Are you considering mineral wool insulation for an upcoming project?

[giseliapereira]

Did you say that Mineral Insulation contains small amounts of asbestos? It has been recommended on my building plans and I want to make sure about the asbestos.

No seeing an mention of a vapor barrier on exterior walls in a bathroom remodel project? Is it not needed for the ROXUL product? Thanks

[rickmatz]

Mineral wool is the best. Cool video. Stay away from spray foam and it unscrupulous installers. With the exception of certain applications and honest installation experts.

Great video sir! I'm going to use the R30 Rockwool attic insulation batts. Would I just need an N95 mask when installing it, or something better?

Hi! Would it be safe to use it for acoustic panels in a home studiio? usually the panels get covered with cloth to prevent any particles inhalation. Thanks!

Do you need a vapor barrier, especially on the warm side of the wall?

Can you install it over 2” of closed cell foam without having moisture or other issues?

Would Rockwool be a safe material for between studs in a T1-11 built shed, and then covered with sheet-rock? I'm worried about not noticing moisture damage over time.

I want to insulate to gable ends in the attic with Rockwool R-22 insulation. There are no vertical studs except the flat studs of the roof truss. also the are a lot of framing & siding nails which can't be cut to put new 2X6 studs. I live in Wilmington, NC & my attic get get up to around 120 degrees in the summer time & about 30 degrees in the winter. My question is: can I use a little construction adhesive to help hold the insulation in place?

Where can I buy this? Home depot is out

It was interesting to learn that mineral wool insulation contains as much as 90% recycled content.

Can I use it under a new metal roof installation over the existing mobile home tin roof? Basically, between the 2 roofs for temperature control.
This old trailer tin roof has been sweating on the under side, which is causing condensation that then drops onto my ceiling insulation, which creates mold in my ceiling panels & ruining my ceiling. I have a panel that is close to falling in from moisture damage.
I don't know exactly how to handle this. I'm thinking a new roof with insulation under it may keep the hot & cold from colliding on my tin roof & causing condensation.
Does anyone have any suggestions?

How about you discuss the 3 methods of heat transfer and how that is WAY MORE IMPORTANT than R value! This insulation will stop convection heat transfer because mineral wool blocks 100% moisture and air, unlike stupid fiberglass. (I mean, how are we in 2021 and still considering fiberglass as a form of insulation?!!!) You don't have to worry about condensation like you do with fiberglass causing moisture inside your walls. My advice, stop worrying about R value and start thinking about the 3 methods of heat transfer because that will have more of an impact on the thermal envelope of your home. Oh and STOP buying fiberglass insulation! IT'S NOT INSULATION!!!!

Can mineral wool (rockwool) be used to insulate an outdoor pizza oven?

[DavidDouglasZach]

Hello Rise. I was wandering if you could answer my question pretty please. I live in Des Moines, Iowa. Aka cold winters and hot/ humid summers. I am going to have my siding AND old crappy sheathing removed on my house (due to a hail storm). Can I install mineral wool in my 2 x 4 stud bays and NOT have to worry about adding a vapor varrier??? Mineral wool does not come with a vapor barrier attackes like fiberglass insulation does.... am I correct in understanding that RockWool doesn't require a vapor barrier even in cold climates??? Thank you for any feedback?

[ChesneyDigital]

What about wool blown in insulation? Rockwool website shows a granulated “loose fill” product but I cannot find this anywhere. Anyone know where you can buy loose fill Rockwool for blown insulation? Do you just rent a machine from Lowe’s or Home Depot and blow the stuff in existing walls or would that require a special blowing machine? I can’t find any info online about Rockwool blown insulation- I have a home that is over 100 years old and all of the existing insulation has now turned to dust- there is literally NO insulation in any of the walls anymore. Plus my home is in an urban area surrounded by low IQ thugs blasting bass so I’d like as much sound dampening as possible. Any recommendations?

Hello! Thanks for the video! Is there anything I can do to protect my health from VOC's now that the mineral wool with no green guard certificate is installed in my house? Will the VOC's trespass the walls? Thank you
