EPS cement-covered sandwich panel 1,convenient construction 2,save in labor cost and construction period EPS cement-covered sandwich panelShort introduction:The expanded polystyrene(EPS) board is the main structure material of this product,and the two sides covered with surface mortar and alkali-resistant fiberglass mesh.It is of thermal insulation, heat insulation, sound insulation, fire protection and decorative features. The surface mortar layer enhanced by alkali-resistant fiberglass mesh strengthen the whole board, and can prevent cracking. Features:1,it can be cut and installed according to size and shape, with convenient construction2,it can be prefabricated by factory so that greatly saved in labor and construction period3,widely used in decoration and partition of interior and exterior wall Technical performance:1)Expanded polystyrene board mail technical performance
