Soundproofing Insulation - Know THIS Before You Soundproof!

Here are the facts about the different types of insulations you can place between your walls for better soundproofing. I will talk about the insulation that is made to soundproof a wall.

These insulations range from spray foam insulation to batt insulation but which one is best when wanting to soundproof a room in your home? That is what I will answer in this soundproofing insulation video.

I just discovered your channel and I just wanna say TYSM! I’m on a mission to soundproof my room and your videos are amazing!!

I use old mattress box springs, filled with Rockwool, and they work AMAZINGLY. A square room with artificial Pergo floor, and all smooth walls. I use a full size and queen, then cover them in black fitted sheets and they look sleek. Very helpful for people who can’t modify the existing construction. Definitely not sound proof, but a HUGE help, especially when used in combo with ATS panels.

I installed rockwool, and it never fails. Not only is it super sound deadening, it’s fire resistant. We redid a barn add a guest house on a property in Napa with Rockwool and when the fires went through the house burn down, but the barn and guesthouse burned so slowly that we were able to save them. How’s that for a testimonial? Here’s the downside. The soundproofing was so stunning and solid in the barn and the guest house, that you can’t hear any nature or people talking, approaching, or whatever. It’s so quiet that it kind of made my ears ring from the quiet. What that means is that you couldn’t hear anybody walking towards you which means it scared the hell out of you when they open the door. I’ve used rcokwool the city, and it works as good as it can. The only better soundproofing I have experienced is the click clips that you hang sheet rock from, and even though they work better, I think Rockwool sufficient. Just know that if you’re in a quiet area to begin with, you’re turning whatever room you’re insulating into an isolation tank.

One final note about foam. I suppose if you’re building a new house, foam is an option. If you use foam on a really old house, like a Victorian, the foam will eventually absorb moisture, and it will rot. There is no way to make a Victorian, Edwardian, or craftsman style house perfectly waterproof. They were designed and built to breathe. If you put Rockwool in the walls, any water absorption will be easily evaporated. With foam, the water won’t evaporate and you’ll start having a mold problem. For that reason, I never ever use foam. You may not notice this problem for the first 15, 20, 25 years. But the foam will eventually absorb water and you’ll have a huge restoration issue on your hands.

What’s best for a townhouse with NO insulation and neighbors on both sides with hard wood floors upstairs & down. I’m going CRAZY from all the noise & i can’t move for a year

[giuseppinasolinas]

I have a 12cm stud wall separating the master bedroom with the small bedroom. You can hear everything, impossible to have any privacy.

After much research I have decided to use Rockwool batts in between the studs and Knauf 1.25cm acoustic plasterboards on each side of the wall.

Would you say this is the best I can do without losing space?

Any recommendations on type of drywall? I'm hearing impaired and we are looking at sounding proofing home. Based on your video, I think I'm going to look at Rockwool. We currently have blown-in and it's terrible. Had an appt for open cell today but, they couldn't do it due to our blown-in insulation. My goal is to have a nice quiet space to minimize sound disturbances as I wear hearing aids. Any recommendations would be great.

[mirlamurillo]

Yes, great info and very well organized! Thanks.

Thank you for this video. When I owned a house (built in 1794) I did a double floor 30cm above the first on the top floor in the attic on the 4th floor, to fill it out with cellulose, it did a very good job.
Now that the house is lost and I'm in a shitty building with a brainless neighbor and their pest little girl stumping every chance she has, shooting at her mother, throwing objects around, etc ..
Last time I went to their door, the mother told me she couldn't care less (to stay polite here)
The landlord doesn't care either.
What can I do to soundproof *their* sound on *my* side, without ruining my wallet nor my small space ?
It looks like it was a single apartment divided in two, with a long wall all the way from the front door to the back room, so we have the same floor and the separation wall is like 2cm thick ?
My side of the corridor is 37'' wide, so obviously can't go with a 30cm thick not even a 10cm thick, I'm more thinking about 2-5cm thick material ... and for the floor, to limit the bang-bang-bang echo of the little chimpanzee guenon ... I have no idea, a floor mattress band on the wall side ?

Hi, we have upstairs neighbors that can get pretty loud at weird times of the night we live in a old apartment with wood floors and carpet but very little padding. Was thinking about installing rockwool safe and sound in between the floors over our bedroom. What are your thoughts?

[ebbertgepner]

Have you checked out r-30 denim insulation batts? I wanted to ask if you've evaluated the this and it's soundproofing qualities vs. the options you provided in this video.

[jonkoutylee]

Thanks for your video! But blow-in and spray foam are the only feasible way to do insulation into an existing wall without reinstall the wall...

[BlackFlashDrive]

Hey Soundproof. Great content-- keep it up!

I have a question. If you were to rank the following based on effectiveness, what would be the order?

Installing:
3 coats of soundproofing paint
A sound absorbing panel
A mass loaded vinyl
A resilient channel with a dry wall
A dry wall

I need to soundproof a ceiling between second and first floor what will be my best options there is sheet rock on the ceiling right now

[jameslewis]

Just saw your video, am familiar with the three most commonly used - foam, finder glass and rock wool. And of course every contractor has their opinion. So I’m building out basement below main floor house. Floor joists are 2x10, my plan is to use r30 fiber, resilient channel and 2 layers drywall with acoustic caulk between. Any better option you might recommend?

[vivalaleta]

What about bat insulation with aerogel covering the studs? Expensive but the price is coming down for the stuff.

[DavidHagrid]

Does faced or unfaced fiberglass work better for sound reduction?

[samcho]

Which is a better option for soundproof our shared walls on townhouse? Blow in insulation or resilient channel with 5/8inch quiet rock

[MR-mlpo]

Would you say that having insulation in the walls can help to insulate from upstairs impact noises?

[robertdatson]

Pink batts an 2 sheets of acoustic gyprock ..👌

[medmuckersmedia]

What about cork boards for sound deadening?
