  2. The tough and slender fibers of sound-absorbing and noise-reducing cotton form a flexible porous connection structure, which can reduce the transmission of sound.
  3. Anti-mold and anti-bacterial, rock wool has good respiration, after water-proof treatment, there is no microbial growth environment to control the production of mold.
  4. Good thermal insulation performance, save energy, protect the environment, reduce energy consumption, reduce greenhouse effect and carbon dioxide emissions.

The rock wool thermal insulation core material used in the external wall thermal insulation board machine is made of natural rock as the main raw material. It has flame retardant and dimensional stability, and is a non-combustible thermal insulation material.
