We can see the smoke blocking barrier in many large shopping mall and office buildings, What is the function ?
The function of the smoke curtain is to prevent the smoke or hot air from flowing freely laterally under the ceiling when a fire occurs, so as to strengthen the smoke exhaust effect of each partition,prevent fire expansion.
According to the different installation methods, there are two situations for the smoke blocking wall, one is fixed, the material is required to be non-flammable, and the sag height must be more than 50 cm.
Another one is movable smoke curtain ,which is controlled by central controller. When the sensor senses the smoke concentration or the temperature reaches the set value, it will droop automatically.
