A bi-fold door is a multi-panel door system that folds open along a track, stacking neatly to one or both sides. Each panel is hinged together, allowing the door to fold in a concertina style.
Operated smoothly with a bottom or top track and guided by rollers, bi-fold doors offer full-width openings—making them ideal for maximizing space and light. Our aluminum windows and doors are verified by third-party testing and certified by ASTM / CSA / NFRC / CE.
