Trident Bi Fold Doors

Designed and manufactured in Great Britain and made from the highest-grade aluminium, the Trident Bi-Fold Door is an expertly crafted door system, perfect for any type of home.

Whether incorporated into a new-build, an extension or an older period-style property, the door’s expansive glass panels give you an uninterrupted widescreen view of the outdoors, letting you enjoy your home and its surroundings all year round.

Main Security Features:

Your home isn’t a home if it doesn’t feel secure. That’s why we’ve made sure our bi-fold doors exceed the latest security standards (including PAS 24). Employing a unique 8-point locking system, the doors come equipped with:

Heavy-duty zinc hinges designed to resist attacks from the most determined intruders
A cylinder lock proven to withstand common housebreaking techniques such as snapping, picking, drilling and bumping

Combine these high-quality features with extremely strong aluminium frames and you have a door system where security is second to none.

 Trustindex verifies that the original source of the review is Google. Was treated as a valued customer from initial enquiry to fitting for my replacement windows.  Good product at a competitive price, great fitters who left everything clean and tidy and a local family firm who know the meaning of customer service I could not have wished for better.  Would recommend Trident without hesitation.

 Trustindex verifies that the original source of the review is Google. We are so pleased with our windows, the anthracite grey flush fit has transformed the look of the house and service throughout has been superb, from sales to fitting! Really pleased to support a local business, big thank you to Glen, and Luke, Ned and all the fitters.

 Trustindex verifies that the original source of the review is Google. We have had Trident windows replace all windows and doors in a phased approach over the last couple of years.  We have found their pricing to be competitive and the sales service efficient and friendly.   Survey and subsequent installation has always happened as planned and fitters work in a clean and tidy manner.  We did have an after install issue on one occasion and a phone call to the office saw a fitter quickly come round and the issue resolved the same day.
I would not hesitate to recommend Trident.

 Trustindex verifies that the original source of the review is Google. Fantastic service from Trident Windows who fixed one of our window frames, enabled us to open our kitchen window again, fitted new glass in one of our windows and enabled us to shut two small windows that hadn't shut properly in years. From the initial consultation done by Glenn to the measurements and then final fitting by Alex and Simon, it was a great experience and pleasure dealing with all of them. Not only are our windows fixed now, they even re-aligned our front door which now opens and closes much better (and wasn't even something we knew we needed doing). A job well done - will definitely recommend to friends and family! Thank you

 Trustindex verifies that the original source of the review is Google. Thank you Trident. We are so pleased with everything from start to finish. Glen has been brilliant from the start, listening to what we wanted and giving us advice on what would suit us based on what we were planning to do with the property. This was unlike others who came to quote us, and very much why we chose Trident!

The guys who came and rectified issues with our existing windows (not fitted by Trident) and fit our new window and doors, were also great, polite, friendly and tidy. The office staff have also been great and helped us rectify a slight issue that we had with our front door quickly and with no bother. Thank you.

We would highly recommend Trident and will use them again.

 Trustindex verifies that the original source of the review is Google. We recently had a double glazed door fitted. This is our second project with Trident. From start to finish they were extremely professional in making sure from initial quote (very competitive) to fitting was a seamless experience. Would certainly have no hesitation in recommending and using them again.
