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.

The two workers that performed this service were here for two consecutive days, and they were very courteous and friendly, and extremely competent and clean. They used drop cloths on the floors, covered clothing and other items in the walk in closet with plastic. When the job was completed, they hooked up the testing equipment once again, and reran the test to determine the reduction of cold air from the initial test. The numbers were very much an improvement, and we both notice that the entire house is now uniformly warm and, indeed, is somewhat quieter.
