Air Sealing Before & After Photos

While working on this attic in Binghamton, NY; our crew here at Foam It Insulation takes great care to seal many of the place air escapes into that many others don't think of sealing, such as can and recessed lighting fixtures, as well as top plates in the ceiling. Before insulating the attic with our TruSoft blown cellulose insulation, we ensured the attic was tightly sealed by sealing the rim joists as well as top plates.

This very leaky attic was costing the homeowner a lot of money when it comes to the energy bills. It's surprising to learn can lights are a top problem in uneven temperatures in most homes. The best way that we could help them out was to air seal and insulate their attic using spray foam insulation and SilverGlo.

The rim joist is the perimeter of the floor framing system along the exterior of the house. The joints and gaps between all the framing members allow for a lot of air leakage into the house. The rim joist is seldom insulated and never air sealed. Basement ceiling insulation, especially fiberglass batts, don't stop the flow of air, cold in the winter and hot in the summer, into your home. We suggest that two part expanding spray foam (also known as closed cell spray foam) be installed on the rim joist and over the sill plate to seal all air leaks from the outside and insulate this important area of your home. Foam It Insulation's spray foam has a high insulation value per inch of R7, and because it expands, it seals all cracks and gaps and joints where air from the outside enters your home. 

The perimeter of the floor framing system along the exterior of the house is called the Rim Joist. Air leakage comes from the joints and gaps between all the framing members. Air Sealing and Insulating the rim joist is something that contractors hardly ever do. Basement ceiling insulation, especially fiberglass batts, doesn't stop the flow of air, cold in the winter and hot in the summer, into your home. We suggest that two part expanding spray foam be installed on the rim joist and over the sill plate to seal all air leaks from the outside and insulate this important area of your home.

In addition to doing the crawlspace encapsulation in this home, we also spray foamed the rim joist in the part of the home that had a basement area. This will also make the upstairs more insulated and make the overall home more comfortable.
