Bi-fold interior shutters consist of hinged panels connected in pairs. Instead of opening outwards like a door, bi-fold panels fold back against one another like an accordian. Depending upon your windows or patio doors, they can either run with a track along the top and if necessary a bottom track (ideal for large glass expanses and patio doors) or operate on a simple frame with hinges. Bi-folding shutters work best on patio and sliding doors, wide double or triple windows, and as room dividers. Some applications where we have designed and installed bi-folding shutters are shown below.
