RDH Building Engineering Limited is running extensive tests on the viability of using insulated concrete forms (ICF) as walls in building structures. While ICF has traditionally been used below grade, it is becoming possible to also use forms for above-grade work.

RDH Building Engineering Limited is running extensive tests on the viability of using insulating concrete forms (ICF) as walls in building structures. While ICF has traditionally been used below grade, it is becoming possible to also use forms for above-grade work.

Brian Hubbs, a principal with RDH, spoke to the Journal of Commerce about the testing process with ICFs, including showering the material with the equivalent of an intense Vancouver rainstorm to test seals between structures like walls and windows.

Hubbs said tests indicated several commonly used installation methods had less than ideal performance levels, while ICF cores showed high resistance to both air and water infiltration.

Hubbs also cautioned that once one goes above grade, it becomes important to concentrate on “interface details” like fireplaces, windows and doors, features that are almost never a concern below grade.
