Spray Fire Resistive Material
Fireproofing
Spray Fire Resistive Material
Spray Fire Resistive Material (SFRM) is one of the most widely specified passive fire protection systems used in commercial and industrial construction. Designed to protect structural steel during a fire, SFRM helps buildings maintain their structural integrity by delaying the effects of extreme heat, providing valuable time for occupant evacuation and emergency response. At Apex Building Company, we install certified Spray Fire Resistive Material systems for commercial projects throughout the Southeastern and Southwestern United States.
Our experienced, in-house installation teams work with general contractors, architects, engineers, and developers to ensure every SFRM application meets project specifications, manufacturer requirements, and applicable building codes. Whether your project involves a healthcare facility, office building, warehouse, manufacturing plant, educational campus, or high-rise development, Apex delivers dependable fireproofing solutions backed by quality workmanship and a commitment to safety.
What Is Spray Fire Resistive Material
Terminology
Spray Fire Resistive Material (SFRM) is the industry-standard architectural term used in commercial construction documents and project specification manuals to describe spray-applied fireproofing systems.
Specification
Most commercial building specifications include a dedicated section for SFRM, commonly identified as Specification Section 07 81 00, which outlines the required materials, application methods, and performance standards for the project.
Application
SFRM consists of a dry, bagged material that is mixed with water at a precise ratio before being sprayed under pressure onto structural building components. Once applied and properly cured, the material forms an insulating layer that protects structural steel from the extreme temperatures generated during a fire.
Thickness
The thickness of the installed material is determined by the fire-resistance rating required for the building and is verified through testing performed by certified agencies.
Fire Ratings & Code Compliance
One of the primary functions of Spray Fire Resistive Material is to provide a tested and certified level of fire resistance for structural components. Depending on the design of the building and project specifications, SFRM systems are installed to achieve specific hourly fire ratings. These ratings are based on standardized testing conducted by recognized independent testing laboratories. The required thickness of the SFRM material is determined by the tested assembly, the structural steel member being protected, and the fire-resistance rating specified by the project’s architect or engineer. Because proper installation directly impacts fire performance, SFRM applications must follow strict manufacturer guidelines and project specifications to ensure compliance with building codes and design requirements.
Fire Rating
2-Hour
Provides up to two hours of fire resistance, offering enhanced protection for critical structural elements and supporting building safety requirements.
Fire Rating
3-Hour
Provides up to three hours of fire resistance for applications requiring the highest level of protection, helping maintain structural integrity during prolonged fire exposure.
