There isn’t really a single right answer, it depends on a lot of factors and what your priorities are. From a sustainability point of view, we tend to point people towards insulation materials with lower carbon footprints, high recycled content, reduced chemical content, etc. In our last couple of builds we have used mineral wool insulation (common brand association being Rockwool formerly known as Roxul), and dense packed cellulose.

What is the best insulation for a home?
There isn’t really a single right answer, it depends on a lot of factors and what your priorities are. From a sustainability point of view, we tend to point people towards insulation materials with lower carbon footprints, high recycled content, reduced chemical content, etc. In our last couple of builds we have used mineral wool insulation (common brand association being Rockwool formerly known as Roxul), and dense packed cellulose.
Very important along with which insulation you choose is proper installation to make sure it lasts. To that end, I would recommend reading about how to install siding so walls can dry, also read about the importance of air barriers for energy efficiency and durability. If walls are not built with airtightness and an ability to dry, they are at a far greater risk of developing mold and they will not perform as well.
