Promasound
Promasound TL is an innovative sound insulating barrier, completely lead and PVC free. It is MED certified (wheel marking). Promasound has a high mass, but is also extremely flexible. Therefore, a very high Rw index can be achieved with a relatively thin product. Compared to traditional EPDM plates, Promasound delivers a weight saving of 75% with the same Rw reduction. It is available in rolls as well as in sandwich panels.
The main features of Promasound

- Stable with long-term use
- Fully recycle
