Tecsound® is a high-density, polymer-based asphalt-free synthetic soundproofing membrane, which is viscoelastic and highly adaptable, and provides good acoustic insulation in the different construction elements without increasing thickness. 


  • Airborne noise insulation in vertical surfaces with low surface mass (lightweight partitions or panels in various materials)
  • Airborne noise insulation in ceilings and roofs
  • Reduction of impact noise level in all types of frameworks, information of floating floors
  • Damping of impact noise produced by atmospheric agents in metals roofs  
  • In combination with sound-absorbent materials, it results in products with high acoustic performance characteristics
  • Its applications in the industrial sector range from soundproofing booths to insulation of machine rooms, drainpipes, acoustic damping of metal sheets etc.,


  • High acoustic insulation, combined with flexion-pliable elements (sheet plaster, carrier board)
  • Flexible
  • High elongation capacity
  • Easy to handle and adaptable to uneven surfaces
  • Hot and cold-resistant
  • Self-extinguishing
  • Excellent ageing-resistance
  • Rot-proof
