Hi everyone – Looking for some clarification around how to best re-insulate a crawlspace that has falling fiberglass batts.
The crawlspace is under an enclosed 3 season porch (no heat or AC), the crawlspace has insulated steam pipe and h/c water pipes running through it. The vents were previously covered with plywood (but not air sealed). The house also had termites, so I need to be able to continue annual termite inspections.
Am I correct to use 6mil poly on the floor as a vapor barrier and rigid foam insulation on the walls, while leaving the rim joist uninsulated to allow for termite inspection? When coming up the wall, should the poly be attached over the rigid foam, or between the foundation/ exterior walls and the rigid foam?
Lastly, the exterior of the crawlspace appears to be stucco applied over some sort of chicken wire/board. Looking from inside the crawlspace, exterior wall has a footing and then the chicken wire/board is recessed about an inch – would I use the rigid foam on the footing and the wall, and tape the seam so it’s sealed?
