External bifold doors are glass panel doors that use a track system to slide and fold as they open. The 4 panels can be opened in the same way as a standard sliding door, typically sitting flush with the frame when closed. They are a popular choice as they create a seamless transition between your indoor and outdoor space. Here at Express, we stock a range of 3 pane bifold doors in both uPVC and aluminium, with our most recent addition being the industrial style Heritage Bifold Door - a real showpiece.
4 door bifolds come in an impressive range of sizes, including 2990mm (10ft) through to an impressive 3590mm (12ft). If you are unsure of which bifolding door is right for you, check out our guide on how to choose your bifold door or call us and we'll be happy to assist you.
As with all external bifold doors, you have the option to choose a left or right opening to fold your doors back. When you move up to a 4 panel bifolding door, you have the option of a 3+1 - giving you an access door for daily use. Remember, when ordering, you are always viewing your property from the outside.
All of our 4 panel bifold doors are supplied fully glazed as standard. Each of the 4 panels holds a double-glazed unit.
Our 4 panel bifolding doors range from £2,393 to £4,749, with the price depending on size, material and finish.

Every set comes with a 10 year guarantee as standard, regardless of price point.
This range covers external patio bifold doors. If you're after internal folding doors, our dedicated Internal Bifold Doors range is the one to shop.
Frequently Asked Questions
Bifold doors (also called folding doors or bi-folding doors) are external doors made of multiple glazed panels that concertina back against each other on a track, rather than swinging open like a French door. Panels fold flush against the frame or wall when fully open, so almost the entire opening becomes usable space. They're built from multiple glass panels, typically 2, 3, 4 or more, depending on the width of your opening. A 4 panel bifold door uses four glazed panels and usually runs as a 3+1 configuration, with one panel doubling as a daily-use access door.
Yes, our 4 panel bifold doors are available in thermally broken aluminium as well as uPVC, in widths of 3000mm and 3600mm. Aluminium finishes include Black, Grey and White, including the industrial-style Heritage aluminium range. Configurations come as 1 Left/3 Right or 3 Left/1 Right, giving you a single access door within the 4 panel set. All aluminium sets carry a 10 year guarantee, and Part Q compliant options are available with Secured by Design multipoint locking.
