"Yes,it is"!
It usually comes out,"Plafone",but it is ceiling tiles.They come in all types.the "cheapest" are made of styrofoam and look like crap.The best are "Celotex",and other US brands.If you are having some installed,insist on being shown an example of the work first.The installation cost should be very low.There are all classes of installers!
