Product Description

Whisperwave® Ceiling Cloud curved accent products allow you to unleash your creativity while reducing noise and reverberation. Add dimension and acoustical control right where you need it the most with Whisperwave® Ceiling Clouds.

Whisperwave® acoustical foam clouds are available in natural white, natural grey and HPC coated colors. The HPC coating is applied to all surfaces of the cloud. Made from Class 1 fire-rated melamine foam, Whisperwave® products are offered in standard sizes or they may also be customized for specific project requirements.

Whisperwave® Ceiling Clouds are lightweight and easy to install. Suspend these ceiling clouds using 1.5″ corkscrew hangers & cable (sold separately). The corkscrew hangers pierce and screw into the back of the foam cloud to provide an attachment point for wire or cable. Appropriate hardware to mount cables or wire to your ceiling may be purchased locally or provided by your installer.
