Extruded polystyrene (XPS) is a rigid foam insulation known for its high compressive strength, moisture resistance, and long-term durability. It’s best used below grade in foundation walls, under concrete slabs, or in roofs where insulation may be exposed to moisture or heavy loads. XPS provides a reliable thermal barrier while resisting water absorption, making it a strong choice for demanding building conditions.
