Thermobreak® 25C is a high-performance composite acoustic wrap product developed to reduce noise from pipes, valves, fan housings and ductwork in dwellings. The flexible mass layer provides excellent sound reduction properties, and the decoupling layer breaks the vibration path between the substrate and mass barrier. The external foil facing provides a fire-resistant durable covering and an excellent surface to join adjacent sheets.
