Sound insulation & Acoustic
Acoustic optimization

Acoustic optimization is considering how sound behaves in the room.

If the room has no sound absorbing surface, the sound will bounce from surface to surface over a long period.

The use of a surface absorber like the soft PVC will reduce the sound reflection and reverberation.

It will reduce the general ambient sound level in the room and make it possible to hear only the direct sound vibrations.

Soft PVC is combining two antagonist properties that make it unique: High density and high flexibility.

High flexibility allows to absorb a great deal of energy while high density (mass) allows this absorbed energy to be dissipated as micro-heat energy.

The high density of Polymass® makes it more efficient than many others materials in terms of the absorption of low frequencies.


  • 35 dB absorption on average
  • Thin material, does not extend the thickness of the wall or the floor.
  • Easy to install
  • Hight efficiency at low frequencies
  • Transparent if required.

Polymass® was developed with an expert acoustic engineer and can absorb around 35dB on average
