What Are Aluminium Bifold Doors?

Aluminium bifolding doors are folding sliding doors made from thermally broken aluminium. They fold back on themselves and slide along a track fitted in the ceiling and floor. This means that they can open up virtually an entire wall, while taking up very little space.

They're a great alternative to sliding and french doors, offering increased functionality. 

What is Thermally Broken Aluminium?

Thermally broken aluminium frames are vital for improving energy efficiency and keeping heating bills down. As aluminium is a highly conductive material, without a thermal break, you would lose a lot of heat and your external door frames would become very hot in summer and very cold in winter.

A thermal break is an insulating layer within the frame of the door. Similar to the layer of argon within our double glazing. It helps prevent the transfer of heat. This insulating layer can be made from a variety of materials but is most often a reinforced polyamide strip fixed in between the inner and outer profiles of the frame.

Why Choose Aluminium Bi Folding Doors?

Aluminium has been a favourite for use in commercial properties for some time, due to the fact that window and door frames can be slimmer than with other materials, creating slim sight lines. This means the glass panels in your external bifold doors can be larger, which is great for homes, shop windows and offices. In recent years, aluminium folding patio doors have become more popular in homes, thanks to the advent of thermal break technology, which reduces heat loss.

Aside from its fantastic thermal performance, aluminium doors also offer the following benefits:

  • Cheaper than timber – whilst it tends to be more expensive than uPVC, aluminium is often a cheaper alternative to timber.
  • Durable – aluminium’s strength makes it the perfect material for external bifold doors, as it can stand up to the great British weather.
  • Low-maintenance – Like uPVC, aluminium is fairly low maintenance. Just give it a clean every now and again that
  • Stylish – because aluminium is so strong, door frames can be thinner than timber or uPVC, so larger panes of glass can be used. This creates a sleek and modern look. It also means external aluminium bifold doors let more natural light in and offer enhanced views of your outdoor space. Our aluminium folding doors are available in smart white or anthracite grey.
  • Energy efficient – thermally broken aluminium and argon-filled double glazed panels mean our aluminium folding doors are incredibly energy efficient (and Part L compliant). They’ll save you money on your heating bills, and cut down on noise from outside too!


As with any folding door system, the cost of your aluminium bi fold doors will depend on the size of your door opening, choice of glazing and the number of panels you need. Aluminium, while being more expensive than uPVC, is often cheaper than timber, but is also lower maintenance so will help keep costs down longer term too.


We offer our exterior aluminium bi folding doors in a range of standard sizes and panel configurations. From 1800mm 3 panel aluminium bifold doors, right up to 5 door sets to fit openings of 4800mm.
