Insulating a cathedral ceiling
What is the most economical way to insulate an 8/12 cathedral with 2×6 rafters, 1×4 “sheathing” with 4″ gaps, no barrier…you can see the underside of the metal roofing? The roof is in good shape so I don’t want to remove it. I can fir the rafters and vent if necessary but would rather not vent unless necessary. I plan on installing a wood celing without drywall. The house is in Charlottesville Va which is mixed humid. Sorry if you already answered this but I couldnt get back to the other place I asked it.
