Thick, sound-softening wool felt and natural cork composite come together in Index Linear—a seamless, plank-style wall covering that adds linear emphasis to any space. As a vertical installation, Index Linear runs continuously from the floor to ceiling in heights up to 9’-0” (2.7 m). In a horizontal format, choose lengths up to 9’-0” (2.7 m). Planks are available in 2 in (5 cm), 4 in (10.2 cm), 6 in (15.2 cm), 8 in (20.3 cm), 10 in (25.4 cm), and 12 in (30.5 cm) widths and sold in either 3mm or 5mm felt thickness. Each order includes equal numbers of six pattern elements that install easily with heavy-duty wallcovering adhesive.

Installation Each order is equally divided into six different tile heights: 2”, 4”, 6”, 8”, 10” and  12” (5 cm, 10.2 cm, 15.2 cm, 20.3 cm, 25.4 cm, and 30.5 cm). 50% will be 1/4 in (8 mm) thick tiles and 50% will be 5/16 in (8 mm) thick tiles. This is to encourage a random, rather than symmetrical patterned effect to the installation. Tiles attach to a wall surface using a heavy-duty wallcovering adhesive. Tiles will be oversized by 2 in (5 cm) in length to accommodate field conditions and may be trimmed to size with a utility knife. Refer to installation instructions for complete guidance.
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 tiles and expect color variation beyond the normal commercial range.
Environmental 100% Wool Design Felt is 100% biodegradable/compostable and Cork Composite Backing is 93% pre-consumer recycled content
Contains no formaldehyde, low VOC, no chemical irritants, and free of harmful substances
Cork composite backing is repurposed FSC Certified cork cutoffs from bottle stopper production
