Bifold doors come in an array of design and panel options, and also offer the largest opening space from all the door types available.

Our aluminium bifold doors are available for supply only, to be installed by an experienced builder, or can come fully installed by our in-house team of skilled installers. Bifold doors over 75kg will need site glazing, which will attract an additional cost if using your own builder as they don’t have the skills to do site glazing. Also, there can be logistical issues waiting on a glazier for site glazing.  It is recommended that you use the Window Factory installers who can undertake the installation of the bifold and include site glazing for you at no additional cost.

What are bifold doors?

Bifold doors are hinged, folding doors. They have multiple leaves that fold away, and are available in a number of configurations, which has given rise to them being referred to by the name concertina doors. The cost for aluminium doors will depend on the options you choose, across size, glazing options, framing and finishes.

When to use bifold doors

Bifold doors are a great way to blur the line between the indoor and outdoor areas, making them perfect for decks or patios to help create a beautiful open entertaining space. Aluminium bifold doors take up less space since they fold into .

Bifold door configurations

You can choose whether you want your bifold door to open outwards or inwards. We have a range of bifold configurations for you to choose from, see images below. We also offer lay-back or standard aluminium bifold doors. Lay-back is when a 1 or 2 panel bifold folds back 180 degrees against the wall.

Some important things to consider when selecting a bifold door are:

  • Configuration e.g. 2+ 1 or 3 one way
  • Suite of bifold as we have a selection available
  • Single glazing or double glazing or low e double glazing
  • Lay-back or standard
  • Standard aluminium or thermally broken aluminium 

‘Lay-back’ doors are available in 2-panel, 2+1, 1+2 and 2+2 configurations. This option is ideal for small outdoor spaces where the standard panels would be in the way allowing the doors to fold back against the exterior wall. Combination of layback one direction and standard panels the other direction is also available.
