Fox Blocks are a system of rigid insulation blocks made of EPS that are separated by plastic webbing. These blocks are insulated concrete forms, which means that during construction reinforced concrete is poured into the blocks to create a concrete wall (instead of a traditional wood plank or plywood frame). Once the concrete is poured, finishes (like drywall and siding) are attached to fastener strips embedded in the ICF walls. After ICF wall assembly, the ICF blocks fit together like Lego Bricks.
