The panels can be configured with sound absorbing foam on both sides of the barrier to assist in decoupling the barrier from a vibrating, sound transmitting surface or on one side only for adding mass and sound absorption to a light gage equipment housing. Depending upon the application, the SonoCon acoustical foams and foam barrier composites are offered with protective facings which prevent contamination from the immediate environment. Selection of the facings range from thin polyethylene films to rugged plastic or vinyl surfaces suitable for sound isolating floor mats or tractor or truck headliners to perforated wear surfaces to aluminized membranes. Panels can be attached using conventional compatible adhesives or pressure sensitive adhesives though mechanical fasteners are recommended for larger panels. Since most applications are unique, please contact PHOENIX-E for assistance is selecting a particular foam-barrier system. Acoustical Performance of the faced foam and foam barrier composites Sound transmission class ratings range from STC 20 to STC 26.depending upon the weight of the barrier. Noise reduction coefficient ratings range from 0.31 to 0.90 depending upon the foam thickness.
