Accordion fire Doors are invaluable for protecting large open buildings from threat of fire, smoke and hot gasses. The best fire protection and smoke containment system with a recognizable means of egress.
Won-Door Accordion Fire Door Products
Accordion fire doors are UL-listed horizontal-sliding assemblies that remain concealed in wall pockets during normal operations and automatically deploy on alarm activation, providing code-compliant fire separation across wide openings while maintaining clear egress and preserving open sightliness.
