Xinji Chaowei New Material Technology Co., Ltd. (Xinji, Hebei, China) supplies XPS extruded polystyrene boards and EcoTerra® XPS-core waterproof tile backer boards to buyers in the USA, Vietnam and worldwide.
XPS (extruded polystyrene) is a rigid foam board with a closed-cell structure. The closed cells resist water absorption and block water-vapour transmission, and the board offers low thermal conductivity – which is why XPS is widely used for insulation and as the core of waterproof tile backer boards.
Tell us your required thickness, size, quantity and destination port and we will quote FOB or CIF.


For tiling in wet areas, choose the EcoTerra® waterproof tile backer board: XPS core + alkali-resistant fibreglass mesh + polymer-modified mortar, 1220 × 2440 mm, 4–50 mm.
