For one thing, the mass of glass is about three times that of drywall.
So if you are trying to match the sound proofing ( how little sound transfers through) of your glass with that of your wall build, 1/8 glass will give you the same sound proofing of one layer of 3/8 drywall... not much by any standard.
If all you are doing is creating a vocal booth where you are just trying to keep computer fan noise out of the booth, that would work.. That is about it though.
You are wasting money if you spend the time and effort to have 2 layers of 5/8ths drywall (1 & 1/4ths ) and then only match it with anything less than about 3/8ths glass (equivelant to about 1 & 1/8th drywall).
Otherwise it is like building a room but leaving the door wide open when you play.
Like I said, I have some questions but Rod has gone.
I inquired about glass yesterday. The price was not as high as I thought, BUT, the man in the glass store says things contradictory to what Rod says.
Rod talks about laminent glass. The man in the store says there is no such thing. There is laminent and there is glass, NOT laminent glass.
I can get 1/2 inch "laminent" for 25 psf. BUT, that is for what the man in the store called "laminent". I got a feeling this is not the same thing as Rod talks about in his book. I also fear that when and if I ever find out EXACTLY what I need it will be 10 times the price. Which puts me back at suare one.
If that happens then I might as well record with the door open as you put it. It will not be the first time I've had to do that. At least I will be isolated from the outside.
So, once again, the pros here use terms that the people in the real world don't understand. This confuses amatures like me when we go shopping for materials. We then have to delay our prodject and come back here to bug the pros for advice of which we feel greatfull for frustrated at an guilty about all at the same time.
