Is ICF Sustainable In Extreme Weather?

Consider ICF, insulated concrete form, construction to provide a safe, durable, and comfortable home for your family or business.

ICF homes have survived hurricanes and tornadoes that flattened their conventionally framed neighbors, as seen here: http://www.theonestopbuildingshop.com/icf_survival_stories.html.

ICF buildings cost more initially, but quickly return the investment with savings on heating, cooling, and maintenance.

Ensure your builder, architect, or engineer is experienced with ICF construction and how local conditions affect the system.  Termite and carpenter ant resistant insulation should be used where these pests are problematic, water resistant insulation in floodplains, and thicker insulation might be desirable in cold northern climates.

The plan should include complete installation details.  There is too much variability between ICF systems to assume a component designer will anticipate every condition.

Ensure the builder doesn’t change ICF suppliers after the plan is completed.  Trusses, doors, and windows built to fit one system could require extensive repairs to match another.  Changing mid stream to save a few dollars on foam could cost a fortune in plywood for repairs.

The following links provide a wealth of information on ICF buildings, and sustainable energy and waste management products that go well with them.

  1. Real good advice. Also make sure to use an alinement system that can be adjusted as concrete is placed or the walls will not be in line. All good installers will use an alinement system and run a string on the out side of the wall. As the concrete is placed they literally tune up the wall by using the string to bring it perfectly in line. I hate to see ICF installs that have cut corners and ended up with non straight walls.
