I am finishing off a room in our basement that had three uninsulated
concrete walls. I have already completed the stud walls insulated with
Kraft-faced glass-fiber insulation (facing to the inside).
My question concerns the wall between the room I am finishing and the
furnace room/workshop. The room I am finishing has a heating/cooling
vent at ceiling level (but there is no ceiling yet). The adjacent
furnace room/workshop has no vents, although uninsulated ducting runs
through it, so it gets a certain amount of heat simply by "leakage."
Should I insulate this wall? It has thin wood-grain paneling on both
sides, but has no insulation -- I took the paneling off one side and
looked. I plan to sheet-rock it.
If I do insulate it, which side should the facing be?
The insulation in that wall would be to keep the heat in the room I am
now finishing and stop it leaking into the furnace room. I don't think
the furnace room gets warm enough that it would help warm the adjacent
room -- but I cannot be sure of that.
Is there a problem using Kraft-faced insulation rather than unfaced?
Similarly for the wall between the family room and the unheated laundry
room. The latter has so much plumbing on the one exterior wall, and the
electric panel on the other, that it would be much easier to insulate
the wall between the two rooms than to insulate the laundry room.

I believe you might create a problem here depending how cold one side gets
compared to the warm room. You have a totally unheated laundry room? The
only heat it gets is from an adjoining room? I would venture to guess this
is where your water heater is also. Even if not, I think you would be
asking for trouble with freezing pipes maybe?
Kraft faced is a vapor barrier, you may create a moisture problem using it
on an interior wall. I've seen unfaced used as a noise reducer on interior
walls (don't know how much it helps, probably could Google and find out)
I would be concerned about freezing pipes depending on your location. Maybe
and maybe not, don't know extremes where you are. Sounds like a risky gamble
not heating a room with water pipes.
The water heater is next to the furnace. Is R-13 insulation between the
family room and the laundry going to cut down the heat flow to the point
where pipes will freeze? And there will still be heat flow through the
suspended ceiling in the family room and between the joists into the
laundry room, which has no ceiling. Also some heat from the kitchen above.
BTW, we're in W. Michigan, where it can get pretty cold in winter.

Sorry, I couldn't tell you if it will cut down the heat flow to the point of
pipes freezing. By you further explaining the design, it doesn't sound like
I was just in Michigan a couple months ago, in the Holland, Ludington, Honor
& Travis City areas. Absolutely beautiful beaches & country, guess that's
why we go back every year.
Michigan in the summer is not Michigan in the winter. The year I lived
there, all the Great Lakes froze over and the frost line went down over 4
feet. I lived east of Saginaw, the armpit of the Thumb.
