1" thick Foam Barrier Composite with Facing (10 ft. Roll)

A sandwich composite incorporating 2 layers of dBcloth acoustical foam and a single barrier septum. When applied to sheet metal, plastic, or wood, the isolation foam layer, typically 1/4" thick, decouples the barrier while the thicker absorption layer reduces airborne sound. This economical acoustical system can be formulated to provide maximum noise reduction in the harshest environment by adding various facings or embossed surfaces.

This composite is used in many engine compartments that are driving generators, pumps, hydraulics, etc. The reflective mylar face helps to reject radiant heat while the foam barrier combination gives excellent noise reduction. Several companies request dB Engineering to cut noise and thermal "kits" so that they can be quickly installed with the minimum amount of waste. Note that this manufacturer uses "mechanical fasteners" to anchor the composite to the enclosure walls and roof panels.
