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.

Highlights of The 2021 ICF Builder Awards

WHITEWATER CROSSING CHRISTIAN CHURCH
Fox Blocks provided a structural system that allowed the existing church to be expanded.

LAKESIDE RESIDENCE
Cost effective construction was possible because of the insulating qualities of the Fox Blocks system.
Is an ICF home quieter than a stick framed home?
Absolutely. The exterior walls are two layers of continuous insulation, the density of solid concrete and a layer of ½” gypsum board on the inside all contribute to superior sound suppression of STC 50 for the whole building envelope. Note: A wood frame system of equivalent STC rating would be 2 x 4 studs spaced 16˝ o/c, with 3½˝ absorptive material, 1 layer of 5 /8˝ Type X gypsum board on resilient channels spaced 16˝ o/c, and 2 layers of 5 /8˝ Type X gypsum board on the other side.
