Dirt floor basement insulation. The sill plate is the first piece of framing lumber and it runs on top of the crawl space wall. Installing a vapor barrier over a dirt floor basement is an instant way to block moisture and insects from entering the basement space. Your best and first heat keeping are spent in insulating the attic and in sealing all the cracks that allow cold drafts into your house. Only seal and insulate your basement in combination with concreting the basement floor to seal out moisture that rises from the dirt.
Molly has given good advice. It has a solid block perimeter but has a dirt floor. What is the best way to insulate a basement and floor joists that are embedded into the concrete. The result of that is an unending source of humidity as moisture in the ground evaporates into the air and can condense on cold walls and joists where mold can establish itself.
A vapor barrier will help keep the levels of moisture down in the basement which can either compromise the home s foundation or increase the humidity level in the basement. In this video home renovation brothers dave and rich demonstrate how to insulate a crawl space. When you re using fiberglass batting insulation material run it about 6 inches or so onto the crawl space floor. All too often a crawlspace will have nothing but a dirt floor and probably some un insulated walls.
Cover the walls with insulation from the sill plate to the plastic covered dirt floor.
