We just had rockwool installed in a loft renovation this week. Months of rough work done where old fiberglass was left in the party walls. Neighbors complained a lot about noise, even that they could hear our conversations. The minute the rockwool replaced it, the sound difference was like night and day. Quiet as a funeral.

[@Matt90541]

lots of big KZbinrs definitely seem sponsored by Rockwool but i've heard old fiberglass doesn't retain it's shape as well over time.

Shortly after Roxul was readily available I built a chicken barn addition (50x100' on an existing 50x100') ... the existing barn was done with pink, at the farmer's insistence he wanted Roxul put in the addition... now there is good reason for his desire as between flocks the barn gets washed with a pressure washer so his existing barn had some issues water intruding causing sag and thus loss of heat (and more heat intrusion)... BUT, a year after build he hated the Roxul because the rodents loved it... the claim of rodent proof were greatly exaggerated... Now I know they still make the same claim so I expect that they have since added a chemical treatment to it otherwise by now a class action suit would have occurred.... personally if I was still in construction I'd be apt to use lamb's wool instead of pink or green...

[@teddepalma8057]

Great video! I did a whole room with the rock wool- an old serrated kitchen knife worked great for cutting it. I think it's better than the pink stuff for keeping critters out and for mold resistance, but maybe you could do another test to confirm that one. LOVE your channel.

[@ryanbrown8398]

Great video, love the demonstrations on what actually happens when wet or charred. One thing I'd like to bring up is the pest and rodent factor. Since it compresses twice as much, fiberglass attracts rodents for nesting during winter months. Bugs also have easier access to inside the home. Rockwool is a much tighter fit, providing a better seal on the exterior. Just something I've noticed as an electrician, where I'm constantly working in and around insulation of all types.

[@topherdean1024]

[@jillstamets8448]

Have you noticed that the Pink slides down the wall over time? I've listened to other reviews that mention this... affecting long term R value (?)

[@greggo502]

Love your channel but I would repectfully disagree on the burn characteristics of fiberglass to a degree. When I was a firefighter in the city we constantly opened up walls and ceilings. The fiberglass insulation WITH THE BROWN PAPER backing especially in the walls most always extended the fire upwards. It would climb vertical in the 2x4 space. the heat from the paper burning would melt the pink stuff. When we opened up there was most times a burn or char area that was spreading.Sometimes it would be contained to that wall/ceiling space sometimes not.

[@leatt4693]

The fiberglass he shows doesn't have the brown paper backing, so your argument is null and void!

After the wet, Pink grows mould etc. It compresses, flattens & every time I clean that crap out, it seems to be the preferred nesting spot for bugs & mice (filled with droppings). Over time I believe the Rockwool retains its R-value.

[@diannahall7727]

I love the comparisons. Especially the foam spray one a while back.

[@PhilipHousel]

Jeff, you are such a fountain of knowledge. Thank you.

[@jackfeig1262]

If you are insulating a ceiling, you can bend the rockwool and pop it in and it stays there. I found rockwool easier to work with, quicker less steps,and way less itch. With fiberglass in a wall or ceiling you need to staple it and put a moisture barrier if it is unfaced. The rockwool just goes in. Do to price I don't know if I would do my whole house, but as I have been redoing small areas the price is negligible, so I use the Rockwool. Ironically the reason I bought it the first time is because it was on sale and was cheaper than fiberglass, I liked it much better.

[@valdesigns1346]

This is awesome info. I was just about to go to Home Depot to fix a drywall spot that gets wet in severe storms. Now I know which one I want for that spot! Thanks! Great channel!!!

[@FragThePlanet]

Because of your videos and help from a friend who built house, I've saved thousands on labor costs by doing a lot of work myself... So I went with the Sound proof Roxul... I'm only doing a couple rooms here and there so it's not a huge cost, maybe a couple extra hundred bucks. However if you're doing an entire house I could see how the pink stuff could really end up saving thousands. Thanks for the video very informative.

It's great info, for sure! I'd rather hear this stuff from this guy who DOES the work, than from someone theorizing about why it works.

[@simpsonmbm]

Great video..thanks! I ended up using Rockwool for my cathedral ceiling in an addition because the R value would allow me to get above R38 in the space I had where fiberglass needed an extra couple inches, otherwise, I'd be compressing it too much. So similar to your comments in your video, I have a mix of pink stuff largely for the walls and Rockwool for ceilings. It's also nice that it stays put in-between ceiling joists without needing anything to hold it in place prior to drywall. I'm planning on still using a vapor barrier even though I think I saw that Rockwool is ok for use without one. I just don't want to chance it. Thanks again!

[@dsfodor]

When I open a wall during a renovation, I find the pink stuff has always lost its fluff and in turn it’s R value. Roxsul type insulation fills a cavity way better and you don’t end up with dead space that is missing insulation. Pink is old school.

[@HectorSaIamanca]

Fiberglass is so dated owens corning is making mineral wool now that really says something.

Its rated to hold its r value for 20 years. I never understood why but it makes sense any water or settling over time and its garbage. The mineral wool is good for the life of the house. Yes its more expensive but if you plan on passing the house on to future family members its probably worth the cost.

This problem is only on the walls not the attic. So it makes more sense to use the pink stuff in the attic. Right ?

Or hire a pro to do it for you. Pests like mice and bats can cause thousands of dollars in damage. I was recently working on a house that had 4 inches of bat poop in the attic. They had to hire a restoration company to remove the bat poop and all the blow in insulation, properly clean and disinfect. Then hire another business to blow in new insulation. I'm sure that whole process cost around 10k. Then finally they hired a guy to seal off the attic from pests. Should've just done that from the get go.

[@carollshelby500]

Great video. I was originally going to go with rockwool. But you now have probably changed my mind. I assumed the rockwool was vastly superior.

[@liquidrockaquatics3900]

3:50 let me just add that as a plumber more than once I saw the ceiling(s) collapse because all the pink insulation had soaked up water like a sponge and held it and collapsed the ceiling. Yes there were always other factors involved. No I didn’t have a chance to test against rockwool. Irrespective of that, the insulation around an outside hose Bibb in all directions for 8’ or so should be rock wool if you’re going to use it because when a leak occurs, it generally hits the entire 4x8 area if it’s finished (if you are lucky that portion of the ceiling will collapse quickly) but what is more likely is that water starts filling the joist cavity in the area where the hose Bibb is located; once it starts to fill, the ceiling below tends to absorb water and start to sag, creating a pond effect. If you’re lucky, the water will be contained here between the joists, but typically this is where things get really bad. After the drywall starts to deform, it makes gaps under the joists and water starts flowing into other joist spaces. From here, water will fill a finished ceiling until failure. Ironically, the better construction a finished basement has, the worse things tend to be - same as with super shoddy construction. The super shoddy construction hold just long enough to fill with water before collapsing but never really had a chance (because each sheet of drywall on the ceiling had 6 screws holding it on + tape (can’t make that up)) and the well constructed ceiling is fastened so well that it gets completely full of water before showing any signs of a problem. Morale of this story? Take your damn hose off the spigot before the winter. Also, walk all the water out of that too so it doesn’t freeze.

[@Scorpiomaj27889]

Something I use it for, even thought it's not called for, is in walls with a 220v electric in-wall heaters. Most modern heaters are very well designed with extra safety features, so a fire is unlikely, but not impossible. Also, in a cold wall, I could imagine the hot and cold creating a moist area - supposedly rockwool is more mold-resistant. (Mold resistance is also a reason I use this on top of my HVAC trunk lines in the basement.)

[@user-hw7hl4td9c]

by the time the fire is into the drywall, it's so much heat, and it's so widespread that I imagine the insulation basically melts like cotton candy after 10 seconds.

[@joedance14]

Your videos are always instructive and fun. Thank-you. Regarding the choice of insulation, the attic gets dirty, and South Carolina gets very humid and damp, regardless of season - and that humid, damp air circulates through the attic. We need insulation in the attic, but I guess I’ve developed reservations about “the pink”. I am also wondering whether to go with a radiant barrier, traditional batts/blown-in, or both.

Otherwise it would have taken much longer. Clean up still continues. There are still people homeless because their homes are too damaged to live in. There's more work than contractors. Building supplies are in short supply. Some contractors have taken it upon themselves to travel to other major cities to pick up supplies because it would take less time than waiting for them to be shipped in. Most schools in that area started yesterday. Our school district delayed a week and started the end of Aug. but we didn't have the damage to school buildings like the city did.

This video is pretty much spot on. A couple of other minor notes for new renovators: * Some people have a very negative, almost allergic kind of, reaction to fibreglass. My wife is one of those people. It doesn't bother some, like me (thankfully). Rockwool does not have this problem * All fibreglass insulation is the same. Pink, White, Orange, whatever. It's all made to the same specification so you will have a consistent install no matter what is available in your area. * Do wear a filtration mask when working with fibreglass. Inhaling the fibres can cause long term health problems and the fibres are going to be airborne while you're working.

If you've ever worked in an attic crawling around in fiberglass, you'll notice that your lungs, esophagus, airways, etc. hurt/itch afterwards, because you've breathed in all the fiberglass particles. This is similar to asbestos. Asbestos is "safe" to be around, but whenever working with it, i.e. tearing things out and aerating it, you breathe it in and that is not safe.

[@anthonyjoe9139]

@@user-nh3gu1ge3d I didn't misunderstand. I wouldn't use it any more than I would asbestos. It's nasty. The attic is full of the fibres. The crawl space is full of them. I had a storage locker insulated with that garbage. That stuff got into EVERYTHING and no one was AGITATING it! Every box had that crap all over and in it. Tell me the fibres aren't working their way into the house. Who knows how much of the dust is that crap even if it's not as obvious as in my storage locker. I can't go into the attic or crawl space without a mask that crap is EVERYWHERE. It is garbage! I would never use it even for a chicken coop. It ought to be banned and the companies that make it ought to have to pay to remediate the damage.

[@user-nh3gu1ge3d]

@@anthonyjoe9139 Errrr, what? I think something was wrong with your house, bro. Every house I've ever been in has had pink fiberglass insulation and I've never seen that issue. Hundreds of structures, including businesses (look above the drop ceilings and there's probably pink stuff). Maybe your home used inferior stuff, had a pest problem, an issue with humidity, etc. etc. etc? Idk but sounds like a you problem. It's fine unless you agitate it.

I'd love to see a comparison between electrical, air, and hydronic in floor heating.

I think the only thing I've ever had anything like an allergic reaction to is pink insulation. Rocksul , no problem. There is the critter issue as well.

Roxul insulation is just what I need to use in a Garage Wall that Has already been Drenched by a Broken Water Pipe. Thank You for comparing the Insulation!

Definitely wear a mask when cutting, and handling insulation 👍 protect your eyes 👀 also

[@angellas.1314]

Okay. But which one will collapse in the wall faster after 10-20 yrs. My pink insulation is now collapsed inside the walls. So it’s basically non existent insulation and my walls are FREEZING here in CT. Can you advise on that?

[@drackar]

The mineral wool won't collapse. Pretty much ever.

[@angellas.1314]

Drackar ....Thanks for confirming. And that’s why I had my basement insulated with Roxul.

[@roweboat]

They are both great! I like mineral wool simply because it holds its shape. In some situations the rigidity can save a lot of headache =) Can't argue about the cost though! haha

[@augustreil]

That's why in a 2X4 wall you would use an R-15 fiberglass batt, stiff as a board. A 2X6 wall, you would use an R-21 batt. Ceilings, an R-30 high density batt, Etc.

[@dalereitnauer]

the best tool I have found for cutting fiberglass is an electric turkey carving knife. it cuts clean and quick and does not appear to dull. I never tried it on Roxul but i believe it would work well on that too.

[@denalikid72]

We need a spray foam (closed cell ) vs Rockwool comparison! Great content

[@scorpion068]

Sprayfoam is the king of insulation but $$$

[@narmale]

there is none, spray foam SUCKS... try cutting in something after you spray it... not happening

[@adblink1379]

And rigid insulation panels! (XPS)

[@narmale]

@@adblink1379 they just installed some of the 4" xps at the job, $40.00 usd a 2x4' sheet... and they were bringing it on tractor trailers

[@ryanbrown8398]

Building materials better be completely dry before spraying closed cell. Also, all wiring needs to be run with no twists or kinks, or it might overheat and melt, breaking the circuit. Troubleshooting electrical issues creates a huge mess of torn out foam, that usually never gets reapplied by the general contractor.

[@stephenholland6328]

I just did a drywall tear off and replacement in an 8x8 section of wall in the kitchen. Since I was down to studs my wife suggested we sound insulate because a bathroom was on the other side. The sound muffling was very good with the rock wool. However, where there were pipes in the walls the rock wool was very hard to install. That stuff just does not compress. I had to cut lots of parts away to wrap a around the drain and vent pipes in the wall. If I did it again I’d get a mix of rock wool and fiberglass, stuffing fiberglass in the little nooks and mineral wool in the bigger areas.

[@MT-fl1eb]

Great comparison thanks!

[@T.E.P.]

Yes!!!!! Perfect

[@bennewfield3038]

I'm loving the roxo or mineral wool for a few reasons. The biggest it doesn't leave me itchy lol. With the pink fiberglass insulation I find that I need a mask, long sleeve shirt, and gloves. And I tape the gloves to my sleeves. The first time I worked with mineral wool I was in love 😆. Way way easier to install. There's no itch to it and I find that it not only makes the house feel warmer but it seems to be a good sound barrier as well. Yes it's a little more expensive but worth it I say.

[@glenclarke6866]

This was a very helpful video. I was under the impression the pink stuff would would burn like crazy. It kind of makes you wonder why it doesn't meet the fire code requirements like Roxul safe and sound

[@HickoryDickory86]

Fiberglass is technically also a mineral wool in that it's just spun glass, which is made from sand/silica. It doesn't burn, but it can and will melt. If it has a kraft paper facing, though, that can and will burn and cause the fire to spready vertically within the wall cavity.

[@kyarakll4os7]

Can you do a video about dense pack cellulose. When it gets wet, dry time(after it gets wet) fire, cost, ease of use, different applications?

[@cgravelle]

One thing I would add, is if you have to try and pull it behind any strapping (or other) when doing a retro installation. The fiberglass is easier to pull through, the mineral wool just pulls apart.

[@jasonkimmel3061]

I have been itching this whole time watching you handle the pink stuff.

[@AndrewMiguelez]

This is so spot on. Rockwool/Roxul is awesome stuff. But the modern fiberglass is so close, it usually doesn't justify the cost. Ironically, you mention Mapp gas vs propane and I see the exact same comparison but you strangely pick Mapp gas... 130° F difference (3.5%) and a substantial increase in cost.

[@bigbob3772]

The BEST trait of rockwool is NO MOLD- unlike pink stuff.

[@CreativeMechanic]

Zip sheathing vs regular OSB and housewrap!! Also insulated vinyl siding vs hardie plank!!!!

Adding insulation to my attic. Went with the pink, couldn't find Rockwool with more than R22

[@AmosAmerica]

Thank you for this post! It's extremely helpful. I am doing sound insulation in my apartment and my upstairs neighbors seem to like to share their water with me via my ceiling. I will avoid the pink as I need an insulation that will dry out.

[@buckrussell1403]

Awesome comparison Jeff

[@davidawilliams8603]

I have a stand alone brick garage that is over 50 years old. I would use the mineral insulation inside the ceiling joists. As of right now the roof subfloor is exposed to the air. It gets FREEZING in there in the winter so I hope that mineral insulation will help.

[@davidshaw5126]

Rock wool is way easier to work with when doing walls. I use a large bread knife to cut it. Yes a little more expensive but time is money.

[@narmale]

alittle? its 4 times more expensive...

Glad i watched this now! Wad about to put the vapor barrier on without stapling the insulation white stuff to the top seal. We have currently water damn issues i did notice before it was stapled. Its a modular home so thought maybe that was for transportation already completed.

[@nytrusbk]

Jeff i had no idea... i have been wrestling with what to use in my basement for a while as we clean out the junk, piled up over the years..... so if i was to follow this i would mostly use Pink and some Roxul around like the water bib and base and if i get to it the behind the bathroom wall.... and likely the ceiling to help with sound damping

[@brucej99820]

Cool, now I know to get Roxul. Good for Alaska because if you ever happened where oil ran out during winter. You know the house going to be covered in frost during night winter

[@benhaze1010]

Just doing some renos and finding out that brick walls are far less water proof when seeing from inside the house out. I would definitely be more inclined to using mineral wool after seeing this comparison.
