3 tips for optimal sound insulation

How well a facing shell works,
depends mainly on these 3 factors:

1. insulation material that is as resilient as possible

The so-called dynamic stiffness indicates how good the spring effect of an insulation material is for facing shells. The value should be below 10. The SilentFiber sound insulation board has a very low dynamic stiffness value of s' = 4.5 MN/m3. Thus, the sustainable board can "cushion" the sound particularly well.

3. mass of the surface layer as high as possible

The higher the mass per unit area of the facing layer, the higher the improvement in sound insulation. We recommend using particularly heavy sound insulation gypsum boards. Knauf Diamant or Knauf Silentboard, for example, are suitable here.

The lower the dynamic stiffness of the insulation layer, the higher the area-related mass of the facing layer and the deeper the facing layer itself, the greater the improvement in sound insulation provided by the facing structures.
