Lightweight reusable Structural EPS Cement Sandwich panel For decoration
1. Description:
EPS & Cement Sandwich panel is a kind of lightweight energy saving wall material, which uses cement calcium silicate or fiber reinforced calcium silicate board as face panel, filled with cement, EPS polystyrene foam particles, and as core material and forming by one time compound.
It can be widely used in all kinds of decoration and building construction, it's one of the best
