What Fox Blocks does
Fox Blocks is a US-based manufacturer of Insulated Concrete Forms (ICFs) and a division of Airlite Plastics Company, headquartered in Omaha, Nebraska. The company produces precision-manufactured, double-insulated wall systems consisting of expanded polystyrene (EPS) foam panels joined by injection-molded polypropylene plastic ties, which serve as permanent formwork for steel-reinforced concrete walls in residential and commercial construction. Its product portfolio spans the Fox Blocks Series (straight, corner, T-block, radius, taper-top, brick-ledge, and specialty configurations), the Fox Blocks Compact panelized system shipped flat for freight efficiency, and a proprietary accessories franchise including the patented tieKey masonry anchor (US 8,347,581), the patented xLerator ledge reinforcement (US 7,437,858), the Fox Buck continuous-insulation opening system, the Energy Stick R-value booster, the HV Clip, and the 2025-launched Fox Foam spray foam.
The company sells primarily through a North American dealer network (US and Canada) supplemented by direct factory engagement on large commercial and institutional projects such as the $43 million Discovery Elementary School. Specification-stage engagement is driven by BIM/Revit content distributed via BIMsmith Market and a free Revit Family Configurator on BIMsmith Forge, AIA-accredited continuing education courses through AEC Daily, an Integrated Learning Center (ILC) for installer training and certification, and multilingual (English, Spanish, French) technical resources. Fox Blocks holds a broad stack of building-code certifications (CCRR-1010, Florida FL7497-R6 HVHZ/Miami-Dade, NYC MEA, LA LABC, ICC 500, LEED NCv4, ASTM E119 fire ratings, FEMA-ATFP/DOD) and operates partnerships with ICFMA, NRMCA's Build with Strength coalition, Habitat for Humanity International, ACPA, and Swatchbox. Revenue is generated almost entirely through one-time product sales rather than subscriptions or recurring contracts; pricing is quote-based and varies by project scope.
