How to Build a 4-Hour Fire Wall: Thickness, Materials, and Assembly
4 Reasons to Rebuild with ICF Walls After Wildfire Devastation
Rebuilding after a wildfire with Fox Blocks insulated concrete form (ICF) construction can protect a new structure and its occupants from future wildfires.
Does expanded polystyrene (EPS) present a serious fire hazard?
The EPS in an Fox Blocks has a flame retardant that allows the forms to be flame resistant. The EPS will melt when exposed to sustained temperatures over 300°F (149°C). The ignition point of the melted styrene is 600°F (315°C) (wood is approximately 500°F (260°C). Fox Blocks have been tested to meet the building code requirements for flame spread and smoke development, plus Fox Blocks may be used as fire resistant rated wall assemblies in schools and hospitals.
