Fire Rated Gypsum Board

Fire-rated gypsum board is a form of drywall that helps prevent the spread of flames across a home or business. Gypsum is approximately 21% chemically combined water, which greatly contributes to its effectiveness as a fire-resistive barrier. When gypsum drywall is exposed to fire, the water is slowly released as steam, effectively slowing heat transmission. This gypsum is used to develop fire-resistant drywall.  

Fire-rated gypsum drywall is more fire-resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to fire exposure.
