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 suggested 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.

Durability Contract or residential
Lead Time Made to order and certain lead times will apply
Installation Planks install with Interlock Mounting System provided (wall fasteners not included)
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.
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 between individual planks and expect color variation beyond the normal commercial range.
Environmental 100% Wool Design Felt is 100% biodegradable/compostable and Acoustic Substrate is 100% recyclable
Contains no formaldehyde, 100% VOC free, no chemical irritants, and free of harmful substances
100% Wool Design Felt contributes to LEED©
