Tecsound SY – Self-Adhesive Acoustic Membrane


Tecsound® is a synthetic soundproofing membrane, which has a built-in self-adhesive layer enabling it to be applied straight onto most surfaces.

Dimensions designed specially for application on gypsum plasterboard.


  • Airborne noise insulation in vertical surfaces with low surface mass (lightweight partitions or panels in various materials)
  • Airborne noise insulation in ceilings
  • Reduction of impact noise level in all types of frames works, in formation of floating floors
  • Damping of impact noise produced by atmospheric agents in metal roofs
  • In combination with sound-absorbent materials, it results in products with high acoustic performance characteristics
  • Its application in the industrial sector range from soundproofing booths to insulation of machine rooms, drainpipes, acoustic damping of metal sheeting etc.,
  • Specially for plaster sheet measurements


  • High acoustic insulation, combined with flexion-pliable elements
  • Flexible
  • High elongation capacity
  • Easy to handle and adaptable to uneven surfaces
  • Hot and cold resistant
  • Excellent adherence on all kinds of surfaces
  • Self-extinguishing
  • Rot-proof
