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

We want, and need, building materials to prevent fire spreading from one area to another. This means it’s easier for fire professionals to deal with the fire, for people to reach safety, and for the business to keep running once the fire has been extinguished.

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 insulation materials to prevent fire spread.
