What Are Bifold Doors?
Bifold doors are the name for what you may recognise as folding sliding doors. Also referred to as bifold patio doors or concertina doors, external bifold doors pretty much do what they say on the tin.
They are made from a series of panels that fold like a concertina and are a popular design choice in many homes for connecting an internal space to an external space. Bifold doors can have many panels and run across a track on the bottom of the door frame, sliding across using wheels.
They fold away out of sight for a discreet closure, providing an unparalleled method for creating wide-open vistas in the home.
Aluminium Bifold Doors
Aluminium bifold doors are a stylishly sleek folding door option that can look great in a modern or traditional home. Theyâre lightweight but just as durable as timber bifold doors. If youâre looking for a more discreet bifold door option to fit seamlessly into your home, aluminium bifold doors offer a slim profile and a very compact stacking formation which also works to minimise shadows cast by the frames. Aluminium bifold doors also offer more custom design options in contrast to timber bifold doors.
Our aluminium sliding doors are available in low or level threshold designs, which allows for equal floor finishes without compromising on weatherproofing. This also means that any risk of trips or falls is greatly minimised as the bottom of the bifold doors donât jut out at all. They’re fitted with reliable locking mechanisms to ensure peace of mind regarding the security of your home. All of our doors are fully weather-rated by British Standards and surpass British Building Regulations.

What Are the Benefits of Bifold Doors?
01 natural light
External bifold doors provide the perfect solution for connecting or partitioning an outdoor area. The seamless transition from indoors to outdoors is an attractive feature for anyone looking to bring natural light and a sense of openness to what may be a quite enclosed home, or to continue an open-plan theme.
02 space-saving Design
The effortless close and unobtrusive stack of folding sliding doors allow for a beautiful space-saving solution, making a room feel vastly more open and light. Small rooms or small houses can really benefit from the increased visual space that an external bifold door offers. Internal bifold doors are also very in at the moment and are a fantastic option to add aesthetic value and functionality to a shower, for example.
03 Energy Efficiency
Not only do these doors have real aesthetic appeal, but they are also energy-efficient, completely secure and high in demand; a bifold door can really increase the value of a property and is entirely worth the investment.
