Cementitious

Reliable fire protection for structural safety

Cementitious fireproofing is a proven solution trusted by contractors, architects and facility managers to safeguard a building’s structural integrity.

Superior Industrial Insulation provides expert, professional cementitious fireproofing installation for commercial, industrial and infrastructure projects. Our experienced team delivers high-performance fire protection that meets demanding code requirements and withstands real-world conditions.

What is cementitious fireproofing?

Cementitious fireproofing is a spray- or trowel-applied passive fire protection system made from a blend of cement, gypsum, vermiculite or perlite mixed with water and additives. This thick, plaster-like material forms a durable, fire-resistant coating on steel beams, columns and other structural elements. Once cured, it acts as a critical thermal barrier, delaying heat transfer and helping to prevent structural failure during a fire.

How does cementitious fireproofing work?

Cementitious proofing delivers rapid heat defense, as steel loses strength quickly in a fire, reaching critical failure at around 1,100°F (600°C). Properly applied cementitious fireproofing creates a thermal barrier by insulating the structural components. It slows rapid temperature hikes by maintaining structural integrity for one to four hours, which helps prevent collapse and supports life safety efforts such as evacuation or firefighting.

Where is cementitious fireproofing used?

Cementitious fireproofing is commonly used on the following applications:

  • Steel framing (columns, beams, decking)
  • Floor and roof assemblies
  • Concrete substrates requiring increased fire ratings
  • Infrastructure such as tunnels, refineries and petrochemical plants

Key benefits of cementitious fireproofing

There are many reasons to utilize cementitious fireproofing on your next project, including:

  • Fire Resistance: Delivers UL-listed fire ratings, typically providing one to four hours of protection.
  • Code Compliance: Meets or exceeds international building and fire code standards (IBC, ASTM E119, UL 263).
  • Cost-Effective: Lower material cost than many other fireproofing options.
  • High Coverage: Can be rapidly applied to large surface areas for efficient project delivery.
  • Versatile Application: Adheres to steel, concrete and a variety of construction materials.

Types of cementitious fireproofing

  • Low-Density: Ideal for commercial buildings because it is easier to apply, but less impact-resistant.
  • Medium and High-Density: Designed for industrial settings where durability, moisture and abrasion resistance are critical. This type of cementitious proofing is perfect for mechanical rooms, parking garages and heavy-use environments.

Maintenance and longevity

Periodic inspection of cementitious fireproofing is essential to ensure ongoing fire protection and code compliance. Damaged or missing sections should be repaired promptly to maintain the system’s effectiveness and your building’s safety.
