Aluminium Casement Windows

Discover unparalleled elegance and efficiency with The Belgravia Group’s aluminium casement windows.

Beautiful Aesthetics with Casement Windows

Their sleek, contemporary frames not only provide an elegant aesthetic that enhances any architectural design but also offer superior functionality. 

Promising Style and Substance

The minimalist sightlines, at just 70mm, allow for expansive, unobstructed views, bringing the outdoors in and filling your living space with natural light. This design maximises the glass-to-frame ratio, ensuring a modern look while boosting your home’s overall ambience. Additionally, the customisable nature of these windows means they can be tailored to your specific needs, whether you require slimline or heavy-duty sashes, or prefer outward opening, side hung, top hung, or fixed units.

Beyond aesthetics, aluminium casement windows deliver exceptional performance. Constructed from premium grade aluminium, they are incredibly durable and lightweight, ensuring a long lifespan with minimal maintenance. The 32mm thermal break zone and U-values starting from 1.0 W/m²K provide excellent thermal efficiency, which not only enhances comfort but also contributes to significant energy savings. Furthermore, these windows offer high acoustic performance with insulated glass standard at 34/36RW, ensuring a serene home environment free from external noise. With the added benefit of security hardware meeting PAS 24 standards, aluminium casement windows provide a secure, efficient, and stylish solution for any home.
