Insulation
With the inside down to the frame, and the (darkened) windows ready to be covered over, it was time to mask things off.
The idea was to cover anything and everything that we didn't want closed-cell poly-something insulation stuck to. This included the floor, the windows we wanted to still see through, and the frame ("ribs") in the ceiling - had to be able to see those so they could be used as a depth gauge when cutting/grinding back the insulation, to have it only be as thick as the ribs in the ceiling. Covering the surface of them with blue tape saved a lot of time.
Some cool, but toxic stuff. After the photo, I was invited to enter and check out the result. It quickly became apparent why they were wearing those masks. (Cough, wheeze, bleeeech!)
After they were finished, I spent around 6 hours with my hands above my head, holding a wire-wheeled grinder, trying to get it to follow the contour of the ceiling as best as possible. I thought my arms were go fall off. Result: The World's Largest Snow Globe! What a mess.
The end result looked pretty good, though. The foam should help to seal up any (tiny) leaks in the ceiling, added strength to the exterior aluminum skin, has a little dampening effect on the sound, and will hopefully keep some heat in/out.
The windows that were blacked out also covered over pretty good, too. These would later be covered up with plywood.
An interior wall was going to intersect this window, so a piece of wood was used as an edge to spray the insulation up against.
As mentioned on the Demolition page, I discovered the lower walls (beneath the windows, that had metal and fiberglass sheets over them) contained, in fact, a type of foam-board insulation, installed at the factory.
