Bifold door definition

Bifold doors are also known as bi-folding doors, folding sliding doors, glass sliding doors and sliding room dividers. In its simplest term, a bifold is a door that slides open while its panels fold up and stack neatly against the wall – like a concertina.

What is a bifolding door?

Bifold doors often connect rooms to an outdoor area, such as an entrance to a garden or conservatory, but they can be used for a variety of purposes. Typically, a bifold can have anything between two to seven panels that are connected with hinges and attached to rollers at the top or bottom.

Often a bifold will feature a traffic door. This is a door at one end of the bifold that opens like a standard entrance door, allowing continued use of the bifold throughout the colder months without having to push all the panels back.

One of the ‘deal clinchers’ of bifold doors is that they offer spectacular views to outside. Aluminium frames support large glass panes and offer slim sightlines for an unimpeded view, compared to traditional patio doors.

Bifold doors are a much sought after product in both the domestic and commercial markets. It is increasingly popular home improvement, as seen on many DIY programmes such as Grand Designs or DIY SOS.
