Decoupled Barrier Materials for Pipes & Ducts Noise Reduction
Barymat BM-1C is used as an external ‘wrap’ or limp barrier within structures to control noise leakage or penetration.
BM-1C is an extremely versatile noise control composite. It consists of a clear, tough polyester cover for contamination and weather resistance, a loaded flexible 1.6 lb. per sq ft. barrier for transmission loss and a 0.25 in. urethane foam decoupler. BM-1C is a very effective acoustic lagging to reduce breakout noise in pipes and ducts it can be also be used to increase transmission loss in walls and ceilings.
Barymat BM-1C effectively reduces radiated sound from a wide variety of sources.
LAG ‘FRC’ is a 1.0 lb. per sq. ft. loaded vinyl barrier with reinforced aluminum foil facing and nominal 1″ thick quilted fiberglass decoupler.
