Air Seal and Insulate a Rim Joist in Windsor, CT

This homeowner in Windsor, CT wanted to reduce drafts and humidity in the basement.  Rim joists are often uninsulated which allows cold dry air to enter the home in the winter and warm humid air to enter in the summer.  Our team used our closed-cell polyurethane spray foam insulation to air seal and insulate the rim joist.  Our spray foam has an insulation value of R7 per inch.  The foam expands ensuring all cracks and gaps are sealed to prevent outside air from entering.  The homeowner will have warmer floors, their home will be more comfortable and easier to heat and cool.
