Does the Fox Blocks contain recycled materials?
The plastic webs in Fox Blocks forms are 100% recycled postindustrial polypropylene. The EPS insulation is virgin material. Recycled content for an ICF block is measured by weight. The recycled content by weight of a standard 6″ Fox Blocks form — 48%.
Industry Standard ICF’s: Feedback from Contractors
January through April is when we plant our seeds for the year by displaying our product for the market in trade shows. I’ve participated in these trade shows for 17 years now in the ICF industry and it has always been the same old thing, but this year was notably different.

How ICF Reduces Production Time and Costs When Building a Movie Theater
ICF construction expedites the production of a movie theater and reduces labor costs over both wood-frame and CMU construction.
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.

Do I need an engineer to design and stamp Fox Blocks building plans?
Fox Blocks are listed in the building codes (IRC- Sections R404, R611 or NBCC Part 9) with specific applicability limits for residential construction. If the project meets the applicability limits within the building code, a Professional Engineer may not be required (dependent on local building department requirements). A building official has the right to request engineering and in some regions all projects require a professional’s stamp. For any projects that exceed the applicability limits, a Professional Engineer is required for the structural design. Check with your local building department.

A Better Approach to Fire Safety with Concrete Building Design
Non-combustible, insulated concrete form (ICF) construction is a better approach to fire safety over wood construction.
