Bi-Fold Doors

Imagine being able to open up an entire wall of your room, creating space and letting fresh air and natural daylight flood into your home. Whether you have a bedroom with Juliette balcony, a dining kitchen, a conservatory or an orangery,bi-folding doors can provide a stunning alternative to patio or French doors.

We’ve rigorously tested our bi-folding doors to make sure they exceed the appropriate British Standards for weather performance. We also subject our doors to a regime of robot cyclic testing in our purpose-built laboratory, making sure all mechanical parts will stand up to the repeated operation necessary for daily living.
