Nimbus Details & Specifications

The Primacoustic Nimbus is an easy to install acoustic cloud designed to be suspended over an area where a reduction in sound level is desired.

Test data shows the Nimbus cloud to be highly effective at absorbing sound throughout the vocal bandwidth from 100Hz and up. Several Nimbus clouds may be installed in an array to remove excessive echo and reverberation in large spaces.

The Nimbus consists of a Broadway high denstity glass wool panel that is effective at absorbing sound from 100Hz and up. It features hardened square edges to create clean architectural lines when installed and the durable fabric face is available in three neutral colors that work in virtually any room decor.

The included hardware set contains everything needed for most installations. Drywall anchors can be used for hollow ceiling or the eye screws may be directly fastened to a ceiling with a solid backing. Suspending the cloud is as simple as a twist of the wrist. The clever Rotofast anchor twists into the back of the high density glass wool panel and is rated at 45lbs pull-out strength. A generous amount of suspension tie wire is included. Everything you need is in the box.

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.
