These types of ceilings help to hide the various irregularities of the “native” ceiling, and it is beautiful to “cover” a variety of wiring, grates of the ventilation system and other little things. Suspended ceiling is a whole system that includes a metal frame, special rails and modules, plates themselves, as well as additional devices. As for decorative panels — they are often made of metal, mineral fibers, pressed paper, chipboard and even drywall.
