Fully glazed ultra-slim doors

Not available with any other aluminium brand, are steel-look doors in a fully glazed design, but with the same prominent and attractive feature backplate for the lock and door handles.

These doors come double-glazed with 28mm toughened glass units having a soft-coat low-emissivity coating, warm edge spacer bars and argon gas fill.  Focus on how the floating lock design gives the appearance of seamlessly blending in with the glass.

Interior door with glazing bars

Dividing a hallway and living space, our single door design with a smaller feature backplate, floating into the glass whilst still offering the steel-look with two slimline glazing bars.

Single glazed with safety glass, matching black lever/lever handle, no visible threshold and opening inwards, this style offers the best of both worlds – the iconic steel look with maximum transparency and light flowing between the rooms.

Just completed house renovation, using all the internal bespoke doors with glass panels. Absolutely delighted with the quality of doors and service. I was assisted every step of the way in getting the right size and format of extremely tall door. Keiran has been exceptionally helpful to deal with over the months from ordering to completion. 10/10I never usually do reviews but but I would say the whole experience and end result that has been achieved has been amazing.

So pleased with our new Aluco bifold doors, the best we could find on the market! We wanted bifolds with maximum glass area and no bulky frame and the Aluco doors were the perfect choice. Stunning, deep matte black colour, high quality, great choice of hardware and a first-class service. Highly recommend!

I recently had 3 sets of ALUCO exterior crital styled steel framed doors fitted to my property as part of an ongoing renovation. After looking around at various options Aluco was the only manufacturer that I felt could deliver the style I was looking for. With most other companies I thought the design was bulky and not finished to the finesse Aluco has achieved . Based on my experience I can honestly thoroughly recommend this manufacturer and will look to use them again on any future projects
