挤塑板(XPS)是通过加热挤塑而制成的硬质泡沫材料。相对于EPS，XPS具有强度较高、导热系数较小、隔汽性能较好、吸水性低等优点。30mm厚的XPS保温板，其效果相当于50mm厚EPS聚苯板，120mm厚水泥珍珠岩。挤塑板XPS的性能优于EPS聚苯板，但价格也高出1倍以上,其施工工艺与EPS聚苯板基本相同。
The extruded board (XPS) is a hard foam made by extrusion and extrusion. Compared with EPS, XPS has the advantages of high strength, low thermal conductivity, better gas isolation and low water absorption. 30mm thick XPS insulation board, its effect is equivalent to 50mm thick EPS polystyrene board, 120mm thick cement perlite. The performance of the extruded plate XPS is better than that of EPS polystyrene board, but the price is more than 1 times higher. The construction technology is basically the same as that of the EPS polystyrene board.
