A concrete panel with an absorptive layer with different stage of absoption can be also designed in various colours. These panels are tested by a long period of time, and they are frequently used with respect to the character of the material in highly stressed environment.

Double-layered concrete panels consist of sound-proof plate, which also performs the structural functions and the absorption layer of the profiled, lightweight Liapor-concrete aggregate. Both layers are connected at the factory using the “fresh to fresh” method and form a monolithic unit.

The panel is produced as a bearing reinforced concrete panel with a layer of absorptive material (one or both-sided).
