Sound absorbers

The sound-absorbing materials are characterized by the presence of open porous cells mainly applied “on sight”, they can have a flat, rusticated or pyramidal surface, or they are fibrous materials, capable of transforming sound energy into thermal energy thanks to the intrinsic absorption capacity.


  • Polyurethane foam
  • Polyurethane agglomerate
  • Polyester fiber
  • Expanded melamine
  • Rock wool
  • Fiberglass


The soundproofing materials are frequently coupled with lead sheets and plastic masses. The masses are always suspended or interposed with elastic suspensions, with the aim of improving insulation performance.


  • Plastic masses
  • Bitumen
  • Lead
  • Coupled materials
  • High density elastomers
