The element consists of horizontal upper and lower belts that are held by vertical boards on the left and right. Vertical half-logs are attached to belts at the sound side, with a diameter of 55 mm, at a center distance of 11 cm. The wall to be covered with wood panels is at the back. Anti-vandalism protection consisting of black, robust plastic mesh is placed behind the logs. 40 mm thick insulation mat with black glass fleece is then attached. It prevents water from entering the mat. An air gap is created between the insulation mat and the wall. It increases noise protection, and provides the required ventilation. If required, additional middle belts are installed.
Wall element, highly absorbent on one side, with airborne sound insulation of DLa = 11 dB acc. to ZTV-Lsw 6, or sound absorption group A3.
