What is ICF?
Insulated Concrete Forms (ICFs) are forms for cast-in-place, reinforced concrete walls. The forms are left in place permanently to serve as thermal and acoustic insulation, allow space to run electrical wiring and plumbing, and as backing for gypsum boards on the inside and stucco, brick, or other siding on the outside.
The forms are usually made of foam insulation and are either
separate panels that are connected with plastic ties or
pre-formed interlocking blocks
Different ICF systems also vary in the shape of the resulting concrete within the wall:
"Flat" systems form even thickness concrete throughout the walls, like a conventionally poured wall.
"Grid" systems create a waffle pattern where the concrete is thicker at some points than others.
"Post-and-Beam" (or "Screen Grid") systems form discrete horizontal and vertical columns of concrete (no fire resistance).
We build using a flat system due to its versatility, low waste, and compact storage/shipping.
Benefits
Ideal for building in areas with a high incidence of natural disasters like earthquakes, hurricanes, tornadoes, floods, and wildfires due to to its structural integrity and endurance.
Energy-efficient with lower heating and cooling costs due to its high R-value, high thermal mass, and air-tight construction.
Resists deterioration from environmental elements like humidity and termites.
Ideal for building in areas close to freeways/expressways, railroads, and airports due to its ability to diminish outside sounds and provide quieter interiors.
