Endless design configurations – Fox Blocks are available in a wide range of shapes, sizes, and concrete core thicknesses. They work with just about any exterior or interior finish, including EIFS, traditional stucco, brick, stone, fiber cement siding, or drywall.   


Fox Blocks Series configurations: 


The Fox Block “Straight Block” typically makes up between 80%-85% of the ICF wall assembly on most residential and commercial jobs, while the 90-degree “Corner Block” typically makes up 15%-20%.  


Below are all the form configurations, engineered to work together as a complete building system.   

Fox Block ICF features: 


Fox Blocks offer significant advantages, making them one of the highest performing and most requested ICF offerings on the market. 


Reversible design – Universal forms with no top or bottom, no right or wrong side, and no left or right corner mean easy stacking. 


Engineered ties – Fox Block ties have stout strength and an open truss design that allows for proper concrete consolidation. 


Top-stacking ties – Eliminates the settling of forms during concrete placement and creates a continuous vertical fastening strip with no gaps.  


True 1.5 density EPS foam – The foam always feels solid, and you’ll experience less damage to forms during handling.  


Right-sized furring strip – At 1-1/2" wide and 16" tall, the strips easily attach to drywall and exterior finishes. The tested fastener pull-out strength is equal to or greater than wood.
