Basement Rim Joist Insulation in Canterbury, CT
Challenge
Leaky and poorly insulated Rim Joists can cause higher fuel and electric bills
The “rim joist” is the perimeter of the floor framing system along the exterior of the house. The joints and gaps between all the framing members allow for a lot of air leakage into the house. The rim joist is seldom insulated and never air sealed. Basement ceiling insulation, especially fiberglass batts, doesn't stop the flow of cold air into your home. A poorly insulated rim joist could make rooms more drafty, and uncomfortable, and create colder floors.
Solution
This was a problem for a homeowner in Canterbury, CT
Two-part expanding spray foam is installed on the rim joist and over the sill plate to insulate this important area of your home. Dr. Energy Saver’s spray foam has a high insulation value per inch of R7 because it expands, it seals all cracks and gaps and joints where air from the outside enters your home. This work results in warmer floors, less drafts, more comfortable rooms, your house is easier to heat and costs less to heat, and less summertime condensation on cold basement surfaces.
