Built with ultra-slim sightlines, precision bottom-rolling mechanisms, thermal efficiency and multipoint PAS 24 security, Durajoin supplies and installs aluminium and uPVC bi-folding systems across Greater London and the Home Counties.
At Durajoin, we manufacture, supply and install bifolding doors in London and across Greater London to suit the requirements of each project. From replacing existing patio doors to incorporating a large opening into a new extension, we can help you choose a suitable material, configuration, glazing and finish. Our range includes both aluminium bifold doors and uPVC bifold doors, giving homeowners and professionals different options depending on the property’s design and requirements.
Slim profiles and strong construction make aluminium bifolding doors a popular option for larger openings and contemporary properties. They can be made to measure with a choice of configurations, colours, glazing and hardware.
uPVC bifold doors offer a practical, low-maintenance alternative for residential projects. They are available in different configurations and finishes to suit a range of homes and extensions. Ideal for direct patio door replacements within standard opening sizes.
Selecting the right frame material determines your sightlines, maximum opening size, thermal performance, and overall budget. Compare the core differences to choose the optimal setup for your London property.

Bifold doors can transform how a room connects with the outdoors, creating a wider opening while allowing plenty of natural light into the property. With made-to-measure configurations, different materials, glazing and finishes available, they can be designed to suit the style, space and practical requirements of your home. Here are the benefits:
Folding panels allow a large section of the opening to be opened, creating a stronger connection between indoor and outdoor areas.
Large glazed panels allow more daylight into your home and can help create a brighter, more open feeling.
Bifold doors can be designed around wider openings, making them particularly suitable for extensions and renovations where a larger glazed area is required.
With different materials, colours, glazing and hardware available, bifold doors can be specified to complement both contemporary and traditional properties.
