In residential homes, installation of fire rated drywall is required by state and local building codes on interior and exterior walls near furnaces and utility rooms. Fire rated drywall can also be installed in a basement or other places where a wood stove might be used or around the opening of a fireplace. Fire rated drywall is typically found on garage walls and ceilings that are adjacent to the main living area of the home.
For commercial buildings, fire rated gypsum drywall is specified for most of the building walls and ceilings to meet building code requirements for fire partitions and assemblies. These fire rated partitions and assemblies provide life safety for the buildings occupants.
