Just curious - what type of insulation did you use? The paper-like fiber stuff, the styrofoam beads, or the loose fiberglass? (Or something else?)
I've seen the paper-like stuff done at my parent's house, and while it looked really easy to work with, the stuff has a relatively low R value. I've actually done the styrofoam stuff myself, and I'll never touch it again... Might have a better insulation value, but it makes one hell of a mess. (Especially around the hopper!)
I've heard about the loose fiberglass stuff... Supposedly it will work with the same equipment, and it's got the best R value of the three. My only concern was loading loose fiberglass into the feed hopper. (How messy is it?) Cleaning up styrofoam is bad, but cleaning up fiberglass has got to be worse. (Styrofoam doesn't make you itch!)
