windows between live and control room

Hello all! Just wondering the benefits as far as non-touching seperate double wall constuction verses a big 2x8 window sill and mounting 2 very thick laminated sheets on the single sill. How would the results compare? I appreciate the thoughts.

That single seal will pass sound from one room directly to the other. By keeping the sills seperate, you are using air to isloate the sound that would otherwise be transmitted.

I'm worried about keeping the windows clean, is there a legitamate concern for dust accumulating? Is there a decent STC rating with a single piece of laminated glass if it is thick enough?

You have not studied this forum. There is detailed info regarding windows, STC ,etc.... You want 2 panes of Laminated Glass. If you enclose the area how will dust enter into the are?????? If cleaning is a major issue for you, instead of nailing the strips that will hold the glass in place, screw them in place so you can remove a pane of glass for cleaning purposes. Although I have never heard of it being an issue...Doesnt mean it wont be one....

i have studied this site extensively. i just have access to unusualy thick glass. is there a scenerio under which you would not worry about putting the live room side pane at an angle?

It is not necessary to place the glas at an angle. With your extensive reading you would have found out the issues ralted to single anything, walls, glass, doors, etc... You are not creating a trap for the sound. If what you are after is a CHEAP single wall construction solution then by all means have at it, but if you want a properly constructed Studio I advise you to follow the 30 + years of experience by john, the xx+ experience of Steve and build it correctly. You are trying a .50 cent solution to a $1.00 problem. Dont mean to sound harsh, it just sounds as if you are seeking justification/approval to cut corners.... We cant make you do anything other than what you have planned. The advice is sound, tested and it works....

Study the forum like you're preparing for a critically important exam... It will be a test of your project, your budget, and your sanity. Don't miss my "Stages of Soundproofing Enlightenment" thread. ;-) If you're skimming the forum for information, you're going too fast. You need to slow down and let all the richness of this resource sink in so that it saturates your brain. There will be a pop quiz, so study hard! :twisted: --Keith :mrgreen:

LOL the pop will be all that sound that travels into your "iso" booth, vocal booth or other booth. :)

I appreciate your time more than you know. money is not a concern so much as dealing with the process of getting the double wall scenerio right. I understand the right and wrong reasoning, thankyou!! Why do a lot of plans and drawings call for an offset pane? Also, my contractor is concerned about attaching 2 layers of rock to a resiliant channel that is attached to the ceiling joists(this is a basement) I have read the plans by ACC Warnock in the threads, but want to know if there should be some concern?

Kudos to him for his concern about that. There are products that can handle it -- RSIC clips holding hat channel I think would be more sturdy. Even better would be staggering joists that are supported on inner walls... :roll: --Keith :mrgreen:

I can understand his concern......My ceiling in my live room is attached to RC and it is 3 layers 2 drywall, and 1 celotex....2 years later all is well...I'll followup in 10 years ;) (j/k) Offset panes are visually appealing. more so than plain old vertical panes

No - if your contractor can find Dietrich RC Deluxe, use it on 16" centers if your joists are 24" centers, and on 24" centers if the joists are 16" centers.

thanks so much, I dont have room inside room construction, so the double wall for my windows that will seperate control and live room will both be braced at the top in the floor joists. does this cancel out the isolation or harm the intented effect? thanks for your patience.

Depending on the "bracing" you use, I'm 99.9% certain it will hurt your isolation. :?

is there any solution to bracing, perhaps a better way to do it?

Any chance of a sketch showing what's already there, and maybe a second one showing what you plan to do? The more we know, the more likely we can suggest useful things... Steve

Anti-sway bracing. A few companies sell them, such as Kinetics Noise Control or Mason Industries. I'd offer you direct links, but I'm very short on time right now and both of their sites leave a lot to be desired (Mason especially so).

thanks so much!!!
