Experience with Polaris / EnergyWall Windows?

Has anyone used Polaris UltraWeld or ThermalWeld+ windows or EnergyWall EnergyWeld windows made by Polaris? They have some pretty high efficiency options, and they claim good air infiltration resistance. I can’t find design pressure on their websites though.
