Membrane SilentRoll FT 75
Product Description
Membrane SilentRoll FT 75 is a combination of heavy viscoelastic mineral membrane and acoustic felt. The material has a high sound absorption coeffcient. TechnoSonus membrane layer ensures good airborne sound insulation within audible frequency range. The product is recommended for use in places where it is required to achieve maximum noise reduction values. Suitable for use in ceiling, wall, and floor frame structures.
Composition
- highly filled polymers
- organic oils
- acoustic felt
