alumina bi-folds

Alumina is a true Bi-Fold Aluminium Bi-Fold Door system, beautifully sculptured and foiled to match perfectly with the full uPVC product suite.

Sleek, stylish and cutting-edge, Alumina bi-fold doors are a contemporary home improvement option. Alumina is a fully aluminium system featuring bi-folding, residential and French doors spanning up to 2.5m high.

designed by experts

Alumina is more than just a bi-fold system. It can also be made into flush single aluminium doors or aluminium french doors, as a perfect match to the uPVC Flush Sash window system. Alumina has a host of unique features and benefits.

Energy efficiency

Aluminium doors are not usually renowned for their high thermal efficiency, but Alumina has been designed with this in mind and can achieve U-values as low as 1.2 W/m²K. This is in part thanks to Alumina’s clever polyamide thermal locking system, providing a thermal break and preventing the transfer of heat outside the building.


As you’d expect from us, the Alumina range achieves the highest levels of security. Its built-in hardware includes multiple bi-directional locking points, shootbolts, anti-lift features and anti-bump cylinders – ensuring all Alumina aluminium doors hold Secured by Design status.

WHy Choose alumina Bi-folds?

Unlike most other aluminium doors, Alumina can be foiled with flat or woodgrain finishes. This means not only do the foils provide a ‘warm touch’ to the doors, they can match perfectly with foiled uPVC windows! Not only does this make for a seamless, attractive appearance.

If your door installation requires large expanses of glass, Alumina is ideal. Sashes spanning as high as 2.5m and as wide as 1.2m are possible and the product has been fully tested and passed at its maximum size, giving consumers peace of mind for durability and robustness.
