Are you in the market for a robust and secure composite stable door?

Composite stable doors, also known as half-and-half doors, offer the blend of security and convenience that homeowners desire. One of the main advantages of a composite stable door is the ability to open the top section for ventilation while keeping children and pets safe indoors. This combination of window functionality and composite door security makes composite stable doors a popular choice.

Built to high-performance standards, composite stable doors provide the same level of security, durability, and low maintenance as other composite doors.

By integrating the traditional functionality of a stable door with modern uPVC technology, composite stable doors are suitable for various home styles, whether it’s a traditional country cottage or a modern townhouse, prioritizing both convenience and security.

What house's are stable doors suitable for?

Stable doors are available in a variety of designs and materials, allowing them to adapt to a range of architectural styles, from contemporary to classic.


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.
