Thoughts on the Bensonwood OBPlusWall?
I've been a big fan of Bensonwood's ideas and innovations for some time. They recently announced their new wall system, dubbed OBPlusWall. I'd love to hear some of the GBA community's thoughts on this wall system, with the following considerations:
-Not sure exactly where the air barrier is... the Huber ZIP sheathing? Any knowledge or experience how Huber ZIP performs as an air barrier?
-If ZIP is the air barrier, and all insulation is inside the wall, does this pose a potential danger for condensation during the heating season? I suppose that if the air barrier is tight enough then it shouldn't be a problem.
-Any idea how significant thermal bridging is with I-stud wall construction?
-Could a Passivhaus be built with these walls?
