High density viscoelastic sheet designed to improve acoustic insulation.

Recommended use

  • Reinforcement of the acoustic insulation of Dry wall (plasterboard) and wooden floor systems.
  • Refurbishment works requiring thinner solutions.
  • Soundproofing protection and vibration absorption of metal structures.
  • Suitable to be fitted to different acoustic insulation devices such as doors, screens and sound barriers.


  • Excellent barrier against   noise transmission.
  • High density (1,600 kg/m³).
  • High attenuation coefficient.
  • Low flexural modulus.
  • Reduced thickness.

A fully self-adhesive membrane is also available. It has the same features as the ViscoLAM range but with the added benefit of being very helpful for a difficult access laying such as false ceiling.
