Hi,
We are looking for some advice on insulating an existing metal roof on an existing barn. We need advice on how to mitigate any condensation concerns, noise concerns and whether rigid board insulation or spray foam insulation is most appropriate.
Many thanks,
Arron

Also, condensation is not a fun problem to have and also not a cheap problem to remedy. If you are going to be converting this into a home I would talk with a professional HVAC contractor and talk about a system to control the humidity in the structure as well.
