This is for a rental unit, so I’m trying to keep the cost low, while also sealing it away from silverfish. I have very fine steel wool on hand as well as a tube of DAP ultra clear flexible all purpose sealant.

      Wrong foam insulation resulting in overheating or toxic/ flammable off-gassing, wrong amount of foam, attaching something conductive to the copper pipes, accidentally nicking a wire in the wall, I don’t know about a billion things could go wrong, and you don’t want it to be your fault if it does.
