I know there’s a lot of material to search on, but it will take me forever to find the answer to this question.
I know the value for loose fill but what R-value will cellulose packed to 3 or 3.5 lbs/cu.ft give me?
As usual, thanks for your help.

Your mileage may vary, but figure about 3.7 or so. An additional and often overlooked benefit of dense-packing is the air sealing.
*3.7 is generally accepted..which will give you R-13 for a 2x4 wall .... same as the nominal value for high density fiberglass with out teh edge leaks
*Thanks guys. I did do a search late last night using "mike smith" as key words because I know you often get into detail about energy walls. You're such a prolific poster it took me an hour to find the same figures. Thanks again. David
