During my afternoon roam (in the sunshine!!), I spotted several buildings under construction, with this green exterior sheathing. Eye-catching green* sheathing.
Apparently, it’s all but replaced plywood and other engineered wood products for this purpose—at least for commercial buildings.
Or that’s what Zip System’s manufacturer would have you believe. Apparently, a big part of the superior qualities of the green-board lies in the breathability and air-barrier capabilities.
* Frooogy green?
