Applications

What bi-fold doors do that sliding doors cannot

Bi-fold doors meeting at a building corner

Corner enclosures

Two runs meet at the corner. Closed it is a glazed room; folded, both walls open.

Bi-fold doors folded open between a living room and a terrace

Terrace openings

Panels fold and stack as you push, so the living space and the terrace become one room.

Full-width bi-fold door panels stacked to one side during installation

Full-width openings

Panels stack to one side, clearing the whole opening. A sliding door always leaves half the opening closed.
