Extra Heavy-Duty Aluminium Bi-Folding Doors – Blending Magnificance with Style

Our bespoke, aluminium premium-plus bi-folding doors have been designed especially for those who want the functionality of a bi-fold, fitted to larger openings than our premium bi-folds.

These doors are manufactured from a thermally efficient, slimline aluminium profile, with a smooth-running system featuring stainless steel wheels – enabling effortless left, right, inside and outside opening, thus providing a glorious uninterrupted view.  Odd number configurations can be specified with a single access door, allowing day-to-day access, without the need for opening the whole structure.

Bespoke Premium-Plus Bi-Folding Doors – Scenic Views Without Compromise

Premium-plus bi-folding doors yield the panoramic views you desire, without compromising on essential features.  Fully weather-tested, our doors are fitted with an advanced gasketing system and advanced thermal barrier system, designed to provide exceptional weather-tightness.  Hinge gaskets are also included to prevent draughts – imperative in the winter months and resulting in a pleasant internal climate, all year round.

Doors can be specified without an external handle to retain continuous clean lines and improve security.  The bi-folds feature high security performance, including cylinder locks and a shoot-bolt system, locking into both top and bottom tracks.

What Our Clients Say

Our clients have kindly written reviews, following the conclusion of their projects.  After receiving design, manufacture and installation of our bespoke aluminium windows, doors and other fenestration products – all undertaken with meticulous care and high standards - they agreed to share their experiences...

Aluminium Bi-Fold Doors

Peter Cade - Sheviock, Devon

“Many thanks for a job well done. As you know we’re very exposed up here and I’m happy to report that after 2 winters our Bi-Folding doors are working perfectly and have stood up to the test of some very severe weather”

Integral Blind Systems

Mark Wilson - Saltash, Cornwall

“We are delighted with the result, solid well-made doors that look absolutely first class. We’re especially pleased with the integral blinds which finish off the door’s appearance and work far better than a separate system. Everything was manufactured in the time specified and their installation service was highly professional.”

Aluminium Slab Doors

Cafe 3 Sixty, Bovey Tracey

“I cannot recommend Green Circle highly enough, they made and installed our windows and doors at Cafe 3 Sixty in Bovey Tracey. The windows and doors are really high quality and sturdy. The service is so efficient but also friendly and personal. Green Circle are a excellent company to work with.”

Aluminium Casement Windows

F & O Hill, Mannamead

“High quality product and great local company, we are delighted with our bifold door and windows in our new extension. All the Green Circle staff have been a pleasure to deal with from start to finish. We highly recommend Green Circle”

Aluminium Sliding Doors

J & E Taylor - Saltash, Cornwall

“We were given a tour of their manufacturing facility and were impressed by their open, transparent approach and welcoming, professional manner. The new sliding doors are just what we had in mind. A minor post installation query was resolved within a couple of hours in a most proficient way. Well done to everyone concerned and a huge thank you!!”
