Kingspan GreenGuard® PB4 Protection Board comprises closed–cell extruded polystyrene (XPS) with tough plastic capsheets on both sides. It is configured in a convenient 4 ft x 50 ft bundle. Its tough plastic capsheets resist puncturing and its high compressive strength and impact resistance withstand even the toughest load pressures. Because it is made of extruded polystyrene (XPS), Kingspan GreenGuard® PB4 Protection Board has a dense, closed–cell construction that resists both moisture absorption and decomposition from long–term exposure to chemicals in the soil.
