- The simplicity of use of Gypsum plaster is one of its main credits.
- The construction of the structure becomes lighter construction with gypsum plaster.
- With Gypsum plaster, there is an extent of Better hotness protection inside structures.
- One can accomplish the accessibility of better acoustics with Gypsum plaster.
