A New Era of Innovation

Sheerline Aluminium Doors

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 in endless colour options, have made aluminium windows & doors the ‘product of choice’ among architects. With Sheerline aluminium doors 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 door profiles have retained the slim aesthetic desired by aluminium doors, 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

The Sheerline Prestige bi-fold offers refined looks, exceptional thermal performance and outstanding operation. Sheerline have designed a bi-folding door that has all of the features and benefits of the best bi-folds available, and then offers some more. The doors are also available in two styling options to ensure aesthetic consistency with the Sheerline range. The incorporation of their patented construction method eliminates misaligned corner issues prevalent in ordinary aluminium frames.

The ultimate panoramic lift & slide door. Demonstrating exceptional quality and unrivalled thermal efficiency. With two interlock options, this door is up to 31% slimmer than it’s competitors, both looking, and operating like the premium patio door that it is. Available in both dual and triple track options, as well as in either the contemporary or stepped style, the lift & slide door is the ideal solution to open up a wall and picture frame a stunning view of the scenery outside.

A flawless blend of modern performance, futuristic thermal efficiency and a timeless traditional appearance. Finished with a period inspired lockbox, the Heritage single and French doors are a stunning choice for a characterful home. Unlike many other systems, Sheerline’s Heritage doors achieve Document L compliance, enabling their use within extensions and newbuild homes.

High quality, innovative and versatile, Prestige single and French doors let light flood in to open up interiors.

The doors are also available in two styling options to ensure aesthetic consistency with the Sheerline range.

Styling Options

A choice of either traditional or contemporary styling options are available in each of these aluminium door profiles barring the Heritage doors which are stepped.

The ‘Stepped’ style is inspired by traditional steel windows, and the ‘Contemporary’ style has a much more modern, minimalistic look. 

Sheerline have the perfect style door system to suit every style of home.

Features & Benefits

Concealed Drainage

Say goodbye to unsightly face drainage caps. Unlike most aluminium systems, Sheerline systems offer concealed drainage which allows water to be dispersed through the external cill. This creates a much cleaner aesthetic and prevents visible holes in frames from lost drainage caps.

Threshold Options

All Sheerline door systems are available with multiple threshold options. Previously, where items such as sliding doors were installed they were available with a standard threshold option only. Sheerline have added multiple options which make is possible to have less of a trip hazard regardless of your chosen door style.
