EPS Board vs XPS Board: 2026 Spec Cut for Insulation Selection
XPS and EPS are both closed-cell polystyrene foam boards for building insulation, but XPS delivers roughly 0.028-0.030 W/(m·K) thermal conductivity versus EPS at 0.038-0.041 W/(m·K), with XPS compressive strength typically 200-250 kPa against EPS below 100 kPa at 18-20 kg/m³ density.
