Insulated Concrete Forms (ICFs) are a type of construction technology that involves stacking foam blocks, pouring concrete into the gaps, and using reinforcing steel to create a strong, energy-efficient, and durable structure.

Resembling a large Lego block, ICFs are lightweight foam blocks made from hypoallergenic EPS hard foam (expanded polystyrene) that are stacked together to make up the foundation and walls. Once assembled into the desired shape, they are filled with concrete making the building incredibly strong and energy efficient.

Did you know? A study by the Portland Cement Association shows that over the lifespan of a house, ICF has a reduced CO2 burden vs. wood-frame construction by 220,460 lbs.

The Problem

Air Leaks in Traditional Homes

Traditional wood-frame homes have dozens of air leak points. Hot air escapes in winter, and cool air escapes in summer—forcing your HVAC to work overtime.

Common leak points include: attic hatches, recessed lights, duct registers, plumbing vents, sill plates, and more. These leaks account for 20-30% of your energy costs.

Thermal mass effect on internal temperature

The Solution

Thermal Mass: Your 24/7 Climate Buffer

ICF's concrete core acts as a thermal battery. It absorbs heat during the day and releases it at night—naturally stabilizing indoor temperatures without your HVAC running constantly.

This "thermal flywheel" effect delays peak temperatures by up to 6 hours and reduces temperature swings by up to 14°F compared to wood frame construction.

Hours to reach thermal equilibrium - ICF vs Wood Frame

ICF takes 144 hours to reach equilibrium vs just 4.8 hours for standard wood frame

Verified Performance

Blower Door Tested Air Tightness

Every ICF home can be verified with a blower door test—a diagnostic tool that measures exactly how airtight your building envelope is.

ICF homes routinely test at less than 1 air change per hour at 50 pascals (ACH50), compared to 5-10+ ACH50 for typical wood frame construction. This means:

Dramatically reduced energy bills
No drafts or cold spots
Better humidity control
Improved indoor air quality

Benefits of ICF Construction

⚡

Energy Savings

R-24 insulation with virtually zero air infiltration. Save up to 50% on heating and cooling.

💪

Superior Strength

10x stronger than lumber-framed homes. Survives hurricanes, tornadoes, earthquakes.

🔥

Fire Resistant

Up to 4-hour fire rating. ICF foam self-extinguishes and will not burn.

🔇

Whisper Quiet

STC ratings of 50-55 mean only 1/8 as much sound penetrates vs wood frame.

🌿

Healthy Living

No formaldehyde, asbestos, or VOCs. Prevents mold and radon infiltration.

🐜

Pest Proof

Concrete and foam are unappealing to termites, carpenter ants, and rodents.

🌍

Environmental

Reduces CO2 burden by 220,460 lbs vs wood-frame. Made from recycled materials.

🏛️

Longevity

Concrete requires little maintenance and stands up to nature. Built to last.
