Aluminium Bi Fold Doors

Aluminium bi fold doors are one of the most desirable home improvements of the past decade. These folding doors have a sleek, thin frame that gives your home a contemporary look with bigger glazed areas to let the light flood a room.

Bi Fold Doors

Fold the panels away on warm days to combine your garden and living space as one, or stay cosy on a winters day with an unrivalled feeling of spaciousness.

Anglian aluminium bi fold doors open concertina style and are mounted on tracks to slide and fold away smoothly. Choose from a 2-7 panel configuration depending on your project and the option to open inwards or outwards. This makes aluminium bi fold doors work perfectly between your home and garden, or between your home and conservatory.

With a choice of more than 200 RAL colours and powder coating, these folding doors offer vibrancy that won’t wear out.

The Benefits of Bi Fold Doors

Strong and Slim

Made from a sturdy 70mm wide frame with welded corners, Anglian bi fold doors are built to last. The folding door panels are mounted in a mechanically jointed aluminium frame and given a long-lasting powder coat finish. Aluminium frames won’t contract or expand in direct sunlight, which makes them a great, low-maintenance choice.

Built to be Robust

Primary folding doors are fitted with a multi-point locking system and anti-snap, anti-pick and anti-drill Yale 3-star cylinder lock as standard. Operated by the pop-out door handle, each panel has top and bottom shoot-lock bolts that keep them securely locked in place.

Energy Efficient

Anglian ‘soft coat’ glass is designed to keep the warmth in and the cold out in winter, so there’s no need to worry about a hike in your heating bills. Our aluminium bi fold doors have a thermal break which improves the energy efficiency of the door.
