Normally the bridging would be reduced with an inch or so of XPS or EPS affixed on the outside of the metal studs (or, more likely, on the outside of the sheathing) and covering all exterior walls. Then house wrap or a drainage plane. The outer cladding (siding, lathe and stucco system, etc) goes outside of that. Drywall goes inside and is required as an ignition barrier.Regarding the use of EPS in this type of construction and the objections raised to it: How does this system below get around those? Like the thermal bridging where the edge studs meet?
This outer continuous foam insulation layer really improves thermal efficiency of the structure, and I believe it may now be a code requirement in many places for wood stud construction, too. Old time framers don't like it because it complicates window and door framing, etc.
ETA: The marketing video also didn't show any shear panels that would resist wall racking. There would need to be sheathing or diagonal bracing/straps to accomplish that. Doesn't show the real world details of electrical runs, piping and DWV, etc either.
