Our patented† corner jointing method eliminates the need for crimping and specialised machinery, drastically reducing waste while also speeding up manufacturing. Products can be manufactured on a single work bench with minimal training. This construction method also helps eliminate misaligned frames, and allows sections damaged during manufacture to be replaced – reducing waste.

Inside every Sheerline, window, door and lantern is our innovative Thermlock^® multi-chamber technology, helping keep properties well insulated against the worst of the UK weather.

Insulating chambers act as a thermal break and work in conjunction with high performance glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks. Helping keep homes snug and warm.

Made from the most recycled and abundant metal in the Earth’s crust and produced in the most energy efficient aluminium window facility in the UK, all Sheerline products are manufactured in the most sustainable way possible.

Our state-of-the-art, energy efficient SMS HYBREX press delivers energy savings of up to 55% compared to traditional presses. The design of our systems also vastly reduces fabrication waste, minimising the unnecessary consumption of raw material and helping reduce your window and door’s carbon footprint. This coupled to the high level of energy efficiency built into every Sheerline product helps build towards a greener future for all.
