Promasound TL is a total new, sound isolation barrier, totally free of lead and PVC. It is MED certified (Wheel mark). Promasound has a high mass, but is also extremely flexible. Therefore a very high Rw index can be reached with a relatively thin product. Compared to the traditional EPDM plates, Promasound provides a weight saving of 75% with the same Rw reduction.
Promasound is available in rolls as well as in sandwich panels.
