Creating more space for attic insulation
Ok, I’m sure this is a stupid question, but I really do appreciate all of the patient answers I have received in the past.
Because I will be building my home with blocks that are 1′ tall, my top floor will be 8’8″ from floor to the top of the tallest course of blocks, where the roof trusses normally rest. I really only need 8′ ceilings on that floor. I got to wondering what to do with that extra 8″, and came up with this idea to add some extra insulation since I would like to have a floor for at least part of the attic.
I was thinking that it might be possible to attach some 2x8s or something like that perpendicularly to the roof trusses along the bottom, and then attach drywall and what not to that. The extra space could then be filled with more insulation, offering about an extra R20 (minus bridging from the wood) if using cellulose. I attached a picture to try and illustrate what I mean. The yellow rectangles are the ends of the lumber that is attached to the trusses.
Does this make sense? Is it something that could be done? Is it something that should be done? Would I be better off just making the ceiling taller or cutting the blocks to size?
