Help with insulating ol’ bunglalow
My own house is a 30’s West Coast bungalow with plaster walls, lap siding and empty stud bays.
I’ve thought to blow in insulation, but I’d like to ask this of the experts first:
The lower half of this 1 1/2 story house has no sheathing and no building paper of any sort. The siding, 1×8 Dfir cut in a double V with a rabbet, is nailed directly to the studs. The upper half has cedar sidewall shingles over 1x boards but still no tarpaper.
I am concerned that if I blow in insulation, the things won’t breathe, moisture could become trapped in the walls and I’d get mold/rot issues. This is rainy Oregon–it’s hosin’ out there right now!
In this particular room, I’m going to pull down all the plaster anyway, so I thought I could use the fiberglass batts that are cased in film to prent any water that makes it into the walls from wetting the insulation.
Any other thoughts?
Thank you,
Pat

Since your going to open the walls anyway, you might want to consider foam.
There have been several discussions here recently on the advantages; just scan back over the last 100 or so posts in this section.
Good Luck
