Barymat - BTMM-14C

Noise Barrier / Absorption Composite BTMM-14C is a versatile and durable noise barrier / absorption material. The composite consists of (from top down) a metallized mylar facing that has high contamination resistance and light reflectivity, 1.0 in. of acoustic urethane foam for sound absorption, a loaded, flexible 1.6 lb. per sq. ft. barrier for transmission loss and a .25 In. urethane foam decoupler. It is suitable for very dirty, wet or oily environments and can be exposed to direct spray.

Performance Data Performance data is an extract from NRC - Ottawa report on tests according to ASTM E 90-90 with material adhered to 16 ga. steel.
