A guide to installing aluminium external bifold doors, and the benefits of choosing aluminium

Martin Burgess - Customer Service Manager

Author: Martin Burgess - Customer Service Manager

Aluminium is a durable and reliable material for a bifold door. Available in a range of colours, styles and configurations - our selection of aluminium bifold doors provides an ideal option for every household.

Here, we discuss the key benefits of aluminium bifold doors, how to measure for an opening size and install aluminium bifold doors.



The benefits of aluminium bifold doors


Environmentally friendly

In terms of upfront cost, UPVC is by far the cheapest material on the market, but for many, UPVC has become an unwanted environmental issue. For example – it is highly toxic and is more difficult to recycle than options such as aluminium.

Once recycled, incredibly, the aluminium results in an equally quality aluminium product, and the entire process utilises only about 5% of the energy used to create the initial metal. Even though there are other metals that can be recycled, not many can retain their structural integrity the way aluminium does. Incredibly, 75% of all aluminium ever produced is still in circulation today.

Impressively, recycling prevents up to 90 million tons of CO2 from being released into the atmosphere every year.

Aluminium requires minimal maintenance and upkeep. Given aluminium’s innate strength and durability, it makes it resilient against flexing, warping and corroding in differing weather conditions. Aluminium doesn’t corrode, and therefore Vufold is able to offer longer product guarantees than we can on our oak /hardwood doors - as long as the doors are not situated close to the sea (see product specification sheets for details), you can enjoy 15 years peace of mind.


Large range of colour options and a powder-coated finish

One of the most enjoyed features of an aluminium bifold door is its beautiful colour and finish, achieved through a powder coating process. Some of the benefits of opting for powder-coated doors include:

  • Powder-coated surfaces are deemed more resistant to damage that can occur both naturally via the elements or from accidental damage that may show scuffs and scratches on other finish types.
  • Powder coating colours stay vibrant for longer and generally will avoid the weathered look for longer.
  • Powder coatings contain no solvents and thus are generally better for the environment than liquid finishes applied to UPVC doors.


Incredible strength

Aluminium is light and strong – and although much heavier than, for example, oak in its raw form, its inherent alloy strength means that it can be supplied in a lightweight frame. This means easy handling at installation and, most importantly, more glass and light for you to enjoy.


How does aluminium compare to steel?

Aluminium weighs 67% less than steel yet carries a lot of its strength properties. This means that it can create lighter and easier-to-operate doors and windows. Aluminium allows for slim sightlines to be achieved for maximised views and can be made in a range of configurations without compromising on performance or security.

How do you measure your opening size for aluminium external bifold doors?

Before you select your ideal bifold door from Vufold’s extensive aluminium bifold doors collection, you will need to measure the opening. If you’re unsure on how to do this – don't worry. With a few easy steps, you can successfully determine the door sizes needed for your home:

  • Step 1: Firstly, use a spirit level to measure the corners of the opening, or aperture.
  • Step 2: Next, measure the width and height of the opening in millimetres. You will need to take these measurements from each side and from the middle of the opening. The measurements you take will need to be exact, as a few incorrect millimetres can affect the way your doors fit.
  • Step 3: Once you have the key measurements, subtract 10mm from the smallest measurement you have. This will be the size of your new bifold doors.
  • Step 4: Check that you will have enough space to fold the doors back once they are installed.
  • Step 5: Take a look at Vufold’s large selection of standard-sized bifold doors. It is important to note that bifold doors have a 10-15mm fitting tolerance, so if your measurements swing outside of the standard sizes by this amount, you may still be able to install a standard-size bifold door.
  • Step 6: If your measurements still do not match up to any of the standard size doors listed, then you can order a bespoke size specially made for your opening.

Installing aluminium bifold doors

After measuring the opening size for your aluminium bifold door, you next need to check the following factors:

  • Check whether you need planning permission.
  • Check whether you have the correct measurements.
  • We recommend double-checking your opening size to ensure you choose the correct door size. If you do not take the correct measurements when ordering your bifold doors or the opening is not quite right, it can be difficult to send them back, especially if they are made-to-measure.
  • Check the position and size of the lintels in your home.

To fit your bifold doors, follow the below steps:

  • Prepare the space
  • Assemble the frame
  • Choose the opening option
  • Install the assembled frames
  • Seal the door frame
  • Fix the drop bolts and pivot door
  • Fit the middle doors
  • Adjust the doors
  • Fit the locks (if applicable) and handles.

If you are still unsure on how to install bifold doors - all of our bifold doors are supplied with easy-to-follow instructions. They are also supplied ready-to-assemble which means they can be fitted by anyone with competent DIY knowledge. The kits include everything you need for a successful installation, saving you the time and money it takes to find several tools.
