Primacoustic Stratus is a broadband absorber designed to be suspended above the listening position to control primary reflections.

The Stratus Cloud kit consists of a Primacoustic 24” x 48” Broadway panel and aluminum hardware for overhead suspension. The absorptive panel is made from 6 lbs. per cubic foot high-density encapsulated fiberglass. The aluminum hardware clamps onto the panel sides and provides four points to hang from.

The science is based on thermo-dynamic energy transfer, where sound penetrating the Stratus Cloud causes the glass fibers to vibrate which in turn, converts the acoustic energy into heat.

The Stratus Cloud kit ships flat and final assemble is performed by the end user. A screwdriver is the only tool required for assembly. Each kit contains the absorptive panel, aluminum side clamps and cross-bars. Assembly takes about 15 minutes from start to finish!

Test data provided by Bodycote Materials Testing Inc. This method, designated as ASTM E 84-05, "Standard Method of Test for Surface Burning Characteristics of Building Materials", is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire-hazard or fire-risk assessment of the materials, products, or assemblies under actual fire condition. Fire and burn test data applies to the Broadway acoustic panel only. Please consult your local building authority and/or insurance underwriter to ensure the product meets local building codes.
