Why choose Arch Windows

Bespoke radius forming

Each arch profile is heat-formed to the exact radius of your specific opening — semicircle, ellipse, or segmental — so the finished window sits flush with no gap or filler strip.

Heritage compatible

Available in wood-effect foil finishes — Rosewood, Golden Oak, Anthracite — that replicate traditional timber aesthetics while delivering the maintenance-free longevity of uPVC.

Full-perimeter GI strength

Galvanised iron reinforcement follows the entire curved geometry, preventing frame creep across the span and maintaining the tight seal every Cliffer product is built for.
