all the above, spray foam seems to be it these days but Im not sure about the long term. I dont like how they are spaying it on the roof decking and rafters now without any obvious venting, sure it makes a nice attic. If you did conventional batts with it would be nice. What concerns me with the foam is open cell or closed? And how the fuck do you find a leak? Times change and I dont keep up, if I was building today I would prob put foam board under decking and vent roof and use batts with cellulose on top if affordable.

>put foam board under decking and vent roof and use batts
Yes that works nicely, we used to do it a lot on commercial buildings, up to four inch foam boards.
