Folding Sliding Doors | Timber & Wooden Bi-Fold Door Designs

Bi-fold doors

Bi-fold doors create a seamless connection between your house and garden. Timber stability is essential – if it swells, the doors won’t open properly. That’s why Accoya is used for its exceptional dimensional stability, ensuring smooth operation in all weather conditions. All of our timber bifold doors are top-hung for reliability and ease of use.

Bi-fold door variations

Bringing the outside in.

Our wooden bi-fold doors, also known as folding sliding doors, timber folding doors,
or folding and stacking doors, are available in a number of variations ranging from 2 to 10 panels. These configurations can create stunning, large glazed areas, allowing more natural light to enter a room. They can be tailored to suit a wide range of apertures and are the perfect solution for maximising space and truly ‘bringing the outside in’.

Bi-fold doors open outwards and feature various configurations of door leaves supported at the head. They are pre-hung with all hardware installed at the factory and then disassembled for ease of transportation and site installation. Westbury ensures that all folding sliding doors meet the highest standards and are manufactured to precise measurements, ensuring they fold and slide perfectly.

3 leaf configuration

A compact, practical solution that maximises natural light while saving space, ideal for smaller openings that still want the benefits of wooden bifold doors.

4 leaf configuration

A balanced configuration offering flexibility and a broader opening to the outdoors, perfect for medium-sized spaces.

5 leaf configuration

Expands the opening further, creating a generous transition between home and garden. A popular choice for homeowners wanting a wider glazed expanse with timber bifold doors.

6 leaf configuration

If you are looking for a larger configuration that offers maximum flexibility and an expansive opening to the outdoors, we offer 6–10-leaf timber folding doors, ideal for large extensions and garden rooms.

What they say

The service we received was first-class

We gave a sizeable order to Westbury Windows for our new build house. The service we received was first class. We went to their factory before giving them our order and we were very impressed with what we saw. They were very pleasant and a joy to deal with. Nothing was too much trouble and they responded to all enquiries efficiently. We were very satisfied with everything that was produced for us and would highly recommend them to anyone.

Amazing windows and doors

My wife and I got in touch with Westbury not really knowing what we wanted for our Garden Room, all we knew was we didn’t want the normal. We met with Rob and his team and can honestly say we were hooked and loved the products that Westbury had to offer. We used the Westbury fitters to install the product and we couldn’t be happier with the final result. Extremely professional from start to finish and provided us an amazing product!

We’re very pleased with our roof lantern

We purchased a roof lantern from Westbury at the end of last year and our experience from start to finish was brilliant. Our sales advisor, Rob, was superb. He guided us through the process, steering the design so it really complemented our Georgian house. In hindsight our original idea wasn’t quite right and Rob was really knowledgeable when it came to getting this right for us. After install we had a couple of remedial bits but the after sales team immediately arranged for somebody to come and have a look and it was all rectified pretty swiftly. We’re really pleased with the end result and would definitely recommend Westbury.
