I have not seen the show, but I know that a few manufacturers are starting to offer double-pane's with U-factors in that range. They seem to have very low(numerically) SHGC's though which won't do well in a cooler climate. As for the plastic strips, maybe it's a pre-manfactured piece that snaps into the accessory groove. A lot of manufacturer's offer something like that... If not, I don't know. Could be something wild and crazy that we've never heard of!
