Dose this sound right...4x8 rafters on 32" centres/ then 1" tongue and grove  5 3/4" wide/ then 6 mil plastic sealed with acoustic caulking on seams/ then 2x5 1/2 on edge to hold 6" cellulious batts in place// then capped with 1/2." Plywood/ then tyvek roofing paper, / then steel roofing
Cabin is 24x28 without the overhang, ridge beam (8x8),

This is the way I'm leaning right now, after numerous other suggestions, including sm board, Rockwell insulation, silver board, blow on foam, and sips
This is a bush camp that will be used year round, which would intail warming up in the winter then letting it cool off then possibly back following weekend all over again heating cooling numerous times in cold weather, camp will be heated with a wood stove
Thanks bic

Bic , Make sure you have air movement above the insulation and ventilation . I live in Hanmer and my Phone # is in the phone book . Call me if you like . Joe Beynen

@bic, that sounds pretty close to what I am planning for my cabin in Alaska that will see regular weekend use in the winter.  My plans right now are 4x8 on ~35" center, 2x6 T&G (or whatever I mill), ice & water shield, 4" of XPS foam panels in staggered 2" lifts, 1.5" of 2x4 on flat to secure the panels, then strapping and metal roofing.  I may add in plywood and felt if needed prior to the roofing.

Just make sure the 4x8 rafters are sufficient for your roof design snow load.  One thing I'm learning about small cabins and wood stoves is that there really isn't a lot of need for extreme insulation.  A good stove banked for a slow overnight burn will produce way more heat than is needed, in most cases.  It's a little different than a house occupied full time.  For a weekend winter cabin you want a big enough stove to warm the place up when you first arrive, but you don't want the place to remain a sauna once it's warmed up.  I understand it can be tricky finding the right balance.

Thanks for getting back to me fellas, it's something you don't want to have to redue in 10 years, Joe I gave you a call and left my number on your answering machine, was gone on a moose hunt for the past week, and just got home.

How did the moose hunt go?  I was out for a week at the cabin property and we saw neither moose nor caribou.  The wolf pack in the area probably had something to do with that.

Hunt was good, got a good look at a bull, but as luck would have it had a cow tag, movement really picked up mid week, just right place wrong time, saw one young timber, Lynx and kit, bear ( little closer than I needed) lots of grouse and couple meals of pike and wallys. Hard to beat

[ChugiakTinkerer]

Yes indeed, hard to beat.  I found the hot hole for grayling at my lake and we enjoyed fish tacos for lunch one day.  Best way to see a bull is to have a cow tag.  Had a nice bull broad side at 30 yds in an open field on a bowhunt once, with only a cow tag in hand.   :

Back to your original topic, how many posts have you got supporting your ridge beam?  You may be able to reduce interior posts by going to a 8x12 ridge beam.

4 posts supporting the 8x8 ridge beam, had a change of heart on the plan, there were so many different ideas from different people, I took advise from scouter Joe who was very helpful, and is probably tired of hearing from me, decided to go with a spray foam application little more money but I think it will be worth it in the end.
