I really wonder how blown in cellulose is installed in the states. It
always sounds as if some unskilled blokes come along with a tuned vacuum
cleaner. Thatīs how it started in germany. Clearly this doesnīt give you
as dense a pack. 
But how itīs done now, with certified trained crews only (and german
liability laws), I do not believe it settles. it is compacted to a
degree that it wonīt anymore, and I both trust in german product testing
and in my own experience, getting almost knocked off the scaffolding
while securing the outer sheathing. 
Any other insulation made with binders is way more likely to fail, as
binders dissolve over  time.
We had this topic before. Why ainīt there any american cellulose
installer who has the pride and confidence in his product to speak up
and raise the standards?
What is the density that is claimed, anyway?

yours, Alex
