The composite consists of (from top down) perforated vinyl for scuff, wear and contamination resistance, 1.0 inch of acoustic polyurethane foam for sound absorption, a filled, flexible 1.6 lb. per sq. ft. barrier for transmission loss and a .25 inch poly- urethane foam decoupler layer. It is suitable for moderately dirty environments where it is not exposed to contaminants such as direct oil or water spray. |
