Description Fire and smoke curtains represent the modern evolution of passive fire protection. Unlike bulky rolling shutters, these curtains are constructed from high-tech, stainless-steel-reinforced fiberglass fabric that is thin enough to be hidden in a ceiling void. When the building’s fire alarm or smoke detector is activated, the curtain descends at a controlled rate via a fail-safe gravity-drop system. Fire curtains focus on stopping the spread of flames, while smoke curtains are specifically engineered to create a “smoke reservoir,” preventing the lateral spread of lethal gases and keeping escape routes clear. Often used in lobbies, atria, and escalators, these systems allow architects to maintain vast, open spaces without compromising on stringent life-safety building codes like UL 1784 and BS EN 12101. Key Features Architectural Integration: The low-profile headbox and side guides can be recessed into ceilings and walls, making the system invisible when not in use. Fail-Safe “Gravity-Drop”: Designed to descend at a controlled speed even in the event of a total power failure or battery depletion. High-Tech Fabric: Made from woven fiberglass filaments, often coated with aluminum or silicone to enhance heat reflection and smoke impermeability. Dual-Action Functionality: Can be programmed to drop in stages?first to a “header” height to trap smoke, then a full drop to contain flames after a set delay. Split-Drop / Emergency Retract: Includes “obstruction sensors” and can be fitted with a manual override button to allow people to pass through during evacuation.
