Bi-Fold Door

FLEXIBLE OPENINGS. SEAMLESS CONNECTIONS.

ALV FOLD

Fold away the boundaries between spaces.

ALV FOLD is a bi-fold glazed opening system designed to create wide, adaptable openings with a clean architectural appearance. Connected panels fold neatly to one side, opening the aperture and creating a seamless transition between adjoining spaces while maintaining a unified framed composition when closed. Ideal for residential, hospitality, and commercial applications where flexibility, openness, and visual continuity are essential.

ALV FOLD

The ALV FOLD system connects three framed glazed panels through coordinated folding junctions. As the system opens, the leaves articulate in sequence and gather into a compact folded arrangement, creating a broad, unobstructed opening. Upper and lower frame conditions work together with the folding hardware to guide smooth movement between open and closed positions.
