Use this 3 part SimpleSpecs™ master specification to specify sprayed cementitious fireproofing and mineral fiber fireproofing for structural steel components.

Fireproofing is used to protect a building’s structural members from damage during a fire in order to provide an extended period for occupants to evacuate before collapse and to minimize fire damage to the building. The required fire protection rating is dictated by the applicable building code and is stated in hours.

The hourly rating is dependent on the size and shape of the member being fireproofed, type and thickness of the fireproofing material, location of the member within the structure, and other factors. There is no single fireproofing solution that meets all code requirements. Consult with a fireproofing manufacturer to ascertain the correct fireproofing design for each application.

Cementitious fireproofing is sometimes referred to as sprayed fireproofing. According to Underwriters Laboratories (UL) cementitious refers to how the fireproofing is applied (pumped like concrete in a slurry form with air added at the nozzle), not to the product’s ingredients.

Where fireproofing will be subject to air movement, such as in plenums without ducted air return, a sealer is required to prevent air erosion of the fireproofing.
