What are Bi-Fold Doors?

Bi-fold doors are typically a set of 2 or more standard size glass doors that open in a concertina style and neatly fold flat when open. Unlike a sliding patio door, that remains only half open, Bi-fold doors fully open to seamlessly connect your living space with your terrace, patio or garden.
