The stylish awning window resembles a casement but hinges at the top and opens outward.

Awning windows are available in both Ultraslim and Classic series, each featuring distinct frame profiles to suit different architectural and performance requirements.

Available in both double and triple glaze.

Awning Windows

An awning window is hinged at the top and opens outward from the bottom, like a canopy over the opening. The push-out or crank-driven sash seals under full perimeter compression when closed, and because the glass tilts outward when open, it deflects rain away from the opening rather than letting it in. Window Force manufactures awning windows in both Classic and Ultraslim Series, built in lead-free uPVC with fusion-welded corners, argon-filled sealed glass units, and a metal-free warm-edge spacer.

How It Works

The awning sash is hinged at the top frame member and driven by a crank operator or push-out hardware. Turning the operator swings the bottom of the sash outward, and reversing it draws the sash back to close. As the sash seats, multi-point locking hardware engages along the frame and compresses the weatherstripping evenly around the full perimeter. An Encore operator system drives smooth, low-effort operation even on heavier triple-glazed or larger-format units. A Roto corner drive can be added on wide units to maintain consistent locking pressure at the upper corners.

Where It Works Best

Awning windows are most useful where ventilation is wanted but the opening needs to stay functional in the rain, or where the sill line needs to be high for privacy without sacrificing airflow. Common applications include bathrooms, laundry rooms, basement openings set high in the wall, and clerestory-level installations. Because the sash opens outward and downward, awnings work well in locations where a casement or hung window would be obstructed or awkward to reach. They are also a standard option above fixed picture windows, where they deliver ventilation without breaking the view.

Frame & Structural Design

uPVC The window system is manufactured using uPVC vinyl extrusion supplied by Vision Extrusions Group, a North American manufacturer specializing in high-performance vinyl profiles. The material is formulated to provide long-term dimensional stability, impact resistance, and resistance to discolouration under varying environmental conditions.

Internal Chambers These windows have the highest number of internal chambers, giving them out-standing insulation and sound abatement qualities, as well as thermal efficiency and increased sturdiness.

Fusion Welded Corners Provide attractive appearance & eliminate the need for adhesive and sealants. There are no imperfections on the completely watertight and airtight surface, Interior walls are also welded.

Outside Vinyl Brickmould

Inside Trim

Jamb Extensions A choice of maintenance-free uPVC, solid vinyl and wooden jamb extensions, frame moldings and corner blocks are available to enhance inside finish.

Sealed Units Sealed glass unit has 13/16” overall thickness. Depending on the model, glazing and different types and thicknesses can be applied, including double, triple and Low-E glazing (3/4” to 1-1/8)

Hidden Gasket Concealed sealing without visible rubber lines.

Designed for compatibility with standard North American wall assemblies and installation practices.

Multi-chamber vinyl frame for enhanced rigidity.

Reinforced sash construction for long-term durability.

Screen System

Screen system specifically designed for awning window configurations, ensuring a precise fit, smooth operation, and unobstructed window functionality.

Smooth vertical screen movement operates completely independently of the sash, allowing the screen to be raised or lowered at any position without opening or closing the window itself.

Interior-removable screen panel detaches quickly from inside the home without tools, making routine cleaning and seasonal maintenance simple and accessible without going outside.

Screen frame integrates seamlessly into the window unit via a concealed internal retention system that holds it firmly in place without any visible clips, fasteners, or exposed hardware on the profile.

Double Glazing

Two panes of glass separated by a sealed air or gas-filled cavity

Triple Glazing

Three panes of glass separated by two sealed insulating cavities

Frequently Asked Questions

Everything you need to know about the product and billing.

What is an awning window and how does it differ from a casement?

Both casement and awning windows are outward-opening, compression-sealed units built on the same platform. The difference is the hinge position: a casement is hinged on the side and swings open like a door, while an awning is hinged at the top and the bottom swings outward. That single change makes the awning better suited for high-sill applications and for locations that need ventilation even in light rain, since the angled glass deflects water away from the opening.

Can awning windows stay open in the rain?

Yes — this is one of the main reasons awning windows are specified for bathrooms, utility rooms, and other spaces where ventilation is needed regardless of weather. When the sash is open, the glass tilts outward and acts as a canopy, deflecting rain away from the opening. The degree of protection depends on how far the window is open and the angle of the rain, but light to moderate rainfall generally does not enter an open awning.

Are awning windows a good choice for bathrooms and high-wall openings?

Yes. Because the sash hinges at the top and opens outward, awning windows can be placed high in a wall without compromising privacy. The opening lets warm, humid air escape while the high sill keeps the interior private. They are also easier to operate than a hung or slider when placed above a bathtub or counter, since all you need is a simple crank turn rather than reaching up to lift or slide a sash.

Are awning windows available in triple-pane glazing?

Yes. Window Force awning windows are available in both double-pane (13/16″ overall) and triple-pane (1 5/16″ overall) configurations. Triple-pane improves the U-factor and reduces noise transmission, which is particularly useful in awning windows installed in bedrooms or near noise sources. Triple-pane is not available for hung or slider configurations, but is supported on casement and awning units.

What hardware is used in Window Force awning windows?

Awning units use the Encore operator system for smooth crank-driven operation, a multi-point locking system that engages at multiple points along the frame perimeter, and an optional Roto corner drive for large-format units. Hinge hardware is heavy-duty stainless steel rated for top-hinged outward loading. Handle options include Classic, Flat, and Slim locks, plus extended options including the Evo2 self-locking lever, Encore operator handle, and Fenix Evo 2 kit.

How do I clean the exterior glass on an awning window?

Unlike a casement window, which opens to 90 degrees and lets you reach the outside glass, an awning sash opens outward and downward — which does not provide the same easy exterior access. Cleaning exterior glass on awning windows typically requires access from outside or a cleaning tool that can reach around the sash. For upper-floor installations, this is worth factoring into your placement decision.
