What is Fire Spread?

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 thermosetting insulation self-extinguishes and does not contribute to fire spread.

The Importance of Understanding Charring Behaviour

Roy Weghorst, Head of Regulatory Affairs – Fire for the Kingspan Group, explains the importance of understanding fire spread behaviour in both large-scale system tests and real building fires, and how the charring rates we see in both allow our high performance thermosetting insulation materials to prevent fire spread.
