The Whisperwave® Ribbon Sound Baffle allows you to unleash your creativity while reducing noise and reverberation. Add dimension and acoustical control right where you need it the most with Whisperwave® Ribbons. Suspend Whisperwave Ribbons from ceiling-mounted cables using supplied corkscrew hangers. They may be hung as high or as low as necessary to avoid obstacles in the ceiling, work around HVAC or to achieve a particular design.

Made from Class 1 fire-rated melamine foam, Whisperwave® products are offered in standard and custom sizes and curve patterns. Whisperwave® products are lightweight and easy to install. Whisperwave® products are available in natural grey, natural white or may be HPC Coated to add color and additional protection (see HPC color chart.)

Installation Method:

  • Install the included corkscrew hangers in the field for ceiling-mounted cable installation (cable and cable mounts provided by installer)
  • Avoid hanging baffles more than 10 feet below the ceiling, as long tethering will cause them to sway in air currents.
  • For best results, install this product at the end of your construction project.
  • Use clean gloves to prevent soiling material.
  • Melamine foam is fragile, please handle with care.
  • Do not install material of unacceptable quality.

What is HPC Coating?

HPC is a high performance coating that is applied to acoustical melamine foam base. Our exclusive water based HPC formulation improves durability and protects the acoustical foam from dust and dirt, allowing the surface to be cleaned using a damp cloth. The HPC coating is especially appropriate for use high-traffic areas. HPC Premium extends the HPC coating further by offering a line of brilliant colors from which to choose.
