The most common material used for installing a false ceiling in a room is plaster of Paris, commonly known as POP; it is sometimes also called the POP ceiling. POP is used widely for the false ceiling as it is easy to source and can be effortlessly molded as per the required design. They are well insulated and long-lasting even in varying weathers. The false ceiling's main function is to conceal the wiring, air conditioning ducts, and provide an aesthetic view for the room or the apartment.
A false ceiling is installed in two ways in a room. In the first method, the panels are installed directly on the beams. For this, frames are fabricated using wood or aluminum as material and are regularly spaced parallel to the beams. If the beams are of not the same height, then the frames are adjusted accordingly so that the false ceiling has a uniform frame.
In the second method, the false ceiling is directly suspended from the actual ceiling. Then the POP panels are placed on the frame, and it is ensured that there is no gap between the panels. To provide insulation; there are special insulation panels available that are installed above the POP panels.
