There is an innovative solution –smoke protection curtains The FireDoors company has developed and implemented an innovative solution for creating smoke zones and removal of smoke outside the building using flexible transformable barriers. Namely automatic accordion type smoke curtains Such construction of curtains allows implementing any bold design solutions. Initially a smoke curtain remains in the sub-ceiling space, and the visible part is at the same level with the ceiling and creates a single plane. When the fire alarm is triggered, the smoke curtain falls down to a certain level and prevents smoke penetration into the atrium or escalator area.
