Slotted Acoustic Wood Planks

Wood is generally accepted as a desirable surface treatment in general architectural spaces, as well as critical listening and performance spaces. However, one of the problems of wood is that the flat surfaces can cause unwanted reflections which can negatively colour sound and cause problems with speech intelligibility.

Traditional acoustic treatments such as fabric wrapped fiberglass, expanded mesh and acoustic plasters are all very effective but none offer the architect the look and feel of real wood veneers.  Slotted Acoustic Wood Planks - Wood Acoustic - from RPG Europe are now available, and provide absorption, aesthetic appeal and the natural beauty of wood for the architects and designers.

alpha planks are to be installed to a wood or metal subconstruction.
The distance between battens perpendicular to the length of the panels must not exceed 600mm. alpha planks are prepared with tongue and groove edges that provide an integral air space of 1/10 mm on the back side of each plank. Please ensure that the installation nails go through the backside of the groove and not the tongue.

The panels can be cut to size with any common woodworking tools. If field cutting, make sure the visible surface lies upwards while working with the material to prevent surface scratches.
