Greenhouse glass: chemical structure and production?

Hi!
I’m a chemical engineering student. I’m loking for information about the chemical structure of greenhouse glass and how it is produced.
I used google to search but all links were devoted to commercial greenhouse. Is there anyone who shows me some useful links?
Do you know any books about that? I don’t know if New York University library or NYC public library have the books you recommend. But, anyway, just let me know.
Thanks in advance,
Minh Tran
