Sound insulation is an important detail to creating a comfortable environment in homes. A must for bathrooms, laundry and mechanical rooms and a bonus at bedrooms.

Low cost, high impact. @ROCKWOOLNorthAmerica - Jak na to + styl
I insulate interior wall cavities every time I have the opportunity. Remodeled a bathroom and rockwooled walls and ceiling. Remodeled a bedroom and rockwooled the walls. It makes a huge difference in not only sound but the temperature is also more stable.
I did the same .made 2 bedrooms one kitchen and renovating a bathroom and insulated all the walls.
Ive pretty much started just installing insulation in every wall
How good is this for sound proofing compared to regular insulation?
Almost the same, 10-15 percent better
Any insulation product 20% the price of rockwool will give 80-90% the performance of rockwool as a cavity filler.
@@simpletonballsack Which material offers the best balance between price and performance, in your opinion?
@@rachel705 Any glass or polyester batt with density at least 12kg/m3.
Can I ask why you have a guy in full tyvek and a respirator just to install rock wool? I thought it was supposed to be safe.
It looks like they’re spraying the roof
It’s non toxic, that doesn’t mean it’s safe. You Rock the bear suit so you don’t get really really itchy and the respirator so you don’t end up with a smokers cough of sorts.
It’s very costly
Great idea to insulate internal walls for noise but Rockwool is way overpriced for regular thermal/acoustic use. Its main benefit is in high temperature applications.
We feel differently
@@NSBuilders I can tell you do but despite this purposefully silly profile name, I've been running my acoustic consultancy for 26 years and have reviewed and compared NATA laboratory test results for just about every product on the shelves. Your feelings are wrong but I wish I had a dollar for every builder I've encountered who feels the same!
What would you use in its place?
@@Daryl... Just grab any glass/mineral/polyester fibre insulation that fills the cavity and you'll get within 2 dB of the acoustic performance of "rolls royce" rockwool (Theoretical maximum increase in sound transmission loss from cavity insulation is 6 dB). A sound level difference of 2 dB is the limit of detectability but people selling acoustic products will try to convince you that their 2 dB improvement is great. I've just laid glass fibre insulation in the roof of a 100 year old house I bought, just for thermal, and I'd highly recommend polyester insulation for ease of handling. Once your shirt if full of fibreglass, it can't be removed so just throw it out ... after the itching stops!
@@simpletonballsack recently redone our hall ceiling with acoustic Rockwool, it works well. I think the biggest difference came from the acoustic plasterboard though.
Will say I didn't notice any significant difference in sound travel between the "acoustic batts" and the standard earthwool roll.
I'll take a look into that other insulation, need to build an office room and although the acoustic stuff isn't super expensive, it's also not cheap
Why are they wearing full hazmat suits? Gloves and a mask is the recommendation. And even that might be a little much
Keeps them clean.
Rockwool is a whole different animal. I can install regular insul all day in shorts and a short sleeve without a mask or even gloves. 5 minutes with rockwool and I feel like one big mosquito bite.
@@Tool_Addicted_Carpenter rockwool as cavity insulation only gives an imperceptible 1-2 dB improvement over basic polyester batts.
Just stop
