Foam Board for Ceiling Advice
Hi everyone. So I know there's much debate with insulation and usually the best bet is spray foam. We've opted for foam board insulation, as it's much more cost effective for us. It seems to be doing well for the side panels.
My biggest concern is that I've read about issues with condensation when using the boards. I've also read and seen people use it just fine.
So my questions are, what makes it work? Is there a good technique? Is there something that helps prevent the issue?
We plan to use a vapor barrier, but I just want to make sure I go in with the best knowledge I can because stuffs not cheap and I want to prevent moisture and future mold/rust issues as much as I can.
I appreciate any feedback!
