Sheerline

At Sheerline, we take a fresh approach to aluminium. Designed around a wider thermal break than legacy aluminium systems, our windows and doors are designed to meet the latest requirements of the built environment.

Full of innovation we hold a King's Award for Enterprise in Innovation 2025, and numerous other awards including being voted Aluminium Systems Company of the Year in the National Fenestration Awards.

Our systems are available fully internally beaded, and packed full of clever features, with matching aesthetics across all products, perfect for the most exacting projects.

A modern system architecture, built around a patented corner jointing method, reduces fabrication waste and locks in quality. Designed and manufactured in the UK, by the UK’s leading fenestration experts, Sheerline is available on agile lead times, helping you meet contract schedules.
