• GLASS Three panels separated by pockets of argon, a common window insulator, add up to 1.5-inch-thick panes, twice as thick as standard residential windows.
• THERMAL STRUTSPairs of ¾-inch strips made of a strong glass-fiber-reinforced plastic called polyamide bridge the interior and exterior aluminum frames to keep heat from traveling through the aluminum.
• THERMAL DEBRIDGINGTwo narrow channels in the interior frame are filled with urethane, which cures in place. Then the aluminum in the bottom of the channel is cut away, leaving a urethane bridge that’s less conductive.
• AIR POCKETS A type of weather-stripping known as a fin seal, made of a synthetic material called wool pile, lines the perimeter of the sash and creates air pockets that stop cool air from reaching the inside and causing condensation in the winter.
