Kingspan Kooltherm offers among the most thermally efficient conductivity and thermal performance values available, which means you can minimise thickness of your insulation compared to other conventional insulations to achieve the same performance.
Kingspan Kooltherm also has exceptional fire performance characteristics. As it is a thermoset material it hardens and chars in fire situations, giving off very little smoke; unlike thermoplastics, such as polystyrene which melt, soften, and give off thick black smoke.
