What do you think of this wall makeup?
I’ve spent countless hours researching (new to energy efficiency,) and I’ve finally decided on a wall design for a new construction house I’m building. Curious as to what you think.
Location: CT (Zone 5)
1/2″ Gypsum Board/Latex Paint
2×2 horizontal strapping with Roxul ComfortBoard 80 (1.5″, R6)
2×6 wood studs 24″oc with Roxul R23
7/16″ ZipSystem, taped appropriately
(2) layers 1.5″ foil faced Polyiso, outside layer taped
Hardie Board siding
Effective R-value of both Roxul products: r23.42
Putting an R value of r5/in on the Polyiso: r15
R value of gyp, sheathing, airspace: r2
Total effective R-value: 40.42
I appreciate your help. Thank you.
