Especially for the countries of Eastern Europe, Armstrong offers a set of mineral -fibrous Prima suspension ceilings, which are completely moisture resistant, multifunctional, and most importantly not expensive. This will make their installation even at the early stage of the decoration of the room, even if the windows are not already glazed and wet work is underway. The surface of the ceiling slabs is perforated, this provides excellent sound insulation. There are eight types of sets of Prima ceiling plates, various shades and with a variety of finishing edges. The difference between these suspended ceilings is that they can have various types of textures, such as rough (Dune plus), with a embossed surface (adria), with perforation (CASA) or smooth white (Plain).
