At Direct Doors, we know doors, and on this page we’ll help you choose the ideal set of folding doors for a price that suits your budget.

With over 30 years of sourcing and installing doors, we can advise you of the very best options for your situation. What we’ve learned more than most is that the right choice of doors comes down to quality and style, rather than price.

But if you’re looking for the right doors at the right price, you’ve come to the right place.

We’ll guide you through the process of choosing your new set of doors, helping you understand the various styles, materials, and finishes.


Our oak, hardwood, and white fully finished external folding doors are all supplied with the glass factory-installed in the doors.

The glass used in all of our internal and external models is toughened safety glass, in order to comply with British standards. The aluminium bi-folding doors also have safety double glazing as standard.

And where we state that the folding doors are supplied in ‘kit form’, we can assure you that the glass or panels are always fitted and that they are hinged together to form a bi-fold pair.

The frames and the locking mechanism are supplied pre-machined and in kit form, ready for immediate installation.

Measuring and Fitting:

First, we must advise that if you’re not an experienced DIY enthusiast, you may wish to seek the assistance of a seasoned joiner to help you measure and fit your new folding doors.

And please note: The DIY advice provided on our website is only a guideline for the installation of interior doors. We cannot accept liability for any mishap, injury or damage caused to you, your property or a third party while following this advice.

Our unrivalled experience in fitting folding doors means we can advise on which doors in our product range can be cut, and by how much, in both height and width.

If you’d like more information on the entire measuring and fitting process, visit our Help Section.

When measuring your folding doors, ignore the current door size and follow the advice below. Be aware that in most cases there are locating pins to the top and bottom of most bi-fold doors

Width: Measure each opening between the frame at the top, the middle and the bottom.

Select a door set that fits the widest size. This is because the widest size can be adjusted by you to suit the narrow area of any part of the opening without compromising the stability or affecting the look of the doors - small adjustments to each door edge can help you find just the right size but is not a recommended process for exterior doors.

Height: Measure from the carpet/floor covering to the underside of the timber lintol.

Thickness: Now and only now do you measure the door to find out how thick it is at present. With interior doors you may have to compromise and fit a slightly thinner door. This does not normally present any problems.
