And Rick, you know too much! Haha
Well, its what I DON"T know that bothers me
As far as the regulations and all that good stuff, I believe it's all being taken care of by the land lord,
You believe? How does one apply for a permit when he DOESN"T even know what he's building?
Cult_Status02, I think you are very naive and are fooling yourself, that is if you REALLY want to stop the siren noise from entering the mics. Insulation will ONLY help a little, but requires MASS and lots of it in order to do its job, which is basically absorb hi and mid frequencys within the stud cavity and dampen the drywall. Other than that, it offers very little in the way of sound transmission loss.
If that doesn't work...lots of foam on both sides of the walls! lol.
Thats rediculous. Foam does absolutely nothing for transmission loss. Besides, if THAT doesn't work, you've already wasted time and money

And after the fact retrofitting of work that does nothing in the first place is throwing bad money after good.
I think maybe with the new windows, and that fact that it's basically a whole room inside another room,
Wrong again. Your room within a room" is nothing but partitions, with the framing structurally TIED to the existing structure. This is NOT a room within a room. All you've done is partition off space. You could put 5 layers of drywall on BOTH sides of the framing, and sound would simply flank via structural transmission through the existing floor, cieling and new framing tied to it. I guarantee it.
In order to build a TRUE room within a room, it must be a complete DECOUPLED envelope, floated on resiliant isolators and isolated sway bars. When building a project such as this, it would help if you READ how to go about this first, instead of flying by the seat of your pants. Unless you're Bill Gates and have lots of money to burn. If you ACTUALLY interested, say the word and I'll post some links to info that will REALLY help you. Otherwise, send me the money you will waste, and you keep the time as I can see from the picture you are already on that path.
