Recommendation For Studio Glass

I know this topic has been discuss (at length) - but I would like to know what some of you would "recommend" for studio glass. I will have two(2) panes of glass - one for each wall in a double-wall system. Specs are as follows: Window: 6' long X 3' high Double wall - made from 3.5" metal studs with 2 layers of 5/8" on one wall and 2 layers of 1/2" on the other. Question: 1. What thickness (for each pane) would be optimum for these dimensions? 2. What "type" (tempered, laminated, insulated, etc...) would be the best What I mean by "The Best" - is, what do most people, or the pro's use? Any help would be greatly appreciated....

In reading everything here, the most common is to use laminated w/ 2 different thicknesses of glass for both sets of windows. I wouldn't use insulated, as this actually creates more problems. And tempered would probably be more of a codes issue in a commercial facility in some area's. Plus, w/ tempered you would have to have it measured exactly, since it's heat treated and can not be cut. So I would say laminated.

Agreed; thickness should be AT LEAST 1/3 the gypsum thickness in each leaf. So, if you have two 1/2" gyp in one side that glass should be at least 1/3", meaning you'd need 3/8" - the two 5/8" gyp side totals 1.25", so minimum .4", 1/2" would be the choice. With that size panes, more wouldn't hurt; so if you can afford it, use 1/2" and 5/8" to be SURE the glass won't be the weak link in your wall... Steve

Thanks Guys... Appreciate it.
