Green Circle Bespoke Glazing

Deluxe, Bespoke, Aluminium Casement Windows For The Modern, Contemporary Facade

Our range of slim-line, aluminium casement windows have been designed to withstand the worst of the great, British weather. Stainless steel locking rails compress high performing gaskets for a watertight seal. In weather tests, our premium casement windows remained watertight, whilst withstanding air pressure, four times greater than the required Industry Standard (BS 6375).

Fixed frames can be designed to create large-span, Atrium and Apex windows and openings, whilst providing ‘PAS 24 Security Certified’ protection. Casements can be fully locked in a ‘Night Vent’ position, providing welcome background ventilation, without fear of someone easily opening your
window.

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...

Peter Cade - Sheviock, Devon

Premium Bi-Fold Doors

“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”

Mark Wilson - Saltash, Cornwall

Integral Blind Systems

“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.”

Cafe 3 Sixty, Bovey Tracey

Premium Aluminium Slab Doors

“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.”

F & O Hill, Mannamead

Premium Casement Windows

“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”

J & E Taylor - Saltash, Cornwall

Premium Sliding Doors

“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!!”
