Pella's Frech Gliders are crap -- the metal cladding comes off and water goes in and rots the wood. Ask me how I know.

(PLUS the bottom of the gliding panel isn't sealed, so the wood just rots away.)

The new Anderson Frenchwood is good except for the "water well" -- or whatever they claim it is...

Oh. Did you mention Pella Window and Door Problems?
