These homeowners wanted their home to be more comfortable. The rim joist is the perimeter of the floor framing system along the esterior of the house. The joints and gaps between all the framing members allow for a lot of air leage into the house. The rim joist is seldom insulated and never air sealed. Our Team used our two part expanding spray foam to seal all air leaks. Our spray foam has a high insualtion value per inch and because it expands, it seals all cracks and gaps preventing air from leaking into the home. This home will be more comfortable as well as easier to heat and cool.
