As an amateur with woodworker, i typically feel overpowered with the entire arrangement kzbin.infoUgkxrYREG3-7f1Aqk9ams3ZESRNzGnfdUtyQ . 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!

[@tonymeggait704]

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

[@brandoncoyle7110]

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.

[@user-vp1sc7tt4m]

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!

[@ellenhal1537]

I bought this as a gift for my friend kzbin.infoUgkxcZqgZ8Ynkiz5n_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.

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 :) :)

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.

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..

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?🙏

[@elcam84]

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.

[@morrishowell7410]

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.

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.

[@jrc6158]

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 😂.

Great show Matt! Question... I have two temperature controlled chicken coops. Well as controlled as they can be uninsulated. You mentioned rockwool is sound (we got a couple roo's), mold, and bug resistant. Any thoughts about how well this would work for this application in regards to all concerns listed above? Seems like I wouldn't have to run two 8000btu A\C's ( that have issues keeping up in the summer) constantly, or 15 - 250watt heat lamps during the coldest January winters (that struggle to keep the temp at 68 to 74 when it's below zero). The coops are pretty tightly built with weather proofing with air exchange fans, and everything is automated. I would just love to see my heat/A/C's work less often, keep the noise of the Roo's down for my neighbors, not have the structure rot from any water that's absorbed by insulation, not give a new home to bugs or rodents.... Seems like I'd save more money in the long run, and I'd cover the walls with thin ply wood and maybe tape the seems. ( I'm not worried about the floor rotting, that has a moister barrier on the bottom, and a large pond liner on the inside and is cover in wood chips for bedding and insulation). Thanks for any thoughts in advance. (P.s. to anyone with concerns about the use of heat lamps or a/c's.... I am a long time farmer, the insurance company, Fire Marshal, and animal control all approve of our set up....please don't judge.

I wish I had known about rock wool several years ago. My parents had an addition done and they wanted insulation put in between the first and second floor for sound dampening. Unfortunately the contractor used normal insulation so it did nothing for sound.

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

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.

The face of Rockwool!

[@ralphsully5659]

Thanks Matt huge fan of yours just looking for some insight on roxul vs spray foam ...I’m in the northeast region and am currently finishing my below grade basement .... we have three windows in the space for ventilation and no moisture issues and was thinking on closed cell spray foam directly against my poured concrete foundation but for the ceiling was wondering if you would do a) closed cell b) open cell or c ) Roxul

Great video as always Matt. Is it safe to assume the r value for safe n sound is roughly the same as the comfort batt?

[@stephenguymcgrath]

No.

[@doomaster4]

Closer to the r15 just a little more dense. Same dimensions as the r15 and r30 is just 2 of the r15 but molded as 1 piece.

Hi Matt. What are the current thoughts on comfort board under a 12/12 pitched metal roof?

[@terrymashburn5073]

Hi Matt love your content. You mentioned that that there was a 2012 IBC code for the fire safety of the floor system. I am having trouble finding the code. Is it possible for you to share that code? Thanks in Advance.

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.

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?

[@timothycronin9746]

Hi Mat. Watching more daily. In this video at 4:03 into it you show a roof system with Rockwell that also looks like it is venting the roof as well. Which video would that be? I will be building a timber frame this spring in northern N.H. Looking for the best roof system to go with. Any advice on your videos would be greatly appreciated. Great videos! No wasted time ,to the point, loaded info and explained very well. Thanks Tim

[@onememories8523]

Great video ! Thank you for sharing. I have house that was built in the 50s. Do you recommend this be used an insulation in the crawlspace over foam insulation where the price is so expensive?

[@glenpearce3883]

Here in Manitoba the “floor” of the crawl space needs drainage and a vapour barrier. The walls require a interior vapour so refits frequently use closed cell foam either boards or sprayed on. I’m sure this is not required in warm southern states. There isn’t a blanket best practice for everywhere. The best advice will come from your local building contractors and inspectors.

Ya I'm going to foam spray in my apartment soundgood

[@Squat5000]

If you are using rockwool, at the full cavity depth, can you skip fire blocking? I see that there was no blocking added in your walls other than where necessary for OSB attachment. That would be a fantastic reason to use it in my area!

[@thanhthai8544]

What can I use for insulation for my preexisting shed to prevent condensation and mold? I want to put in mini wood stove.

[@sauce_aux]

Rockwool for acoustic projects, all day!!!

hi matt i was wondering if I can use the rockwool comfortboard on the outside of a all block house walls?? I am currently biulding this house, I am looking for the best way to keep the south tx heat out

[@erikolmsted3129]

Hey Build Show, love the emphasis on exterior insulation. It makes so much sense. I was wondering if you could share how you handle inswing exterior doors when using deep exterior insulation. In my experience as a building material supplier, door manufacturers are limited in the depth of sill that can be offered on inswing doors. Particularly with 2x6 wall construction and 2" of exterior insulation. Required jamb/sill depths would require 8-9/16" or greater to allow for 180 degree swing of an inswing door. Have you had any challenges that with this? How would you detail these door sills?

[@an7h0ny88]

We install doors in the middle of the assembly. Remove the brickmould or order with a flange and attach to the framing as you normally would, sealing it to the WRB. Insulate up to and around the door. Flash the 2" of exterior insulation with a membrane and bent metal of some sort, or wood, or whatever.
