Z-girt, insulation board, and metal siding
I’m building a cabin out of Faswall hybrid ICF blocks and plan on adding an additional 3″ of Roxul Comfortboard on the outside wall before installing metal siding. I had planned on using one layer of 1.5″ Roxul then screwing 2×4 furring strips in place with an additional 1.5″ of Roxul in between the furring. But wouldn’t it be more efficient to just use metal z-girt strips with a 3″ web to support both the Roxul and to mount the siding to?
I’ve been digging around trying to find the right product for exterior use in a heavy enough gauge to support the metal siding but am having a hard time finding the right product. Am I missing something here or does it make sense to use the metal z-girt?
