I have an attached garage I use as a workshop, and I'd like to insulate it since I plan on running water and sewer lines into the garage for a utility sink*. Right now, the garage is just studs and exterior wall. I don't plan on drywalling this garage. The ceiling is drywalled, since there is a bedroom above the garage.
I was thinking of just using fiberglass batt insulation. Would that be sufficient? If not, what is the best way to do this?
Edit: This house is located in Denver, CO. We get both warm summers and cold winters, but not a ton of humidity.
*Please note, I am going to have a shutoff valve and nipple drain on the line inside of the heated portion of the house. I don't plan on having this water line charged unless I need water in the shop.
