Insulating Concrete Forms (ICF)

Foam forms that are filled with reinforced concrete and reinforcement bar to create insulated structural walls.

Concrete forms have taken a new shape-and purpose. Insulating concrete forms (ICFs) are rigid plastic foam forms that hold concrete in place during curing and remain in place afterwards to serve as thermal insulation for concrete walls. The foam blocks, or planks are lightweight and result in energy-efficient, durable construction.

Insulation values of ICF walls vary depending on the material and its thickness. Typical insulation values range from R-17 to R-26, compared to between R-13 and R-19 for most wood-framed walls. Additionally, ICFs are more resistant to moisture, termites and other pests, and can dramatically increase the strength of the home while reducing noise from the outside.
