TOPAKUSTIK® type 28/4- Wide grooving
These grooves are the ideal solution for standard absorption requirements.
As with all center-to-center distances, the “wide” grooving also comes with grooves of 2mm, 3mm and 4mm.
Thanks to the precise tongue and groove connection, planks result in an attractive surface with a joint-free appearance, because the connecting joint matches the dimension of the grooves. The planks permit simple and flexible assembly. They can be installed by stapling to a timber batten or clamping to a T-bar with TOPAKUSTIK® clips.
