Do you use tempered glass for kitchen cabinet doors?
I agree with keshlam &amp; it's definitely not overkill. I haven't run into any tempered glass paneled doors for uppers, except my own. Tempered is required for anything within 18" of the floor. And, most cabinet makers will tell you to go get regular glass to put in the empty frame doors they ship.

But, I'd (&amp; have) go for either Tempered or Laminated Glass if possible. Laminated Glass is regular glass glued to a rubber membrane to retain the glass, you're local glass shops may have this to custom cut for same or next day pickup. So, no big shards hurt or kill someone if something happens, like an earthquake.
