Gypsum, a hydrated sulphate form of calcium, is one of the most commonly used false ceiling materials. Gypsum false ceilings are pre-designed. Once the desired shape, size, and design of the false ceiling are decided upon, it can easily be installed. It sports a smooth, seamless finish and is known to absorb heat and noise. Being light-weight, it can easily be hung from an iron board from the original ceiling. A false gypsum ceiling would look best in your living room.
