The 2021 International Residential Code has several provisions aimed at curbing energy consumption in homes. It’s imperative to educate those in the field on both the code and industry best practices, using the right products in the right way to achieve a project’s performance goals.

The requirements there address insulating rim joists so that insulation is in permanent contact with the exterior rim board, that shaft and penetrations to the exterior are air-sealed and insulated, and that narrow cavities be filled with insulation—among other important details. In addition to the code itself, we’ve included articles that demonstrate and explain how to accomplish these commonly required air-sealing and insulation details.
