The QZN series damping soundproof board consists of two specially designed high-density, high-flatness, fire-resistant A-grade magnesium oxide boards with a density of over 1000kg/m³. It is sandwiched with a specially formulated high-damping rubber pad, effectively preventing sound coupling and providing significant soundproofing performance, particularly for mid-to-low frequencies. The single-layer damping board achieves an airborne sound insulation performance of over 38dB.

The damping soundproof board has the following features: high temperature resistance, fire resistance, sound absorption, vibration resistance, insect resistance, waterproof and moisture-proof properties, non-toxicity, odorlessness, no pollution, can be directly painted or veneered, can be installed with air nails or directly tiled. It has good colorability on the surface, high strength, and flexibility, and can be used in conjunction with our company's ceiling and wall vibration isolation hangers to build room-in-room systems.
