Cementitious Fireproofing is gypsum based, plaster like coatings that are made to look like white stucco when dried. This method of fireproof coating is usually used to keep the steel girders below a certain temperature to avoid bending in the result of a fire, they are normally strayed on to the structural steel girder when undergoing installation. This process is also used when protecting structural concrete, vehicular tunnels for example as there is a high risk due to petrol and other intense flammable substances. Concrete structures need a high volume of fireproofing insulation to preserve their structural integrity.
Intumescent Fireproofing is more of paint based form of fireproofing usually containing sodium silicates, intumescent paints expand when heated or exposed to fire to create a heat resistant barrier. In high heat conditions or exposure to fire the paint coating thickens, forming a char layer. This provides a thick form of insulation. These paint based coatings are normally brushed or strayed onto the hazardous service that needs protecting. Intumescent fireproofing is usually used on pipes and other metallic materials like valves and tanks, putting the thick coating of cementitious fireproofing would become a safeguard.
Firestop Fireproofing is the method of sealing the openings and joints in walls and floors of the fire rated structure. Fireproofing contractors install fire dampers to fill holes and to seal the ducts where there is cross fire. Hole cuts for the purpose of pipes and electrical wiring are usually filled with a specialty fire sealant made from a gypsum or elastomeric substance.
