How does charring affect panels?
Our real fire case studies refer to charring - but what is it and how does it help protect against fire spread?
Thermoplastic materials, such as polyethylene, melt and drip when exposed to heat. Kingspan's high-performance PIR and QuadCore® insulation materials, however, are thermosetting. They char when exposed to heat and self-extinguish when the fire source is removed.
