Premium Aluminium Casement Windows
Discover a window that combines contemporary design, exceptional performance, and long‑lasting strength. Our Premium Aluminium Casement Windows, engineered using the renowned Cortizo aluminium systems, deliver a sleek architectural aesthetic with impressive energy efficiency, weather protection, and customisation options. Perfect for modern homes, period properties seeking a refined upgrade, extensions, or commercial spaces — these windows offer elegance without compromise.
Sleek, Modern Design With Slim Sightlines
Aluminium allows for narrow, minimalist frames, giving you more glass and more natural light. Cortizo casement frames are designed with slim, contemporary profiles made from high‑quality aluminium, enhancing views while maintaining structural integrity.
These profiles work beautifully across a broad range of architectural styles, from crisp modern builds to character homes seeking a clean, updated look.
Outstanding Thermal Performance
Thanks to advanced thermal break technology, Cortizo aluminium casement windows achieve excellent insulation values:
- U-values from 0.9 W/m²K, depending on configuration and glazing selection.
- Engineered to deliver all-season comfort while helping reduce heat loss.
Modern aluminium has come a long way — these systems meet and exceed today’s expectations for energy efficiency without sacrificing style.
Exceptional Acoustic Comfort
Cortizo aluminium systems can reduce outside noise by up to 45 dB. That means if busy traffic outside is around 85 dB, you’d only hear roughly 40 dB indoors — about the level of a quiet library or a soft conversation. In practical terms, loud outdoor noise is transformed into a gentle background sound, creating a much calmer home environment.
Engineered for Reliability & Strength
Premium aluminium is naturally robust — but Cortizo enhances this with:
- Structurally strong profiles designed to withstand demanding weather.
- Air permeability Class 4, water tightness Class E1200, and wind resistance Class CE2400 ratings.
These windows offer durability you can trust for decades with minimal maintenance.
Tailored to Your Home
Cortizo aluminium casements support a wide range of configurations:
- Outward opening styles (side‑hung, top‑hung)
- Fixed frames, shaped frames, and bay configurations
- Slimline or heavy‑duty sashes for larger openings
With maximum sash sizes up to 1800 mm tall (depending on configuration) and glazing options up to 44 mm, the system adapts to both residential and commercial demands.

- Full RAL colour range
