Bifolding Doors For Connected Spaces

Crafted with care and made from premium aluminium profiles and high-specification glass, our aluminium bifold doors fill your room with natural daylight and look spectacular, thanks to their elegant frame profiles and designer door handles.

Slimline profiles give you more glass and modern styling creates a focal-point bifold door in any room. Fully open, our bifolding doors create a great transition to your patio area or garden. An optional flush or low track merges your inside flooring with outside decking or slabs with a minimal step-over—the finest bifold doors for any property project.

Suitable for replacing your dated patio doors or a new extension, all our bifolding doors are bespoke-made to your precise sizes, design, colour and handle choices. A choice of mullion sightlines lets you choose from the slimmest contemporary look or a more classically styled door. Standard or larger door panel sizes give you further scope, allowing you to choose standard door panels or wider and taller sizes, creating expansive folding sliding walls for a newly built opening. All our bifolds integrate perfectly with our range of aluminium windows, residential doors and roof glazing. Let natural light fill your home with our bifolding doors.

Our Reynaers premium bifolding doors come with the latest security, extensive weather protection and excellent thermal insulation, helping lower your energy bills. At the same time, they meet the requirements of current Building Regulations for insulation and airflow. Enhanced security and insulation upgrades are also available.

Making your new bifolding doors personal, C&A Window Systems provide the entire spectrum of RAL colours, metallic finishes, or dual colours. You can also choose from a range of profile styles, contemporary or more traditional, slim or standard mullion sightlines and flexible bifold panel sizes.

Answers to popular questions about bifolding doors

Bifolding doors provide an excellent patio door solution for property renovations and new builds. Here we answer some of the most common questions about this door type, but do get in touch for advice about bifolds for your project.

Are bifolds doors reliable?

The aluminium bifold has been on the market for many years already and is now better-engineered, slimmer, more reliable, secure and energy-efficient. When well-made and installed, bifold doors are very reliable patio doors. Bad installation and manufacturing usually cause problems, rarely a fault with the design of a bifold itself.

What are the benefits of Reynaers bifold doors?

Reynaers Aluminium is one of the best aluminium brands, with a long aluminium pedigree. All their windows and doors, including their bifold, have some of the best design and engineering, first-class quality hardware, outstandingly smooth slide-and-fold action and beautiful door hardware. Invest in a Reynaers bifold and you are enhancing your home with a premier brand, promising to transform any room.

Can you get a low threshold with bifold doors?

Reynaers is one of the very few bifold door brands offering several low-threshold options, whereas many other systems offer just one. If you are looking to create a low threshold for your patio doors, choosing the right bifold door gives you exactly the right design with no loss of weather protection. Even lower tracks are suitable for use inside the home, making the floor track virtually flush.

Do bifold doors make a room cold?

Modern aluminium bifolds have thermally insulated frames, very well insulated safety glass, and other great design features. As a result, they are energy-efficient and save money on energy bills. Bifold doors do not make a room cold. You can enhance the standard thermal performance to make your bifold doors better insulated.

What is better, bifold doors or sliding doors?

There are certain benefits you only get with a bifold. A bifold opens up the entire opening. The traffic door design lets you use them like regular doors when closed. Bifold doors also let you enter your property from outside with key access. And bifold doors also create matching single doors or French doors for elsewhere in your home, even down to matching handles. Sliding doors are better when you want the biggest possible panes of glass and fewer visible mullions. Both options are different and have their individual benefits.
