The primary function of smoke curtains is to effectively prevent smoke from horizontally spreading within buildings during fires, thereby enhancing the exhaust effect within smoke control zones.

Smoke barriers are typically made of non-combustible materials and installed on the ceiling or below suspended ceilings in buildings. They can be either fixed or movable. These barriers can automatically descend during a fire to form a vertical smoke isolation wall. Movable smoke barriers can lower automatically upon activation of temperature or smoke detection control systems, while fixed smoke barriers remain stationary.

The presence of smoke partitions aids in reducing the impact of fires on people and property, and provides better visibility for fire rescue personnel, enabling more effective extinguishing and rescue operations. Properly configuring smoke partitions and other smoke control facilities during building design and construction is crucial for enhancing a building's fire resistance.
