Starting at the back end, literally: The knob and tube wiring I discovered yesterday is disconnected; it isn't live. The receptacle I thought it served is wired up with standard white three-wire cable. Nice not to have to be concerned about that.
Does that mean I was wrong about the whole project? Not at all. The batts were definitely damp that day in mid-September, and dirt is a classic place for mold to lodge in fiberglass insulation. And with the facing paper hanging in tatters in so many places, the vapor barrier was grossly compromised. I would rather not spend the money on this at this time, but it'll be money well-spent.
I was wrong in thinking the batts were held up solely by the lath battens that ran horizontally from rafter to rafter. Yes, they gave some support, but mostly the pink stuff stayed put by means of staples-- lots of staples-- driven though the kraft paper wings into the rafters. So I didn't have that stuff falling down on me, either. Very glad to be wrong in this case. And I was wrong in planning to roll up each batt in a piece of .5 mil plastic before I put it into the 55 gallon black bag. I tried it once, on the first piece I took down, and the plastic got woefully out of control and simply would not stay put. So I gave up on it and just rolled the batts in on themselves, taped them with cheap masking tape, and stuffed them in the bags.
Speaking of the bags, it's good that the insulation guy was wrong in predicting I'd end up with thirty bags of the stuff. Nope. Four bags of insulation and one of cardboard, small pieces of batten, and dirty dropcloths.
In fact, speaking of the cardboard again, I found vestiges of heavy cardboard nailed to the underside of the rafters (which I found about impossible to remove, by the way), and I strongly suspect it was used to contain the rock wool that used to be in the roof.
There were some things I was wrong about that I don't find so gratifying. The Tyvek suit was a success, overall (pun!), and getting one that fit me by ordering online was the right way to go. But I wish I'd gotten the gloves with the longer arms to them. The 12" cuff kind I got you'd think would be long enough. But the sleeves of my sweatshirt kept pushing them down, and they would creep out from under the elastic cuff of the suit. I did pretty well at keeping fiberglass itchies off my skin-- except for that half inch of so at my wrists.
But getting the headlamp was a fine idea; really, the only way to go, even though it barely perched on what was left of my forehead. From the packaging I'd expected the batteries to last only five hours, but they kept going a lot longer, and are still good now.
They finally teetered on the edge of the gutter and rolled down, taking their sweet time about it. Meanwhile, I saw that my thirteen-year-old calico cat had taken advantage of the open window from the guest bedroom to hop out onto the roof and do a little exploring of her own. Happily, I had no compulsion to go lunging after her. I slithered back up the way I came and called her to me once I was back on the sill. She came, but changed her mind at the last moment and veered off. Too bad, my girl! and I picked her up by the scruff of her neck and hauled her safely in.
I have the same question about the rock wool in the far southeast corner behind the lefthand closet. There's a little triangle of space with insulation blown into it; will they foam that, or do I need to create a barrier to separate the two?
