Sealing the Ceiling, and the last Insulation

All things do have an ending, even insulating!  Here are some pictures of finishing the front room insulation. The foam in the wall has been sealed with spray foam, silicone and or Tuck Tape, depending on the size of the crack that needed to be closed up. It was then covered with a half thickness of six inch fiberglass, and then the sheet of double bubble reflective insulation.

I put insulation in the interior walls as well to act as a muffler to sound. The dogs have been helping me out quite a bit. Here you can see them on the job:

Upstairs is done too. It feels a little bit like being in a space ship with all the shiny silver wall coverings.

Working on the end wall.

I had intended to add another layer of rigid foam to the ceiling but changed that plan because 1) I was tired of cutting and fitting rigid foam and 2) I had to get some thinner 1 inch sheets to fit and they didn't smell very good. I decided I'd rather not risk whatever off-gassing they might do.

As with the walls, the ceiling was sealed with spray foam, silicone and tape, as required to close all the gaps between the foam and the rafters.

I then used fiberglass insulation to fill in the remaining space. This was a bit tricky as it didn't want to stay in place at all. With my father's help, I put up one piece at a time, wrapped the double bubble across and stapled it to hold it all together.

Finally, the seams were sealed, and I added a row of two by two down the center along the ridge beam as a nailer for the tongue and groove planks that will be going up next.
