Tecsound S100 Acoustic Membrane

Tecsound S100 Acoustic Membrane

Soundproofing Membrane

Tecsound S100 acoustic membrane is a high density visco-elastic polymer-based, asphalt-free, synthetic soundproofing layer, that offers good acoustic insulation in different building elements. It is equipped with a self-adhesive layer, to allow its direct application on the majority of building surfaces.

Tecsound S100 soundproofing membrane has outstanding sound insulating properties. Most construction products do not provide damping. Plasterboard and plywood materials absorb little sound energy because of their rigidity. Tecsound acoustic membrane with it’s mass, density and visco-elastic properties provides superior acoustic performance to basic gypsum plasterboard wall and ceiling constructions.

Tecsound S100 Acoustic Membrane provides the best of both worlds, high additional mass and high damping.


  • High acoustic insulation, combined with soft, flexible elements
  • Weight – 10.0kg per m² @ 5mm thickness
  • Viscoelastic properties
  • Easy handling and adaptable to uneven surfaces
  • Bonds to most types of surfaces
  • Acts as a vapour control layer
  • Cold and heat resistant
  • Excellent ageing resistance
  • Rotproof

Tecsound S100 is suggested for use as follows

  • Soundproofing against airborne noise in lightweight partition walls
  • Soundproofing against airborne noise in ceilings and lightweight roofs
  • Reduction of impact noise level in all types of floors, sandwiched between floor slabs and loose-laid flooring
  • Damping of impact noise caused by rain or hail on metal decks
  • Insulation of gutter pipes
  • Sound damping of metal sheets
  • Soundproofing of booths and machine-rooms
