CETRIS® AKUSTIC
Cement bonded particleboard CETRIS® AKUSTIC is a board made by processing (drilling regularly spaced holes) of the CETRIS® BASIC board type.
In addition to the existing high mechanical parameters, such treatment improves the noise transmission properties. If the plain – basic board CETRIS® shows exceptionally high sound transmission loss, the drilled boards is an absorbent acoustic cladding element.
In comparison to other acoustic cladding materials using of cement bonded particleboards CETRIS® AKUSTIC in addition assures resistance to mechanical breaking and to humidity – all with simultaneous high flame reaction class (A2 -s1,d0). These parameters predestine the new CETRIS® board type for use as absorbing acoustic cladding mainly to sporting facilities, rooms with variable temperature and humidity and buildings with special requirements.
