Sheerline's Classic double glazed windows, with standard high performance glazing have a U-value as low as 1.4 W/(m2K).
While our Prestige windows are as low as 0.9W/(m2K) when specified with triple glazing, also achieving an A+ WER (Win-dow Energy Rating)
Ultra slim 59mm sightlines of the innovative Classic window system maximises the light flooding into customers homes, giving them the architectural aluminium look they are looking for.

Our patented corner jointing method does away with the need for crimping and specialised machinery, drastically reducing waste and improving quality. Allowing for easy replacement of sealed units on site if required. Larger frames can also be assembled in situ if required.
Our unique Thermlock® closed-cell, insulating chamber, hidden away inside every Sheerline window and door act as a
thermal break, creating products with class leading thermal performance.
Sheerline’s cills, ancillaries and corner posts, also feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.
No element of the Sheerline system has been overlooked, which helps eliminate any condensation issues caused by cold bridging.
Our patented construction method – using threaded screws to bind corners tightly together in perfect unison – allows
the Classic system to be beadless, creating perfect run through mitres on internal joints, doing away with the unsightly
junctions of square cut beads seen on most aluminium windows.
We’ve also designed out the stepping of misaligned corners, allowing each Sheerline window to be individually hand tuned to improve quality.

Research and Development
Our team have investigated the limitations and flaws of current designs in fabrication, installation and sales, developing
innovations to overcome them – and the limitations and frustrations of aluminium supply.
They examined every aspect of aluminium windows and doors from performance and looks, to how they’re made, installed, and supplied. They’ve re-engineered the aluminium window from the ground up – and every component of the system has been developed in-house to be made in house. The Technical team consists of 6 full time staff with a combined window experience approaching 200 years.
