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 increasingly 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:

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.'
