False ceiling goes by many names, such as grid ceiling, suspended ceiling, T-bar ceiling or drop ceiling. This is essentially an artificial roof, created as a minimal extension of the existing roof. False roofs were previously used only in commercial structures. Over time, they have also become an integral part of the home, as they give a certain charm to the interior of the home. The space between the actual roof and the false can be used to install lighting or as air conditioning vents.
