Hi again, Dan. It must be nice to know what you don't know. Sometimes I don't know what I don't know until it's too late...

Specs on the cotton insulation look very good. It's manufactured for a friction fit, and because it's in batt form rather than loose, it won't settle. The addition of borates acts as a nontoxic mold, mildew, insect, and rodent repellent, and gives the insulation high resistance properties to fire and smoke. Supposedly, it dramatically reduces airborne sound transmission from such things as airplanes, TV,traffic, conversations, etc.

I wonder what it does for rooster hollers?
