What is ICF?

Insulated concrete form is a system of expanded polystyrene (EPS) rigid insulation blocks separated by plastic webbing. It is used as an integrated concrete form to pour a concrete wall instead of a traditional wood plank or plywood form. ICF blocks come in interlocking sections, so a wall system fits tightly together. Once the blocks are in place, concrete is poured, and finishes like drywall and siding are attached to fastener strips embedded in the insulation.

Insulated Concrete Forms are becoming a more common way to build homes. Historically most commonly used for foundation walls, many builders are now taking ICF further and using them for above-grade walls of 1, 2, and 3 story homes.

The concrete core enables ICF homes to withstand the most extreme weather conditions, including hurricanes, tornadoes, wildfires and earthquakes, to keep you and your family safe. The thermal mass and high R-value provides superior energy efficiency and lower utility costs over the lifespan of your home. Insulated concrete forms require less maintenance over time than wood, saving you the expense and effort of continuous upkeep.

Your dream home should be beautiful, safe and comfortable. With insulated concrete forms, or ICFs, your house can be all that plus environmentally friendly, energy-efficient and resistant to natural disasters. Building an ICF home, compared to wood-framing, offers increased durability, low maintenance and peace of mind that your house will last for generations.
