Create sound absorptive surfaces on both walls and ceilings with the beauty of wood. Easy to install tongue and groove wood planking.
Alto is a perforated wood planking system which allows the designer to select from a variety of natural hardwood finishes that are acoustically transparent. The planks’ tongue and groove edges fit together to create a visually monolithic surface. The planks are 7-9/16" (192 mm) wide and 96" (2438 mm) or 120" (3048 mm) in length. The facing has parallel grooves 5/16" (8 mm) on center that match up with perforations in the core material. This creates the acoustical transparency. The veneer natural wood finish is laminated to a medium density fiberboard (MDF).
Use where reduced sound reverberation and improved acoustics are desired in a space. Meet acoustic goals with the beauty and durability of natural hardwood.
Description
An acoustical wood planking system for creating natural wood finishes on walls or ceilings that control reverberant sound energy. Planks have tongue and groove edges for blind nailing to furring strips over an acoustical core material.
Composition
Planks are made with an MDF core with hardwood veneer laminated to the face. The planks are 3/4" (19 mm) thick, 7-9/16" (192 mm) wide and 96" (2438 mm) or 120" (3048 mm) in length. The acoustical core behind the planking is typically 1" (25 mm) or 2" (50 mm) thick fiberglass.
