What Are Casement Windows?

View our Projects

Casement windows are the most popular window style in the UK — and it's easy to see why. Hinged at the side and opening outward, they offer maximum ventilation, excellent security and a clean, timeless look that suits virtually any property style across St Austell and the surrounding area. Our uPVC and aluminium casement windows are A-rated as standard, available in a huge range of colours, finishes and configurations — from simple side-hung casements to top-hung and combination units with fixed panes. Every casement window we install is FENSA registered and backed by our 10-year insurance-backed guarantee.

Our uPVC casement windows combine A-rated thermal performance with low maintenance, excellent security and outstanding value. Available in white, cream and a wide range of woodgrain and solid colours, they suit period and modern homes across St Austell and the surrounding area.
For a slim-profile, high-performance alternative — our aluminium casement windows offer thermally broken frames with ultra-narrow sightlines and maximum glazed area. Available in any RAL colour and ideal for contemporary homes and renovations.
We supply casement windows in side-hung, top-hung and combination configurations to suit any opening. Whether you need a simple single casement or a complex multi-pane unit with fixed lights, our team will design the right solution for your home.
Every casement window is supplied with A-rated double glazed units featuring Low-E glass, argon gas filling and warm-edge spacer bars as standard. Triple glazing is available for maximum thermal and acoustic performance.
