GLC GypPro^™

Manufactured as a Fire Retardant Extender

Gypsum’s effectiveness as a fire retardant stems from its unique chemistry. When exposed to high temperatures, gypsum undergoes a process called dehydration, where it releases water molecules bound within its crystal structure. This released water acts as a heat sink, absorbing energy and slowing down the temperature rise of the surrounding materials. Additionally, the water vapor displaces oxygen, creating a less favorable environment for combustion. This combination of heat absorption and oxygen reduction significantly hinders the spread of flames. Thus, gypsum’s chemistry plays a crucial role in its ability to mitigate the intensity and progression of fires, making it an efficient fire retardant in various applications.
