Every ICF manufacturer says their ICF Block is the Best, interesting then that Stronghold was born from many years of frustrating ICF construction experience on job-sites, trying to make other ICF brands work how they should. The Stronghold ICF block was specifically designed to benefit from this knowledge & put it to good use, a philosophy embraced by some of the highest quality ICF molders in North America. Knowing the quality of ICF block required to build straight concrete walls without gaps, bulges, blowouts, or the huge amount of time & extra money typically spent on wood strapping & screws is what makes Stronghold ICF confidently different.
Stronghold ICF was designed & developed to build Straight, Trouble-free walls - Helping Contractors to have the confidence to Build their Business with ICF.

Key Benefits
Highly Energy Efficient
The foam in Stronghold walls insulation performs like a R-24. This exceptionally high R-value, along with high thermal mass and reduced air infiltration, allow Stonghold walls to deliver significantly higher performance levels.
Strength and Safety
Stronghold buildings are up to 8.5 times stronger than conventionally framed buildings. As a result, St walls are much better able to withstand severe weather such as hurricanes and tornados.
Superior Sound Insulation
Stronghold walls offer you a quieter, more tranquil interior environment. Loud noises outside a Stronghold building will be reduced to a whisper inside the building.
Highly Moisture Resistant
ICF walls don't need an extra vapor barrier. For below-grade applications, Stronghold provides a waterproofing system that ensures a comfortably dry basement. Improved air quality is another benefit as Stronghold eliminates the studs and cavities that can hold moisture and foster mold and mildew growth.
Environmentally Friendly
Buildings constructed with Stronghold are designed to last for centuries, not decades. Stronghold ICF walls conserve precious natural forest resources and their energy efficiency reduces fuel consumption. The use of Stronghold promotes sustainable, green building practices, and is an investment in the future.
