I don't think it is necessary to install a ceiling at home, but it must be installed, and there is still a big difference before and after the decoration. The first is the most obvious aesthetic problem. If you install a ceiling, you can choose your favorite ceiling shape, and it will definitely look much better at home. There are also some ceilings with many functions. For example, I know that the integrated ceiling of AIA brand is composed of various combined modules. If you have this demand, the functions will definitely be richer.
