I don't doubt Andersen makes a decent product, but I'm skeptical of
vinyl in general.

Over time, after a beating from wind and rain, I think aluminum will
hold it's shape better than
vinyl. There are examples all over my neighborhood of vinyl windows
coming apart, not even five years after installation.
Granted, they aren't Andersen.

I'm open to persuasion, though.

I have 4ftx6ft vinyl gliders in my home, circa 1990, in the NE, no
problems, no whistles no cleaning[or even washing, or is that TMI] and
they open no problem. they were bought through a neighbor who sells them
and siding, i bought one more for an addition, and I shoulda bought all
of them there as they cost a fraction of the Andersons the architect
spec'd. I 'think' the guy has a Marvin sign up, but there aren't any
labels on the window that I have noticed
