Exterior Insulation
Sided and sheathed exterior insulation at gable end from foundation to shop fabricated gable vent.
Dense pack cellulose fills the stud cavities on the interior side for a total wall R 45 insulation
value. 20″ of loose pack cellulose above 2nd floor ceiling joists provides a R70 insulation value.
Triple pane windows (as shown in photo) with reflective coatings (LoE) on glass surfaces separated
with argon glass (R6) are critical part of thermal envelope.
