Interesting article. 6 years ago I put in Marvin Integrity Ultrex fiberglass windows with the optional LoE3 glass since I am in the desert Southwest. The windows are very quiet and the LoE3 really works great with very little heat gain from direct sunlight. As quiet as the Marvin windows are, the STC rating can only reach 30.
But they are affordable, I got 7 windows, insulated double panes, LoE3 glass, Argon filled, custom pane dividers for $3,355

Installation not included and was lumped in with the remodeling cost.
