I think the best quality glass you can get is called StarPhire, (or StarFire) or some variation or so of it. It's an incredibly low iron glass (there's not as much of a green tint to it). Unfortunately, I don't know anything about vivariums, so I can't help you about the thiccness of your tank. As for better quality glass/panel, I'd just buy enough for scraps+whatever viewing panels you'll have+where the light will be if it's a vertically oriented vivarium, and then use regular glass for the rest. Oh! You might also wanna look into shatter-proof glass if it's a vivarium?
So many fish to keep, not enough aquaria.
