After this homeowner of Freeport, NY had an evaluation of their home, it was observed that their rim joist was not properly insulated. This was causing cold floors, drafts and uncomfortable rooms in the basement/lower levels. The “rim joist” is the perimeter of the floor framing system along the exterior of the house. The joints and gaps between all the framings allow for a lot of air leakage. Triple H installed a two-part expanding spray foam on the rim joist and all over sill plate to seal all air leaks from the outside. Since this insulation expands, it seals all cracks and gaps and joints where air from the outside can get in. Resulting in warmer floors, less drafts, and more comfortable rooms.
