Insulating with Foil-Faced Batts Behind Basement Tub
I am just trying to clarify on how to properly insulate behind a one piece fiberglass bathtub unit in a basement, that will be up against the outside basement wall. We are in zone 5 (Michigan). This is new construction. We have a poured wall in which we have 2″ of closed cell foam up against it and a framed wall in front of that. Now, we are getting ready to set in a bathtub against this wall. I am getting ready to install faced fiberglass in the framing but want to confirm if I should leave the facing on, or remove the facing. I’m a little unclear on if this would trap moisture or not.
I appreciate the help, and thank you in advance.
