These aluminum bifold doors also boast superior durability compared to certain other two-panel door alternatives available in the market.

4 Panel Bifold Doors With Traffic Door

A traffic door, incorporated into your bifold door setup, operates much like a standard door. It functions independently, allowing you to open and secure it without impacting the entire door configuration. The main purpose of a traffic door is to provide convenient access between your indoor and outdoor spaces, facilitating ease of movement.

Typically featuring a lever handle and key cylinder, traffic doors come with secure locking mechanisms. There are various design options: the door may be hinged to the door frame, completely separate from the bifold system, or integrated into the bifold arrangement. In the latter case, it could serve as the final door in a system with an odd number of door leaves or be positioned within one of the central leaves in a system with either an even or odd number of leaves.

Do 4 panel bifold doors have a traffic door?

However, if one door goes left and the rest go right, or vice versa, this configuration allows for a traffic door.

Wonderful service from start to finish. I came across Prime Aluminium online, after receiving a few quotes from others I found these to be the best price I could find. Delivered within the time scale promised and really pleased with the quality of the doors. Send them a picture of your door after it’s been fitted and you will be entered in to a draw for a voucher. Fingers crossed. Thank you.

Very happy with our doors, we got a few quotes from some other companies which was in excess of £10,000 for 4 bi-folds – Prime Aluminium saved us over £3000. Anyone thinking about fitting yourself just make sure there is 2 of you as the panels are about 50kg each. Will recommend in the future to anyone looking for new bifold doors.
