When Are Smoke Curtains Required?
Smoke curtains are barriers designed to channel or contain away smoke and heat. They play a major part in ventilation systems of a building. Smoke curtains are completely impenetrable to smoke. They are structured to activate upon reception of a signal from a well-positioned smoke or heat detector and are becoming a compulsory accessory for smoke containment, especially in commercial buildings.

Fire Emergencies
-
Smoke curtains activate with smoke presence during fire emergencies, reducing the risk of contacting smoke. They are therefore highly recommended for public buildings, shopping malls and underground car parks.
Maintaining Smoke Boundaries
-
In some workplaces, employees are allowed to smoke outside. However, there are offices near these places that people are allowed to smoke. The smoke may get into the office and may be hazardous to the employees who do not smoke. To counter this problem, smoke curtains are installed so as to channel the smoke to a different direction, which reduces the risk of smoke penetrating into the offices and is contained on the outside.

Building Smoke Reservoirs
-
Smoke curtains are important in containment of smoke and fire gases. Smoke reservoirs are places where smoke is contained until it is rechanneled and safely extracted. The curtains are used to build smoke reservoirs in buildings to prevent smoke from spreading around. They are complete storage places for smoke, and, with the help of smoke curtains, the smoke can be contained for a long duration. The smoke is still contained until its final safe extraction whether the drop height of the curtain is long or short.
Smoke Control
-
Companies often have large buildings with seclusions for kitchens but have no chimneys. To control the smoke levels in the kitchen, smoke curtains are used. They are set up to increase the ventilation by directing the smoke to another direction where it is finally extracted. With smoke curtains, smoke levels in kitchens are kept at tolerable levels. The curtains also prevent the lateral movement of smoke; hence other rooms are kept smoke free. Smoke curtains are also applicable in large smoke control systems.
