I was wondering if your product would work with our situation.
We have a metal roof (with blue skin on 12”plywood) then R42 closed foam spray foam insulation. We find it extremely loud when it rain! Ugh.
We hope to cover the ceiling with 6” pine Vjoint tongue and groove.
Would your product help reduce the noise significantly enough to justify the cost and time if installed under the pine T&G?
Also, would anything else need to be included for the installation?
