Delamination around fridge vents

I have noticed a few mentions of outside wall delamination around the two big fridge vents. I may have found the reason. I took my vents off, and the exposed styrofoam in the wall cuts was not sealed with anything.

The bottom of the lower vent hole was siliconed, as I imagine FR expects some moisture issues there, and one side was done. but that was it. The other side and top of the hole were unsealed, as was the entire upper vent hole. The styrofoam core of the wall was exposed on all sides.

I can easily imagine that, over time, the styrofoam would absorb humidity, or maybe even water when flying down the road in a rainstorm. Moisture in wall = delamination.

So I got out my caulking gun and rubber gloves, and glopped on a pile of silicone, rubbing it into the styrofoam for a good seal, and making sure there were no gaps in my sealing job.

I also noticed a few pinholes in the caulking around various external fixtures, and will be re-caulking them once I get the right stuff for the job.

This may be a good time to check and see if you are going to have an issue around some of these areas, where there may be an indicator of cracked caulk or a gap and cover them up until Spring if the weather where you live keeps you from making repairs now. If you wait til spring it may be too late!

Went and had a quick look and mine is only caulked on the bottom. You can see where the wood is actually starting to stain from the dampness. So I have the cover in the house to figure out a way to seal it up abit. Too cold to do anything outside and I have to wait for the cover to warm up to try and seal it at all. Actually used a piece of heavy vapor barrier and put it behind the panel to keep anything out till spring when it can be sealed.
