Leaky rim joists and un-insulated foundation walls in crawlspaces are often the major infiltration point for outside air. During the cold winters in the Twin Cities Metro area, these areas leak out hot air, cooling the basement and taxing heating equipment, especially when ductwork and plumbing runs through the space. Cool, air-conditioned air leaks out during the summer, slowly turning your cool home into a lukewarm, uncomfortable space.
Making sure these areas are properly insulated and sealed is key to maintaining comfort in the home and keeping your utility bills down.
“Conditioning” Your Crawlspace
Properly insulating a crawlspace usually means bringing it into the “conditioned space” of the home, so the environment in the crawlspace matches the environment in, say, the bedroom. Rather than isolating the room above from the crawlspace, the space is sealed and insulated against the outdoor (“ambient”) air.
Controlling Outdoor Moisture
Unfinished crawlspace floors should have a vapor barrier in place. The walls and rims should also be insulated with closed cell polyurethane foam. These measures ensure that only minimal amounts of heat are lost to the outside, and that no moisture migrates in from the surrounding soil.
In some taller crawlspaces, foam board may be applied to exterior walls as well. Moisture wicking insulation materials (like fiberglass) should not be used in these spaces. If SCES is doing a renovation, we’ll often discard any leftover fiberglass insulation, since it retains moisture and odors.

We used St. Croix Energy Solutions to insulate our rim joists and basement walls. They used foam on the rim joists and insulated two basement walls. They were on time and were very professional. They put up plastic around where they were working as to not contaminate the surroundings. They were very efficient and cleaned up when done. I would recommend them to do any insulation needs you may have.
