consistently outperform other operable window types in airtightness — a factor that matters enormously when outside temperatures drop to -30°C or colder.

In Alberta, our winters are not just cold — they're persistently cold for months at a stretch, and the transition seasons bring dramatic temperature swings that can shift 30 degrees in a single day. These conditions place high demands on every window in your home. A window that seals tightly when shut isn't just about comfort; it directly affects your heating bills from October through April. Our casement and awning windows feature fusion-welded multi-chamber vinyl frames, low-E glass coating standard on every unit, argon gas fill between panes, and U-factors as low as 0.22 on triple-pane configurations — making them among the most thermally efficient windows available in Canada.

The difference between casement and awning styles comes down to hinge placement. Casement windows are hinged on one side, swinging outward left or right — ideal for capturing prevailing breezes when open. Awning windows are hinged at the top, opening from the bottom outward. This seemingly small distinction has a practical benefit: awning windows can remain open during light rain without allowing water inside, which makes them popular for kitchens, bathrooms, and any room where fresh air is welcome even on overcast days.

Both styles use a fold-away crank handle that operates smoothly and folds flat when not in use. The crank mechanism is particularly valuable above countertops, over sinks, or in other spots where reaching to push or slide a sash would be awkward. If you have windows in hard-to-reach locations — high on a wall, above cabinetry, or in a stairwell — casement and awning styles are often the only practical choice for operable ventilation.

Installation at Value Windows is handled entirely by our own crews, not subcontractors. We remove your old windows, properly flash and seal the rough opening, and install the new units to manufacturer specifications. Most single-window replacements take under two hours per opening. We clean up the work area fully before leaving. Our installations come with a lifetime warranty on the frame and seal, backed by our Edmonton-based team.

For basement egress compliance, casement windows are consistently the easiest type to meet Alberta Building Code requirements. They open fully to the full width of the sash, making the calculation of clear opening area straightforward. If you're finishing a basement or adding a legal bedroom suite, casement windows are worth discussing during your consultation.

Maintenance on casement and awning windows is minimal. The hinged design means you can clean the exterior glass from inside your home — simply open the sash and wipe both sides without ladders. The hardware is the main thing to watch: keep the crank mechanism lightly lubricated and inspect the weatherstripping annually. If you notice any drafts at the corners, our team can address this under warranty.
