Every technical feature
Reliable mechanics performance: Mechanics performance of the compound wallboards is all in the head of the wallboard include it's impact resist, perch up strength, press, transverse resist. The door frame board can or buried in advance directly because of improv-ing the intensity of core bode, fix window frames of different types directly.

The good sound insulation keeps performance warm: Compound wallboard this have good sound insulation keep performance warm, alr sound insulatlon of 60mm thlck board amount greater than 40db, thermal reslstance is unique structure of wallboard and very strong resisting the ability of infiltrating. Capillary water's rise degree <20mm under the infiltrative water state. Should stiff to can be use for the bathrooms, kitchens directly.
