Insulating interior basement walls


Hello,

First, I'd like to apologize for my lack of experience---I'll likely use some incorrect terms.

I just bought my first house and the basement has a partially-finished room that I would like to use for an office. It is wired, vented, and has drywall up with 2 walls being external and 2 being internal. Unfortunately, they failed to insulate the external walls before, so I know I need to do that. My home inspector suggested having loose insulation sprayed rather than taking down the walls.

My question is regarding the two interior walls. Do I need to insulate these from the rest of the unfinished basement? Eventually I would like to finish the entire basement, but it would likely be a year or two before that happens.

Thanks

Welcome to the forum!

Where are you located?

Is there poly sheeting plastic on the concrete?

Thanks for the reply. I am located in Utah and no, there is nothing covering the concrete walls and the ceiling has exposed batting in the non-finished areas.

You are in either Zone 5 or 6; http://publicecodes.citation.com/ico...001_par001.htm

I recommend using rigid foam board glued tight to the concrete wall with no vapor barrier: http://www.buildingscience.com/docum...ent-insulation

In the unfinished area, I would install a house wrap as an air barrier on the floor joists to prevent wind-washing of the fiberglass; The "biggest loser" in fiberglass insulation....

Foam board the rim joists after air sealing any/all wiring/plumbing holes to above; http://www.buildingscience.com/docum...m-at-rim-joist
