Casement Windows

Casement windows are side-hinged and swing open on a single action, like a small door. One handle, one movement, and the sash clears the frame completely — which gives the widest unobstructed opening of any operable window and the best cross-ventilation.

Custom-fabricated in aluminum to your openings, with multi-point locking hardware and concealed hinges. Available opening inward or outward.

How casement windows work

One handle, one movement. The sash clears the frame completely.

Casement sashes can be specified to open inward or outward. Outward-opening keeps the room clear and is the more common choice on North American projects. Inward-opening lets you clean the exterior glass from inside and never conflicts with a screen, an awning or anything mounted outside the opening.

Finishes

Two coating systems, the full RAL range in both, and a different colour inside and out if you want one.

Standard

Powder coating

Baked-on polyester, electrostatically applied and oven-cured. The standard finish on most projects and the right choice inland and in the mountains.

Full RAL range

Matte, satin and textured

Hard, scratch-resistant surface

Good colour retention

Upgrade

PVDF

A fluoropolymer coating specified where exposure is severe — coastal salt air, intense UV, or an elevation that takes weather all day. Markedly better resistance to fading and chalking than polyester.

Full RAL range

Superior UV and fade resistance

Resists chalking and salt-air corrosion

Specified for coastal and high-exposure work

Different colour inside and out

Different colour inside and out

Any unit can be finished in one colour on the interior face and another on the exterior. A warm interior tone against a dark exterior is the most common request — it lets the window match the room without fighting the elevation. Dual-colour changes nothing about thermal or structural performance.

Where casement works best

Egress bedrooms

A fully clear opening makes egress compliance straightforward where a partial-opening sash would not qualify.

Rooms that need cross-ventilation

An open casement catches and directs air across a room better than any sliding or tilting configuration.

Over counters and sinks

Single-handle operation is easy at a reach, and the sash clears the opening completely.

Should casement windows open inward or outward?

Should casement windows open inward or outward?

Casement sashes can be specified to open inward or outward. Outward-opening keeps the room clear and is the more common choice on North American projects. Inward-opening lets you clean the exterior glass from inside and never conflicts with a screen, an awning or anything mounted outside the opening.

Are casement windows better than double-hung?

Are casement windows better than double-hung?

They open differently rather than simply performing better. A casement swings fully clear on multi-point locking hardware that compresses the sash into the frame at several points, giving a wider unobstructed opening and better cross-ventilation than a sash that slides within its own frame. Which is right for a project depends on the opening, the view and how the room needs to ventilate.

Do casement windows meet egress requirements?

Do casement windows meet egress requirements?

A fully clear opening makes egress compliance straightforward where a partial-opening sash would not qualify. Because the entire aperture clears when the casement swings open, there is nothing in the opening restricting the path out.
