Confused by my topic title ? 
ill try to explain as My cabin shed is 32x12, with lofts. The lower 7 feet is stick built normally , but in the loft on the end walls (12 foot short side) the 2x4s were turned sideways where the gable windows are.
The choices as I see them are
1. Attach another 2x4 to each of these to bring them out for 3 inches of insulation.. BUT this will remove another 1.5 inches of insulation that can touch the ceiling up there in the corner, as well as remove 1.5 inches of air channel space for ridge vent air flow.
2. use 1.5 inch foam board cut to shape and great stuff around its edges to get R6 or R7 on the loft end walls, and allow insulation up in the ceiling corners
heres a picture of my loft area in question, im just not sure which method would give best overall cabin rvalue.
Any advice on this ?
Oh, well while im talking about loft insulation I guess ill toss this question out there too. One of my lofts overhangs 4 ft of porch, between the porch ceiling and loft floor there is 6 inches of space. I want to insulate that space obviously but I cannot remove the porch ceiling. So I was going to remove the loft plywood floor instead but then ran into another problem. They used twisted shank nails to put it down and for the life of me I couldnt get them to pull out. What do you recommend ? I was thinking i could just skillsaw a 2ft wide channel down that 4ft of plywood space and slide in batts then put the sliver of plywood back over the joists, think that sounds ok ??
Thanks again

2 would work.
Whatever you do think ahead to what is going to be used as the interior fonish wall and how that will be attached at the corners. You may need some extra something in the corners to nail to.
Make cardboard patterns to make it easier to get the foam sheet correct. Maybe even apply an extra thin sheet across the infilled space fpor a little extra if you want

Thanks don, ill have to trim the end wall with some 1x2s i guess so ill still loose some ceiling room, but what I think ill do ( tell me if its a bad idea ) is trim my air gap in that last 6 inches so I can fill all with insulation, the ridge vent isnt open on the last 6 inches anyway.
It might make things easier if i finish the drywall end first then put on the 1x2 and finally finish the ceiling

No expert on insulation but what about renting a blower and drilling the required holes in the floor and blowing in the insulation? I know the hardware stores have the DIY kits for this and the area is small.

I wish, but thats not an option for me. The local building supply store doesnt rent them, nearest home depot or lowes is an hour away and I cant fit the thing in my car.
