There is no industrial waste, no toxic gas and no noise in the whole process of production, processing, installation and construction, which meets the requirements of energy conservation and environmental protection and reduces the burden on the environment.

[0032] 4. The materials used in the shielding room of the present invention not only have good heat insulation and sound insulation and noise reduction performance (within the frequency range of 1000-3000Hz, the sound insulation is 45dB and above), but also have decorative functions, strong surface decoration performance, simple and generous, and excellent appearance and connotation. A variety of decorative materials and colors can be used to beautify the environment, with a wide range of choices to meet the needs of different customers.
