Kinetics Model KNM Loaded Limp Mass Barrier Materials are used for enclosing noise sources, either draped around equipment, suspended between equipment and quiet areas, or lagged to the equipment casing. KNM Vinyl Barrier Materials can be used effectively to lag piping systems, reducing valves, etc., and are highly effective as crosstalk barriers and septums. Our vinyl barrier materials are available in 1/2 psf to 1 psf (2.5 to 4.9 kg/m2 ) surface weight, in 54" wide x 20 yard (1372 mm x 18.2 m) rolls, with acoustical ratings of STC-21 to STC-26.
Kinetics Model KNM-C Clearview Noise Barriers are transparent, limp, heavy PVC and are recommended for use in applications where it is necessary to maintain visual contact with noisy equipment, yet achieve a high degree of noise reduction. KNM-C materials are available in 48" wide by 20 yard (1219 mm x 18.2 m) rolls with acoustical ratings of STC-21 and STC-26.
