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.
Yeah but how would you burn the building down sealing up around some pipes?

As I added in another comment, I'm a tenant.
