I bought this as a gift for my friend ru-vid.comUgkxcZqgZ8Ynkiz5n_LxIWRlAicuzmz5kCHG who is just starting out in the world of wood work. He loves it!! There is a great section on different wood and what to use for what kind of job and a similar section for tools as well. The projects in it are things you probably would have a go at with clear instructions, pictures, videos and diagrams throughout. Great for a beginner/amateur wood worker.
Another benefit to rockwool is its end of life use. I operate a gravel pit and often take soil from building sites for pit remediation. Not long ago i received a number of loads from a recent home demolition. The crew had done a good job of separating concrete , siding and all other debris from the soil however the material was scattered with pieces of foam. Touch foam insulation with an excavator and you instantly have hundreds of bits of foam board which can not be separated from the soil and that foam is there as a pollutant for hundreds of years. Rockwool on the other hand can be used as a soil amendment I understand that it can even be used in organic potting soil. I used spray in open cell foam in my latest renovation but from now on will stay away from plastic foam products or at least do more research on the products I do use
Rockwool is the best. I used it for fire break and sound proofing between walls and ceiling during our rental suite reno and in the exterior walls. Sound was no longer an issue in the house! (We did use double layer and rez bar). Heating cost in the rental dropped 50%. We had a water pipe burst a year after the reno and when we opened the wall, the insulation had drained completely and was dry using a meter the next day. Studs retained moisture much longer so we used a dehumidifier for that. The insulation is so easy to install because it maintains it's shape and doesn't flop around. Great stuff!
As an amateur with woodworker, i typically feel overpowered with the entire arrangement ru-vid.comUgkxrYREG3-7f1Aqk9ams3ZESRNzGnfdUtyQ . Be that as it may, this arrangements drove me through with much clarity and effortlessness woodplans. Works i now work like a genius. That is great!
I love this stuff. I remember doing my theater seven years ago and it was a pain in the butt to find Rockwool. Now you can buy it at every Lowe's around me. So glad they have come up this far.
just redid a kitchen, we layed metal studs with 5/8 sheetrock and rockwool . it was sufficiently strapped to handle the weight on the ceiling My late father put rockwool and 5/8 sheet rock throughout the house before the days of youtube :) , so I had to follow through in this remodel. So happy to discover how much he thought of after the fact :) :)
I really like using Rockwool. For those that haven't it is exactly like Matt says he isn't embellishing it's qualities. My only complaint is that it is super itchy and make sure to wear a good mask during install as you will inhale the small fibers and you will be coughing it up for a while afterwards. I have it in the wall between the living room and master bath and I can turn the surround sound way up and you can barely hear it. My only complaint is that some of the products are kind of a pain to get in small quantities. It is far superior to the old mineral wool that was popular back in the 50s to 60s. That stuff was very poorly manufactured by a company here in Texas. The batts were undersized and lots of granular slag left overs in the batts and in the loose attic insulation.
Being from the commercial side I've used this product many many times over the past 25 years. It's the best stuff out there. As an apprentice, the old timers taught me to use baby powder before using rockwool/insulation on any exposed skin. We will cover our arms neck chest and face. Then when you get home you shower with cold water first to keep your pores closed for a good rinse. The back of my neck was always that one spot if i forgot i would definitely regret. WEAR YOUR MASKS and SAFETY GLASSES PLEASE! Being over 50 I can say I wish I wore a mask more as a young man. Thank goodness I am a Supervisor now and those days are behind me.
my old house was fully insulated- interior walls too- with rockwool,best stuff ever. bed rooms and liv room were fantastic for keeping noise down from kids and tv, along with solid core doors
Could you maybe tell me why my small bathroom in a house built in 1964 is always a walk-in freezer in the winter? I added new Marvin widows 2 years ago, but it’s still freezing in there! How can I make it more comfortable in there?
Rockwool has been my go-to for insulation for years now. Great to work with, cuts easily ( I typically just use dollar-store steak knives!), easy to install. As some of the other comments said, I also use this for interior walls when I can, especially around bathrooms - really cuts down on noise.

It’s great stuff to use! I always use a 12 inch drywall knife to help me install it, you can just slip it between the stud and the insulation, and you don’t have to worry about the friction that will punch it up.
Actually I shot this one last week! However, I don't have a video for Friday 🤫Have a few ideas of what to shoot while my jobs are shut down. Never fear, I haven't missed a Tuesday or Friday upload in over 3 years!
When I purchased my home here in NC I was told that there was plywood under the aluminum siding. Well, it turns out that I only have very thin sheathing board and the aluminum siding. (Fun.) And a home that was supposed to be constructed with 2 by 4 with 16 on center construction seems to vary in width between studs. (More fun) I appreciate the info as I seemingly will need to "rebuild my home in place. I recently used Rockwool to insulate between a bathroom that has a laundry space included.. I'd love to make my way around the house with the product. Thank you again for your videos!
I'm in NC too and all too familiar with the building practices here. Lol I am going to insulate my basement ceiling joists for the floors above. Trying to figure out of I need to cover it..
I use Safe n Sound in the wall between laundry/mech room and the media room. The safe n sound absorbs a wide range of the frequency band. My walls are double 3/4 inch sheet rock on each side with gleen glue between. I can have a full load of laundry going,, water heater running, and furnace blowing and its still quiet in the room.
Matt, can you detail how you are doing your windows, roof, and your old brick walls with the exterior insulation? How do you add insulation to the brick and still have an air gap? How are you framing your windows for it? Stuff like that.
Matt is correct in his assessment of this product. It is the only type of interior insulation that should be allowed in U.S. home construction as far as filling the cavities with other than foam. Foam is risky if not installed properly, and it is not a DIY product in my opinion. I have installed a lot of fiberglass insulation in projects over the years, none even come close to this product. It completely fills the void, cutting is easy and precise around outlets. If you want to build a structure that requires less energy to heat and cool this product is the essential product to get you there. It is not cheap, but there is no doubt this product is going to pay you back in energy savings and the increased noise reduction is just an added bonus, as is the increased fire protection and the fact it will not absorb water. This product is hard to find, must be ordered in special order, but is worth the extra effort. Thank you Matt for bringing this product to the attention of so many people.
Used this stuff in my basement finish. Wow.....sper easy to use, fast to put up, and does a great job. PLUS you get the added protection of fire break protection if they fully fill the wall cavity. Very nice product.
Hi Matt, it would be very helpful if you could make a video for the young tradesman or the people on the edge of pursuing a trade. I have been working construction for 3 years and am a Junior in college. I’m not sure which direction to pursue. God Bless!
Mr. Matt, I always enjoy your vids & learn something new & exciting every time. My Builder/Structural Engineer Husband who usually handled more of the technical/materials/math/best practices, was killed before we had a chance to finish our basement on our new construction home. *guess I did more manual labor & coordinating _with_ him. It’s all roughed-in, but it seems there’s still so much to do. We physically built our houses together so I should’ve paid closer attention. 😞 Now I’m not sure what to do w/o him and I don’t have much luck with subs showing up, not being kinda creepy &/or listening to me (unlike HE did). Now I’m _trying_ to finish it _(or parts of it I can afford)_ myself as much I can _(no choice I guess)_ . So I’m gonna try to do it myself, even if die trying. 🙏 Prayers appreciated.🙏 He had already started to install safe n’ sound Rockwell insulation in the basement ceiling under the the main floor so I’ll order more & finish that part. Looks like we still needed to insulate the basement rim joist too.🤦♀️ Lots of how to vids on rim joists tho. *QUESTION:* Can Rockwell safe ‘n sound be installed ON our daylight basement POURED CONCRETE VERTICAL WALLS _(with or w/o some kind of vapor barrier???)_ OR should I just stick to using foam boards for that (& what kind of foam boards, glue tape, etc....that’s NOT the MOST expensive) on the vertical concrete walls??? Spray foam is out b/c $$$$$$. 😞🤦♀️ Any advice you could give would be greatly appreciated. Thank you in advance & keep up the excellent work in the construction industry. P.S. - You don’t happen to fly out to other SE states to ‘consult’ do you?🙏
I'm a remodeler in Hampton Roads area of VA. Seeing many houses from the 40-60's I can say that over time the one of the issues I see as a remodeler on these older homes is the shrinkage and failure these many other types of insulation. If Rockwool won't shrink over time then I'm SOLD because it won't FAIL!
I actually learned of you On RR Buildings with Kyle. You really do have a lot of informative content on your videos. Thanks for sharing your knowledge!
I'm remodeling a 1904 brick school house in Minnesota, and was wondering if using rockwool against the brick is good or do I need to use a rain screen? This is a full gut job
We finished 1100sq ft of our basement and used safe n sound in all the ceilings and interior walls around the bedrooms. We had the exterior walls sprayfoamed. The safe n sound has really helped keep noise transfer down.
Great video, just a note Vancouver Canada is not as cold as Chicago. It's probable the warmest city in the winter in Canada compared to say Edmonton Alberta.
Check out Matt with the multiple cameras going. Video quality has come a long way since I first subbed. I recently used Rockwool to reduce sound transmission in a common wall. Easy to work with and made a noticeable difference.
Thanks Matt for introducing me to the product. I like the sustainability part of it a lot! Question on how it works from a water vapor perspective. You did not mention if it needs a moisture barrier like regular insulation does and does not appear to even be an option to order it with a moisture barrier. I am looking for something to insulate my lath and plaster walls on my 100 yr old SoCal house. This seems like a good candidate.
Matt, I'm glad to hear that you are working with some builders from California. The desert southwest is a totally different animal, as far as insulation strategies go, than the North, South or East. I live in northern Nevada and we have cold, dry winters and hot, dry summers. Please give some insulation strategies that will work better in these type of climates. We feel left out!
Hi Matt was wondering if you were aware of the wall building system called OSBlock. It's a new product from Quebec, Canada. This product is right up your alley. Hope you get to see my Post.
Rockwool hilarious when I saw it in title . I had to comment on this . I used to grow the best weed using rock wool ten years ago hydroponically. The best weed is always hydro grown out of rock wool , compared to today’s crap soil grown. And bugs will crawl in it through it if it stays wet . And it stays wet if water gets on it and soaks into it and water source isn’t fixed. But insulation value is one of the highest value like he says
This is just totally wrong. Rockwool is extremely hydrophobic. The stuff you used wasn't this stuff, it is a kind of slag wool material purposely designed for growing plants in.
You are correct Jody! I purchased a bunch of R23 Rockwool for a storage building from Lowe's. They delivered it on a rainy day and when they dropped it off at my house I noticed a few bundles had gotten soaked. I was curious so I busted open one of the wet bundles. I left it inside a dry warehouse in the middle of the summer for 3 weeks and was shocked when I could squeeze it and water still poured out. I called Lowe's and told them about it and they said to bring one of the wet ones back so they could look at it. They refunded me my entire order and told me to throw away the rest. I put in my garden and had one hell of a pumpkin patch. I found out Rockwool Comfort Batts are definitely not Hydrophobic 😂.
I put 2 layers of 3.5" Rockwool R-15 batts in specific attic ceiling areas to replace 12" of blown in fiberglass after some renovations. Summer hit and now midday sun the ceiling with 2x3.5" Rockwool batt area of ceiling is 73F, blown-in fiberglass areas are warmer to touch and measure 75-76F, while the AC thermostat is 72F. That's poor results for all that blown in fiberglass. Looking forward to using more of this product as I reno more.
I us it around wood stove installs because it has the 2100 F degree temperature rating, it is a good shield for plumbers to use while soldiering pipes around wood studs because it a great heat barrier. Save leaving burn marks on Studding in new homes, leaves a professional look.
Matt, after the first video I saw on Rockwool, I changed to Rockwool for the insulation on the addition I am building. Love the product. It's hard to find in Northern Wisconsin, but I finally found a wholesaler who had enough in stock. Now I have to decide if I want to put comfort board on the exterior. Thank you mat for educating us. You're doing a great job. "Walk with the KING and be a blessing.!"
Thank you Scott. The LORD has blessed me greatly in so many ways. I can't wait to see how HE works in this crisis. May you see HIS hand upon your life in new and exciting ways.
Hey Matt keep up the good work I am a big fan of your shows and use your commentaries with my clients to explain the pros and cons of all types of building materials and building processes . I enjoy your humble approach to failure anyone that builds at times will run into a oversight in applications . With a good attitude failure can create a determined state of mind to get it right . We are all desperately want to avoid catastrophic failure whether financial or structural life threatening disasters . Your program is part of my Continuing Education after 38 years building new and renovating old houses . Cheers
Used rock wool to insulate walls and ceiling in my basement around a theater, bedroom and bathroom. It was easy to install using an electric knife like you’d use to carve a turkey. Very happy with the product.
I’m looking to use this in my basement. Did you just use it between the studs? I have a one inch gap between my studs and concrete and wondering if I should leave an air gap or put something against the concrete as well
@@Moonkey-d4b I used it between studs, not in the gap between the foundation wall and the studs. I think it would hard to get in there and unnecessary.
@Matt Stephenson thanks for the fast reply. Just trying to figure out how im going to do it. So you have an air space and nothing against the concrete?
@Matt Stephenson after tons of research it’s been a mix of opinions. Some say to leave an air gap so things can dry out if they ever get wet. Other days use rigid or spray foam against concrete and bats between studs. The research has only stressed me out
I have a 1960 home. There was a drop ceiling I took down. If I place the 16 on center with Rockwood will I need to put plastic stapled to ceiling joists before placing my tongue n groove ceiling? Home is in The Appalachia mountains, NC.
Hey,Matt. You should do a show specific to Gulf Coast elevated building. Lots of water and possible wind events, but we really want to keep heat out. Would love your review of hurricane sustainable builds.
It would be neat if there could be product made with a high enough density to be used as an OSB alternative, or a Rockwool backed steel siding/roofing product designed to be used under hardie board siding/slate.
@@angellas.1314 I guess you just need to call around your area and see if anybody manufacturers this near you. It's just Rockwool with sheet metal glued to the surfaces.
Great video. I live in the northern midwest and want to insulate my detached 2 1/2 car garage so I can try and do work in it during the winter months. I know when it gets below freezing it will still be a challenge to work in without a heater, but how can I keep it "warmer" than the outside? What product is best (and R value)? I don't have drywall, just studs for now. It does have an unfinished peak meaning no false ceiling and an attic. Also, is there something I can do to the concrete slap to improve warmth? Thank you.
I needed to add a bedroom and decided to subdivide the "man cave". Because of all the potential noise in the common area, I decided to insulate the bedroom walls with Rockwool. It has done a fantastic job reducing the sound transmission. It was intended to be a temporary room, but it turned out so well I'm planning to make it permanent. It was my first time installing Rockwool and it was a bit more fragile than I expected. They do well most of the time, but if you're too rough with the batts they will break apart. It is convenient though for filling in small, odd shaped spaces and working around wiring. It was also dustier than I expected and a little itchy. I agree a mask, gloves, and long sleeves are a good safety tip. I am looking at building an age-in-place home (at least 40 years) and I'm definitely considering it for that project. Up here in the northland I'm looking for energy efficiency and low maintenance. One thing Matt didn't mention is its mold resistance, mostly because it doesn't absorb water.
Comfortboard being made from recycled material was mentioned. Does Rockwool have a recycling option or program for recycling used batts? I spent 9 years in agriculture builds. A lot of Rockwool batts went to landfill during expansion projects. Very little was reusable into the new build.
I have a problem that I think Rockwool may be the answer too...my sump pump is located directly beneath my 6 month old babies bedroom and when it ejects at night it wakes him up from the sound and rumble it makes ejecting...I thought about using the Safe N Sound in between the joists...any other cost effective ideas on top of this Matt? Much thanks in advance and hopefully some sleep!
Great video, Matt.thank you .. I have one question. I live in PA , my attic has no insulation at all . But roof does have faced down fiberglass insulation.I plan to put Rockwool between slap . Do I need vapor retarder under Rockwool? Thanks for your reply..
Great Channel Thank You and I'd like your opinion: 1962 Phoenix AZ home 4x8x16 with the famous interior 1/2 inch furred out silver shield lined drywall as my only insulation. I'm going to stucco the exterior and would like to insulate. Rockwool? Foam Panels? Other options? Your opinion?
Found your videos and have become a big fan. I want to Install Rockwool R30 insulation in the garage attic above my new wood shop as I am also installing a mini split unit to co trip climate here in Central Florida. I have been looking for mo the and no one seems to have the R30. How can I find it if you know?
Large Hospital/ research center that I retired from only used Rock wool aka cotton candy aka itchy wool. Was fun fishing say a MC cable from a high ceiling to a receptacle. Great for reducing sound transmission. They also only used 5/8" purple moisture resistant sheetrock.
Can you use comfortboard in place of safe’n’sound or comfortbatt? We have a few bags of confortboard over and would want to see if we can use it before we spend more money to buy comfortbatt/safe’n’sound.
I am building a house in Central Kentucky. I have a daylight basement with two concrete walls, ten inches thick, earth exterior. I want to use an alternative insulation to foam, and want feedback on using the Rockwool insulation in lieu. I already have stud walls (16 on center) along the concrete walls. I cannot use the exterior product against those same walls. Can you give me some feedback on Rockwool against a concrete wall. Again a day light basement. I will have geothermal as my heat and cooling source.
You should do a cost breakdown on energy savings vs extra money spent on exterior insulation. I would be curious how many decades it will take to get a return on the investment or maybe the value of the house goes up and you get your money back when you sell.
I just built a wall in a financial office to divide the room, used 5/8 WB, Acoustical Sealant, Rockwool Safe & Sound, and an exterior door, the 2 rooms are dead quiet, they can talk on the phones and not hear each other, and the client is very happy. Great product knowledge I learned from Matt, thanks buddy keep up the great work!
I am getting ready to insulate my woodshop as soon as the electrical is completed. I have been considering closed cell spray foam (to close in the gaps....long story) and then install batt insulation. After seeing this video I am thinking about putting the Rockwool on top of the spray foam...thoughts???
I have noticed that they don’t make houses like they used too. They are mostly made from wood, and the price for them are just as high. What do these products do for a brick home? Or is there different kind of material used for brick homes?
Hi I'm trying to isolate my wall because of noisy neighbors. Could I use 50mm rockwool or do I need to use 100mm? Also what plasterboard do I use over the top? Standard plasterboard or sound proof plasterboard? Thanks
We want to replace our wood exterior with fiber cement siding. From what I can gather from your videos it would be the zip system with an overlay of rock wool. Then slats down the studs to connect the siding. Am I missing anything?
Can the Rockwool Comfortboard come in 4x8 sheets and be used on the exterior of the foundation wall for insulation, termite prevention, bulk water shield down to footing drain, and protect the waterproofing on the foundation wall during backfill?
would love t see you do a video on two less common insulation types here in north america. Those would be rigid wood fiber insulation (like Gutex) and wool insulation. Both have very good characteristics/qualities and from my perspective cost and availability are their main drawbacks. There is however a company in Maine working to open a rigid wood fiber insulation plant and there is a company in Oregon using processing domestic wool for insulation.
i wonder how the safe'n'sound compares to fiberglass bats for sound transmission in floor joist applications. The rockwool batts are 3" thick vs a fiberglass batt which is 9.5" thick. The prices are near the same but 3 times the thickness with the fiber.
Sound is only half the battle. Without stopping vibration as well it's a losing effort. Fiberglass has very good STC ratings as does Mineral wool. The lost component in this video is a good stud isolator like OC Energy Complete or GreenGlue on the studs before installing drywall
He is right about the thermal bridge. And the only way to avoid it, is by insulating trough the exterior. That is what the builders are doing in Portugal. And if we insulate inside we increase considerable the thermal insulation.
We used about 7 pallets of the different forms. They are all basically the same item safe n sound is a little denser, the r30 is 2 r15 molded together. Makes you itch for about a week no smell, particles should be swept up after all insulation is done if it gets embedded into drywall then painted over you will be left with a rust spot in a few months. Reduces ,ore of the higher pitch sounds mid to lower bass sounds can still come thru by stud transfer
Since Rockwool sheds water and is vapor permeable would it be ok to use it again the roof deck between the rafters? I am working with a state program to redo the old insulation and get to code, they will not do spray foam. I have breathing issues and would prefer not to use fiberglass or cellulose blown of any kind. I lice in MD Eastern shore too.
What are the benefits/cost difference between using Rockwool or ZIP-R on the outside of the house? Considering building, and I live in Ohio. I had been seriously considering ZIP-R until this. Is ZIP-R vapor permeable or do I need to worry about that if it is essentially a vapor barrier on the outside of the house? Vapor transmission/buildup is a big concern for me in the climate zone I live in. Great content, thank you for all of the valuable information!
Zip-R is not vapor-permeable, but it's fine as long as the inside surface of the foam never gets cold enough to condense water vapor. For Ohio, where winters are cold but earthquakes/tornadoes/hurricanes are less of a concern, you'd probably want the thickest version with 2 inches of foam.
I swear I saw you talking to someone in an attic and it looked like they had rock wool right up against the roof sheeting. Meant to go back and review what you said about that but can’t find the video. Are there any vapor concerns with rock wool directly in contact with sheeting in that application or does it pass vapor effectively enough to not rot out the roof from the inside?
Matt, Im remodeling a home built in 1925 in a northern climate. I plan on using rockwool on the exterior walls. Would i need to cover the rockwool with a permeable vapor barrier on the inside before sheetrock??
Andrew Sullivan : Not exactly sure where you are located, but I'm a builder in northern Utah (Climate Zone 5B) and I DO NOT install any type of vapor barrier twix the drywall and studs. edit: After thinking about this, don't do what I do just because I do it, if that makes sense, because there's a lot more to it. The idea is to push the dew point "outside" the back of the osb. As long as you accomplish this then you shouldn't need any type of vapor barrier twix the drywall and studs in ANY climate zone. The reason why older homes like your 1925 model have survived is because they are so full of leaks they cannot help but dry... for the most part. It's easy to see though when an area hasn't dried because those are the rotted out and moldy areas.
@@TrailTrackers Pretty sure Lstiburek says about the same thing about cold climates. He supports permeable to the exterior and semipermeable to the interior. If I recall, flashed and sealed drywall with semi-permeable latex paint was the recommendation.
@@nicholassullivan867 : Oh dang it... While reading your comment I also read @Andrew Sullivan original question again and I see that I misunderstood his question. When he said, "...on the exterior walls", I thought he was talking about exterior to the sheeting. Sorry 'bout that guys. What I said is true imo, but I don't think it answers his question.
Well mineral wool is a batt insulation that can suffer air infiltration and R-value loss if left exposed. Similar to fiberglass without an air barrier back in the day. Putting a VP AWB OUTSIDE the insulation would be wise. Even if it is just a secondary barrier as it can be tricky trying to detail back into your openings
It's a shame they don't have some type of blown-in product for attics. I understand you would lose the "compactness" of the product but I would think they could engineer the product so it's in real small "chunks" that would settle close together. I want to remove my blown in white insulation in my attic and would really like a better, more dense product. Any ideas?
Odd question. Since comfort board is vapor open, what would happen if someone used it to insulate the interior of an old historic brick house? Obviously worried about the walls being able to dry out, hence the question.
Can you put this near plumbing? Every time I use the shower you can hear the water in my dining room wall. Can it sound proof the water running through?
