Four Hour Fire

When it comes to protecting your property—and the people inside—fire resistance matters. That’s why at Integrity, we build with Insulated Concrete Forms (ICFs), which offer fire ratings of up to 4 hours.

Fire Resistance You Can Count On

 

What Does a 4-Hour Fire Rating Mean?

A 4-hour fire rating indicates that an ICF wall can resist the passage of fire, smoke, and heat for up to four hours under standardized testing conditions. In real-world terms, it means:

  • Greater safety for occupants in the event of a fire

  • More time to evacuate and respond

  • Less structural damage, thanks to the non-combustible concrete core

  • Lower insurance costs for some residential and commercial buildings

Why ICF Is More Fire-Resistant:

  • Non-combustible concrete core: Won’t burn or contribute to fire spread

  • Fire-resistant foam insulation: Specially manufactured to meet or exceed fire safety codes

  • No cavities or gaps: Slows down flame movement compared to wood-framed walls

Build Safer with ICF

Whether you're building a home, school, medical facility, or commercial space, fire resistance is a critical feature—and ICF delivers. With up to 4 hours of fire protection built into every wall, you’re investing in long-term safety, resilience, and code compliance.
