What is the difference between the static smoke barriers and the active smoke barriers?

Static smoke barriers installed under the ceiling or floor or hidden in the ceiling, vertical partitions that can prevent the horizontal flow of smoke and hot gases in the event of a fire. The smoke barriers can be divided into rolling curtain type and flap type according to the activity mode.

The use of active smoke barriers is more flexible, and there is no requirement for the height of the ceiling, unlike the fixed sag height of draft curtains, the ceiling is too low and not suitable for installation; while active smoke barriers are in a contracted state in daily use, which is not suitable for buildings. There is no impact on aesthetics, only when a fire occurs, will it drop to the specified position or height.
