Poor man’s continuous insulation (CI)
I recently saw an interesting approach to continuous insulation (CI) that might make sustainability more affordable. Simply nail 2×2 horizontal strapping to the inside of the studs.
I’m in Georgia so condensation is not a big issue. I attached a sketch showing polyiso bands at the top and bottom of the interior wall strapping to support the gyp board. Also offset the rim board 1/2″ to accommodate a little polyiso CI.
This probably doesn’t meet IBC’s definition of CI but it could be an affordable way to improve insulation. If you are trying to reduce petroleum based insulation, it could make batt or loose fill alternatives more effective. Still have to make sure the envelope is well sealed.
