Stratus Details and Specifications

The Primacoustic Stratus is an acoustic cloud system designed to create large acoustic ceilings by linking multiple units together with a rigid frame.

Test data shows the suspended Stratus cloud to be very effective at absorbing sound from 100Hz and up. This is achieved by a combination of the two inch glass wool panel and the air space formed behind the panel when suspended

The Stratus will absorb the powerful primary reflections that bounce off room boundaries as well as flutter echoes between the ceiling and floor. The fabric face and aluminum channels will look great above your listening position for years to come.

The Stratus includes all mounting hardware and may be installed in one of two ways. Suspended installation uses tie-wire to hang the cloud. Flush installation attaches the Stratus directly to the ceiling. Which method you use will depend on the ceiling height and layout of your room. Either way, everything you need is in the box for fast and easy installation.

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.
