[Greenbuilding] primer on open cavity blow-in cellulose

[Reuben Deumling]

Are there manuals or guidelines for blowing cellulose into open
cavities--both vertical and overhead that folks could recommend? As
far as I can tell there seem to be two basic ways to accomplish this:
using a mesh/netting, or adding moisture to the cellulose and then
trimming it afterward. Any thoughts are appreciated. I have a blower,
but would need to rent the trimming machine, I suppose.
