Are there different types of Expanded Polystyrene (EPS)?
EPS is listed basically under four property classifications – Type I, II, III and IV. The characteristics are based on the density of the molded foam which defines the product type. Fox Blocks ICFs are manufactured as a Type II EPS with a density of approximately 1.5 pounds per cubic foot.
How does the ICF block get secured to the foundation?
The ICF blocks are held in place with either low expansion spray foam or a metal starter track. The bracing/alignment system, typically installed after the 4th course of block, also supports the ICFs in place. Once the concrete is in the wall there is no concern with the forms moving. The concrete is connected to the footing with reinforcing dowels.

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.
