INSONOMAT is an acoustic membrane made with a base of elastomeric bitumen and recycled rubber. INSONOMAT was developed specifically for use under a layer of 1½ inch (38 mm) concrete. INSONOMAT could also be effective without concrete.

Product Properties

  • Thickness 9/16 inch
  • Underface Rubber


Install the INSONOMAT membrane with the rubber facing down. Begin INSONOMAT installation at the walls. The self-adhesive strips of the first lengths go to the wall. Apply the entire self-adhesive strip and no less than 2 in (40 mm) of the regular surface to the wall surface. Do this on all the walls and divisions in order to have a granulated surface between the walls and the concrete to be applied.
