My scissor trusses are arriving this week for a detached studio I’m building (in Montana). And I’m thinking ahead to how I can get r-38 insulation up in the ceiling, wondering if there’s away to leave the trusses exposed, without having to finish the ceiling with drywall. I have ordered the trusses with a raised heels to help insulate above the top plates (about 8″). If I go with rigid panels, my understanding is that they mount directly beneath the roof sheathing and I should not vent the soffits or ridge (“the warm roof”), but then think this may be the most expensive option material wise (planning on doing labor myself as with most of the building). I’m also considering batts or stick pin insulation, but not quite sure how the venting would work if I dont have drywall underneath the insulation. The other question is, is there a batt product that can mount directly to the roof sheathing that would work in similar fashion to the rigid, where no venting is required. Is there a way to make it look good in a unfinished ceiling sort of way (i.e white faced stick pin or somehting similar?)
