Compared to traditional patio doors or existing two-panel sliding doors, selecting a three-pane aluminum bifold door offers a significantly wider clear opening when fully folded back. This translates to a more expansive usable area and enhanced access from the garden to the house.

These aluminum bifold doors also exhibit superior durability compared to some other two-panel door alternatives on the market.

3 Panel Bifold Doors With Traffic Door

A traffic door, integrated within your bifold door system, functions similarly to a traditional door. It operates independently, allowing you to open and lock it without affecting the entire door assembly. The primary purpose of a traffic door is to offer convenient access between your indoor and outdoor spaces, enhancing ease of movement.

Typically equipped with a lever handle and key cylinder, traffic doors provide secure locking mechanisms. Design options vary: the door may be hinged to the door frame, completely separate from the bifold system, or integrated into the bifold setup. In the latter scenario, it could serve as the final door in a system with an odd number of door leaves or be situated within one of the central leaves in a system with either an even or odd number of leaves.

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.
