Kingspan GreenGuard Insulation

Kingspan GreenGuard insulation is a rigid extruded polystyrene (XPS) board designed for high-performance insulation in below-ground and specialist applications. Known for its excellent compressive strength, moisture resistance, and durability, GreenGuard is a go-to choice for projects involving basement walls, floors, perimeter insulation, and inverted (upside-down) flat roofing systems.

These closed-cell boards are highly resistant to water absorption, making them ideal for use in damp or below-ground conditions where traditional insulation materials might degrade over time. GreenGuard boards also work well as perimeter insulation around floor slabs, helping to reduce thermal bridging and meet U-value targets in both new builds and retrofit projects.

At Insulation UK, we supply a wide range of Kingspan GreenGuard XPS insulation boards in various thicknesses and compressive strengths. Whether you’re tackling a basement, external foundation walls, or a flat roof build-up, GreenGuard offers a robust, long-lasting solution that performs even under pressure.
