Extrusion Matters: XPS vs. EPS

Extruded polystyrene (XPS) and expanded polystyrene (EPS) are both types of rigid foam plastic insulation; their different manufacturing processes produce wide-ranging performance attributes, especially in water absorption and R-value. This course discusses the negative impact of water absorption on R-value and structural integrity; explains why codes and standards are sometimes specific in requiring XPS in applications where prolonged exposure to water occurs; and concludes with a look at best specification practices for accurate bids.
