Rim and Band Joist Treatment in North Potomac, MD

This homeowner in North Potomac asked us for help with advice on making their home more comfortable and advice on how to keep the home at a more stable temperature.  They were interested in having their attic and crawl space assessed.  Our energy auditor, Merv, visited the home and discussed solutions with these homeowners.  One of the recommendations was to air seal the rim and band joists in the basement area with 3" of closed cell spray foam insulation.  As you can see by the pictures, the rim and band joists were not air sealed prior to our work on the home.  We sealed and insulated the rim joists which are major sources of heat loss in the home.  This will make their home more energy efficient and comfortable and help keep the temperature in the house more even!
