lzerarc I know you are in the middle of an ICF build, what are your thoughts so far? I've looked at the green building site and I didn't find it that helpful--geared more toward professionals. I also saw some people reporting they had used Superior Walls and had leaks. Obviously that is a problem--a huge one. I also fear that if the crew changes the concrete by adding water, etc...during the pour you are going to run into major trouble and need to call in Mike Holmes a couple years down the road. Basically sound proofing, withstanding weather, fire and bugs are main reasons to use ICF? My understanding is a stick house can be insulated to the same level as an ICF home for cheaper? If ICF is fantastic why hasn't it caught on more? I'm interested in doing it but makes me nervous for possible problems.
