By stacking two panels of 50% post-consumer recycled PET Sola Felt together, Hush Stack acoustical surfaces offer nearly double the sound absorption capacity compared to single Sola Felt panel applications. For even greater visual appeal, designers can select front and back layer colors from a 22-shade palette. They can also choose from 10 bevel-cut designs that reveal the back layer, with a range of natural and geometric influences, including Bauhaus, Art Deco, cubist, and contour lines, among others. The sensory-friendly felt has achieved a Red List Free Declare Label and Greenguard Gold IAQ Certification.
