Insulated Concrete Form (ICF) Walls
Insulated Concrete Form (ICF) construction results in structures able to withstand category 5 hurricanes. They utilize 3000 PSI concrete that cures over time to 4500 PSI. They incorporate rebar as structural reinforcement and achieve very low air filtration ratings for the life of the structure. Low air filtration combined with high mass result in R-50 insulation yeilds that dramatically reduces the resources required to heat and cool structures. Because the forms are left in place labor is reduced on removing forms, renting forms and installing insulation to the interior surface of the walls. Sandwiching the concrete and rebar reinforcement between interior and exterior sheets of polystyrene result in superior energy efficiency in any climate with minimal additional labor needed for creating surface attachments. ICF structures readily accept an unlimited selection of interior and exterior finishes. ICF structures are also mold resistant, allowing interior and exterior polystyrene insulation to dry out without trapping moisture when wet.
The ICF product category includes decking products for roofing and floors that withstand flood damage and roofs being ripped off by hurricane force winds. ICF construction also allows the ability to design structures that preserve the culture and historical architecture of the community while achieving unparalleled hurricane survivability and energy efficiency.
