XPS insulation stands for what material?

Explanation:
XPS insulation stands for extruded polystyrene. The X signals the extrusion manufacturing process that forms a continuous closed‑cell foam, producing a uniform, dense material with low water absorption and high compressive strength. This makes XPS more moisture resistant and dimensionally stable than Expanded Polystyrene, which is made by expanding and fusing polystyrene beads and tends to have a more open-cell structure. The other names listed aren’t the standard term for this material.
