what zone to expect if I were to enclose this area in 1/2 inch
tempered glass? This was the discarded glass for old display
cabinets.

Minimum temperature here is not usually 0 degrees f.
coastal zone 6.

thats 1/4 inch or so, thick-ish like, sorry

Thanks for being allowed to imagine. :-) What you're proposing is a
sort of cold frame or greenhouse. I've never noticed any stats on how
much those change 'zone' ratings -- just that they permit growing in
advance of the regular season. The one drawback I see, if you're
thinking of a permanent arrangement, is that it might, well, *will*
broil plants in warm weather. Depending on construction. A glass
enclosure will dramatically raise the temperature on a sunny day --
good in winter; not so good in summer. So if you do this, make it
modular -- able to be vented in transitional weather, and removed
enirely when it's hot.
