The authentic steel look

Aluco bifold doors – there is nothing better

Aluco bifold doors are precision-crafted doors with advanced design, sophisticated style and top-of-the-line build quality, fit and finish. A modern classic, we craft these superior folding sliding doors promising the most authentic steel-inspired styling and one of the best bifolding doors available. Other ‘steel-look’ bifolds use a standard door and simply apply glazing bars. Aluco bifold doors come with a similar stepped profile that makes our exterior French and single doors so desirable. including a matching heritage transom profile if required.

Aluco bifold doors, one of the slimmest

Adding to the incredible styling you only get with Aluco bifold doors are the slim sightlines throughout, especially at the door mullions. With your new Aluco bifold doors closed, the dimension is a mere 94mm, making Aluco one of the slimmest bifolds on the market and giving you more glass, less visible frame and more light coming into the room. Depending on the frame configuration, the surround frames are even slimmer at 88mm, as is the threshold, also available as a low set, creating a smooth transition to the outside and with a minimal step.

Steel-look bifold doors designed for modern living

Available as open in or open out, folding in one direction or on each side, Aluco bifold doors transform a room, giving you the appeal and functionality only provided by a bifold door, with the desirable steel-inspired styling that is totally on-trend. We can even create matching single or double doors using the same profiles, creating identical doors throughout the project with identical frames and hardware.

We’ve built practicality into Aluco bifold doors with the option of a traffic door, where one leaf works just like a regular door without having to fold the panels back each time. The convenience of a garden access door is built into your bifold.

Aluco bifold doors come in all manner of designs, whether you choose a fully glazed version, contemporary sash or heritage styled, with or without glazing bars or transoms. Double or triple-glazed, each is crafted with high-grade insulated aluminium, protected by your choice of beautiful colour finish and high-performance safety glass. Security is excellent with modern multipoint locking operated by robust and stylish door handles, full sealing throughout and low U-Values, comfortably meeting the requirements of current Building Regulations, depending on the glass specification chosen.

With a full choice of frame profiles, optional middle rails, cills and accessories and made in the heart of Cambridgeshire, Aluco bifold doors complement any property type, from traditional to contemporary. Only we make our products, and our carefully selected, fully trained and approved Aluco Distributors professionally install them.

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
