Sprayfoam...

So the city required me to get sprayfoam on the angled portion of the ceilings because it's technically considered an attic space, and that needs a very high R-value.  The sprayfoam doesn't meet that with 2x4 rafters, but they said it's fine since it's the highest that's reasonable.

And of course that means I have to take down the drywall that I already put on the ceiling in here to have them spray it in... That included the ceiling as well because they needed to spray an extra 2' up to prevent ice-dams on the roof in the winter since at the point where the flat and angled ceiling meet, the cellulose wouldn't provide a very high R-value.  I don't have any pictures of this because it was annoying to have to remove the stuff I put up a year earlier with my Dad.  Funny enough he helped me deal with all the cellulose as well.

Overall the process was pretty cool.  They used the low pressure sprayfoam instead of the high pressure since it wasn't that big of a job and it meant I didn't have to leave my house for 24-48 hours while it offgassed.  Still cost me $3k though...
