What if we told you one building block could be strong enough to withstand hurricanes, quiet enough to block noisy neighbors, AND help lower your energy bills?
These blocks are one of the construction industry’s best-kept secrets.
At first glance, they look like oversized LEGO® bricks, but these blocks are made from recycled Styrofoam, cement, water, and other carefully engineered materials.
Once stacked, they’re reinforced with steel and filled with concrete to create walls that create a strong structural grid.
Around 87% of each block is recycled EPS foam, and 100% of EPS in ICCF is recycled, giving old Styrofoam a new purpose. Instead of ending up in a landfill, it becomes part of a wall that can last for generations. They’re built to resist termites, moisture, earthquakes, and winds up to 250 mph. The walls are 700% stronger than wood or metal stud frame construction. That’s some serious peace of mind.
Benefits of ICCF Block:
- HEAT? HANDLED:
ICCF walls can achieve up to a 4-hour fire rating and won’t fuel a fire. It does not burn at an open flame of 4,000 degrees! - YOUR HOME’S COZY SWEATER:
Because the insulation stays on both sides of the concrete, the concrete core stays at a relatively stable temperature. That means the wall acts like a giant thermal battery, slowly absorbing and releasing heat throughout the day. With insulation values up to R-32, they help keep homes cooler in summer, warmer in winter, and more energy efficient all year long. - SILENCE IS GOLDEN:
The concrete core helps block outside noise, so your home stays calm, even when the world outside isn’t. ICCF walls don’t just reduce noise—they help block different sound frequencies thanks to the combination of foam, concrete, and air spaces. It’s like having built-in noise cancellation for your home. - THE BLOCKS AREN’T THE STRUCTURE…THE CONCRETE INSIDE THEM IS:
Think of ICCF blocks as permanent molds that never get removed. Once the concrete cures, the forms stay in place, providing continuous insulation for the life of the building. Traditional framing has wood or steel studs that allow heat to escape. But ICCF systems act as thermal bridges, reducing those weak spots where energy is typically lost. -
BIGGER BLOCKS, BIGGER IDEAS:
Many people assume the thick walls mean limited design options, but ICCF has been used for everything from modern minimalist homes to Mediterranean villas, schools, storm shelters, and even wine cellars, where stable temperatures are a huge advantage. -
THE BLOCK THAT DOES IT ALL:
ICCF blocks can create curves, custom shapes, and beautiful architectural details that prove strength and style can go hand in hand. We’re always excited by building systems that work smarter—not harder—and ICCF is a perfect example of sustainable design meeting high performance. Who knew recycled Styrofoam could become one of the toughest walls around? - WALLET-FRIENDLY:
Costs less than wood framing. The material be worked with standard carpenters’ tools. - BUG OFF BUGS:
The blocks themselves are termite and insect resistant because no wood is used. - SHAKE IT UP:
Capable of being approved for earthquake zones. - IMPROVED HEALTH: There is less dust and allergens associated with ICCF because it has an air filtration rate of less than 0.5 ACH (air changes per hour), far better than other traditionally-built buildings. The amount of air that leaks through structure envelope gaps is what consists of the ACH, so the lower the number is, the better the quality of the air.

“The sisters’ rooms are better insulated in the new building so not as many of us have gotten sick. The insulated walls keep us warm from the mountain air.”
