December 27 & 28, 2019–foam insulation panels and rim-joist insulation June 14, 2020 by Tim Swartz Northern Basements parked their foam insulation trailer in front of the old entrance, running a hose downstairs to insulate the rim-joist ends above the foundation. This is another critical step, which seals up air leaks as well as providing good R-value in this area above the foam panels The kitchen is protected with plastic, before the foam insulation is sprayed into the rim joists, above the suspended ceiling. We chose to not install foam panels on the kitchen wall, as we expect to eventually remove all the counters and appliances when we remodel the kitchen, but we wanted to seal up the joist ends along with all the other walls. At least 3″ of foam is sprayed into the rim-joist ends, and above the windows. You can see how the Northern Basement crew had to work around the heating ducts & the ceiling framing. Here’s the foam in the spaces above the foundation wall in the kitchen–in the foreground is the top of one of the fluorescent fixtures. Northern Basements crew boss Hunter is measuring for one of the last foam panels, in the stairwell. The white foam fills what would otherwise be empty space above the concrete basement wall. Northern Basements drilled through the siding into the rim joist spaces, in places where they were not accessible from inside. They did a very thorough job filling all the spaces!
