I was a little disappointed at the dense pack cellulose because the insulation contractor didn't do it like I had seen in videos and it didn't seem dense enough. I read that the installed cellulose is supposed to feel like a firm mattress, but ours only felt that way in some spots. I actually cut holes in several spots to see how well the cellulose held up and it didn't settle. It wasn't as dense as I would have liked, but I think it is adequate. I hope so in any case.
Here are some examples of the Intello Plus and the dense pack insulation. Also there are some areas around the second floor rim joist insulated with Roxul mineral wool insulation. You can see the 2" x 4" service chase on the walls, room for electrical and plumbing so it does not take up insulation space in the 2" x 6" wall space.
You can see the see the service chase in the kitchen much better here.
