Despite how consistently and relentlessly the boys have dissed ICFs, this episode takes ICFs seriously and fairly (or as best as Jake, Steve, and Pete are capable of...).
Pete's Resource(s)
1. "Costs & Benefits of Insulating Concrete Forms for Residential Construction" (https://www.huduser.gov/publications/pdf/icfbenefit.pdf): A bit dated but still useful given that the PATH program (Partnership for Advancing Technology in Housing) is a decent backdrop for a fair analysis of this building technology.
2. "Air Leakage of Insulated Concrete Form Houses" (https://dspace.mit.edu/handle/1721.1/72627): Interesting that this energy modeling research reports less than significant air leakage advantage of ICFs compared to wood frame single-family houses.
