What Are Bi-Folding Doors?
Bi-folding doors (also called folding sliding doors or concertina doors) consist of panels that fold and slide along a track, stacking neatly to one or both sides of an opening. They offer wide, unobstructed access between indoor and outdoor spaces.
How Do Bi-Folding Doors Work?
The panels are connected by hinges and run along a bottom or top track. As you push the door, the panels fold and slide together smoothly, like an accordion, creating a large opening without bulky frames.
