Bare walls and fiberglass insulation

People frequently ask about the insulation in the crawl space at home shows and events. They ask if it needs to be taken out. We always recommend the best option available. In this case, the existing insulation wasn't too bad so it was left in place. The bare concrete walls let a lot of water vapor into the crawlspace since the dirt outside the perimeter of the structure is usually very moist. The CleanSpace vapor barrier seals all that moisture out and makes for a usable space!
