Does the EPS provide support for a wood sill plate?
No, the EPS has no structural capacity to support any loads. Wood sill plates must achieve the required bearing from the concrete within the ICF. A wood plate that cantilevers 1⁄3 over the EPS and bears 2⁄3 on the concrete is allowable. This can be done with a minimum 2 x 6 plate. If a 2 x 4 plate is required, a taper top form should be used to extend the concrete under the plate.

What is the Concrete Temperature Limit?
Concrete is a versatile and durable construction material that is predominantly used in both commercial and residential structures. It’s essential to understand concrete’s thermal properties, specifically its temperature limits, to optimize its strength and durability.

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.

Effective Strategies to Insulate Block Walls
Improving the insulation of block walls significantly enhances energy efficiency, comfort, and durability in both residential and commercial spaces. Block walls, often made of concrete masonry units (CMUs), are sturdy but notoriously poor at retaining heat without proper insulation.
