Superior Fire Prevention is a certified applicator of Firefree® F88, an advanced intumescent fire protection coating designed to help protect structural components during fire events. Learn how F88 works, where it fits within your overall fire protection plan, and how the application process supports safety and compliance.
Firefree® F88 is a water-based intumescent passive fire protection coating developed and manufactured by Firefree Coatings, Inc. It is designed to be applied directly to the structural elements of a building — steel beams and columns, wood framing, concrete surfaces, drywall assemblies, FRP panels, foam insulation, and more than 40 additional substrate types.
F88 is classified as a passive fire protection system. Unlike active suppression systems such as sprinklers, halon systems, or fire suppression gases, passive fire protection requires no activation, no mechanical components, no water supply, and no electrical infrastructure to perform its function.
It is applied to a surface and it remains there — inert under normal conditions, reactive under fire conditions — providing a documented, certified layer of structural protection that is already in place before a fire event begins.
The mechanism that makes Firefree® F88 effective is intumescence — a controlled, heat-triggered chemical reaction that transforms the coating from a thin, paint-like layer into a dense, insulating char structure when exposed to elevated temperatures.
Under normal building conditions, a cured Firefree 88 application is a stable, low-profile coating layer on the surface of the treated structural element. It is non-reactive, non-toxic, and does not affect the load-bearing properties or surface characteristics of the substrate. The coating remains in this state indefinitely under normal temperature conditions, requiring no maintenance, no monitoring, and no mechanical intervention.
When ambient temperatures approach the threshold range — typically between 300°F and 400°F (149°C to 204°C) — the intumescent chemistry in the Firefree 88 formulation begins to activate. A blowing agent in the coating releases gas, initiating an expansion reaction. Simultaneously, a carbonific compound in the formulation begins to char. The coating begins to expand — in some configurations, expanding to 50 times or more of its original thickness.
As the expansion reaction completes, a rigid, multicellular char structure forms over the surface of the structural element. This char layer has extremely low thermal conductivity — it transmits heat at a fraction of the rate of the underlying structural material. The practical effect is that the temperature of the steel, wood, or concrete beneath the char layer rises significantly more slowly than it would if the surface were unprotected. For structural steel, which begins to lose load-bearing capacity rapidly above 1,000°F (538°C), the char layer created by Firefree 88 delays the point at which the steel reaches critical failure temperature. In ASTM E119 full-scale tested assemblies, properly specified F88 applications have demonstrated this delay to be up to 2 hours — providing the time margin that determines whether a structural fire event results in a survivable building or a total loss.
Stage 4 — Structural Integrity Window
The period between fire ignition and structural failure is the most operationally critical window in any fire event. It determines whether evacuation can be completed, whether suppression teams can respond effectively, and whether the structural shell of the building survives the event at all. Firefree® F88 extends this window — from as little as 15 to 30 minutes for unprotected steel under direct flame, to up to 2 hours for F88-protected assemblies tested to ASTM E119 standards.
Firefree® F88 does not extinguish fires. It does not detect fires. It does not replace sprinkler systems, fire suppression gases, or any other active fire suppression system. This distinction is fundamental to understanding how passive fire protection fits into a complete structural fire safety posture.
Passive fire protection is structural. It is applied to the building itself — not to a mechanical system that can fail. It requires nothing to activate. When a fire event reaches the structural members of a building, Firefree® F88 is already there, performing its function, regardless of the operational state of any active suppression system.
One of the defining characteristics of Firefree® F88 as a passive fire protection solution is its verified performance across an unusually broad range of substrate types. Most passive fire protection products are specified for a narrow range of materials — typically structural steel only. F88 has been independently tested and certified for application across more than 40 substrate types, making it one of the most versatile certified passive fire protection coatings available for commercial and industrial application.

The certifications associated with Firefree® F88 applications are not marketing designations. They are third-party tested, independently verified performance standards that carry direct weight with insurance carriers, building inspectors, OSHA investigators, and post-incident legal review.
ASTM E119 is the primary American standard for evaluating the fire resistance of building construction assemblies — walls, floors, beams, and columns. An ASTM E119 fire resistance rating is obtained through full-scale physical testing in an accredited laboratory furnace, where the assembly is subjected to a standardized fire exposure curve and evaluated for structural integrity, heat transmission, and flame passage over a defined time period. A Firefree 88 application that carries ASTM E119 tested documentation is not a theoretical performance claim. It is a laboratory-demonstrated result, conducted at full scale, by an accredited third-party testing facility. This distinction matters in insurance underwriting, post-incident investigation, and legal proceedings — where the difference between a tested, documented assembly and an untested claim can determine the outcome of a coverage dispute or litigation.
FM Approvals is one of the most recognized third-party certification organizations in commercial property insurance. FM 4470 covers roof assemblies and related components. FM 4975 covers wall and ceiling assemblies. FM Approval for a passive fire protection product signals to commercial property insurance carriers that the product has been evaluated, tested, and approved by an organization whose standards they recognize and trust. For facilities insured by FM Global or carriers that align with FM standards, F88 FM Approval documentation is a specific and recognized compliance credential.
ICC-ES issues evaluation reports for building products that demonstrate compliance with the International Building Code (IBC) and related model codes. An ICC-ES validated product has been reviewed by code officials and technical staff and found to comply with the code requirements applicable to its use. ICC-ES validation is specifically relevant for interactions with building departments, plan checkers, and code inspectors — particularly in jurisdictions that have adopted the IBC, which includes most of California and the majority of U.S. states.
International Accreditation Service (IAS) accreditation confirms that the laboratories conducting performance testing on Firefree 88 applications meet internationally recognized standards for laboratory quality management. IAS accreditation is a prerequisite for test results to be accepted by most regulatory bodies, insurance carriers, and code jurisdictions. It ensures that the performance data behind every F88 certification reflects testing conducted under controlled, verified, and reproducible laboratory conditions.
Firefree 88 is a water-based, low-VOC coating that qualifies for consideration in LEED v4 Indoor Environmental Quality credit categories for low-emitting materials. For project owners and developers pursuing LEED certification, F88 passive fire protection can contribute toward credit compliance without introducing VOC or off-gassing concerns that would compromise indoor air quality requirements.
