Fireproofing

Cementitious Spray-Applied Fire-Resistive Materials (SFRM)

Cementitious SFRM is a type of fireproofing material that is sprayed onto structural elements such as steel beams, columns, and decks. This material is composed of a mixture of cement, gypsum, and other aggregates, which provide excellent fire resistance.

Benefits of Cementitious SFRM:

• High Fire Resistance: Cementitious SFRM can withstand high temperatures, providing critical protection to structural elements during a fire.
• Cost-Effective: It is generally more affordable compared to other fireproofing methods.
• Easy Application: The spray application allows for quick and efficient coverage of large areas.
• Durability: Once applied, cementitious SFRM forms a robust protective layer that can last for many years.

Intumescent Materials

Intumescent coatings are another popular fireproofing solution. These materials expand when exposed to high temperatures, forming an insulating char layer that protects the underlying substrate from heat and flames.

Benefits of Intumescent Materials:

• Aesthetic Appeal: Intumescent coatings are often used in visible areas because they can be applied as a thin, paint-like layer that maintains the aesthetic appearance of the structure.
• Lightweight: Unlike cementitious SFRM, intumescent coatings add minimal weight to the structure.

Effective Protection: The expanding char layer provides excellent thermal insulation, significantly delaying the spread of fire.

Choosing the Right Fireproofing Solution

The choice between cementitious SFRM and intumescent materials depends on several factors, including the type of structure, budget, and aesthetic considerations. Both methods offer reliable fire protection, but understanding their unique properties can help in making an informed decision.
