A New Era of Innovation

Sheerline Aluminium Windows

Aluminium windows & doors are known for their clean, simple aesthetics and slim sight lines. These features, along with the fact that they are low maintenance, long lasting and available endless colour options, have made aluminium windows & doors the ‘product of choice’ among architects. With Sheerline aluminium windows, we have raised the bar even higher.

Energy efficiency has become a primary focus due to both energy cost increases, and changes in building regulations. Many aluminium window systems either struggle, or cannot meet current U-Value requirements set by building regulations for newbuild properties. This means options for newbuilds are more limited than before, and regulations are going to become even more strict in the coming years.

With our Sheerline systems, we provide the most thermally advanced aluminium systems in the glazing sector. Encompassing innovation and cutting edge technology, Sheerline is a is a step ahead of the rest. These window profiles have retained the slim aesthetic desired by aluminium windows, and are able to achieve U-Values that far exceed regulations.


One of the greatest innovations in aluminium windows is Thermlock®. The multi-chamber thermal design helps keep your property well insulated against the worst of the UK weather. The insulating chambers act as a thermal break and provide phenomenal thermal performance. Far superior to a traditional polyamide thermal break, Thermlock® sets Sheerline apart from the industry standard and provides regulation beating, bill saving U-Values. Sheerline’s cills also feature the same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.

Product Range

Ultra slim, high performance aluminium windows. Classic are the slimmest of the Sheerline aluminium window range. For ultimate security, a beadless option is also available which eliminates the need for separate glazing beads. Instead, the patented corner jointing method securely locks the glass within a completely sealed unit. No window in its class is as secure.

Stylish, warm aluminium built on innovation. Prestige is Sheerline’s premium offering. The ultimate balance between style and performance, the Prestige window provides a clean, slim aesthetic and unparalleled energy performance. A patented construction method helps eliminate misaligned corner issues that can occur on ordinary aluminium frames further demonstrating the flawless quality.

Styling Options

A choice of either traditional or contemporary styling options are available in each of these aluminium window profiles. The ‘Stepped’ style is inspired by traditional steel windows, and the ‘Contemporary’ style has a much more modern, minimalistic look. 

The stepped and contemporary styles are also available in both standard and flush casement options. Flush casement windows bring both the perimeter and the opening sash perfectly in-line with each other the create perfect, evenly balanced sight lines. Read more about flush windows here.
