Blown-in cellulose (settling)
I had 17″ of cellulose blown in between open-web floor trusses that supports a family room above an unheated garage. Recently I was installing a floor plug outlet in the family room floor and noticed that the cellulose depth was only 10-12″ deep max.
I contacted the installer, and to his credit he got back to me within a few days and is coming out to take a look.
My question is to what extent should cellulose settle, and how does one remedy this lack of insulation (also found a similar depth in another area while fishing for a buried wire).
