Prodex insulation for roof-over
Posted: Tue Mar 05, 2019 9:02 am
We're considering Prodex roll insulation (R-17) for a DIY metal roof-over on our peaked roof 14x48 singlewide. Anyone have experience with this material? Suggestions? Thanks, Rick
I am not sure how you would fasten it down. I would think you would need to go under the purlins to allow air flow under the steel. You will have condensation under the top layer of steel and you need to have air flow so it evaporates.
