Types of Fireproofing – From Cementitious to Intumescent Coatings

Types of fireproofing

When it comes to protecting commercial and industrial buildings, understanding the types of fireproofing available is critical. We work with general contractors, developers, and property owners every day who need reliable fire protection that meets code, performs under extreme conditions, and fits their project goals. At Sharp NC Group, we specialize in proven commercial fireproofing systems designed to protect structural steel, improve building safety, and support long-term performance. If you’re planning a project and need expert guidance, call us today at 336-760-0703 to speak directly with our team.

What Is Fireproofing and Why It Matters

Fireproofing is a key component of passive fire protection methods used in modern construction. Rather than actively suppressing a fire, fireproofing works by slowing the spread of heat and protecting structural elements—especially steel—from reaching critical failure temperatures.

Steel can lose strength rapidly in a fire. That’s why fireproofing materials for steel are required in many commercial, industrial, and multifamily buildings. Properly applied fireproofing helps maintain structural integrity, provides occupants with more time to evacuate, and supports compliance with local and national building codes.

Cementitious Fireproofing Explained

Cementitious fireproofing is one of the most widely used fireproofing solutions in commercial construction. This material is typically spray-applied and forms a durable, fire-resistant barrier around structural steel and decking.

We often recommend cementitious systems for:

  • Concealed steel

  • Large commercial buildings

  • Industrial facilities

  • Parking structures

The benefits include cost-effectiveness, high fire-resistance ratings, and proven performance. As a form of spray-applied fireproofing, cementitious materials are ideal for projects where aesthetics are less critical but durability and compliance are essential.

Intumescent Fireproofing Coatings Explained

Intumescent fireproofing coatings offer a different approach. These coatings expand when exposed to heat, creating an insulating char that protects steel during a fire. Intumescent systems are commonly used when architectural appearance matters.

We frequently install intumescent coatings in:

  • Office buildings

  • Lobbies and public spaces

  • Areas with exposed structural steel

This solution provides a smooth, paint-like finish while delivering strong fire protection. While intumescent systems typically cost more than cementitious options, they are often the best choice for visible steel in fireproofing for commercial buildings where design is a priority.

Spray-Applied Fireproofing: A Versatile Solution

Spray-applied fireproofing includes both cementitious and fiber-based materials applied directly to steel and decking. These systems are efficient for large-scale projects and allow us to achieve consistent coverage and required thickness across complex structures.

Spray-applied fireproofing is commonly used in:

  • Warehouses

  • Manufacturing facilities

  • Distribution centers

Proper application is critical. Our trained crews ensure adhesion, uniform thickness, and compliance with specifications—details that directly affect performance during a fire.

Spray-Applied Insulation: Fire Protection Plus Performance

In addition to fireproofing, we also install spray-applied insulation systems that enhance building performance. While insulation is not the same as fireproofing, it can complement fire protection by improving thermal efficiency, reducing condensation, and providing acoustic benefits.

Spray-applied insulation is often used in commercial and industrial spaces where energy efficiency and moisture control are important. When coordinated correctly, insulation and fireproofing systems work together to support safer, more efficient buildings.

Types of Fireproofing Compared: Cementitious vs. Intumescent

Understanding the differences between systems helps determine the right solution for your project. When comparing cementitious and intumescent options, we consider:

  • Fire rating requirements

  • Exposed versus concealed steel

  • Budget and schedule

  • Environmental conditions

Both systems play an important role in fireproofing for commercial buildings, and choosing the right one requires experience and technical knowledge. That’s where we come in.
