Narrow smoke curtains or draftstops serve as smoke compartmentation in buildings such as warehouses, distribution centers, commercial centers and hangars larger than 1600 m². The ITP Smoke Curtain is ideally suited for this application and certified to EN12101-1 by MPA. The smoke curtain or draftstop is an important part of the fire safety of the building. Draftstops (drop approx. min. 60cm to max. 120cm) are used to make a compartmentation of an ESFR sprinkler zone.
