What's up guys. Building a vocal booth in my 19x9 studio on a $2000 budget. Been reading through some of these threads for a couple days. Nice info and build here.
I have a friend that did all the design work in CAD. I'm trying to locate the best deal on the glass. First, let me give you a run down of whats getting done. We're build a double wall booth with a 2" air gap between the inner and outer walls. The interior size of the booth will be about 7.5'x3'. So the glass will be very small and I don't want square. I'm thinking of going with size 36x30 and mounting it long ways. I want 2 sheets of 3/4" think glass. So I want to know if anyone knows a place in the tri-state area that has good prices. I live in central New Jersey. I called a local place yesterday and they gave me a price of $405 per sheet at this size. Sounds really high to me! I was thinking more like $500 for the pair. Even willing to shop online.
Here's the design! Glass started off huge, but we reduced it due to the small interior wall.
you want to match or exceed the mass on your wall but two 3/4" would seem too much in this application. depending on the overall construction, it doesn't look like you have a double wall, maybe just a single 3/4" will work. you should build the room inside-out w/ 3x drywall on the outside and use the inside framing to hold your rigid insulation and cover with cloth. this will preserve the very narrow depth you've created and add significant absorption.

Well it is a two wall design as you can see in the first two blueprints. It's just not shown in the renderings. So I will need two pieces. Thanks though!
As Glenn already said, there seem to be some conceptual issues with the design, or maybe they are just drawing issues, and maybe you should look into those first.
But either way, as Gleen also said, it is unlikely that you'll need 3/4" glass on both sides. The reason being that the surface density (mass) of the glass should match the surface density (mass) of the rest of the wall. In order to need glass that is 3/4" in thick, that implies your drywall is at least 1 3/4" thick, or about three layers of ordinary 5/8 drywall. Is that the case?
I'm not saying that you can't use that glass if you want to: it certainly won't do any harm to use glass that is thicker than you need. You'll just end up spending more money than you needed to.
Another key point is that you should aim for about an 8" air gap between your inner.leaf and outer-leaf glass, and it's hard to see how you can do that if you only have a 2" gap in your wall.

The dry wall is 3/4" thick. It is a double wall design. The first two pictures I posted shows the actual design accurately. The renderings are just to show the desired look of the final design. But the designer picked 3/4" glass because the drywall is 3/4". There's just no room for an 8" air gap between the walls.

Then he does not understand what he is doing! You don't need to maintain the THICKNESS of the leaves, you need to maintain the SURFACE MASS of the leaves. Glass is roughly twice as dense as drywall, so you need roughly half the thickness of glass to keep the same surface density. If you only have 3/4" drywall on your wall, then you only need 3/8" glass. So you could use 1/2" on each side if you want. 3/4" won't buy you extra isolation, since your wall is isolating less than the glass. It won't HURT any either, if you really want to go that route, but it won't do any extra for you. 1/2" on each side is plenty.
