Specification:
Noise Control Materials shall be a combination of limp, flexible, loaded vinyl noise barriers permanently factory-laminated to a polyester urethane absorption foam.
The limp mass barrier shall be barium sulphate loaded, unreinforced PVC material, nominally weighing 0.5 or 1.0 lbs./sq. ft. (2.5 or 4.9 kg/m2).
The bonded absorption or decoupling layer shall be 2 PCF (32 kg/m3) density, polyester urethane, flexible, acoustical foam having a Noise Reduction Coefficient (NRC) of 0.27 for 1/4" (6 mm), 0.49 for 1/2" (13 mm) and 0.73 for 1" (25 mm) thicknesses when used as a limited-length, free-hanging barrier with the foam facing the noise source.
Each composite foam shall be classed as #94HF-1 as specified by UL-94 Flame Retardancy Tests.
Composite materials shall meet the Sound Transmission Loss (STL) and Noise Reduction Coefficients (NRC) as listed.
The composites shall be furnished with (or without) pressure sensitive adhesive backing on the foam surface depending on the installation requirement, and shall be Model KC as manufactured by Kinetics Noise Control, Inc.
