It’s important to understand the burning behaviour of building materials and to what extent, once exposed to fire, they will contribute to fire propagation.
Kingspan’s high-performance PIR, QuadCore® and Kooltherm insulation materials are thermosetting, typically resulting in a protective stable char layer when exposed to heat.
This char layer acts as a barrier between the fire source and the insulation underneath. When the fire source is removed the insulation self-extinguishes and does not contribute to fire spread.
