In many homes, the rim joist is a significant source of heat loss and air infiltration. The area above the foundation can allow more air leakage than all the windows combined. Sealing the rim joist is a DIY project that can greatly improve a home's energy efficiency. It's also crucial to seal and insulate the top of the concrete wall where the sill plate sits. This is the simplest and most affordable basement area to insulate, providing the highest return on investment.
