Fixed Flexible Smoke Curtain

1. System Overview

The Fixed Flexible Smoke Curtain is a passive smoke control and compartmentation device used in building fire protection systems. It is typically installed at the building soffit, ceiling structure, or beneath beams, and is constructed of high-temperature–resistant flexible fire-resistant material. In the event of a fire, the curtain provides physical separation to limit the horizontal spread of smoke, creating a clear and safer environment for occupant evacuation and fire-fighting operations.

As a smoke barrier that requires no power supply and no control or actuation system, the fixed flexible smoke curtain features a simple structure and high operational reliability. It is widely applied in commercial buildings, public facilities, and industrial plants, and constitutes an essential element of modern smoke compartmentation design in accordance with international fire and life safety principles.

2. Key Advantages

1. Passive Smoke Control – Safe and Reliable
   Operating without electrical power or control systems, the curtain remains permanently in place and provides stable smoke containment under fire conditions, ensuring high reliability.

2. Flexible Construction – High Adaptability
   Manufactured from flexible, high-temperature fire-resistant materials, the curtain can accommodate structural movement and installation tolerances, making it suitable for various building configurations.

3. Easy Installation and Low Maintenance Cost
   With a simple structure and no mechanical drive components, installation is straightforward and post-installation maintenance requirements are minimal.

4. Effective Smoke Spread Control
   By appropriately determining the curtain height and location, clear smoke compartments are formed. When used in conjunction with smoke exhaust systems, overall smoke control performance is significantly enhanced.

5. Minimal Impact on Building Space
   The curtain is lightweight and thin, imposing minimal structural load and making it well suited for large-volume spaces and buildings with high ceiling clearance.

3. How it works

1. Under normal conditions, the fixed flexible smoke curtain remains permanently suspended at its designated location.

2. When a fire occurs, smoke rises due to thermal buoyancy and spreads horizontally beneath the ceiling.

3. The smoke curtain provides a physical barrier that restricts lateral smoke movement.

4. Smoke is directed toward designated smoke exhaust zones or smoke management systems, establishing an effective smoke control pathway.
