The best aluminium bi-folding doors

With their smooth, easy operation and slim sightlines, aluminium bi-folds are the perfect choice for a range of applications and are equally suited to light residential and heavy-duty commercial use, providing a seamless transition with effortless operation. These doors are designed to maximise the intake of natural light, offering a bright and airy atmosphere to any space.

By providing a maximum opening width with minimum intrusion on interior floor space, each door leaf folds back and can be designed to slide either left or right, ensuring that ample natural light floods into the room, creating a vibrant and inviting environment. Whether it's for residential or commercial settings, these aluminium bi-folding doors are an excellent choice to enhance both aesthetics and the well-being of occupants by harnessing the power of natural light.

We use only the best aluminium profile systems, fabricating the ever-popular aluminium bi-fold door using the market-leading Smart Systems profile and Cortizo.


Four ways we can supply you with bi-folding doors in the UK

1. Delivered to you manufactured

We offer fast and secure delivery of our unglazed aluminium bi-fold doors throughout the UK. These doors are delivered to you fully assembled, with the option of choosing glazed or unglazed. If you opt for the glazed version, the glass will be provided separately for added protection during transit. Rest assured, our delivery service is efficient and reliable, ensuring your doors reach you promptly and in perfect condition.

2. Delivered to you in kit form

For projects where there is limited access to the property, we can supply kit form aluminium bi-folding doors. These are pre-assembled, taken apart, and then delivered to you – with the sashes still put together but separate from the outer frame – ready to be easily put back together on-site.

3. Delivered to you in flat pack

If you are on a tight deadline, we can supply flat-pack aluminium bi-fold doors with a quick lead time. Doors cannot be assembled on site but can easily be assembled in your workshop ready for installation. Our flat pack aluminium bi-fold supply service is ideal for UK uPVC businesses who buy in aluminium rather than manufacture.

4. Fast powder coating service

We are proud to offer all our trade customers fast lead times on any RAL-coloured aluminium frames, thanks to our in-house powder coating facility. With this service, you can choose from a wide range of colours to perfectly match your design needs, and we will swiftly apply a durable, high-quality finish to the frames, enhancing both their aesthetics and longevity. Whether you opt for our manufactured, kit form, or flat-pack bi-folding doors, our powder coating service ensures your doors will stand out and withstand the test of time.

Exploring Bifold Doors: Insights and Enquiries

What are some frequently asked questions about bifold doors?

Welcome to our FAQs section about Bifold Doors, where we'll provide you with valuable insights and information about the perfect solution for enhancing indoor-outdoor connectivity and maximising natural light intake. Discover the benefits of bifold door systems and how TWR Group offers quality aluminium bi-fold doors solutions for trade and commercial projects. Let's delve into the world of stylish and efficient bifold doors!

What are bifold doors, and how do they differ from traditional doors?

Bifold doors, also known as bifolding doors, are a type of door system that consists of multiple panels connected by hinges. Unlike traditional doors that swing open and close on a fixed axis, bifold doors slide and fold to one or both sides, creating a wide opening. This design allows for a seamless transition between indoors and outdoors, making them an ideal choice for spaces that require an open and spacious feel. The innovative bifold door system provides a perfect solution for connecting living spaces with patios, gardens, or balconies, offering an unobstructed view of the surroundings and bringing in abundant natural light.

What are the benefits of installing bifold doors in a property?

Bifold doors offer numerous advantages that make them a popular choice for homeowners and businesses alike. Some key benefits include:
Maximised Natural Light: Bifold doors feature large glazing areas that allow ample sunlight to enter the interior, brightening up the living space and reducing the need for artificial lighting during the day.

Improved Indoor-Outdoor Connectivity: The folding mechanism of bifold doors enables a smooth transition between indoor and outdoor spaces, creating a sense of continuity and providing an inviting atmosphere for gatherings and events.

Enhanced Space Efficiency: Bifold doors fold neatly to the side, taking up minimal space compared to traditional doors. This makes them an excellent choice for smaller rooms or areas where space optimisation is crucial.

Energy Efficiency: Quality bifold doors, like the ones offered by TWR Group with a U-value as low as 1.5W/m²K, provide excellent thermal insulation, reducing energy consumption and lowering utility bills.

Aesthetics and Versatility: Bifold doors come in various designs, finishes, and colours, allowing homeowners to choose the style that complements their property. They can also be used as room dividers or to create flexible living spaces.
