How to Z-Strip Insulate a Recording Studio

Video Transcript

"On behalf of Expert Village, my name is Gregg Tauriello. I'm from Sweet 16 Studio, and I'm here to talk to you about soundproofing for a recording studio. Okay, now I'm going to show you, on top of your 2x4, we have here what is called a "z channel". It's a resilient barrier strip they call it, or a z channel, for short. This can be mounted right on your 2x4's like this. It creates dead air space between your joists and your soundboard which is going to be attached to the z channel also. When we attach this with a nail or screw to the 2x4, it gives me a half an inch or more of air space. When this z channel is attached to your 2x4's, it creates a springing motion which is great for sound, because when sound hits it, it absorbs the sound with movement. On top of the z channel, we're going to attach our sound board. This goes on before your drywall, but it can also go on as an addition to your room if you already have your walls drywalled, you can do z channel and more soundboard, and another layer of the drywall. This is better, the more mass you have and the more air spaces and air pockets you create, the more sound you're going to stop from going out of your room, and the more sound you're going to stop from coming in, like cars going by, dogs barking, depending on where you live. Now we're going to attach this sound board to the z channel and I'm going to show you the next step after that."
