Theo sandwich wall panel is a new kind of lightweight energy saving building materials,
composited by EPS( polystyrene foam particles), Portland cement and sand as core materials, 4.5mm thickness calcium silicate board as surface panel on both sides.
Because of its excellent performance , our wall panel becomes popular and popular, widely used in modern fabricated buildin, such as villa, apartment, hotel, KTV, office etc and reforming old partition walls in recent years.
