The dangers of #Rockwool

[@jonathangwynne1917]

I've worked with mineral wool for years and I've never seen any of the effects that Cartwright is describing. In fact, it sounds like he's describing fiberglass (which does cause contact dermatitis) rather than mineral wool. I've handled mineral wool without gloves. It is interesting that he describes mineral wool as "man-made vitreous fiber". That isn't correct. That term refers to glass-fiber (hence the term "vitreous"). It would explain why he complained of skin problems after handling it without gloves. There are specific and explicit warnings on fiberglass packaging to wear gloves, goggles and breathing masks. As for his empty speculation that mineral wool is "effectively the replacement technology to asbestos". Even if that were true, it is irrelevant and a sleazy attempt to create guilt by association. It should also be pointed out that Gary Cartwright isn't a doctor, medical research or scientist of any kind. He's a blogger who works with an online publisher called "EU Today". In any case, it is hard to take a guy seriously when he doesn't understand the difference between mineral wool and fiberglass - or even that there is one.

[@frankbeeckman7575]

Here is a toxicologist's opinion: kzbin.info/www/bejne/g4Stm5ymlrWri6c Rockwool was classified as cancer causing in 1988 until additional insulation industry sponsored research "proved" that it did not really cause cancer. Based on this, the IARC changed the carcinogen classification for rock wool (and fiberglass) from Group 2B (possible human carcinogen) to group 3 (not classifiable as to its carcinogenicity to humans). Go find where the insulation institute addresses who sponsored this "new" research: information.insulationinstitute.org/blog/why-some-products-have-a-cancer-warning-label They didn't mention that part. Are we surprised? No. This is common in the industry! Big tabacco sponsered research for decades, successfully "proving" that tobacco was harmless and even healthy! Even their TV ads were informing the public about the health benefits. Since the media was paid through cigarette ads, they went along with their golden goose and many didn't dare to publish a "smoking is bad" research article. When we put the fox in charge of the hen house, what else can we expect? The same story is happening with the phone industry. Cell phones are supposedely harmless since radar is non-ionizing, so we are led to believe. Unfortunately, one does not need ionizing energy in order to get a tumor. Persistant inflammation can cause cancer, whether that is due to bad nutrition, small particles or fibers that get stuck in the lung, persistant stress or lack of sleep. The cause of inflammation doesn't matter! The phone industry has also been sponsoring research that contradicts others research. Due to all this "contradictionary" research, we are led to conclude that cell phones are safe. Just as with big tabacco, some courts are starting to disagree: www.smart-safe.com/blogs/news/fifth-court-in-italy-ruled-cell-phones-cause-brain-tumors-and-determined-it-is-an-occupational-disease 5 G with its much higher energy density is coming because it's going to be a trillion $$$ industry. Who is concerned? Independent scientists and unbiased policy makers ALL over the world: www.5gspaceappeal.org/the-appeal Unbiased researchers do not have the deep pockets to "influence" our mass media and our politicians. That is the sad reality. Meanwhile, rockwool doesn't seem to have a better alternative and world governments are focussing on energy conservation. Such politics may also have played a part in the "non-cancer causing" reclassification. The rockwool safety sheet recommends the use a NIOSH certified dust respirator with an efficiency rating of MINIMUM N95 during the install to protect our lungs from it's "safe" fibers. Ironic, isn't it? files.stifirestop.com/5.%20Safety%20Data%20Sheets%2F1.%20English%2FSDS_Roxul-Safe.pdf

[@TeacherFlash]

this was the most incompetent interview ever. Only one solid point was made by a guy on the left. The scratching on your hands (somewhat) similarly happens in your lungs (BARELY) since those fibers get wet in your lungs and cant be dry sharp and to stitch anymore, their micro-particular behavior changes due tho cohesive properties. take rockwool in your hand and rub it, it will scratch your hand, then do it on the other hand but make it very wet, you will see that it will not itch at all. Further more those particles are easily absorbed by our macrophages or on the other hand excreted by your slime in your respiratory tract. Comparing some substance that can itch a little bit to a cancerogen is just non-sense. So here are official data by various world health organizations which can not be all somehow magically controlled by a company called rockwool with 2 billion in revenue which is quite laughable compared to other textile industries that would be super happy to jump in as asbestos alternative: Rockwool and Slagwool: • A large study of glasswool, rockwool, and slagwool workers in the U.S. analyzing mortality data from the 1940s to the 1980s showed no or small increases in the risk for respiratory system cancer, but no correlation between length of exposure and increased risk. (1) • A study of respiratory cancer among glasswool, rockwool, and slagwool workers in the U.S. analyzing mortality data collected until 1992 reported a small, but statistically significant increase in respiratory cancer for workers employed less than 5 years. However, no increased cancer risk was reported with years of employment or cumulative exposure. (1) • A large European study of glasswool, rockwool, or slagwool workers showed no increased cancer risk related to date of hire or employment length. (1) • In chronic inhalation studies in rats exposed to rockwool and slagwool, no increase in lung tumor incidence was seen. (1) • EPA has not classified rockwool or slagwool for carcinogenicity. • IARC has classified rockwool and slagwool as Group 3, not classifiable as to their carcinogenicity to humans. (4) Only thing that so far did happen was that they put rats for 6 years 6 hours a day to inhale highly concentrated rockwool particles WITHOUT any protection and they noticed SOME scaring. They could not even say moderate or sever scarring but rather wrote "some statistically significant" in other words in real world not significant scarring... lol you know if you inhale regular sand that way you for 6 years 6 hours a day through a tube you will have SOME MAJOR scarring on your lungs. So here is my professional opinion: Rockwool particles size is okay and easy to digest, easy to throw out with slime as well, it is easily dissolved, can be itchy and don't be dumb with it, put on a mask and do the best job you can. Further more if you have a studio with a lot of sound absorbing panels that you may not just cover since it will affect the acoustics of that panel, then make sure you don't move it around, rockwool is very heavy as dust and it falls on the ground, buy a good vacum cleaner, make vacum cleaning your routine and it won't even itch anymore. Further more Rockwool isn't anything new, it has been around for decades and decades and generations of professional workers with rockwool have grown up and died out and of course we would have by now be able to figure out what they were dying of and if it was related to lungs disease. Those two guys gave no facts what so ever, what so ever... So as someone with medical background and someone who was deeply interested in the subject since I was building a studio with my company couple of months ago and needed some truthful reliable and verifiable facts, I have discovered that Rockwool is not lying. Even Russian medical studies in Russia they still use asbestos and admit it is harmful but it is very cheap for them to mine, they admit that rockwool is much safer, to be quite exact >> completely safe. That is basically a country where Rockwool is seen as a threat to domestic industries of asbestos, their medical institutions still gave out reliable information about Rockwool to their population. If you think otherwise, please show evidence.

pubmed.ncbi.nlm.nih.gov/28784145/

[@TeacherFlash]

​@@bobsagget823 Yeah that study says that it takes longer to dissolve some particular rockwool of newer brands under same pH value. So they refer to post 1995 fibers as being the potentially bad ones. So for example In most cases, symptoms of asbestosis take 20 to 30 years to present from the time someone is initially exposed to asbestos. So in theory, yeah... What if that effect really takes so much toll on our lungs and if pH value is all that matters or at least mostly matters in this case? Theoretically anything is possible. You go out now, a car might hit you on the road. The study was not to prove that it is cancerogenic. It was not even to prove that it stays longer in the lungs. It was only to prove that solubility under that pH value is somewhat different. I am not convinced and I'm leaving my studio as it is. I don't like to be dismissive. I hate dismissive people. Yes that study indicates that maybe it is possible that those newer brands stay longer in the lungs. Do they? Well even the study says "Considering the content of respirable fibres, these findings imply that the risk assessment of modern stone wool may need to be revisited based on in-vivo studies of MMFV as marketed (with binder)." So they call for in-vivo studies to see. And I agree, it should be investigates. Still even if something horrible would come out, I don't expect anything even remotely close to Asbestosis. Such studies and implications must be investigated as soon as possible to prevent speculations and possible damage. Being ignorant serves no one. I really tried to have realistic and not one sided view to this topic. So far it stays as it is, there are no studies that prove it is causing cancer or something.

Why compare it with asbestos? They're not the same. Rockwool fibers are single monofilament strands that don't separate into thin fibrils like asbestos, and will not penetrate the cell walls within the body. I guess these twats have never handled a batt of fiberglass insulation before. If they knew what they were talking about, or knew how to do proper journalism to begin with, then they would understand that FIBERGLASS insulation was developed to replace asbestos insulation (not necessarily asbestos products) when it was banned in the UK nearly FOUR decades ago. Rockwool is the latest innovation in building insulation, and is intended to replace fiberglass insulation. You know, that itchy, lung irritating crap that goes airborne just by looking at it. Trust me, those of us working in the construction industry are well aware of the risks of ALL building materials - it's our job to understand them. If you're working and installing ANY fibrous building material for an extended period of time without protecting your lungs, then you're an idiot who deserves a Darwin award.

Before working with fiber glass or minieral wool cover yourself from head to toe with clothing. They sell clothing kits to wear top to bottom for very cheap. Any exposed skin that could be exposed like your lower back, neck, face especially forehead with baby powder. The powder will protect your skin from exposure and drastically reduce or eliminate the itching. Do not ever breathe the stuff or get it in your eyes. Protect Protect Protect.

[@ItsoFototo]

As I am about to install Rockwool in my attic, that will be also a bedroom, I begin to worry. And not only for the time handling the material during installation but I also worry that, in the future, the fibers may slip through the cracks between the rafters and the wood panels and be constantly in the air. Also, the insulation I got is called Rockwool Multirock. I believe it's made in Romania and it doesn't seem to be in the market anywhere else but in Eastern Europe. I wonder if it's yet again another substandard product that is only acceptable in Eastern Europe and not in the West. I noticed how easily the material breaks into pieces, when handling, and there's definitely lots of particles floating in the air. I don't know what to do. I've already spent a bunch of money for this insulation. I'm trying to convince myself that, if Rockwool is so widely used, it's probably not that bad. Here is another video that explains why fibers (glass and those of mineral wool as well) are harmful: "Dr. John Hadley: A Toxicologist’s Review of Fiber Glass and Mineral Wool Insulation Fibers" kzbin.info/www/bejne/g4Stm5ymlrWri6c

[@CostiDima]

If you put the insulation on the inside of the wall you also must add a vapor barrier so there's no reason to be worried about the floating particles

[@crcurran]

You need to seal the penetrations from attic to the living space below as much as possible. Then lay insulation over that and maybe a radiant barrier above that to reflect that radiance from the roof itself or move radiant barrier to the roof rafters while allowing air flow in and out of under the roof from the outside to avoid problems like ice damming. Using baffles can be useful then radiant barrier behind that so baffles flow the fresh air in and out and the barrier stops the radiant temps from the roof (radiant barrier on both sides can help keep the heat in the attic during the winter. With minimized airflow from attic to living space you drastically cut down on fiber glass or mineral wool falling into the living space. As a precaution, things on the top floor right below the attic can be covered and then vacuumed. The good thing about mineral over fiber glass is that it doesn't float like fiberglass; it sinks which can then be wet-vac'd up .

[@johnarizona3820]

One thought to the positive would be to either coat during manufacturing or blend the base material with a metal again during production. Aluminum for example could seal the material but once cut to fit it would be back at square one with the health hazard. Blending the stone while in liquid form with aluminum even to a microscopic degree could produce the same or better characteristics but would reduce any microscopic fly away material. For that matter a non flammable dampening spray, perhaps silicone oil would also reduce the detrimental environmental factors.

[@urigonzalez6300]

I was really hoping for a more in depth discusion as to why its unsafe . Fiberglass insulation used in most homes now makes you itch . Since it is made from rocks it was an easy conclusion that the binding agent would be the bad part .

it's less about what it's made from and more about the structure and durability of the fibers. I.e. they are small fibres that can lodge themselves in your lungs and they're not biodegradable so they stay there and cause permanent inflammation. Same issues with fiberglass.
