Well...
you're halfway to half of "some semblance of an understandable performance spec and the local climate".. keep trying.
Hint: The better you describe the situation & your desired outcome, the better suggestions you'll get.
I'll definately look for the extra high stuff in that case, if this insulation is what I use. Mice are a big problem in my area, and I cant stand hearing them in the walls.
At least someone understands why I like that look. It all started when I built my tool shed, and I loved the look. There wont be any air gaps when I build it. There are none in my tool shed. Every joint gets a bead of silicone caulk. I mostly did it to keep water and insects out, but it also keeps the outdoor air out. I have thought about using a stain on the wood too.
Good luck with that. I'm sure there are umpty-ump regulations requiring insulation on new construction.
By requiring every new building to have a minimum of insulation, gobs of energy will be saved, lower costs to everyone, conserving precious resources, and providing jobs for legions of compliance officers.
Besides, it's for the children.
