Hollow Panel (KPB) is a kind of light weight energy saving wall material made from cement, EPS polystyrene foam and fly ash, without face panel, the hole takes 36% in cubage. It can widely be applied to wall materials of various high and low buildings such as: bank, office building, hospital, school, hotel, shopping mall, amusement hall, old house reconstruction, residence and workshop.
Composition: made from cement, EPS polystyrene foam and fly ash, without face panel, the hole takes 36% in cubage.
Size(L*W*T): 1500-3000mm * 600mm* (90,120,150mm)
Usage: Interior and exterior partition on steel or concrete structure building ,for new construction, additions or renovations.
Advantages: Light weight, sound insulation,heat insulation and preservation, water proof, fire proof, fast construction, save space and so on.
