Crawlspace insulation advice
Hi – Let me describe our crawl. It is about 3 to 4 feet tall and about 20×20 feet. We have a vapor barrier, sump, and dehumidier. The space is dry because of the dehumidifier. The ceiling and walls are both insulated. We’ve always just had a crawlspace smell in the area above the crawl and can’t seem to get rid of it. I’ve tried blocking vebts and opening them but I can’t get rid of that slight smell.
One thing I haven’t tried was removing the crawl wall insulation and just leaving the ceiling. Would that allow more air movement in and out through the cement wall? Are their reasons you shouldn’t insulated both ways? Any advice will be appreciated.
