Insulation question - goaliedad - 05-29-2021 Getting ready to finish the main bathroom. The shower will be in a corner with one wall being exterior. 2 by 4 studs. I want to beef up the insulation on the outside wall. Options as I see them: Add to the studs and use 6 inch fiberglass Fill the 2x 4 wall with sheet styrofoam Leave the 3 1/2 inch fiberglass in place and put sheet foam over the studs, then drywall. 1 inch foil faced foam or 2 inch styrofoam? I really don't see an easy way to do the wall with spray foam. Your thoughts?

I'm not sure the 'benefit' will be worth the bother.

Foam board will be only marginally higher at 17.5. For greater insulation you would either need to go with spray foam or increase the stud depth. John RE: Insulation question - Tapper - 05-30-2021 I'm with John on this one as to your options; my choice would be the spray foam insulation (BTDT). More R value and air tight. However, in today's environment it may be difficult to get someone out to do a small job.
