French Door replacement..who?

[idontknow]

I am looking for some comparable data / information on exterior French doors, both fiberglass and wood clad. Cost and performances of Pella, Marvin, Biltbest, Milgard or some other. Thank you.

That is precisely the sort of information that I have come to rely on from Consumer Reports magazine. You can check their website for information on doors, but since those manufacturers also make windows, I'd trust that the window ratings would probably be a reliable indicator as well.

Fine Homebuilding magazine is another magazine that does good reviews of building materials and tools. I don't know if they've recently reviewed doors or windows, but you should check their archives as well.
