7 reasons I went with Rockwool. #1 today's video was sponsored by rockwool. 🤣
He forgot to mention that Rockwool in Europe is not allowed indoors because it has been linked to lung cancer.
This channel would be so much more valuable if Matt would take more seriously conflicts of interest. He could get this video sponsored by a roof shingle manufacturer or something. I have to be skeptical of nearly everything he says on this channel, which now that I mention it, makes me wonder why I sub at all.
@@kostasg7109 Any link to this and what do you mean "not allowed indoors", like not covered with drywall or something similar? Looking at the EURIMA (European Insulation Manufacturers Association) they have nothing negative to say about mineral wool insulation - "Its exceptional thermal properties contribute hugely to European efforts to save energy and combat climate change. " www.eurima.org/about-mineral-wool.html
@@kostasg7109 i have no idea where you got that information but that is definitely not true.
@@kostasg7109 Lie!
at the start of the video, you could already tell how well insulated his house is from the audio in the video. this is the best sound quality I've heard from inside an incomplete house
I agree, it is incredible.
Never noticed that. Thanks!!!
Rockwool is awesome for that! We cannot tell that it is raining or lightning outside. We can't hear loud cars either. We literally hear nothing unless we open our windows. The only thing we can hear is rain on the metal roof if we go up into the attic. Otherwise we wouldn't even hear that!
22 years ago I chose Rockwool for my house and have no regrets! Its awesome stuff!
Hey, but does rock wall keep the summer heat out?
@@Righteous_hill_bandogs rock wall greatly reduces the transmission of heat and cold, however if the inside is already hot it will keep that temperature steady, unless you have a cooling source.
I installed RockWool Safe-n-Sound in the partition walls when I remodeled my basement in 2012. I was adding a bedroom for my father-in-law and he's a super light sleeper - very sensitive to all sounds. His room is now the only place in the house where he gets decent sleep. The stuff works, and the added benefit of fire resistance is great for some extra peace of mind. Glad to see some videos to expand the knowledge of these products.
Former insulator here. It is good stuff. We only installed it to meet certain fire codes, usually in commercial buildings. I would say around 90 percent of all homes being built still use fiberglass batts in the walls and blown in the attic though, they don't want to pay for the extra cost up front despite the obvious benefits.
Obvious benefits would be to live underground. Natural geothermal energy efficiency and no UV radiation 🤣🤣
If I start a home building company I’d use rock wool on every exterior wall and roof area.
@@MrMasterMarksman Radeon could be an issue, depending on the area you build your cave.
When renovating our 1800s era home I used the safe and sound by Rockwool for the stairwell in addition to fire rated drywall as it being our only means of escape from the second floor in the event of a fire. I figured it was pretty cheap insurance as an extra layer! I also appreciated the rigidity of the product when installing in the basement crawlspace under the foyer.
As a commercial construction worker I'm extremely familiar with rockwool. It's an excellent product not nearly as dangerous as something either fiberglass or cotton-based or paper based. I constantly had engineers in Florida asking repetitively for it. And I was happy when they did
I disagree wholeheartedly rockwool is way worse for health.
@@rekostarr7149 because?
@@tcoradeschi particles get in the eyes (even with glasses) and stay in the air it's insane (so once you take off your mask you're gonna start feeling the impact (maybe not immediately but pretty soon). the thing doesn't stay together on a microscopic level!
@@tcoradeschi fiberglass isn't dangerous at all in comparison there's much less breathing hazard and half the price!
@@rekostarr7149 well .fibreglass isn't bad for you anymore but neither is rockwool. Fibreglass is super itchy to me rockwool isn't. Both products only produce nuisance dust. An fyi from a ten year insulator and now ten year safety specialist.
I've got rockwool insulation in my garage as of a week ago and you aren't kidding one bit Matt, the sound dampening out there almost keeps up with the 1 foot thick SIPs in my house...its just ridiculous! You do a bang up job pushing construction tech and info out to the masses, so cheers to that bud! Best of luck with with the rest of the house and thanks for taking us along for the ride too.
Just got finished putting the R15 RW batts in my shop building, and my wife said she cant even hear my planer or tablesaw outside. It was also incredibly easy to install. I used an electric bread knife to make all my cuts, which worked way better than I expected.
I like the comparison of different Rockwool products and it is the tip of the iceberg. Their marketing tends to say, "use this here" but not always explain why. CavityRock vs. ComfortBatt? TopRock vs. Rockboard? Roxul Safe vs. CurtainRock? What challenge were the engineers solving when they developed each product, and what changes did they make to solve it? Hoping we can take advantage of your inside access to Rockwool and get some of these nitty gritty details! Thank you for all the content
I would also like to know.
GREAT info! Loved the real-world demo with the shop vac at the end. I’m envisioning having guests over and not even disturbing a sleeping baby. Kudos, great work as always!
I remember using this with a Gyproc system, double board in Soundbloc and acoustic sealant. It works and very easy to install.
I used rockwool when I was building out my office. Ripped out a bunch of walls and had to replace the pink fiberglass batts. The rockwool is substantially less itchy than the fiberglass, at least in my experience. The sound deadening seems much better too.
Sound dampening is a must
I find rockwool worse than normal fiberglass
@@CrzBonKerz21 Same and I think most people get placebo effect from it.. Independent studies show that Fiberglass and Rockwool have the same STC rating which in a typical wall is around 1 STC (which is not noticeable to the human ear)..
@@FJB2020 All depends on density of product ranging from glass fiber, polyester and mineral. All have different purposes ie, thermal rated, acoustic rated or FRR etc - generally speaking mineral fiber (rockwool) is a much denser product compared to your conventional fiberglass or polyester. Price range of material goes from fiberglass > polyester > mineral wool. You get what you pay for.
I found rockwool is much less itchy that glass wool. It also has no binders so it is fireproof.
It can also be spray filled into the cavities. Foil faced plasterboard gives a more than good enough vapour barrier.
The reason was given at 0:30
Yeah, but nonetheless RockWool is the superior product.
😂 you aren't wrong
@@Recovering_Californian It may be a good product, but we got a sales pitch and not an unbiased opinion.
Yup lol
@@Ethan7s Do you find the information he provided misleading or untruthful. If you do, what batt insulation would you recommend instead?
Love your videos. Covers all aspects, best materials of the how's and why's. I've been passing on your channel to others within my Discord for my friends that are doing major remodeling of their old houses. Thank you. Even for the DIYer, contractors coming in have given compliments of the work within my house for areas I can't cover.
Also thank you for all the links attached to your videos, it has made hunting down the materials for certain areas , our stores don't carry to order it in.
After watching many videos Rockwool is the only insulation I will ever use. I've been renovating a mobile home on a 2nd property and I've used it exclusively. It's worth the $. Rodent and insect proof. Fire proof. Water proof. Sound deadening. I love this stuff. I have one mini-split in that home and it's real cheap to run thanks to proper insulation. Best tip: use a bread knife! So easy! Attach it to a magnetic measuring tape for precise cuts.
Civil Engineering from Denmark here. If you didn’t know Rockwool is a Danish company. Doing my work and studies, Rockwool is all we talk about.
As a science nerd I aspire to work for Rockwool, not just because they make nice insulation but also because they might have the best R&D department in the country. Meaning, they have so many nice products.
Good luck with the build.
Doing a remodel now and all the garbage out and only Rockwool in. Retired electrician, never recommended anything but Rockwool.
@@JT-pc5kp the short answer is rocks.
This video explains it really well.

Hello from Sweden. We have a mineral wool insulation called paroc here. But I guess it's the same just different brand names
@@2strokepower803 it looks to be the same yes.
Cool job!
Just did my entire house in rockwool. I live in the High Desert of Southern California, where it's 115° in the Summer and snows in the winter. Its like living in a ice chest. The insulation properties and sound deadening is insane. Definitely worth the extra money. Probably the best thing I did in my remodel especially considering the price of utilities nowadays.
How thick are your walls, please ?
The Best Tag Line on YT IMHO. Short, Simple and Catchy.
Your videos are so good and accurate and precise, I appreciate it from someone that builds and invents this is great information. Great job well done rockwool is amazing!
I used Rockwool when I built an office and it made a huge difference in noise reduction. This stuff is amazing and easy to install even a DIY.
Yup! That’s it I had it!! I’m ripping my walls out and replacing my standard pink installation with rock wool🤣. Been debating and watching videos on here for a few weeks now and this video persuaded me. Thank you for educating us viewers! I wanna turn my bedroom into half studio and half bedroom and I think imma give that Rock wool a try. Oh ! And I’ll probably incorporate it in any future builds like you have your whole entire house.
Thank you!
Rockwool is one of my top building material picks because the batt density is so consistent and they cut like cake. As you can see, the fit and finish of the installed product is excellent. Worth the extra cost!
I do like it. I was in commercial construction for many years. Many projects were speced out Rockwool way back then. I am thinking about building a cabin and think I will use this product. Thanks Matt.
You've had me sold on Rockwool even though my contractor is trying to change my mind.
Reason why your contractor is trying to changing your mind, more then likely they’re getting some kind of incentive from manufacturer/supplier or both. More often that’s not passed onto you as the owner.
@@ABC-oo4vm yes because this video being sponsored by rockwool has no bearing on his opinion i am sure.
Just tell them you know Matt Risinger, and ask for the sponsorship discount ;)
@@CookieManCookies when hogs grow wings, just then it still a maybe.
he even says they allowed him the freedom to use other types of insulation thats why 5% of his house is other insulation dont use rockwool the contractor is right but dont use what the contractor wants do your on reserch this guy says hes sponsor by rockwool and been sponsor so if he shows anyone else he brakes his contract
This channel has so much useful information per minute... it is hard to compare. Great source of into!
Thanks!!!

I am so stoked for your house. The sound attenuation by itself has me mesmerized.
I’m feeling really blessed. It’s an amazing home
I'm putting in Rock wool in my new build, thanks to you, and i have done it bare handed and short sleeves and have never had any itchiness.
i'm installing rockwool in my house as well but my wife is fighting me every step of the way just because of the price..I just know this will be the best choice for sound insulation throughout the house.
thanks for this video and keep up the good work :-)
When I did the siding replacement on my house, I used Rockwool and was very pleased with the results. My house was a 1950s with no standard spacing in the studs, no insulation, no sheathing, and no vapor barrier. Previous owners spent a lot of time making the inside look nice and I didn't want to redo all the drywall to insulate, so I redid the siding ( it was masonite) and went with smooth Hardie plank.
How much did that run ya?
@@Jekyll_Island_Creatures I don't even remember now. It was a while ago.
What is the change in your heating bill? And house drafts? This is my plan for the spring on my 1960s house.
@@angellas.1314 I really didn't get the chance to really find out. Shortly after doing the work, I took a job in a different city and had to move.
How did you put vapor barrier? I have 1900 house was planing to do the same but not sure how to add vapor barriers
When I get around to building my own house, I will have so many great ideas from this channel. Thanks!
Used Rockwood on our covid home Reno and it has been great and the quietness before putting up the drywall was unbelievable, just like the mike test here.
Those studs looks so nice...almost a shame to drywall over.
I notice the same too!
LSL studs are cheaper than dimensional lumber in Northern Colorado. I will never go back... they are a bit harder to work with but they are perfectly straight.
I'm also sure the installers loved to install rockwool in your house, especially safe and sound, they made a great paycheck 😀👍. Water permeability is also a big key for rockwool vs fiberglass.
Matt I’m so thankful for all that you have taught me throughout your videos. Very cool “nerdy” information. Wish I would have known these things 10 years ago.
I am however going to have to disagree about using fibrous insulation. Closed cell foam is the only insulation, in my opinion, that should be used.
Have have been learning from spray Jones about the “nerdy” information of insulation. So much so that I feel fibrous insulation should not even be sold.
Using the safe and sound for your interior walls I feel is a great idea. Grace and peace slick.
I used Rockwool on a 150 year old house conversion here in the UK. North facing walls, framed and Rockwool stuffed, between framework also framework between rooms, all floors and ceilng joists similar. over three floors. Roof space and eaves filled. Cost a bit but what a result. Low heating costs compared with before, sound control absolute winner. The other advantage which you could have shown with a Blowtorch. Get a slab and heat up until red and feel the back of the block. Hardly any heat transfer front to back. Great as a plumbers torch barrier when soldering copper pipes.
Thank you so very much for all the knowledge you have passed on. I just want to say how much I like the feeling of being in an area that has been insulated fully with rock wool. There is just something about it that I find comforting, don't you?
Appearances of commercial bias aside, Rockwool is good stuff. Used it recently in a complete home renovation. Installs nicely....way better than fiberglass. More effective as well. Highly recommended.
Thank you for making these videos. I'd like to buy a house I'm the next 5 years or so, and this channel is immensely helpful.
Big fan of Rockwool, use it on every project I can. My local lumber yard said they are 150 days out on rockwool orders currently.
We had loose rockwool insulation in the ceiling of the house I grew up in, and it was definitely superior to anything else IMO. And if I live long enough to actually have a desire to remodel the house I live in, rockwool would be my first choice bar none. Thank you for extolling rockwool's many virtues.
Your opinion is correct i always felt the itch with JOHNS MANVILLE and not Rockwool.....
"we're in the insulation phase..." Your entire project is an insulation phase 😂
Its important.
Your water doesnt make you comfortable. Its nice to come home to a cozzy house.
Great information, and you actually answered a question of mine regarding insulation in the interior walls. Now I have a home built about the 1940's in Deep South Texas so your information has been a great guidance.Your videos have been a tremendous help, especially with much of the work being DIY since I don't have the finances to pay contractors and their workers. But in the same note the savings in labor is allowing me to install better quality material. Thank you for sharing your experience and trade knowledge with others to better understand build, but also provide direction and confidence in DIY projects, thank you.
You will get the same results using Fiberglass.. Understand that matt is basically a sales man for whatever product he is getting for free.. (Do not trust what he says)
@@FJB2020 Products he shills for can still be quality products for people willing to pay premiums.
@@LackeysLack True, but I can no longer trust his judgment if he only says 'This is the one to buy, trust me, oh and this video sponsored by the same product I am telling you to get'...
Having worked in residential, commercial, and industrial construction over 26 years, I paid attention to industry standards. I did my homework, and I learned about what products are best for fire rating, sound dampening, and R-value. This insulation is the only insulation I would use when renovating my own house. There is no way I would ever want foam panel insulation or spray foam anywhere near my project. I've been watching videos on how to install this insulation on the exterior of a house, and I found the videos interesting. Thank you for the video, I always appreciate other perspectives as it helps me to learn something I might have missed on my own; or it affirms my own thoughts about certain products. Have a great rest of your day.
I know Rockwool is a sponsor so I apologize but Owens Thermafiber offers all the same benefits but uses no formaldehyde binder thus healthier option.
I’ve used Rockwool for years, actually when it was called Roxul. Didn’t switch to Thermafiber until the last 18 months when a client specified Thermafiber due to the formaldehyde free content. It’s typically slightly cheaper too. Only issue we’ve had is availability can be scarce.

I have Cancer and am fighting for my life. I would be very concerned if the product is carcinogenic. I wouldn't want my boys or future generations to go through what I am going through.
My woodshop is right next to an apartment building. I insulated it with rockwool and did the walls in MgO board. My neighbor who lives in the apartment building just asked me what I did in woodshop . . . He had no idea that it was a woodshop. This stuff is amazing at sound insulation, especially if you pair it with MgO/plaster instead of sheetrock.
What's MgO plaster?
I love this stuff. I use it in recording rooms and to fill acoustic panels and it’s superb.
RW is going into my house when it gets built at the ranch. Already decided that from a previous video you did on the fire resistance but the sound deadening is the bomb too.
Check out the "Bahco PC-22-INS Insulation Saw
", we used Rockwool in our garage and in many other areas we have remodeled. That saw makes it super easy to cut and stays sharp. Been through hundreds of pieces and cuts like butter still.
I use a $9 harbor freight 10 In. Japanese Style saw.. works great.
Dollar store serrated kitchen knife works beautifully.
I have a 120 year old Victorian house. I used Rockwool. Fire mitigation is a real thing in these old girls. Soundproofing and ease-of-use, especially with an electric fillet knife. Cost kind of sucks, but buy once - cry once.
awesome idea for cutting!!!
Buy once cry twice and you'll usually come out enjoying your purchases. Research is key lol
Great video. The sound dampening in Rockwool is excellent. I can't believe anyone uses fiberglass batts anymore when there are better products that not only absorb more noise, but are also fire retardant.
My parents house is also nearly 100% Rockwool and that was 24 years ago in Canada. I have done a couple remodels to my house and where possible I pulled out the fiberglass and replaced with Rockwool. I am a 100% supporter of Rockwool
Best insulation for old houses. My house is 224 years old and use rockwool on my projects. Fireproof, doesn't hold moisture, rodents don't like it. My walls don't have studs, planks placed at random, nice to stuff rockwool in. Love the stuff...
I love rockwool, it’s a superior product for sure
Never heard of quiet rock before, looked it up and love it as far as the science goes, likely to use in my basment remodel
dude I love your videos you’re so informative and your presentation is perfect. I’m sold on the rockwool for the insulation choice of my van that I just purchased.
Hey Matt,
Something I've wondered about is using conduit for running wires what is the negatives on doing this? I figured it might be really helpful to make things future friendly for upgrades.
please do the sound test again after drywall, since the exposed rockwool will dampen sound much more when exposed
I don't think that's true but I'd certainly be interested in seeing. I don't see how anyone could make the argument that sound would travel through two layers of drywall plus rockwool easier than only rock wool. But I could be wrong. Drywall itself is a pretty decent sound barrier (not as much as RW) and esp if you get a larger size (5/8 not 1/2 inch).
P.S. Perhaps sounds WITHIN the room would sound a little louder with drywall since the sound would bounce off the drywall easier than the RW but for sounds outside the room..... yeah I think the DW would only enhance the sound deadening. And I think most people are worried about exterior noise (e.g. TV in another room, loud kids, power tools, etc.)
@@user-nh3gu1ge3d sound bounces off and travels around drywall so with the doors open the sound would travel farther than no drywall. its why low sound rooms have the triangle foam exposed as opposed to behind a flat wall
I've used this in three studios that I've built so far. They're so quiet that I can hear my ears ringing. The drywall does bounce some sound off. But the sound stays within that room and doesn't really travel through the walls and or ceiling.
Of course the walls will echo with drywall installed but you shouldn't hear much of what's on the other side of the rockwool.
Thank you for the great video. I like that you were upfront about the sponsorship, but it felt that you were still very objective in your assessment.
Very informative. Seems great as you stated for a video audio studio or any place that requires the deadening of sound. Rock wool look like a great alternative to sound foam or new see together.
Hey Matt could you talk about how you being sponsored by Rockwool doesn’t make you biased about any product!?
I’m getting mixed reviews on multiple youtube builders/contractors about many products!
Even if he is sponsord by Rockwell I doubt he would have his whole house covered in it if it was rubbish.
Please redo the shop vac test once finished, I wonder if drywall will make it worse... (Doors open and doors closed)
It's more about keeping the noise in 1 room and not transferring to another. It will still travel. The drywall will cause it to bounce more so it will carry better but won't transfer through the wall.
Just like an empty room and one full of stuff. It will be worse after sheetrock, and better once everything can deaden the sound.
Drywall makes it worse for the room you are in but better for being in the room next door. If you want to reduce the sound transmission out of the room you are in 5/8" drywall can improve the situation. Also can to RC clips, another layer of drywall, acoustic caulk, separate the framing.
@@davidmorrow4195 All great tips, thank you. Thoughts on RC clips vs. horizontal furring strips to minimize sound bridging (I.e. cost, labor, efficacy, etc.)? I've used horizontal furring strips combined with Safe 'n Sound and Homasote to great effectiveness with a laundry closet in a master suite. Thanks!
@@drewt3210 I think RC channels work better than furring strips but only used the channels, not the additional clips (maybe I should in the future?). I used them in the ceiling of a room. I did a lot of research on sound insulation. First thing to do is to make sure it is air tight between rooms (electrical boxes, caulking under or above framing). Safe n Sound works better for high frequency sound, low frequency sound (bass, walking on ceiling) travels through things so either additional mass like 5/8" drywall (cheap option but heavy), 2 sheets or decoupling works best. I used the mass vinyl mat (like Homasote) on the house next door to ours that we purchased as the house is 8' away. Seems to be a great solution but heavy and expensive. Putting up Resilient Channel (RC) is basically the same work as furring strips (maybe slightly more difficult to cut because sheet metal?) but does a better job as sound has to come through the framing, then can't get to drywall because drywall screws are only in channel, channel is mostly decoupled between framing and drywall. I also looked into Green Glue Noise Canceling caulk with goes between two sheets of drywall and will likely use this on next project which will be our living room ceiling. Seems simpler than RC or furring strips and is supposed to stop bridging. Can put up sheets of drywall very quickly, then mud and tape of 1st sheet is only to cover gaps (offsetting gaps on 2nd sheet). I hate sound from outside or between rooms and really like it to be quite.
Wow. That sound reduction is amazing.
I've been installing Rockwool on my projects over the last few years. I have to say it is a superior product.
Great video - thank you! I have some questions about using RockWool for exterior insulation. I am leery of using ridged foam for exterior insulation in fire country and have thought RockWool's ComfortBoard 80 and RockWool Roofing Insulation would be better options in areas prone to fire. I would love to hear you discuss this issue and the pros and cons to the options. - Thanks!
Matt, I used this in a studio/tool shed new construction project in my back yard. The easy cutting enables you to fill the entire cavity, no voids like most insulation products. Spray foam has the problem of not being installed correctly unless the equipment is working perfectly, the installer knows what he is doing, and does it. Rockwool is DIY friendly. It should be the only insulation sold for wall and ceiling fill. It out performs all brands, it is expensive, hard to find, worth the effort, worth the additional cost, much more quiet, really gives you a high performance product. This is no place to economize the build. Putting this behind your wall covering will reward you as long as you live in your home. I would not have used it had I not watched Matt's channel, so glad I learned of it. It is the only insulation I will use in the future.
Thank you for your videos! This helps me a lot as an architecture student
You convinced me to use it. Especially the sound bats between the rooms.
If I ever have the money to build a custom home I’m definitely using rockwool.
I used Roxul sound & safe too, at a small fortune. It would be interesting to see a demo on the 2xs catching fire, and how much if any the rockwool helps as a block to stop spreading to the next stud bay
If you really want to see it, there are other video's (not by Matt) that show side by side, Fiberglass, Rock Wool, open cell foam, and closed cell foam. While the foams will give better temperature insulation, they burn like crazy. Closed cell foam, at least and most likely all of the foam products, will also give off some really nasty chemicals which will dramatically reduce the likelihood of escaping a fire. As a former firefighter, even I was amazed at how fast they burned. Meanwhile, the fiberglass and Rock Wool did not burn. For the fiberglass, the paper backing burned, but the fiberglass, being glass won't burn unless you get up to the glass melting temperature. If you get close to the glass melting temperature, it may get a little gooey. As an example, in today's house fires, fire fighters are seeing temperatures starting around 400 degrees up to 1500 degrees. At a house fire I talked to fire fighters about, their FLIR camera read 742 degrees looking down the hall towards a group of bedrooms that were well involved. The Rock Wool did not ignite at all. You could barely tell where the torch was. Only a small amount of char was seen between the shelves with the Fiberglass and Rock Wool, where the Foams allowed almost complete burn up of the shelves. The example structure was an inexpensive wooden bookshelf as the tester discovered building a new wall as he had planned, was very expensive.
I grew up in Austin, it’s a beautiful city. If I still lived there I would hire you for sure. I use rock wool to grow plants in my hydro system.
Will be using Rockwool and QR “dyrwall” for a new master bedroom & bathroom remodel coming up.
Like the products and work well, along with ease of use from the products themselves 👍🏻
Matt: "You should wear long sleeves, gloves and a dust mask."
Insert clip of installer, wearing a tank top, no gloves, and a backwards baseball hat!
I’ll be using the same on my house, I build loft conversions in the U.K. we are always fitting PIR boards, don’t like anything about them, cutting, installing, also, they let off a rancid smoke when we tested in a naked flame, no matter what you do with PIR to protect yourself, the dust gets everywhere, as it’s static like, even with the festool cutting tool and extractor, Rockwool is definitely better for sound proofing too.
Hi, are we able to use it in uk ?
Great video - super informative/ helpful. Also - that drone shot of your black metal roof..? Wow - B-E-A- YOOtiful!!
Love using Rockwool. Thanks for the info.
I did my house in rockwool the one thing to keep in mind that dramatic sound attenuation will be reduced once sheetrock is up
Just cover your walls in velvet
Hi Matt, as a drywaller from Australia I just wanted to note how important it is that the insulation not protrude past the stud wall line, it seems like it will compress when you press on it, but over a large area it transmits a HUGE amount of force on your drywall.
I for one appreciate your info. Thank you
I used Rock Wool throughout the rebuild of the downstairs 950 sq ft apartment in our 50's built 2x6 frame house. It was back to foundation/studs. 2x6 Rockwool in studs above foundation to second floor. New interior 2x4 framing for interior walls with 2 inch offset from foundation and exterior 2x6 walls. 2x4 apartment walls facing exterior Rockwool insulated with 2x4 exterior, all interior facing walls insulated with 2x4 safe and sound, 1st to second floor beams filled two layers of safe and sound along with rezbar and 5/8 drywall. All gap areas fire stopped including wall transitions and fireplace areas. Finished with poly and acoustic sealant vapor seal.... my wife and I lived in this space for 8 months after the build was complete. It was the most comfortable space I have ever lived in through so many weather conditions. It was awesome. Do it right!
Rockwool is awesome - I'm just a homeowner that found it at the big orange box store. I installed it in my basement ceiling (garage in basement), and I'm now replacing my attic insulation with it. I always recommend it to anyone that talks about insulation.
Has it cut down on heat loss from the house? I’m planning on this next week!
My father started installing rockwool in remodeling in the early 60s. I've seen it made from rock slag. I've installed it in hundreds of houses. Walls, attics, floors, etc.
It is great sfuff.
Rockwool will eventually absorb water if you get enough of it. I had area flooded and part of it got stuck in water. Just that part became soaked, but it didn't pull to remaining batt, so was just able to cut it off and move on.
Milwaukee marker is also my favorite, would definitely recommend their fastback utility knife! planning on gutting master bedroom this summer and will definitely check this insulation out
Finally a builder who insulates the interior walls! This is super common outside of the U.S.
“Today I’m going to tell you why I went with Rockwell insulation” “this video is sponsored by Rockwell” it’s was free and I got paid to tell you about it, that’s why. 😂😂
I'm fairly certain that both the law and youtube terms and conditions require he say this in the video.

Not sure it is required by law or TOS.
UA-cam is not regulated like tv, radio and news papers.
8 reasons why and this is reason #1

I mean "journalistically".
Matt’s building a new home for his family. Aaron can’t spell rockwool. Enjoy your mom’s basement.
Thanks for the information. I'm going to be building a house this summer and wanting good insulation. I am going to use rigid foam on the outward surface with fiberglass bats on the inward section. After seeing this video, I may be trying something new. I wanted to go with SIP construction but was unable to get a complete bid. First was just quoted for walls. When I told them I wanted the roof to be SIP I was only quoted for over the house/living area of the house but not over the garage. When I requested for the entire roof to be SIP I never heard back. I also wanted a bid for assembly/installation. I called. He was out of the office to be at his child's track meet. I left him a voicemail and sent an email. A week had gone by. Still nothing! Emailed a local contractor to get an estimate for stick framing our house. Next day he contacted me wanting specs so he could work on the numbers. Next day I had an estimate emailed to me. He asked who was doing the foundation, who was doing the driveway, asking if I was needing more than just the house framed up. Next day I had him out to the property for an estimate. The day after I had separate estimates for driveway, foundation, framing, and plumbing and electric. So I decided against SIP even though it would probably save me money in the long run. I'm just going to be very thorough with my insulation. Funny how one person's sluggishness can lead to someone else's opportunity.
Love this series. Will you be showing the landscaping process in similar detail?
Mora 7350 Insulation knife is absolute perfect for cutting Rockwool.
Biggest selling point on exterior Rockwool/ROXUL SAFE/CURTAINROCK 80 versus EPS/XPS can be summed up in 3-words:
Grenfell Tower Fire.
Wrap your house in Rockwool and you get to not die in a rigid board petroleum byproduct fueled funeral pyre.
The hydrophobia and sound deadening are just bonuses to the R-value and fire rating.
what does that mean?
Yes, I wonder why Matt didn’t do exterior insulation. He seemed to love it in prior videos.
The problem at Grenfell wasn't the exterior insulation, it was the flammable siding (aluminum + polyethyleen + aluminum sandwich).
What kind of fabric did you use to cover the insulation in the attic? You mentioned a white vapor open fabric. Thanks!
I'm a big fan of rockwool insulation. I also use it between rooms as well. It does dampen sound quite a bit. Between the living room and master bathroom I can barely hear the tv when watching a loud action movie.
I have some ideas for some non conventional uses of it (exterior). I have one possible application but I would need something like the ridgid exterior version but in a larger sheet and 1.5" thick. Awesome product that has been around a long time and there are so many applications outside of house insulation.
That sound test at the end really sells the product.
If this wasn’t a sponsored video, the host would say that paying double for Rockwool is not justified by it’s benefits. It is more fire and moisture retardant, but is essentially the same in regards to insulating and sound dampening.
Stay tuned Sean. I'm going to make an unsponsored video and justify paying double for Rockwool. Granted I still use high density fiberglass when clients do not see the value of a $1000 upgrade to Rockwool. But I prefer Rockwool, and a $1000 is a great deal for a product that performs better. RESNET Grade 1 is easier to achieve.
@@mcintosh.daughter “Upgrade”?
I've used this in three music studios that I've built so far. It's amazing. No, I didn't get sponsored. But it would've been nice! I will definitely use it again even if I'm not. Huge difference using it.
I will say that, rock wool definitely help dampen sound coming into the house from outside, but after I put on Sheetrock, I noticed that the sounds bounce around the Sheetrock walls as if the rock wool wasn’t there. Just something to keep in mind when you insulate or use it for sound purposes.
so you are saying rock wool is no good when there is interior noise ?
@@lancernightful, That's a good question. I am saying that the sound you make on the inside of the house bounces around the sheetrock very easily. However, travelling through the sheetrock/wall is a different story. In otherwords, if you keep all of your doors open in your house. There is a good chance the rockwool you put on your interior walls will do nothing. However, if you close your doors there is a good chance the sound will only stay within that particular portion of the house instead of resonating through the interior walls. I would say bedrooms interior walls are good places to use rockwool for sound blocking, but all other areas are sort of pointless and a waste of money in my opinion.
That is not my experience at all. I insulated my walk out basement, with huge sliding doors, and even with all that glass, the sound insulation is much better, and now it feels like a room, and not a basement. It was definitely a great bonus,surprise, as I was insulating for cold.
I used it in my recording studio, amazing product.
I haven't used the Safe and Sound, but have used the R15 on our exterior walls (replacing very old R7 pink stuff) and can attest that the sound difference is incredible, before it was very easy to hear a car pulling up in our gravel driveway, now we hear nothing unless windows are open! Also important to me, as you mentioned, is the vapor permeability, we live in a climate that has extremely humid summers and cold winters, our 40+ year old house (with no vapor barrier) still has the original T1-11 siding (except where porches were improperly done and allowed actual water in) because of that ability to dry from either side. Our goal with remodeling this house is to get it through the next 40+ years with little to no issues.
Did you install a vapor barrier when installing rockwool on an exterior wall ?
Love your videos, just makes me realize how poorly built my home is.
With a house that quite you might consider a intercom system for emergency
Excellent demonstration at the end.
I watched a rockwool vs fiberglass video and I was sold on rockwool. I'm doing a addition plus a remodel on the older side of my home. WOW what a difference the rockwool made on the older side of the home. It killed the heat and noise I live in Hawaii where the older construction was poorly done. I'd tell everyone to insulate with rockwool. My AC loves it. I can use a smaller size AC due to the insulation.
