Fireproofing

Cementitious fireproofing is often referred to as spray applied fireproofing or SFRM for short. This coating is either gypsum or portland cement-based and is the most common form of fireproofing.

Fireproofing contractors will use specialty machinery to mix water and material. Then using compressed air, they atomize and spray apply the fireproofing to the correct thickness for the required rating. When the cementitious material completely dries, it forms a barrier. This coating will act as an insulator and significantly delay heat transfer. In the event of a fire this will protect the building structure from failure for the prescribed time.

Not all cementitious fireproofing is created equal, so you need to choose a product that is best suited for your project as well as the environmental conditions your building will encounter. Some fireproofing is more durable, and some are better suited for high-moisture areas. Some products are designed for conditioned spaces while others are tested for durability in freeze-thaw cycles.

In addition to the above, cementitious fireproofing comes in different densities which are broken down into three categories, low, medium and high density. Higher density materials will have different properties then lower density materials. Higher density materials may be required by code depending on different factors.

The cementitious products are the most common materials used for fireproofing services. It is a single component, spray applied, mill-mixed plaster designed to protect the structural foundation of the building from failing. This can be applied to concealed and exposed steel structures.
