B-CORE slab. Honeycomb like construction panel

But there looks to be an actual technical innovation here: a new way of manufacturing metal panels with properties similar to honeycomb panels.

Is it really so hard to look past the marketing nonsense for a second and consider the product on its merits?

As for moisture, this is stainless steel, so it's inherently fairly corrosion-resistant, though I'm sure there might need to be mitigations put in place (e.g. a coat of paint or sealant at the edges) in some applications. I guess the ends might need to be plugged to protect the copper.

A traditional honeycomb panel has to be brazed by baking it in an oven, or otherwise applying heat from outside. With the b-core construction, there is space between the tubes for air to flow, so they can shoot superheated air through the interior to braze, which apparently has advantages in speed and uniformity.

Looks like an investor fleecing operation.

I helped build a place using "foam core" enameled steel panels in the 1980s; its still there but they had to do another layer of siding over the outside after about a decade, as the paint was beginning to chip and bubble. The "foam core" stuff turned to powder within a few years and settled at the bottom of the panels, meaning what insulation value they had is almost completely gone now.

The marketing speak for those panels had a very strong resemblance to this stuff.
