They make vent covers for crawl spaces but mine are an odd size. I need a recommendation for some sort of black, weatherproof plastic (or something) that can be cut to size and caulked into place to keep cold air and summer humidity out.
I’m not able to block from the inside so I’m trying to make this look as good as possible and cutting to size and tucking up against the metal vent will work best.
