Durable, energy efficient and weatherproof, our commercial aluminium casement windows are completely versatile
Commercial casement windows are extremely versatile and work for any commercial application. All our windows are available made-to-measure and with a range of cill options.
Our aluminium windows have thermally broken aluminium frames and achieve U-values as low as 1.5 W/m²K or even 1.3 W/m²K, when combined with triple glazing.

Aluminium is robust, and the frames won’t twist or warp over time. Our aluminium commercial casement windows are coated to resist corrosion and fading, so they won’t need repainting or treating.
Our commercial casement windows have ultra-slim sightlines starting from 53mm to maximise the amount of natural light that can flow into buildings.
Get superior security with our multi-point locking system, which complies with PAS 24. For extra protection, upgrade to Secured by Design specification.
