Also question is, can insulation be installed backwards?
Some old insulation used to be entirely encapsulated, on ALL sides. I wonder if that’s what you’ve got. But if it’s fiberglass, with just one kraft facing on one side, then yes, it’s installed backwards.
Similarly, can I remove the facing from insulation? The batts may want to pull out as you remove the paper, so it might make sense to simply do it on the floor and reinstall backward so you have a cleaner face exposed to the room.
Thereof, does it matter which way insulation faces?
Regardless of whether fiberglass insulation is installed in a wall, attic, or crawlspace; the paper facing should always face toward the inside of the home. That’s because the paper contains a layer of asphalt adhesive which prevents water vapor from passing through it.
Which way do you face foil insulation?
Foil insulation underlayment is recommended under a metal roof, and in most cases, the shiny side should be facing up, but there’s a catch. Foil insulation is a radiant barrier, and it works by reflecting heat from the metal, but for it to do its job, there has to be a layer of air between the roofing and the foil.

Is internal wall insulation worth it?
Interior wall insulation can save on home utility costs, especially if the house has rooms that are not in use year-round. Three-season rooms, unused guest rooms or even storage rooms are expensive to heat and cool. Interior wall insulation will reduce heat transfer.
