NE DesMoines,Ia | Thinking about building a new shop with steel lined walls and ceiling. Anyway different companys disagree on wall insulation .One i have been dealing with uses 6x6 post and 4" insulation . another one says i'm wasting $ using the 4"batt and they use 6"Batt therefor they don't have a dead air space next to the wall. Both use blown in the ceiling w/ R38 factor .What are your thoughts as i'm totally lost on this THANKS | |
