It conforms to modern green building standards, and its low density can effectively reduce the building load and improve the seismic grade of buildings. It has good sound insulation effect, effectively reduces noise interference, and has excellent thermal insulation performance, which can improve the stability of indoor temperature. As the covering layer of floor heating system, gypsum self-leveling can evenly distribute heat and avoid cracking caused by thermal expansion and contraction. Environmental protection and non-toxic products do not contain harmful substances such as formaldehyde and benzene, and there is no pungent smell during construction, which is harmless to human body and environment.
