Wall insulation 75% complete

Only two more panels to go-- the small ones in the back.

I did one today-- the one where the battery box is. Took about 2 hours-- I had to remove the battery box mounting brackets, move the battery box around, and unscrew the inverter and then screw it back in.

The rails for the roll-up door in the back, attach to the panel via pop rivets, so I couldn't remove the whole panel. Instead I bought a circular saw, set it to 3/8", and just sawed the thing in half across the top, right under the rails. I slipped the insulation underneath and that's that. It's in. It's ugly but so what; there'll be a drop ceiling there hiding it. I covered it in aluminum tape for now.

It's a lot quieter but I still might need some more sound insulation. I'm thinking maybe cork, or some special cork-like stuff that a local lumberyard suggested. I bought a bunch of luan, and I'll throw some clear varnish on that, then put it on top as a finishing paneling whenever I get done with the insulation. Then I got my walls. On to the floor and ceiling next. When will this be done again?
