Curtain-curtain EI180 14.5x9 meters for the stage of the Moscow Variety Theater

Previously, according to fire safety rules, heavy concrete slabs were installed to separate the stage and the auditorium. For this purpose, a complex scheme of lifting and lowering a fire barrier with counterweights was used. Now a large fire curtain can be made of non-flammable fabric. The design of such a fire barrier is much easier and easier to implement.
