Kingspan GreenGuard GG300 XPS Floor Insulation Board 80mm

The Kingspan GreenGuard GG300 XPS Insulation Board is a high-performance extruded polystyrene (XPS) insulation solution designed for demanding applications where strength, moisture resistance, and long-term thermal performance are essential. Featuring a closed-cell structure, the board resists water absorption and water vapour transmission while delivering reliable insulation performance in challenging environments.

Ideal for inverted roofs, basements, car park decks, heavy-duty commercial flooring, industrial facilities, and cold storage applications, the GG300 board combines excellent thermal efficiency with outstanding compressive strength. Its lightweight construction, rebated edge design, and ease of installation make it a practical choice for both new-build and refurbishment projects.
