Can condensation happen inside wood (without a surface)?
If a rafter has parts that get below dew point, and the rafter is encased in closed cell foam on both sides and above (foam board is on top of the deck on top of the rafter), condensation will happen whether or not there is a surface at / below dew point. Right?
(Theoretical question. I know there should be ventilation or adequate insulation, and I know foam sandwiches are not recommended. I don’t need practical answers to this question, thanks.)

Still couldn’t find an answer.
