Hi all, I’m renovating my room and I want to take advantage of that by going the extra mile to make this room more resistant to sound getting in and escaping. This person gave me a pretty detailed step by step and I just wanted to confirm that everything checked out before I bought anything. Seems a bit overwhelming, not going to lie.
"So, you’re tearing down a room and want to make it soundproof! Let’s go into those steps! (We’re using carpet glue because it actually does a better job than green glue and it’s WAY cheaper)
**Flooring**
- Safe N Sound
- Joint Gasket Tape
- Plywood
- Carpet Glue (I like 6700 Roberts)
Add joint gasket tape to each joint along where the flooring goes on top. Then add your insulation. Next step is to add your plywood, since this is used as the under-flooring for most homes. But don’t nail or screw it in! Part of soundproofing is not only mass, but also separation! Add the carpet glue (in the same manner you’d add green glue, see image). Then add a second layer of plywood.
Once you give it 30 minutes to set, you can add whichever top-flooring you’d like, either carpet or hardwood, it doesn’t really matter.
**Walls**
- Safe N Sound
- Hat Channel
- Whisper Clips
- 5/8 Drywall
- Carpet Glue
- Drywall screws/mud
Now your walls are down to the studs as well! Add your insulation, and then add your hat channel. The whisper clips will attach on to them and add the separation we talked about earlier. For installing the hat channels/whisper clips, check out this guide <https://www.tmsoundproofing.com/products/WCR/WCR_Install.pdf>
Now add your drywall and screw into the whisper clips, NOT the hat channel or directly to the studs. Add carpet glue again, and once more, add a second drywall layer on top of the first. This one will stick to the first, with no screws needed.
**Ceiling**
Repeat the wall section.
**Finishing up**
- Acoustical Caulk
- Solid Core Door
- Door Gaskets
- Door Bottom
Add acoustical caulk to EACH edge of the room. A solid core door is also a must, because that’s always a weak point people miss out on. Add both the gaskets and the door bottom to prevent sound from leaking"
