The Kingspan GreenGuard XPS Extruded Polystyrene Insulation Board is designed for professional builders and DIY enthusiasts seeking a high-performance thermal barrier for demanding applications like floors, basements, and inverted roofs. Its standout feature is its impressive 300kPa compressive strength, which allows it to withstand significant weight from concrete slabs or paving without compromising its insulating properties. While its rigid design ensures long-term durability and resistance to moisture, users should note that the board requires precise cutting to achieve a seamless fit for optimal thermal efficiency.

Use a straight edge to guide your insulation knife to ensure perfectly square cuts before butting boards together.
Ensure you are using a sharp blade; a dull blade will tear the foam structure rather than slicing it cleanly.
To install, ensure the substrate is level and debris-free. The boards are easily cut using a fine-toothed saw or a sharp insulation knife. When laying, ensure boards are tightly butted together to maintain a continuous thermal layer and eliminate potential thermal bridges. The boards are compatible with most standard concrete, screed, and paving systems. For long-term performance, store the packs off the ground in a dry, covered area to prevent environmental contamination before use.
