Benefits of bifold doors

Open plan

The main benefit of bifold systems is that they provide a wide opening, which offers easy access and also allows light and air to flow throughout your premises.

Room divider

Bifold windows and doors are great as a room divider, which can be opened to offer both privacy or a open area.


The most common materials used to manufacturer bifold doors are aluminium and glass, which combine to present a contemporary alternative to standard door systems.


Stack to one side

Bifold doors consist of multiple panels that stack to one side when opened.

Top track wheels

The doors are usually connected to a track system located above the doors, which contains rollers to enable easy operation.

High traffic areas such as shops and restaurants, where the doors are used every day, generally require a heavy duty design that can handle this daily use.

Some manufacturers have used lighter grade systems in the past, which have caused problems with the glass.

Available in a range of colours

Aluminium frames are usually powder coated in a wide range of colours to suit any colour scheme, while timber bifold doors are mainly stained or painted to your preferred colour.
