Pink Fibreglass Insulation For Soundproofing or

Thanks so much for this info! Very helpful!

Sounds very truthful. You should create a box with different material and do a test with a microphone built into your phone. Use different insulations and sound editing material as another test

I saw a guy who stuffs wool material in hard to reach places in cars.

You need to give some actual hard data. You are saying the stc is higher, but somehow it doesn't matter? I don't know if you notice, but you are talking a lot, but not actually saying anything, especially not about practical soundproofing advice. Please don't advertise yourself as such.

Fire resistance, not a thing, really? I think the people in Grenfell would have been grateful to have been sponsored by Rockwool.

Thanks and I agree. My question is have you looked at the pink brands that now have 'sound reducing' varieties? They split the difference in cost between rockwool and the regular pink stuff. I wonder if that is an even more marginal difference for 20% extra or whatever (ie. not worth it). I will say though that some people claim rockwool helps absorb lower frequency sounds quit a bit better than the pink stuff, which the STC rating doesn't cover. I know flanking paths and other things make a bigger difference, but I wonder how much better it performs in these situations (If a neighbour on a party wall attaches the soundbar to the wall and the bass that comes with it)?

Thank you for the big-picture advice. Instead of using Rockwool and 1 layer of drywall, spend less and use pink + 2 layers of drywall and get better overall effectiveness. If your budget allows, sure, use Rockwool instead of pink, but 2 layers of drywall does more than pink vs wool with 1 layer. Pink is half the price per square foot vs Rockwool.

I did try installing pink insulation in my ceiling to reduce sound transmission. I've put 2x R12 in my ceiling and saw next to no difference between with and without. Right now, i'm redoing with rockwould safe and sound to see the difference. In the end, you want mass and rockwoll really add way more mass then pink insulation. I'm curious to see the difference when I finished, specially for bass.

Hi. Can I get your thoughts please on a different product. Deciboard. Any good or overpriced and can be done cheaper with drywall and M20 or MLV? Thank you

On my bedroom addition I put the pink insulation between that and kitchen. Also have solid pine six panel door. Worked well. Can’t hear much through that.

Thanks for this.

One other suggestion, not sure if it has been covered, is to use a 2x6 plate on the bottom with 2x4 studs altenating sides.

This way, the drywall in room 1 is not connected to the drywall in room 2 further breaking that vibration medium for sound.

mind blowing!

Is it dangerous to having a pink fiberglass exposed ceiling in utility room? If so how do you protect yourself. Should you encapsulate or replace? Who would do that work? Thank you for your expertise!

Solid advice / info, thank you 🙏🏻

inside a wall the difference between R19 and rockwool is unnoticeable. Rock wool is slightly better for building corner bass traps, but if you just compress more R19 into the same space, again, works the same. I use Pink stuff for everything, because availability and cost to sq foot is just better. I just use more of it.

Can this pink fibreglass wool be inserted in a light fixture hole in the ceiling to block impact noise from neighbour above in an apartment?

“The Rockwool will not save you or your house” 😂

Still waiting for someone to build a small fiberglass vs rockwool box and have a microphone inside with quality speaker outside playing numerous normal exterior sounds ( car engine, car door, garage door, large truck sounds, dogs barking, airplanes, lawn mowers, leaf blowers) Recording the db levels. Not perfect since Windows and Doors are a factor but would have an idea vs Speculation

Fire proof is for inside the wall fires and not what you and your friend is talking about. Of course if the fire is in the room, you are screwed. But if the fire starts inside the wall, you are definitely better situation with Rockwool.

The pink fiberglass in your video has a rating of 35 and Rock wool 45. A difference of 10 is HUGE when it comes to soundproofing!

Does this help with sound reverb

I love common sense videos. Thank you

Sound is just air pressure differences. You want to make the wall airtight, and also solid to prevent resonance.
