crawl space vapor barrier 3

When you're down in the crawl space, that vapor barrier is doing a lot more than just lying there—it's stopping ground moisture from seeping up into the insulation and framing, which can lead to rot and mold. I always make sure the seams are overlapped and sealed tight, because even a small tear can let damp air through and undermine all that hard work.
