Insulated Concrete Forms

Yesterday in the Greensburg update ICFs (Insulated Concrete Forms), were talked about
as being the green building material of choice on at least a couple of projects. This
stuff caught my interest so I delved into it a little. Here’s what I found.

ICF is a block form that has 3 inches of styrofoam on two sides with a 6 inch plastic
spacer in the middle with slots to pop rebar into. They stack together to form walls
and buildings and concrete is poured into the middle of the forms.

Buildings made from ICFs are energy efficient, enviromentally friendly, solid, built
to last, quiet and comfortable. They lower the potential for mold and allergens by
keeping out the air and moisture. Cooling and heating cost are reduced because the
interior temperatures in ICF buildings remain steady throughout the seasons. They
resist the ravages of time, fire (up to 4 hours), and wind (up to 200 mph).

Most are produced from recycled materials and even the unused portions can be recycled
to make the least possible impact on the enviroment.

I like it!!!

    This seems to be the ideal way to go. I do however see a possible problem with something like this. I live in South Africa, here we have a desperate shortage of housing. Something like this could push up the price of construction and thereby make the housing shortage problem worse. Money seems to creep into everything doesn’t it?

    I see you point but in this case it is cheaper! You need no wood, no insulation, just concrete. Those forms stay in place…. construction labor can be reduced by doing it yourself!

    Hi Linda,

    I’ve seen these being used and they’re awesome. Whoever came up with this idea was a genius.

    Sounds ideal. Any idea of the costs associated with using this as your main building material?

  5. Linda Says:

    hi Barbara … yes! it is a very good product and there are many varieties. So buyer must research what is best for them.

    Hi Michellew … From what I can tell, most of the icfs run between $3 to $5 per square foot. Again, depends on which icf product you choose.

    Sounds like they’d make quite the fortress.

    I love ICF. It’s a great option for a green home. One builder told me that the home he built (nearly 3000 s/f ICF) would average electric bills of $25/month because of the enormous energy efficiency of the walls!
    More about ICF on the following page:

    I’d love to see it become more and more popular – we’d sure save boatloads of electricity and cash over the long haul if we use it.
