Covering with polystyrene boards – after painting – is the cheapest method of securing the ceiling.
The plates may be smooth (intended to be painted over) and with a pattern imprinted on the surface. We do not recommend using polystyrene over the stove in the kitchen, due to the fire hazard. Only water-based emulsion paints are suitable for painting polystyrene, due to the flammability of oil paints. You should also remember about the right glue.
Fibreboards consist of pressed wood or mineral fibers; they are much thicker than polystyrene boards. Some of them have edges that allow almost invisible tongue-and-groove boards to be joined and fastened to the ceiling skirting with staples. Others are established traditionally, on the glue. Both types of fibreboards come in smooth and convex variants. Most chipboard cladding is fireproof and sound-absorbing.
