Primacoustic Nimbus Data Sheet

niMBus

The Nimbus™ is an easy to use 24” x 48” x 1.5” (610mm x 1219mm x
38mm) acoustic cloud kit designed to attenuate ambient noise and

control low, mid and high frequency reections. The Nimbus is generally

placed above an area where a reduction in sound level is desired such as
restaurant tables, library reading zones or boardrooms.

When installed the Nimbus delivers greater intimacy and improved
intelligibility in any space. Each Nimbus kit includes a fabric covered
Broadway panel, SlipNot™, Helix™ and all hardware required to attach
to a ceiling. The Nimbus is available in black, beige or grey fabric or in

Absolute White™ paintable nish.
