MCM Acoustical’s Grooved Sandwich Panel offers strong built-in acoustical absorption while providing the beauty and warmth of natural wood veneer. The double layers of v-grooving on the face of the panel channel sound to the no-added urea formaldehyde fiberglass core where it is absorbed.
The Grooved Sandwich Panel can be manufactured to the desired size, with shop drawings produced by MCM Acoustical, thereby requiring no field cutting for faster installation. The Panels are available in three thicknesses: 1 1/8” (28mm), 1 3/8” (35mm) and 2 3/8” (60mm). The standard groove spacings are 3/16” (5mm), 3/8” (10mm) 5/8” (15mm) and 13/16” (20mm) but custom spacing is also available.
The Grooved Sandwich Panel can be customized in a variety of wood veneers. MCM Acoustical lays-up its own veneer so slip-matched, book-matched, random or custom matched lay-up choices are available.
The Panels can be finished in standard clear lacquer or can be custom stained to match a control sample. The Grooved Sandwich Panel can also be painted.
The Grooved Wood Planks are Class A Fire-Rated interior wood finish products as per ASTM E84 and CAN/ULC S102, and are tested in an accredited NVLAP test facility as a finished composite product using Class A individual components.
The grooved veneer surface, perforated core material, and black fiberglass mat at the rear combine to create a substantial acoustic performance of up to NRC of 0.95 enhanced by introducing an extra layer of sound absorptive fiberglass as a substrate material.
Like any other architectural natural wood product, the Grooved Wood Planks are to be acclimatized inside a controlled interior environment for at least 72 hours before installation. During storage, prior to installation, during installation, and after installation the relative humidity level of 35%-55% and a temperature range of 20°-27°C (68°-81°F) must be maintained.
