Yeah. Kind of a tweener climate. We have had some really cold snaps of late by us where some folks are opting for the most efficient glass. That said, you definitely want a lower air infiltration, but any of the Okna's will mostly give you that and will be worlds better than the vast, vast, vast majority of other windows.
