Sheerline Aluminium Doors

Sheerline’s aluminium door systems deliver outstanding thermal performance across their Classic Heritage, Prestige, bi-fold, lift-and-slide, and entrance door ranges. The multi-chamber Thermlock® core achieves U-values as low as 0.9 W/m²K (triple glazed), meeting Part L regulations with ease. Slim sightlines (as narrow as 59 mm), full-depth Eurogrooves, and patented corner construction ensure a sleek finish, secure build, and efficient fabrication.

Designed for trade efficiency, the range features clip-in beads, pre-sealed cills, and universal profiles for stepped, contemporary, and flush aesthetics. Security includes multi-point locking, Ultion cylinders, and optional PAS24 or Secured by Design certification. With 12 stocked colour options (plus bespoke RAL finishes) and short lead times, Sheerline aluminium doors are ideal for a wide range of residential and commercial projects.

Sheerline’s Prestige Lift & Slide doors provide a high-end, smooth-gliding solution ideal for wide openings. Their lift-before-slide operation ensures panels glide effortlessly, even at large sizes. The narrow 52mm sightlines offer uninterrupted views and a premium look. Dual and triple track options can allow configurations with up to four panes. 

Thermal performance is excellent thanks to Thermlock® multi-chamber insulation, delivering U-values as low as 1.0 W/m²K with triple glazing. These doors meet PAS24 standards and offer enhanced “Secured by Design” options. With low-threshold, Part M-compliant access and integrated drainage, they’re well-suited for both residential and light commercial applications.

Sheerline’s Prestige Bi-Folds offer a premium folding door solution with ultra-slim 138mm sightlines and smooth, reliable performance. The unique single roller design supports easy operation, while doors fold and stack efficiently to create wide, open spaces—up to 7 panes wide and over 7 metres.

These doors also benefit from Thermlock® thermal breaks and achieve U-values as low as 1.0 W/m²K when specified with triple glazing, delivering outstanding energy efficiency. The doors also offer enhanced safety, with secure multi-point locking, including interlocks and a ‘Thunderbolt’ shootbolt mechanism. Configurable with low, level, or ramped thresholds, they are ideal for projects that demand both style and accessibility. The combination of strength, thermal efficiency, and minimal frames makes them a standout option for contemporary extensions and renovations.

The Index bifold doors blend Sheerline’s premium engineering with a more efficient design. It offers excellent thermal performance with U-values down to 1.4 W/m²K with double glazing, and  1.0 W/m²K using triple glazing. This makes them the perfect product to offer alongside the Prestige bifold doors range. 

These doors use a simplified fabrication process and quick-fit features like clip-in beads and pre-set gaskets, saving time on your installations. Security features include a clever passive door lock with a clean finger pull, making it secure yet user-friendly. Stocked in popular colours, it’s a perfect choice for installers who balance performance with cost efficiency.
