Marvin's Integrity or Weathersheild's Fiberglass
OK, which one, I cannot choose. I really like the fiberglass over the aluminum for strength. (as they use the fiberglass thresh hold for the aluminum clad doors) Which company would you recommend? Marvin does not offer the spacer bar inside the glass panes, Weathersheild does. Marvin WAY out scores Weathersheild in the Consumer Reports on blowing wind and wind driven rain. I like the look of them both, but am I going to wish I had the spacerbar or not, or am I going to wish I the better performance window? Help me please!!!
