any advice about insulating walls in an old house?

i'd like to not have to tear out the interior walls. foam products inserted from the top might expand too fast and not make it to the floor. someone suggested pouring in vermiculite between the studs. i'd really appreciate suggestions/advice. thanks, robin

Do I need house wrap under exterior wall rigid foam ?


Do I need to put house wrap ( Tyvek etc) between exterior 3/4 "iso rigid foam (taped)? Can I go naked or just 15 lb felt?

I'm looking at tech drawings on the site and it's not shown.

My guess is not, but why not ask before I go through all this an d do something dumb.

High-performance insulation in cathedral ceiling

I'd love to hear feedback on the most efficient and cost-effective way to insulate a cathedral ceiling constructed with scissor trusses (residential construction). I'm considering having the trusses built with 16" or 20" heels and blowing in cellulose to achieve the insulation levels desired. Another option could be spray-foam (closed cell). I'd love any feedback, i.e., pros/cons to each or a better method.
