This is the house which is contructed with the EPS sandwich in the Austrican. and the house is saved more area. Sound Insulation more than 40 dB. Fireproof and water proof.Earthquake Resistance,ect. what's more, the panels can also be reuse if necessary.
1. The introduction of Economic sandwich board
Wonke Greenboard® is a kind of light weight energy saving wall material taking reinforced fiber cement board as face panel, within cement, EPS, fly ash as core material and forming by one time compound. Our product has features of light weight, high intensity, thin, water & fire proof, heat preservation, sound insulation, quakeproof, low cost and space-saving. EPS & Cement sandwich panel are widely applied to interior wall partition, exterior wall and roof for all kind of constructions. Its birth marks the wall material will appear renewal trend, instead of traditional block, the new architectural thoughts and its outstanding performance meet the requirements of modern architectural environment
