Perhaps the most amazing thing about the insulation is that a lot of my house didn't have any. They didn't do insulation back in 1895, I guess, and no one bothered to add it afterwards. The house is going to be so much more energy-efficient when we're done.
In this pic, they've punched holes in the original plaster walls on the first floor so that they can blow in the cellulose insulation.
Here you can see the tubes they use to blow in the insulation (from a big truck in the street), and the utter disaster the process makes of the house. Can you imagine trying to live through this?
After it's blown in, they smooth it, I guess? Or pack it? I didn't see this part.
In the roof, they use a different kind of insulation. Umm...I knew what it was called, but have forgotten. It looks disturbingly edible, like cake frosting. And/or alien.
Warm house, yay!
