Timberwool™ Wood Fiber Acoustic Panels (24" x 96")

Timberwool absorbs airborne sound to reduce echo and reverb inside a room. A 1" panel is rated NRC 0.45 and a 2" panel NRC 0.75, and a 2" panel over a CelluZorbe backer reaches NRC 0.90 or higher.

Yes, Timberwool is Class A rated under ASTM E84, the top building classification for surface burning. It also passes the NFPA 286 room corner fire test.

Our standard panels are 24" x 96" (16 sq ft) and 24" x 48" (8 sq ft), and we can do any panel size up to 24" x 96". The standard panels are 1" or 2" thickness, and can be made in 5/8" and 1-3/8" thicknesses.

Yes, Timberwool can be ordered in a range of sizes, thicknesses, edge profiles, and finishes, and it can be cut to custom shapes. The options are below. Contact the team for free samples or a custom quote.

Yes, Timberwool is an outdoor sound absorbing panels. It is water resistant and expected to last 20 or more years outside. Re-prime any edge cut on site so the cut face keeps the same water resistance as the factory-sealed surfaces.

Timberwool is installed to walls and ceilings with screws driven into furring, plywood, hat channel, or solid structure behind the finish surface. Screw type follows the panel thickness and substrate. See our Timberwool install guide for specifics.

Yes, Timberwool ships primed and ready for paint. Spray non-diluted latex paint with an HVLP or airless sprayer, working from several directions so the paint settles into the wood fibers for even color. A second coat is fine and does not reduce sound absorption. Rolling and brushing are not recommended, since they leave paint sitting on the surface. Read our Timberwool Field Painting Guide for more details. We can also paint the panels for you: Timberwool Painted Acoustic Panels.

Timberwool is a cementitious wood wool panel: strands of real wood fiber bound together with Portland cement and water, then pressed into a rigid board. The wood gives it a natural texture and lets it be cut and screwed like lumber, while the cement makes it Class A fire rated, moisture resistant, and mold resistant.

Timberwool cuts with standard woodworking tools: a table saw, circular saw, router, jigsaw, or hand saw all work. If installed outdoors, reprime any exposed edges so it keeps the same moisture resistance as the factory-sealed faces.

No, Timberwool works mounted directly to the wall or ceiling. You can raise its absorption, especially at low frequencies, by mounting over furring strips for a 3/4" air gap, or by running a deeper 1" to 2" cavity and adding a CelluZorbe or EcoVerb Roll backer behind the panel. A 1" panel rated NRC 0.45 direct-mounted reaches NRC 0.80 with a 1" CelluZorbe backer.

Yes, in a 1", 1-3/8", or 2" thickness. Baffle hanging uses a PVC tube epoxied into the panel, spaced no more than 24" o.c., which works out to 3 points on a 24" x 48" panel and 5 points on a 24" x 96" panel. Baffles come primed white or painted on both faces. Reach out for a quote on a Timberwool baffle order.

Timberwool always ships primed and ready to finish, in Primed Clear or Primed White. The factory primer is what keeps the panel's fire, moisture, and mold resistance and lets paint go on evenly.

Timberwool and Tectum are very similar wood wool panels, and we regularly help customers use Timberwool on projects originally specified with Tectum. If you have a spec that calls out Tectum, or you need more detail or a custom size to make the substitution work, reach out and the team can help.
