I would like to blow cellulose into the wall cavities of my 1908 home. from what i can tell filling a 3.5 in. bay will get me to about R13. I want to get closer to R19. My framing is actual
2x4 which will get me a little more, but i fear very little.
does cellulose behave like fiberglass? if compacted does its R value decrease?
I imagine that this is an issue that folks that do blown in for a living encounter all the time and i wonder how its dealt with.
i'd love any input,
thanks
