Insulating Concrete Forms (ICF)

are hollow blocks or panels made of EPS (expanded polystyrene) plastic foam that construction crews stack into the shape of the exterior walls of a residential or commercial building. Workers then add reinforcing steel and fill the gap (typically 4” to 8”) between the two layers of polystyrene with concrete, which cures and hardens into a monolithic core. The polystyrene panel stays in place. This combination of concrete, steel and expanded polystyrene creates an incredibly strong and energy-efficient structure. ICF forms are a certified green material.


Depending on how costs are viewed, an ICF home may cost a little more or significantly less to build and operate.

Our prices are competitive with regular concrete block or frame construction. Florida Green Construction, Inc., as an experienced ICF contractor since 2007, strives hard to provide the  most superior product for your home.

ICF homeowners have peace of mind knowing they live in a hurricane, tornado and fire-resistant home plus they enjoy lower utility bills, better sound proofing, durability, substantial insurance savings and downsizing of heating and cooling equipment. Some have estimated that the monthly savings provide a real payback on the initial investment. And then you have the benefits of a stronger, quieter, more comfortable home.


As energy costs rise, you can bank on the fact that your lower heating and cooling costs will become an important resale feature. The Appraisal Journal conducted studies demonstrating the increasing value a home has by becoming more energy efficient. By including energy efficient upgrades, the home’s value can increase by approximately $20 for every $1 reduction in annual utility bills.

For example: the average monthly utility & insurance savings for an average size ICF home are approx. $250 per month, multiply that by $20 is $5,000.00 per month or $60,000 per year. This means the average ICF home appraised value will be approx. $60,000 more than a traditionally built home. This can help homebuyers to obtain more financing for the construction of the home and increase ICF home resale value.

Although the upfront cost of building with Insulated Concrete Forms may be more, the monthly savings will offset the increased monthly mortgage payment. For example, a $30,000 increase in the mortgage of a home adds approx. about $150.00 per month to the mortgage payment, but with ICF walls you will save about $250.00 per month so you still come out with roughly $100.00 in monthly savings!

In Conclusion:

The cost of ICF vs. traditional methods of construction is typically more for the actual construction, but the cost of ownership of an ICF home is significantly less than traditionally built home. In nearly every documented case of the expense of an ICF home, ROI - the return on investment for the extra construction cost is within five years, plus continued savings of thousands of dollars over the lifetime of the home.

only one house with ICF construction survived after hurricane Katrina

Our homes Built with ICF walls withstand hurricane & tornado winds up to 200 MPH. In the picture below, you can see a whole area that was swept away by a 20 ft. storm surge during Hurricane Katrina.

This ICF home withstood an F4 tornado which raked through Arkansas. Winds up to 200mph caused relatively minor damage to the ICF home, while all other homes in the path of the tornado were shattered beyond repair.

Fire devastated San Diego suburb

In this aerial photo of a firedevastated San Diego suburb, its easy to see the three houses on the street made with ICF walls. ICF homes have up to a 4-hour fire rating. The picture shows ICF homes that are still standing after a wildfire swept through the area.

This is how we can build a home for you.
