Good read, although the one discussing insulation factors of fiberglass bat insulation opens up a good discussion, "If not fiberglass... What?"
What would be the preferred method for off grid cabins? I was going to go bat insulation with a full 1" sealed thermal break on the outside. Thoughts?

Fiberglass batts are fine, and they are probably one of the most cost-effective forms of insulation in the US. Add an inch of foam board on the outside and you will be good to go.
If you read the associated article, "Should Batt Insulation Be Outlawed?", the authors problem is not with fiberglass batt insulation itself, but the poor installation that contractors often do. As long as you do the work yourself, you can be sure that the installation will be done right.

The reason fiberglass is used by so many people is because its easier to install and most people can do it as a weekend project. But installing it right is another thing. If you take your time and work it into the area and dont over compress it you should be fine. Now is it the best bang for your buck I personally dont think so. When I built my cabin I put in dense pack cellulose it gives you a better R value and it seals all the little cracks. It is becoming more popular and used in more new construction in our area.
I know everybody is going to say you have to have a special blower and all the right equipment, but if you take your time you can blow it in with regular cellulose blower and achieve a quality job and its not that hard. The biggest task will be finding the netting. I personally will not use anything else after seeing the results in my cabin

Quoting: Nate R Mineral wool batts.
Roxul roxul (mineral wool batts) are fireproof and rodent resistant. They can also get wet and dry no problem. Very easy and safer (than pink) to install. etc.
Polyiso, is for foam, made with lower or no "bad" foaming agents. It also has the highest R value. and tin coated is good for reflective "cool roof" use.
XPS also has a great role to play as it is waterproof. But note that the foaming agents are not benign.
EPS I avoid.
Quoting: 1tentman take your time you can blow it in with regular cellulose blower
thx 1tent. I haven't done cellulose and a lot of folks around here look at it and then get scared off by the "difficulties." which are usually finding someone who has done it before.
