Is there any downside to Low-E 366?
I live in - very sunny, hot and humid - SE.
We are replacing all windows and doors (most likely, with Marvin aluminum clad). I have been told to go with 366 for maximum UV and heat protection. I know it has a little bluish tint but that wouldn't be a big deal b/c I am repainting the walls anyway in those rooms where the windows are sun-facing.
There isn't much price difference between Lo-E II and 366.
I just want windows with the *best* rating for the climate.
