Hey everyone! I'm working on soundproofing my bedroom because my downstairs neighbors are quite noisy. The walls are made of a lightweight material called 'light-crete' with just a thin plaster layer, so I suspect that's where a lot of the noise comes from. My room is pretty small (about 3.5m by 3.75m), and I'm planning to add a single layer of 5/8" drywall to help combat the noise. I have some Green Glue ready to go, but I'm unsure if I should use it between the light-crete and the drywall or just attach them directly to save the Green Glue for later use in my living room, which needs soundproofing too but isn't as cramped. I know Green Glue is often tested with double drywall configurations, but since it's a damping compound, I'm curious if it would still be effective in this single layer setup. Given that my walls seem hollow and vibrate with sound, I'm hoping using Green Glue would help. I'm looking for opinions or experiences from anyone who's tried this or has advice about which method might be more effective!

Using Green Glue could definitely help reduce some sound transmission, especially since it can dampen vibrations. Just make sure the drywall doesn’t touch the floor directly. That’s usually a key spot for sound leakage. Leave a gap, use foam rod, and make sure to caulk everything to seal it well. It can’t hurt to use the Green Glue, but remember that the goal is to decouple the drywall as much as you can, so keep that in mind when you're installing!
I totally understand your dilemma! If you’re leaning towards using the Green Glue now, you might save yourself some hassle down the line. Should the first layer not work out, you're right that you’d still need a second drywall layer, but at least using the Green Glue might give you some peace of mind that you're making the best choice with what you've got. Plus, better safe than sorry when it comes to noise, right?
Exactly! It's all about weighing your options. Using it now might seem risky financially, but it could save you from spending more in the long run if you need to fix the noise issue later.
Good point! It sounds like you're already on top of sealing everything up. Just be sure to keep that gap to limit contact points. Sounds like you're going to do a great job!
