1400 sq/ft of basically uninsulated attic

This picture was taken for the water damage, but you can see the spacing I was talking about in my last post.

The rafter board across the upper right of the picture goes into another board in this area (that backs up to the sole remaining in-the-wall chimney), but in the rest of the attic, they sit on top of the flat boards on top of the bricks. The roof rafters sit on top of the 2x12's.

If the plan as I read it is to use the little cans of foam, not going to happen unless you have lots of money and time.
There is 0 need for all those layers. One layer of R-50 fiberglass would be all you need. Or have a pro come in with the proper equipment and spray foam the whole thing.

Nope, DIY two part foam kit. Doing the entire 1400 sq feet in just foam is way out of my budget, whether I did it or paid someone to do it.

We're air sealing with the foam, then blowing the cellulose over it.

Look at the gold insulation. You must have a Leprechaun in the attic.

If most of it is already gone, I don't think it would be too expensive as it would just be a thorough HEPA vacuuming.

Note: If there is asbestos? In your vermiculite then it will do no harm, if you leave it alone.

Yup, I'm not worried about the possibility of asbestos. We're leaving it alone for the most part, and we keep handling to a minimum. :-)
