Bifold door materials

When it comes to choosing the right bifold doors for your home, you'll have the choice between several materials for the frame. Each comes with its own pros and cons and will ultimately influence the final cost of the bifold doors.


uPVC is the cheapest material and, as a result, the most popular material used for windows in the UK. It's widely recognised as the white plastic-looking material – common on new build homes – but is available in a variety of styles and can even resemble the woodgrain of timber.


Arguably the most modern, sophisticated and stylish option when it comes to choosing a material for bifold doors is aluminium. Even better, they don't need much maintenance at all, a wipe every now and then is enough to do the job.


For the traditional look, timber is your best option. This is a naturally beautiful material that fits perfectly with period properties. However, compared to uPCV and aluminium, timber requires much more maintenance.


Struggling to decide between aluminium and timber? Composite offers the best of both worlds by bonding together the materials. Combining the benefits of these two materials makes composite a long-lasting, strong and durable material.

Bifold door styles

When looking into bifold doors you'll notice they're given 3 numbers that look something like a football formation, for example 5-4-1. These numbers are very important to understanding how the doors work.

Each of these numbers gives you a different bit of information about the bifold doors. The first number is the total number of doors, while the middle number tells you how many of those panels open to the left and the final number is how many open to the right. So in the case of 5-4-1, there are 5 panels with 4 opening to the left and 1 to the right.

Bifold doors are commonly seen in a single straight line along the back of the house but it's also possible to have them wrap around a corner.

Bifold doors vs sliding doors

When looking to install doors leading out to the garden, bifold doors often come up against sliding doors. The key difference here is that while bifold doors slide along to the end of the opening and fold into each other – maximising the space – one side of the sliding doors remains stationary, meaning that you only have half the amount of space to pass through.

As well as offering less space to pass through, sliding doors often come with a similar or higher price tag – especially if you're considering aluminium frames.

How much do bifold doors cost to install?

There isn't an across the board price for bifold door installation, instead costs will differ depending on a number of factors, including:

  • Whether there's an existing opening that's suitable for bifold doors
  • Number of panels
  • Bifold door material
  • Whereabouts in the UK you are (installer rates can differ from place to place)
  • The installer you hire

Ultimately, the final price will come down to the installer you hire as each will have their own rates. For this reason, we highly recommend getting multiple quotes so that you can be confident that you're not being overcharged.

The simplest of installations, where there's an existing opening in the wall, could cost between £150 – £500 for the labour and take up to a day and a half. Any installation more complicated and time consuming will see the labour go above £500.
