Build stronger, more energy-efficient walls with Stronghold Insulated Concrete Forms (ICF), a contractor-focused wall system designed to help create straight, durable concrete walls with fewer jobsite headaches. Stronghold combines EPS foam insulation with reinforced concrete construction for residential, commercial, foundation, safe-room, and other high-performance building applications.
Stronghold ICF blocks are engineered with features aimed at improving installation and wall stability, including thicker foam panels, continuous interlocking webs, reinforced corner designs, built-in rebar supports, and heavy-duty fastening flanges. These details help reduce movement, bulging, and the risk of blowouts while giving contractors secure attachment points for exterior and interior finishes.
Available in FX-Series fixed-web blocks and FD-Series folding blocks, Stronghold offers multiple core sizes and configurations to fit a wide range of projects. With high-performance EPS insulation, reliable stacking, and jobsite-friendly features built directly into the system, Stronghold ICF provides an efficient solution for contractors looking to build durable, comfortable, and energy-efficient structures.
