30mm Kingspan GreenGuard XPS Extruded Polystyrene Insulation 300kpa (10.5m2/Pack)

Kingspan GreenGuard XPS Extruded Polystyrene Insulation Board with a 30mm thickness and 300kPa compressive strength. A rigid, closed-cell thermal insulation material for floors, basements, and inverted roofs. Its dense cellular structure delivers long-term durability under sustained load, maintaining both mechanical strength and thermal integrity beneath concrete slabs, paving, or ballast.Resistant to water absorption, vapour transmission, and freeze/thaw cycling, it ensures consistent insulation even in demanding environmental conditions. Lightweight yet structurally stable, the boards are easy to cut and position, enabling rapid installation with precise joint alignment and no loss of compressive or thermal performance. The 30mm thickness suits overlay applications or areas where build-up depth is restricted.
