Integrity Triple pane glass???....

I was poking around on the NFRC website looking up some ratings, and I noticed under Marvin, they have an Integrity window option in a triple pane window. The ratings are quite good (u= low .20-23) which is quite a bit lower then Marvin's tripane, which tells me they are using fiberglass instead of aluminum clad.

Does anyone know anything about these, and if they do exist currently? I have search everywhere but can not find anything about these other then on the NFRC website.
