Green Circle Bespoke Glazing

Floor to Ceiling Ventilation with an Uninterrupted Vista

Our bespoke, aluminium parallel windows give you the flexibility of a casement window, with a draught-free convection effect.

These windows open parallel to your building, affording you the comforts of ventilation, without spoiling your panoramic view.  This latest addition to our casement window range, incorporates a night vent position which can be set to an optimum position to emphasise your building’s character.  The elegant flat profile used in the manufacturing of these windows, delivers a stylish and contemporary look.

You can choose from a number of textured finishes in our hard-wearing ‘Sensations’ range, or any finish from the RAL colour palette, in single or dual colour.

Green Circle Bespoke Glazing

Parallel Windows – Increased Storm Protection

Premium parallel windows come with many benefits.  The slimline aluminium profile used, is both strong and lightweight in construction, providing slim sight lines.  A wide choice of handle finishes are available.  The increased storm protection our parallel windows provide is vital, especially when living in areas exposed to heavy wind, rain and saline air – all of which can destroy traditional timber framed windows. 

Security is paramount – our parallel windows can be PAS 24 security certified, giving you peace of mind, knowing you can sleep soundly.  They are fully compliant with Part L Building Regulations and can be Part Q specified for new build projects.

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!!”
