ARO Plank 1

ARO Plank is a wall system composed of modular planks that assemble to create customizable patterns, yielding a continuous, acoustically absorptive architectural finish. ARO Plank 1 has six distinct half round modules that are composed of felt-covered acoustic substrate available in eight standard patterns. Got your own ideas? This clever acoustic system allows one-of-a-kind patterning by switching up plank widths and over ninety colors of pure wool felt. Plus, installation is a breeze with FilzFelt’s Interlock Mounting System.

The ARO Collection is an Interior Design HiP Performance Wonder award winner.

  • Durability Contract
  • Maintenance Vacuum occasionally to remove general air-borne debris. Should soiling occur, spot clean with mild soap and lukewarm water. Avoid aggressive rubbing as this can continue the felting process and change the surface appearance of the felt. Refer to 100% Wool Design Felt Maintenance + Cleaning for detailed care instructions.
  • Lead Time Made to order and certain lead times will apply
  • Environmental 100% Wool Design Felt contains no formaldehyde, 100% biodegradable, 100% VOC free, no chemical irritants, and free of harmful substances
  • Acoustic Substrate is 100% recyclable
  • 100% Wool Design Felt contributes to LEED©
  • Installation Installs with Interlock Mounting System provided (wall fasteners not included)
  • Variation Wool felt is a natural material and color variation and inclusions of natural fiber on the surface are evidence of the 100% natural origin of the material. Product color is only indicative, as it is not possible to assure consistency of color in a natural product due to the natural color of raw wool and absorption of dyes. Color matching cannot be guaranteed on shipments and variation will be more pronounced beyond the normal commercial range.
  • Custom Custom patterns may be specified
