tab1234, Your pictures back up my question above. It's not about the windows as much as the siding. How is metal siding supposed to be installed to avoid this situation? Water can get under the siding (between siding and J channel) and trickle down inside the structure on a pole barn type build. It's not like the sheathed buildings with wrap, that can shed water down. Once it's on the inside of the metal, it is in the building. Or in your case, absorbed in the insulation.
Back to my question above, how do you seal metal siding around j channel windows on a pole barn?
If properly done as per the details attached, there are many ways to prevent what you question.
