With panels that fold back concertina style, bifold doors can increase the opening space in your home and offer convenience. Seamlessly merging your internal living space with the outside world, bifold door systems help to increase airflow and flood your home with natural light.
Despite the growing appeal of folding doors, one concern that homeowners sometimes have is whether they will need to fully fold back all the doors every time they want to go outside. However, this problem can be eliminated by including a traffic door into the bifold door system.
In this blog, we’ll help you to understand what a traffic door is and the benefits of using one.
A traffic door is a single panel door of the bifold that can open and close completely independently from the rest of the bifold system. The main purpose of a traffic door is to provide easy convenient access between your internal and external spaces, without needing to open the entire set of doors. These types of doors can also be referred to as an access or lead door.
Like a conventional door, a traffic door locks completely independently and can be used from the inside or out. In a concertina system, the traffic door can be either hinge to the door frame or attach to the bifold door configuration. There are also a range of other options depending on which best suits the layout of your home, this includes the traffic door being either positioned to the right, left or in the middle of the complete bifold.
There are endless benefits to bifold doors. Here’s just some of the benefits bifold doors have to offer.
One of the main benefits of these aluminium doors is that they maximise the amount of natural light entering a property. This can help to create the illusion of more space. This is due to their slim frames, allowing light in when they close or are fully opening.
With multi-point locking as standard, our bifold doors are one of the most secure options on the market, especially when paired with double or triple glazing. They are also fitted with a durable external handle, designed to withstand gripping tools for enhanced security. At UK Doors Online, our bi folding doors come double glazed as standard combined with security features such as an anti-snap key cylinder.
Like well known French doors, Bifold doors are essentially a wall of glass that connects your interior and exterior spaces, perfect for scenic views. They also provide convenient access to the garden or outside space when fitted with a traffic door.
Our bifold doors are incredibly energy-efficient which can help to regulate indoor temperatures and lower energy bills. You can even opt for triple glazed glass on our bifold door systems to improve thermal efficiency. However, at UK Doors Online, our doors come double glazed as standard.
Our aluminium bifold doors feature slim profile sections that are designed to minimise visible framework and maximise views of the outside. With market leading sash sizes of up to 1200mm wide and 3000mm tall, we have something for every project! Use our online designer today to create the perfect bifold doors for your space. Our bifold door set has super-slim sightlines of just 107mm, which is much slimmer than other doors on the market.

Installing a traffic door into your bifolds comes with many advantages. First, they help to maintain the internal environment by controlling the flow of air, temperature, and humidity. This makes them a great way to keep it cosy inside the house.
When the weather is warm bifolds are excellent for extending your living space into the outside. But, when the weather chills the last thing you want to do is open up your home to the cold. With a traffic door, you have easy entry throughout your property without folding back all of the doors.
At UK Doors, we promise maximum security for your home, whether or not there is a traffic door in your bifold installation. Our bifold doors feature a state-of-the-art multi-point locking system and anti-theft locking cylinders.
We also offer a range of glazing options which, combined with the multi-point locking system, create a strong, secure door. Maximise security by choosing laminated glass, designed to withstand extreme force.
Not all bi folding doors require a traffic door. If you have an alternative way of getting into your garden, or you’re happy to open the bifold door fully to access your outdoor space, then a traffic door isn’t always necessary.
However, for alternative access you might still decide to include a traffic door into the design of your bifold system.
It’s important to note that your bifold configuration will need to be an odd number of sashes in order to be able to include a traffic door. Or, your traffic door will need to open from the other side of the frame to the other sashes.
This is because each pair of sashes need to fold together, concertina style, as shown in the example image below. This will create the unique opening method that bifold doors are known for. Use our online design tool here to see what bifold configuration best suits your space. Plus, our designer let’s you explore the possibilty of including a traffic door with your design.

Alternatively, sliding patio doors can offer the benefits of including a traffic door with any number of sashes or, for smaller openings, traffic doors can still be included in your design if you opt for French doors.
