XPS (Extruded Polystyrene) foam core is a rigid insulation board manufactured through a continuous extrusion process. This process creates a uniform, closed-cell structure with high density and strength. Its key advantages over EPS (Expanded Polystyrene) are its superior moisture resistance, higher compressive strength (ranging from 150 to 500+ kPa), and lower thermal conductivity (higher R-value per inch). While EPS is made by expanding beads, which can leave microscopic channels, XPS’s extruded structure provides a consistent barrier against water vapor and air infiltration. This makes XPS the preferred choice for below-grade applications (foundations, basements), inverted roofs, floor heating, and any scenario where moisture exposure or high load-bearing capacity is a concern.
