This 24-pack of Broadway Acoustic Scatter Blocks Panel from Primacoustic are fabric covered acoustic panels designed to provide an acoustic treatment where you want to control primary reflections, eliminate flutter echo, and reduce standing waves. The panels are made from high density 6 lb per cubic foot glass wool. Each panel is fully encapsulated with micromesh and the edges are resin hardened to assure safe handling during installation. The bevelled edge panels are covered in an acoustically transparent fabric. The Broadway panels are laboratory tested for acoustic performance and Class-A/I fire safety by meeting ASTM-E84 and Can-UL S102 requirements for flame spread and smoke development.
