Hey everyone! I'm looking to temporarily block my crawlspace vents and need some advice. I want to use foam that I can easily shape to ensure a snug fit, and it should be able to withstand outside weather (we get some rain but no snow). I've found three options at Home Depot: 1) Owens Corning FOAMULAR NGX, 2) R-Tech, and 3) RMAX Pro Select. Can anyone suggest which of these would work best for my purpose? Thanks a lot!

I've seen some folks use simple plastic vent covers that you can fold up, which might be a good option. You don't really need foam insulation unless you've already insulated your crawl space walls. If you have some larger styrofoam blocks lying around from packaging, they can work well too! Just a heads-up, it can get messy to cut, so do it outside. At the store, definitely check how easy the foam board is to cut; I noticed some types are really rigid but the pink board is softer. It's worth comparing to see what fits best for your needs!
Would the pink foam board perform just as well exposed to the outside?
