Any idea what these vents are for?
Any idea what these vents are for?
(OP)
I'm connected with a commercial home inspection group and we're trying to figure out what these vents were for. They were outside a 4500 sq. ft. facility with nothing inside that might have given a clue. Nothing unusual. I believe the place was empty at the time of the inspection (not mine).
