Hey, just bolt it on and call it good! marginally more stylish than stucco. waiting for some maniacal AT to figure out how to attach full-wythe brick into these bad boys or something crazy.
IDK i think it looks good, simpler to install than traditional curtain wall, the smaller glazed area on this probably helps a LOT with meeting envelope RSI requirements. Given the current (2017) NECB basically calls for 30% glazing max (or high-performance glazing to make up the difference if you have more than that) i bet we'll see a lot of this kind of system moving forward. I kinda like this!
