Extruded vs Expanded Polystyrene, Extrusion Matters
Course Description: This course explains the differences in structure and performance of two forms of rigid foam insulation, Extruded Polystyrene (XPS) and Expanded Polystyrene (EPS). Differences in the manufacturing processes are presented, explaining how they produce very different performance attributes, especially water absorption and R-value. The negative impact of water absorption on R-value and structural integrity is explained, providing an understanding of why codes and standards are sometimes very specific in requiring extruded polystyrene in applications where prolonged exposure to water occurs.
