NCC composite sound insulation board The composite damping sound insulation board is made of inorganic materials of different densities on both sides, sandwiched with polymer damping glue, sandwich structure high-pressure composite molding, forming a damping restraint structure, changing the resonance frequency of the original material, and multiplying the air sound insulation of the original material. Structural sound insulation. Features Inorganic absolute, environmentally friendly materials, high-strength panels, superior sound transmission loss performance. Cost-effective and suitable for large-scale construction. It is suitable for the improvement and transformation of the sound insulation of the original walls and ceilings between the walls and the original walls and ceilings of family houses, hotel rooms, leisure clubs, mass-version ktv and other structures.

The center cushioning layer of the NCC composite shock-absorbing rubber sound insulation board is made of high-elasticity, aging-resistant and flame-retardant YMS/EVA material, and the front and back panels are made of inorganic materials with different densities and thicknesses, forming the structural characteristics of sound insulation and shock absorption materials, effectively isolating medium and low frequency and secondary low frequency sound transmission. The characteristic soft sandwich cavity can effectively save the air sound insulation and the sound transmission effect of the shear structure, which can reduce the cavity size and the complex shock absorption structure after the sound insulation layer is built.
