The panel is formed by 2 surface boards filling eith the mixture of polystyrene and cement in the middle. Its surface board is made by a Special form of white cement and fibre glass, which makes it heat resistant, waterproof, has optimal feature against hit and impact, and has high intensity.

The surface boards of wall panel with thickness of 3.5mm – 5mm ( which substituting the plastering of brick –laying wall ), undertaking shock and impact from outside, hence stronger the panel wall itself, and because of its special 3-in-1 composition, it also prevents the panel from distortion.

The use of polystyrene in filling od the panel reduces the weight of panel, and makes it heat insulation, sound insulation, waterproof and longer durability. The characteristic of polystyrene also keeps the panel away from decompose, moldy and insects. When these polystyrene combines with cement and distributed inside the fillings of the panel, the cement around them automate forms the shape of alveolus, which it spreads out pressures of hit and impact from outside and easy to be spiked, nail in and carrying hanging weight.
