Energy Efficient

Our aluminium flush casement windows have polyamide thermal breaks for enhanced thermal performance. This helps the aluminium retain heat, just like our bespoke double glazing. The glazing traps heat between the twin panes, preventing it from escaping outside and being wasted. Homeowners can enjoy a warm and comfortable home throughout the year with the help of our aluminium flush casement windows.

By making a home more efficient with the energy it consumes, homeowners could also benefit from reduced energy bills year after year, alongside an improved carbon footprint. The sleek aesthetic and high performance glazing and thermal breaks combine style and substance, which can benefit any new build.

The glazing we use can be between 24mm-35mm thick and can provide U-values as low as 1.2 W/M2K with the triple glazing variant.


Safe & Secure

The multipoint locking mechanism that comes standard with all our aluminium flush casement windows can keep homes safe and secure against unwanted intrusion and intense weather conditions. All our aluminium flush casement windows are thoroughly tested to PAS24: 2016 requirements and are certified under the Secured by Design scheme.

Aluminium is a robust and long lasting material that is capable of withstanding heavy blows without warping, bending, or cracking. Friction stays on our side hung aluminium flush casement windows ensure advanced weather performance, and the tight weather seals can prevent cold draughts and leaks from creeping into homes when the windows are shut. Plus, our aluminium flush casement windows by Aluk are double rebated to further increase the defence against harsh weather conditions.

No matter which configuration option you choose, from French casement to flush bay, you can expect industry leading security. Our aluminium flush casement windows are available in your choice of flat, putty line or stepped edge vent style sashes to match any property and are available in top, side hung, and fixed lights.


Low Maintenance

Our aluminium flush casement windows are incredibly low maintenance, only requiring an occasional wipe down using a wet cloth or sponge. The aluminium profile is slim yet robust, which can resist wear and tear even after years of consistent use. Homeowners will never have to worry about varnishing, repainting, or sanding these aluminium flush casement windows. 

Aluminium is also easy to recycle, making the unlikely need for repairs or replacements simple and fast. The friction stays, and double rebates also help to keep out bad weather, which can prevent damage to the internal structure of the profile, offering high quality performance throughout the aluminium flush casement windows’ long lifespan.

The slim 45mm sash creates a contemporary look that allows more room for our durable double or triple glazing. These aluminium flush casement windows are available in single, dual, textured, and anodised finishes, and each can last for decades with the right cleaning routine.
