Chova Viscolam High Density Sound Dampening Membrane

Product Description

Chova Viscolam 65 Mass Loaded Vinyl is an elastic high density viscous membrane, specially designed to improve sound insulation in various soundproofing systems. It is an excellent barrier to noise transmission due to material properties such as high density (1600 kg / m3), strong isolation factor and required elasticity.

Technical Specifications:

  • Thickness (mm): 2mm / 4mm / 6mm
  • Density (kg / m3): 1600 kg / m³
  • Average weight (kg / m²): 3.2 – 9.6
  • Sound insulation (Rw, dB): Upto 67 dB for airborne and impact noise
  • Calculations. Test LABEIN B130 by CT-109 I


  1. Cut a portion of ViscoLAM according to the size of the partition designed for soundproofing using a cutting tool.
  2. Fix ViscoLAM on the gypsum board in any of the following ways:
    1. Through metal screws with fixing washer
    2. Using brackets (8, 10 or 12 mm)
