The Insulating Concrete Forms Wall Testing and Modeling report released by two Canadian groups, the B.C. Homeowner Protection Office and the B.C. Ready-Mixed Concrete Association, reveals that ICFs can be efficient walls, based on the results of a two-phased test. Twelve prototypes were tested, which "exhibited a very high resistance to both air and water infiltration," said Brian Hubbs, the senior building science specialist at RDH Building Engineering Ltd. Douglas Bennion, chairman of BCRMA's ICF Promotion Committee, said, "ICFs are best known in the construction industry in Canada as a foundation product, but they're more than that. They're concrete with brains, very energy-efficient and easy to install."
