Thermal control is achieved using 1-inch (R-3) Zip-R sheathing on the walls and roof to limit thermal bridging. (Note: In colder climates, thicker foam would be needed for continuous insulation.)
The author fills the cavities with blown-in fiberglass.
In attic areas, he drapes the netting to create a “bag” that can be filled with more insulation than the depth of the framing would otherwise allow.
