dBmat WM2 is a sandwich composite incorporating 2 layers of dBcloth acoustical foam and a single barrier septum. When applied to sheet metal, plastic or wood, the decoupling foam layer typically ¼”(6mm) thick isolates the barrier while the thicker absorption layer reduces airborne reverberant noise.
Key Benefits
- Proprietary manufacturing process ensures permanent bonding between foam and vinyl barrier material
- Can be formulated to provide maximum noise reduction in the harshest environment by adding various facings or embossed surfaces
- Available in a wide range of weights, thickness and as sheets or rolls
- UL94 V0 barrier available
