Custom Screens & Security makes aluminium casement windows to measure in our Bassendean factory and installs them across Perth and Mandurah. Casement windows are hinged on one side and open outward like a door. The whole sash swings open to catch a breeze, and it seals tightly when closed.
They suit bedrooms, living areas and narrow openings beside fixed glass. We have made security screens and doors in WA for more than 40 years, and now build Carinya aluminium windows in the same factory.
HOW DO CASEMENT WINDOWS WORK?
A casement window has a sash hinged on its left or right edge. It opens outward on friction stays, which hold the sash at the angle you set. Close it and the sash pulls in against the weather seals, where the handle locks it shut.
The whole sash swings open. A sliding window of the same size only ever opens about halfway.
Casements are often combined with fixed glass. A narrow casement beside a large fixed pane gives a room its view and its ventilation in a single frame.
WHAT ARE THE BENEFITS OF CASEMENT WINDOWS?
More fresh air from the same opening. An open casement sash works like a scoop. Angle it toward the afternoon sea breeze (the Fremantle Doctor) and it pushes cooler air into the room.
A tighter seal when closed. The sash pulls in against weather seals around the frame. That means fewer draughts and less dust blowing in.
No tracks to clean. Sliding windows have tracks that collect sand and leaves, a common problem around Perth. A casement has no bottom track for sand to clog.
A clean look inside and out. A single casement sash has no central rail across the glass to break up the view. The style suits modern builds and older character homes alike.
CASEMENT VS AWNING VS SLIDING WINDOWS
| Feature | Casement | Awning | Sliding |
|---|---|---|---|
| Hinge position | Left or right side | Top | None (sash slides) |
| How it opens | Outward, like a door | Outward from the bottom | Sideways along a track |
| Opening area for airflow | The full sash swings open | Partly, angled out from the bottom | About half the window |
| Open in light rain | No, rain can blow in | Yes | No |
| Screen position | Inside the frame | Inside the frame | Outside the frame |
| Best for | Bedrooms, living areas, catching breezes, beside fixed glass | Kitchens, bathrooms, laundries | Wide openings, walkways, budget builds |
If you want airflow in wet weather, an awning window is the better choice. If the window opens onto a path or patio, a sliding window keeps the sash out of the way.
WHY CHOOSE ALUMINIUM CASEMENT WINDOWS?
- No rot or repainting. Powder-coated aluminium frames hold their shape and finish through Perth’s heat and winter rain, unlike the timber casements found in many older homes.
- Slim frames, more glass. Aluminium is strong enough for narrow frames and sashes, which leaves more of each opening as glass.
- Any colour you like. Frames are powder-coated in a wide range of colours. See our aluminium window colour guide to compare finishes.
- Made to measure. Every window is built to the exact size of your opening.
- Low maintenance near the coast. In coastal suburbs, wash the frame and hardware every three to six months with mild soapy water, then rinse with fresh water. This removes salt and keeps the hardware working smoothly.
WHERE DO CASEMENT WINDOWS WORK BEST?
Casement windows work well in:
- Bedrooms, where the full opening gives good airflow on summer nights.
- Living areas that face the afternoon sea breeze.
- Tall, narrow openings beside fixed windows or doors.
- Wider openings, using a pair of casements or casements either side of fixed glass.
- Character homes, as a low-maintenance replacement for original timber casements.
They are less suited to windows that open onto a path or deck, where someone could walk into an open sash. They also should not be left open in strong wind. On very exposed walls, awning or sliding windows are the safer choice.
SECURITY SCREENS FOR CASEMENT WINDOWS
Because a casement sash opens outward, flyscreens and security screens are fitted on the inside of the frame. We will talk you through the screen options when we measure.
We manufacture security window screens in our own factory, including Invisi-Gard, Alu-Gard and Vision-Gard. With one fitted, you can leave your casement windows open on a warm night.
For bedrooms, ask us about Invisi-Scape emergency escape screens, which provide security from the outside while allowing quick, keyless release from inside in an emergency.
Ordering windows and screens together means a single measure and one point of contact for the warranty.
