UPVC Folding Doors and Aluminium Bifold Doors in Northampton, Northamptonshire

Folding doors (also known as multifold doors, sliding doors, bi fold doors, concertina doors or folding sliding doors) have become more popular over recent years, and are regulary featured in home improvement programmes or design shows. However folding doors are not new, as we have been manufacturing and installing folding doors for Northampton, Northamptonshire since 1988.

The popularity of folding doors across Northamptonshire has arisen as they provide an excellent panoramic view to the outside whilst maximising the opening to the outdoors. Folding doors can be installed to replace an existing patio door or french door, and can be used to open up conservatories, sunrooms or anywhere where you have a wide access.

In Northampton, Northamptonshire, we offer both aluminium folding doors and upvc folding doors. Both types offer high levels of security and excellent thermal and acoustic performance.

Both aluminium folding doors and upvc folding doors are available in a wide range of styles / configurations. All folding door styles are available opening inwards or opening outwards. For more information on styles, sizes and technical information please follow the links below:

I was looking at the composite doors as we have just moved and had one on our previous house.

We visited your shop on Saturday at around 2pm and I cannot praise enough the effectiveness of your sales prevention officer. There we were, ready to place an order for two doors with the possibility of further purchases for our other properties. But even though we were the only people in the shop, the man in the office didn't not come out and talk to us, prefering instead to do some filing and make a trip out to the back of the store. Most sales staff I have encounetered would have eventually relented and spoken to us, but not this gentleman. His dedication to the art of sales prevention was consumate - I salute you sir!

Good initial way of getting a quotation but no response when trying to firm up on a more detailed quotation. The following is required 'Please revise quote to allow for glazed side panel with transome. Total opening size 1135w X 2070h. Door standard 762mm.'
