Rim Joists
Many building components come together at the rim joist such as the foundation wall, the sill plate, and the subfloor. It's important to seal all cracks against air leakage. We use an expanding polyurethane foam that is sprayed in strokes
Air Leaking
The air can't leak in anymore!
Hot in the Summer and Cold in the Winter
Sealing your rim joists will save you money in the long run. Uninsulated rim joists make homes harder to heat in the winter and harder to cool in the summer
Pipe Penetration
Anywhere the pipe is penetrating an exterior foundation wall, spray foam should be applied. It's all about sealing from the outside air!
