Roxul comfort board in basement?
I spoke to someone at the Roxul company the other day who recommended the following basement insulation. First, tyvek or similar against the concrete basement wall, then 1 1/4 " roxul comfort board for a thermal break, then a stud wall filled with roxul batts--- sheetrock. Do you see a real problem with water condensing on the concrete with the comfort board and tyvek there? Still seems like too much work but I am curious performance wise.
I read the article about roxul board as a foam alternative under siding. It seems like such a solid long term product compared to foam.
Hopeful for cost effective foam alternatives for basement--- no luck yet.
