Keep your Light Oak Acoustic Wall Slat Panels clean and well-maintained by vacuuming or wiping them with a wrung cloth, without needing to oil them. The panels feature a sponge, felted back for sound cancellation and have a 10mm thickness. When installed directly to a solid wall, the panels have a Weighted Noise Absorption Coefficient (aw) of 0.25 and reduce noise by up to 25%. They are also moisture-proof, environmentally friendly, and 100% FSC certified. Determine the number of panels needed for your project by checking the specifications.
