no. that is french for "too bad." you might remove some trees,
in keeping with our president's forest fire prevention program

i don't have any icf data. you might look it up somewhere, but use the real
vs bogus icf "effective r-value." premier's 8" sips have a real r32. an 8"
icf with a few inches of concrete inside would have less, weigh more, take
longer to build, and probably cost more.
