Clever Chemistry!

Sucraseal is manufactured using the latest chemistry advancement to achieve excellent performance against fire. Utilising sucrose as a key ingredient in the formulation, when the intensity of a flame attempts to burn through Sucraseal, a protective crust forms. Despite the intensity of the fire, sucrose crystals work to extinguish the fire and prevent flame spread across the surface. The only British Class 1 fire-rated Open-cell foam (uncoated), Sucraseal is protected by a worldwide patent, making it exclusive to ThermoFoam in the UK.
