These aluminium Bi-folding doors, are our slimmest bi-folding doors yet. Designed to bring a graceful elegance to your home, they allow for over a 90% clear opening - bringing the outside in. Our Durafold 1000 Bi-folds have very slim profiles to minimise frame and maximise the glazing area. This allows for more natural light and unobstructed views of the outside world.
They come in a wide range of different finishes including our Trend colour range. These Bi-folding doors are built to last with high quality hardware to provide a bi-folding door that slides smoothly with minimum effort. The Pendulum handle range gives this bifold great appeal and the ability to have outside access, without the need for a traffic door. Bring the outside in with our Durafold 1000 Bifolding doors.
TREND COLOUR RANGE IS CURRENTLY THE SAME PRICE AS WHITE FOR THESE DOORS.
