Bi-Fold Doors
A bi-fold door consists of multiple door panels connected by hinges, enabling large-scale opening through folding movement.
It does not require horizontal sliding or outward swinging. It saves space as it folds and opens effortlessly.
Boasting an expansive view and maximum ventilation, it completely clears the opening when folded. Its aesthetic transparency makes it a premium choice for connecting indoor and outdoor spaces.
