Rim Joist Insulation
If the basement rim joist is not accessible, drywall would need to be removed to properly insulate it and the foam may need to be injected into the cavity instead of spraying it.
Basement Wall Insulation
Studded walls of an unfinished basement can be sprayed with foam, while walls with drywall would need to have holes drilled between the stud cavities to inject foam in them.
Basement Ceiling Insulation
If there is a drop ceiling, the tiles will be removed and the space will be sprayed with foam insulation. If there is drywall, then holes will be drilled into the ceiling and injection foam will be used.
