Case Study

Case study describing the incorporation of insulating concrete forms (ICFs) into new home design and construction.

Field Energy Performance of an Insulating Concrete Form (ICF) Wall

Reference

Research study evaluating the dynamic heat transmission characteristics through two identical Insulating Concrete Form (ICF) wall assemblies in Ottawa, Canada.

Construct exterior walls with insulated concrete forms (ICFs) that provide insulation without thermal bridging, as well as air sealing, a drainage plane, and high structural strength.

This community of production homes in central New York state was built with insulated concrete forms (ICFs), which provide a highly insulated, airtight structure that is fire-, pest-, wind-, and earthquake-resistant.

This 14-story multifamily building was constructed with insulated concrete forms (ICFs)

Concrete is being poured into the wall forms made by the rigid foam insulated concrete form blocks.

Image

ICFs provide continuous wall insulation from the roof to the footing with very little thermal bridging

Standard Specification for Flat Wall Insulating Concrete Form (ICF) Systems, ASTM E2634-18(2022)

Reference

A specification covering the application of Insulating Concrete Forms (ICFs) that act as permanent formwork for cast-in-place reinforced concrete beams & walls which was published in the year 2022 and is available for preview and purchase at the reference link.

Special molded corners provide continuous insulation layer at the corners to improve structural strength and minimize thermal bridging

Image

This multistory multifamily building was constructed of insulated concrete forms (ICFs); synthetic stucco can be applied directly over the ICF

Manatee County Habitat for Humanity trains its volunteers to construct homes made of construct insulated concrete forms (ICFs).

Image

In multistory insulating concrete form (ICF) buildings, the concrete floor slabs are integrated into the ICF exterior walls and structurally supported by the reinforced concrete wall cores

Image

Concrete is poured into the rigid foam shell of the insulated concrete form (ICF) walls; a plastic water barrier has already been installed to protect the below-grade wall surfaces.

Image

Wiring runs are covered with canned spray foam to maintain the continuous foam layer that covers the inside and outside of these ICF block walls.

ETW: Wall - ICF Wall Construction

A pumper is used to place the concrete into the foam form walls

ICF forms are filled with the use of a concrete pumper truck

The ICF consists of foam forms that are held in place with plastic or metal spacers and reinforced with metal rebar

Wiring runs are covered with canned spray foam to maintain the continuous foam layer that covers the inside and outside of these ICF block walls.

Seams in the ICF block are sealed so the EPS foam surface can serve as the drainage plane; no house wrap is needed.

Utilities are commonly recessed into cutouts in the foam after concrete has been poured

Thermal bridging is eliminated at the rim joist with the use of joist ledgers that are anchored in the wall
