EPiC database - Polystyrene (EPS/XPS) insulation

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Polystyrene (PS) is a synthetic polymer and thermoplastic. Polystyrene insulation is made from Expanded (EPS) or Extruded Polystyrene (XPS). It has a low thermal conductivity (0.03-0.038 W/(m·K)) and is a lightweight material.PS insulation is made by polymerising styrene monomers in polystyrene before moulding it (EPS) or extruding it (XPS) into rigid foam panels.PS insulation is widely used in the construction industry. EPS is used in walls and on roofs that do not require stepping onto. XPS, with its increased compressive strengths, can be stepped upon and is therefore more common on roofs.

本材料为免费环境性能在建筑领域（EPiC）数据库的一部分。EPiC数据库包含250种以上建筑材料的固有环境流动系数，采用全面混合生命周期清单方法。聚苯乙烯（PS）是一种合成聚合物和热塑性塑料。聚苯乙烯隔热材料由发泡聚苯乙烯（EPS）或挤塑聚苯乙烯（XPS）制成。其具有低热导率（0.03-0.038 W/(m·K)）且为轻质材料。PS隔热材料通过在聚苯乙烯中聚合苯乙烯单体，在模具成型（EPS）或挤塑成型（XPS）为刚性泡沫板前制成。PS隔热材料在建筑行业中得到广泛应用。EPS用于无需踩踏的墙壁和屋顶。XPS因其较高的抗压强度，可承受踩踏，因此在屋顶的使用更为普遍。
