I have signed up for "Weatherlok" energy efficient windows supposedly manufactured here in the Dallas, Texas area. All I can find is a company in Welcome, NC which is also involved with "Arium" windows. Guidance to fine information on "Weatherlok" windows, please.
Weatherlok is a window replacement line manufactured by Atrium. Atrium is a large national manufacturer. They manufacturer windows under several different names. They might have plant in Dallas but they do have a large manufacturing facility in Welcome, NC. I would guess the windows would probably be coming from NC.
