The wall adopts a multi-layer composite design, including sound insulation, sound absorption and shock absorption layers. These multi-layer materials work synergistically to effectively block sound transmission, while providing excellent fire resistance, complying with environmental standards, and creating a safe and quiet user environment. The extra-thick wall is filled with sound insulation and thermal insulation modules, as well as eco-friendly flame-retardant polyester fiber sound-absorbing decorative layers. The sound insulation panels feature fire and explosion resistance, and are treated with a chrome-plated process to ensure they never rust or fade.
