ICF - The Next Generation Of Building.
Insulated Concrete Forms are precision-manufactured, double-insulated forms for reinforced concrete walls. Using Fox Blocks results in: a strong, high-performance wall assembly. The benefits just stack up.

Available in many shapes, sizes, and concrete core thicknesses. Our wall assembly works with all exterior-interior finishings you choose to use.
Create Any Design You Can Dream Up

ICF wall assembly meets and exceeds safety/resilience/durability requirements for Division 03 Concrete, Section 031119 ICF; Whole Building Design Guide (WBDG) Unified Facilities Criteria (UFC) & FEMA-ATFP Federal Military and DoD Standards FEMA-ATFP.
Strength Against the Elements

Our wall assembly provides indoor comfort and improves a building’s performance characteristics for the interior environment by eliminating moisture intrusion, managing the air flow and allowing for accurate climate control and minimizing sound mitigation.
Unparalleled Comfort and Quiet

The performance characteristics of our wall assembly can reduce a building’s heating and cooling cost dramatically (up to 50%) and puts Net Zero Energy goals within reach.
Lifetime of Savings
6 IN 1: The Elements That Make Our ICF Walls Superior

1. OUR CONCRETE FORM HAS REBAR SUPPORT
It’s one of the strongest wall assemblies available for below and above-grade walls, exceeding safety/resilience/durability requirements for FEMA-ATFP Federal Military Standards.
2. CONTINUOUS DOUBLE-LAYER INSULATION
Provides superior thermal comfort, energy savings, and sound mitigation. An R-value of 23.5+ plus whole-wall high performance enables Zero Energy Ready builds.
3. SOLID MONOLITHIC WALL AIR BARRIER
Exceeds the code minimum for airtightness. This natural continuous air barrier creates comfortable indoor environments with enhanced climate control.
4. A CONTINUOUS NATURAL VAPOR BARRIER
Create spaces with healthier air quality. Our wall assemblies have a PERM rating of <1.0, virtually eliminating moisture intrusion, mold and rot from your list of concerns.
5. FULL HEIGHT EMBEDDED FASTENING STRIPS
Gives you solid attachment for any exterior or interior finish, eliminating thermal bridging. They’re strong enough to work with everything from brick to siding.
6. REVERSIBLE INTERLOCK
Our block design saves construction time and reduces product waste, with a solid 2” parallel friction fit connection that’s easy, versatile and fast to assemble.
