The man who sold my house to me didn't leave information on windows. Does anyone recognize something on this sticker that could help me identify manufacturer? I live in Arizona. I have searched the image and other sites which pointed me here.
Well, your manufacturer code is ALE(TX). However, that doesn't turn up any hits in the NFRC database. (Nor does it follow current mfr code convention.)
Other issue is that this window is probably quite old. (Sometimes you can see a manufacturing year stamped in the aluminum spacer between the two panes of a sealed unit.) Maybe it's time for complete replacement...
According to the FGIA site, since you have a silver NFRC label*, you'll need to consult the National Fenestration Rating Council's (NFRC) product directory.
I tried doing that, putting in basically every code from your label, and came up with no results (noted in my comment on the OP).
The FGIA site also indicates that you can contact the NFRC at 301-589-1776 to talk to them. It may be worth the price of a long-distance phone call (wait, what??) to talk to them directly and read the codes off of your label to someone who's familiar with how to interpret them.
It's also entirely possible that the windows were manufactured by a small, local company that was never listed with either FGIA or NFRC and may have gone out of business since. In which case, it's probably just time for a full on upgrade if that's what you're looking to do.
*I did try searching the FGIA site for "ALE" and "ALE(TX)" but it returned nothing, just as the NFRC site did.
