Gypsum board is a highly fire-resistant material, that can prevent fire spread, allow more time and space for evacuation.
The secret of gypsum boards’ fire resistance is in the formation of their cores which contain 21% of crystalline water. Crystalline water normally stays inside gypsum boards and does not vaporize. Temperature of gypsum boards does not heat up until all the crystalline water is steamed off and gone.
Crystalline water in gypsum boards work like fire sprinklers, creating the fire-resistance characteristic of gypsum board.
