Just realized wool insulation fixed my van's damp wall issue

I used to think spray foam was the only way to insulate a van properly. It looked solid and sealed everything up tight. After a few months living in it, I woke up to wet walls and a musty smell every morning. A guy at a campsite told me to try wool insulation, so I pulled out some foam and put wool in one wall. The moisture problem went away almost instantly. Wool lets the van breathe, so no more condensation buildup. Putting it in was no big deal, just cut the batts to size and press them in. Now my van feels drier and stays at a nicer temperature all day long.

My friend in Alaska switched to wool after his foam insulation trapped moisture and caused rust. Wool doesn't just stop condensation, it actually pulls moisture away from the metal and releases it outside. This means the van's frame stays drier over time, which can prevent long-term damage like corrosion. I've been using wool in my van for two years now, and even in humid climates, the interior feels fresh. Plus, wool is naturally fire-resistant and handles temperature swings better than rigid foam.

Had the same thing happen in my shop van last year. Wool lets the walls breathe so the moisture just stops building up. Works way better than foam for metal bodies.
