Key Takeaways
- A casement window is hinged at the side and swings open like a door, usually worked with a handle or crank.
- Casement windows seal tightly when closed and give excellent ventilation because the whole sash opens.
- In Melbourne, double glazed uPVC casement windows typically cost from $2,100 to $3,400 or more installed, depending on size, glass and options.
- They are best on walls with clear space outside, and less suited to busy walkways where an open sash could be hit.
What Are Casement Windows?
A casement window is a window with a sash that is hinged along one side. When you turn the handle, the sash swings outward on its hinges, much like a small door.
Because the entire window opens, casements can catch breezes from the side and direct them into the room. They are one of the most common window styles in Australia for bedrooms, kitchens and living areas.
- Side-hinged sash: opens outward on hinges at one edge.
- Handle or crank: operated by a lever or winder, which is easy to reach even over a bench.
- Single or paired: available as one sash or as two sashes meeting in the middle.
- Clear view: few internal bars, so the glass area is large.
How Casement Windows Work
When closed, the sash presses against a compression seal fitted around the frame. That pressure is what gives casements their reputation for airtightness.
When opened, hardware holds the sash at the angle you choose. The design needs clear space outside, so it suits walls facing gardens and courtyards better than narrow paths.
Pros and Cons of Casement Windows
No window style is perfect for every room. This summary shows where casement windows shine and where another style may suit you better.
| Advantages | Disadvantages |
|---|---|
| Excellent ventilation, since the full sash opens | Needs clearance outside for the sash to swing |
| Tight seal when closed with compression gaskets | Open sashes can catch strong wind if not secured |
| Unobstructed views and plenty of light | Cannot always accommodate a window-mounted air conditioner |
| Secure locking with key-lockable hardware | Usually costs more than a basic sliding window |
| Easy to operate, even with limited reach | Flyscreens sit inside, so cleaning takes a little care |
Many of the drawbacks are manageable with good hardware and sensible placement. Choosing quality components makes a noticeable difference.
Casement Windows in uPVC
Ultimate Windows combines US-designed hardware with European uPVC profiles in its casement range. The profiles are multi-chamber, which helps insulation, and the frame needs no repainting.
Our double glazed casement windows include features that support both comfort and security.
- Double compression seals: block draughts and help with noise.
- Key-lockable hardware: adds peace of mind when you are away.
- Double or triple glazing: choose the level of insulation that fits your climate and budget.
- Argon gas as standard: included at no extra cost in double glazed units.
- Low maintenance: uPVC does not need repainting and typically lasts 25 to 30 years.

Casement Windows Compared With Other Styles
The right style depends on how the room is used and what is outside the window. Two common alternatives are awning and sliding windows.
- Awning windows: hinged at the top and open outward, so they can stay open in light rain. See what awning windows offer for comparison.
- Sliding windows: slide sideways and need no outward clearance, but open only part of the frame.
- Tilt and turn windows: open inward and tilt for ventilation, with a very tight seal.
If you are still deciding, our guide on choosing the right window style walks through each room.
Where Casement Windows Work Best
Casement windows are a strong choice when ventilation and sealing are both priorities. Think about each position in your home before you decide.
- Pick walls where the sash can swing out without hitting plants, paths or furniture.
- Use casements in bedrooms and living rooms where airflow and quiet matter.
- Choose them over kitchen sinks, as the crank handle is easier to reach than a sliding latch.
- Avoid placing them beside busy walkways or tight balconies.
- Consider an awning window where you want ventilation in light rain.
Our uPVC windows are up to 4.5 times more energy efficient than standard aluminium-framed windows, so well-sealed casements can help your comfort year round.
Care and Maintenance Tips
Casement windows are simple to look after, and uPVC makes the job easier. A few regular checks keep the seals and hardware working for years.
- Wipe the frame: use warm water and mild soap, with no abrasive cleaners that scratch uPVC.
- Clean the seals: remove dust and grit from the gaskets so the sash closes fully.
- Lubricate hardware: a light silicone-based lubricant keeps hinges and the crank moving smoothly.
- Check the locks: make sure the handle pulls the sash firmly against the frame.
- Close in strong wind: secure open sashes during storms to protect the hinges.
- Clear the drainage slots: small channels in the frame must stay free of dirt so water can drain.

Frequently Asked Questions
How does a casement window work?
A casement window is hinged on one side and opens outward when you turn a handle or crank. When closed, the sash presses against a compression seal in the frame. Locking hardware then holds it firmly shut, which gives a tight seal.
Are casement windows energy efficient?
They can be very efficient because the sash closes against compression seals, which limit air leaks. Pairing a casement with a uPVC frame, double glazing, Low-E glass and argon gas improves insulation further. Efficiency also depends on installation quality, so a careful fit matters.
How much do casement windows cost in Melbourne?
Double glazed uPVC casement windows typically cost from $2,100 to $3,400 or more installed in Melbourne. The final price depends on window size, glass type such as Low-E or acoustic laminated, hardware and the number of windows ordered. A free measure gives you an exact fixed price.
Can casement windows be double glazed?
Yes. Casement windows suit double glazing and triple glazing well because the sash is sturdy and seals tightly against the frame. Ultimate Windows offers casement windows with double or triple glazing, with argon gas included as standard in double glazed units.
