What are Bi Fold Doors?
Bifold doors are a kind of folding exterior door made up of several panels that fold back against the wall in sections as a concertina. The framed glass panels slide along a track to make them easy to open and close.
With large panes of glass that let in plenty of natural light, exterior bifold doors are usually on the back of a house leading to a patio or garden. Like traditional French doors or sliding patio doors, bifold patio doors also fit upstairs openings, such as a terrace or balcony.
Bring a little of the outdoors in with patio bifold doors or conservatory bifold doors custom made for the perfect fit. Enjoy uninterrupted views of your garden with doors that maximise the natural light flooding your home.
Bifold doors are made to measure and suitable for any size property. They can have as little as two panels for smaller homes or up to seven for larger openings.
Find a shade to suit your home from over 200 RAL colours (i). Our long-lasting powder coat finish means our bifold doors offer a vibrancy that will not wear out.
Bi folding Door Colour Options
Get creative and choose from over 200 RAL bifold door colours to match your existing windows and doors, or be bold with a contrasting colour. There is even a dual colour option for a different shade on the inner and outer frames. Keep traditional with white bifold doors or add a modern twist with Anthracite grey bifold doors.
