Isobar MT050-PU8
Intended primarily as a sound barrier for cab floors. Acoustical insulation in laminated mat form consisting of a 5 Kg/m² barrier and a layer of 8 mm acoustical PU foam. Embossed black facing. Fuel, oil and water resistant. Total weight : 5 Kg/m².
Application
Isobar MT050-PU8 is designed for use as a hanging barrier or other applications where a self-supporting barrier is required. This is very high in mass and is effective in reducing noise transmission of a very broad band of frequencies, including very low frequencies. It is composed of rugged vinyl wear surface on one side of a dense PVC barrier.
