One thing to think about is resale - which product is better for that.
In my neck of the woods, AL doors and windows go on mostly lower end
homes - exception being clad AL. A lot of higher end homes are using
the better vinyl windows. Unfortunately there is a lot of vinyl junk
out there. One of the better pure vinyl windows/sliding doors in
Vinylcrest's top line. Beware they also make a lot of builder crap
also. Kolbe is mostly builder crap.

I really question the durability of wood clad with either vinyl or
aluminum. Most of it I have seen is not sealed on the unseen surfaces
- windows sweat - wood soaks it up and then you have mildew and rot.
What is a person to do.

Oh I would specifically avoid any local vinyl/aluminum fabricator -
they have all kinds of deals with local installers. Find your own
installer - when you go through someone like HD - they take 40% of the
installation up front leaving the installer scraping to make a living
from what is left forcing him to cut corners to survive.

good luck
