Hi All, I live in sunny Florida and I'm replacing my existing sliding doors. Someone on the board once recommended ODL brand sliders, and they seem to be quite good quality. My question is: French Doors or Sliding Doors? Is there a distinct energy conservation advantage to one over the other nowadays? Are the sliding doors rolling hardware really susceptible to breakdown like I've heard? Other than ODL for sliders, any recommendations for manufacturers or either French doors or sliders? Thanks!
