Reduce External Noise And Lower Your Energy Bill With uPVC Casement Windows
Casement windows have been commonplace in Australia for many years. The key lock enables you to open the window to your preferred depth, so you can allow as much or as little breeze as you want to enter your home. Plus, because they open outwards, it still means you can enjoy your proffered choice of blinds.
By incorporating US-designed hardware into our European uPVC profiles, we have reimagined the traditional casement as an energy-efficient uPVC window. You’ll be able to make your home more comfortable, reduce external noise and slash your energy bills!
What are Casement Windows?
Casement windows are side-hinged windows where the opening sash is attached to the frame along one edge, allowing the window to swing outward like a door. The term “casement” refers specifically to the part of the window that opens, and the design has been a staple of Australian homes for decades.
Unlike sliding or sash windows, casement windows open with a simple handle and key lock, giving you full control over how wide the window opens. This makes them easy to operate even in hard-to-reach spots like high bathroom windows. Because they open outward, they also work perfectly with roller blinds and other internal window treatments.
A few things make casement windows stand out from other styles:
- They are typically taller than wide, making them well suited to rooms with high ceilings or where you want to maximise natural light.
- The outward-opening design funnels breezes effectively into your home while deflecting rain away from the interior.
- They can be installed as single or double openings, and a fixed panel can be added between two casement windows where a wider span is needed.
- Every Ultimate Windows casement window is custom-made to fit your opening precisely, so there are no gaps, no compromises, and no off-the-shelf sizing issues.
While the upfront cost of quality casement windows is higher than some alternatives, the long-term return in energy savings, comfort, and durability makes them a sound investment.
Why Choose Double Glazed Casement Windows?
Once a casement window is shut and locked, it creates one of the tightest seals available in any window style. That seal is the foundation of its energy efficiency, and when you add double or triple glazing into the mix, the performance gains are substantial.
Our uPVC casement windows combine European uPVC profiles with US-designed hardware to deliver a product that is built specifically for Australian conditions. The UV-stable tropical mix used in our profiles is engineered to handle intense sun exposure without warping, fading, or degrading over time.
The tight seal that makes casement windows so energy efficient also makes them one of the most secure window types available. There is no mechanism that can be manipulated from outside, and our multi-point locking system adds further protection.
Professional Casement Windows Installation in Melbourne and Canberra
Choosing the right product is only half the equation. Poor installation can undo the benefits of even the best window, leading to draughts, moisture ingress, and security vulnerabilities. At Ultimate Windows, our installation team brings years of hands-on experience to every job across Melbourne and Canberra.
Every installation begins with a precise measure of your existing openings. Because our windows are custom-made to your specifications, the fit is exact and the seal is complete from day one. Our team handles everything from removal of your existing windows through to final inspection, leaving your home clean, secure, and noticeably more comfortable.

- Are casement windows suitable for all home styles?

Yes. The versatility of casement window design means they work well in both traditional and contemporary properties. Custom sizing and a wide range of colour options make it straightforward to match the style of your home.
- How do casement windows compare to sliding windows for energy efficiency?
-
Casement windows generally outperform sliding windows for energy efficiency because the closing mechanism pulls the sash firmly against the frame, creating a continuous seal. Sliding windows rely on a track-based seal, which is more prone to gaps over time.
- How do I maintain uPVC casement windows?
-
uPVC requires very little maintenance. Wipe down the frames with a damp cloth periodically, and lubricate the hinges and locking hardware every few months to keep everything operating smoothly. Avoid abrasive cleaners on the profiles or glass.
- Can I get opaque glass in a casement window?

es. We offer opaque glass options for bathrooms, ensuites, and any other space where privacy is a priority, without compromising on the window's performance or style.
