In this photo you can see a finished Dr. Energy Saver Rim Joist Spray Foam Insulation treatment. We realized that like most other homes, this basement did not have and air sealing on their rim joist. This allows air from outdoor hostile environments to leak into their basement and then up into their home. We sprayed our two part spray foam on the rim joist and over the top plates to seal all air leaks from the exterior of the home. This sealed up all of the cracks and gaps that were previously allowing air from hostile outdoor environments to enter the home.
