Rockwool is a danish company. Great to see it used worldwide.

I love Rockwool. I've used it under a Sunroom and am going to add it to my Crawlspace and Attic. The GREAT thing about it is, you don't need to wear a mask or special clothing when installing it like you do with fiberglass! Also, I've used an electric knife if needed to cut for sizing. EASY!


* Better fit, flexible edge compensates for normal frame variability, cuts easily
* Made from natural and recycled materials - user friendly, no fiberglass in product
* Easier and faster to install
* Water-resistant
* Non-combustible, fire-resistant up to 2150º F
* Excellent sound absorbency
* GREENGUARD certified; chemically inert - CFC and HCFC free product and process
* Does not promote growth of fungi or mildew
* Friction fit to ensure optimum performance, no sag over the years

You failed to highlight the fact that Rockwool will not harbor will mold and mildew after a days/ weeks exposure to moisture.

I had no idea that it's called Rockwool because it literally is rock in a different form. So cool.

Rockwool is also a great insulator for use in double walled smokers, particularly for the smoking chamber and the firebox for use in offset smoking.

I tested it for use in my forge walls and it held up surprisingly well

[martindick]

Hmm, was going to use this for a forge, but might use it in my remodel between walls for sound & fire between walls.

I would like to see LOWES carry the outside comfort board RockWool for the outside walls and not just the insulation that goes between the studs.

This is pretty cool!
I just helped install insulation yesterday for the first time which was neat.

[rizabalanca]

Thank you thank you guys I love it I'm using this on my house I'm using this in my house as we speak I'm doing the big demo appreciate you New York

Do I need to put vapour barrier before installing the drywall?

[DOMINYPAUL]

Cool, I have lived in Hawaii and I can tell you there's plenty to be had.

And what VOCS does it give off, and for how long?

Matt Rissinger has several videos about Rockwool products. He builds high end homes in Austin Texas.

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?

I so thought I'd be binge watching my soap operas this afternoon, instead bingeing on insulation videos because I'm building a tiny home and about to hopefully escape the SOAP OPERA that is my *CURRENT LIVING SITUATION* 😂😂😂😂 I think a craniotomy would be more pleasant than people-drama. So ready to be by myself. If summer wasn't so dang hot, I would just live in the bare bones structure, however, getting insulation (and drywall) will be a step in the right direction. Sorry, internet, for vomiting on you 😆

I handled tons of this stuff and the warnings on packaging back then.. are up there with asbestos

[melindaherod]

I know that. I'm asking, what is it for this insulation? The video did not address this.

[chrisyu]

so very fine inorganic asbestos? when inhaled into the lungs how does the body absorb/expel it?

[davidpatrick]

I have an old motorhome that has a tall fiberglass roof. Is there a way to glue it or tack it to the inside fiberglass so that stays in place until I get the ceiling covering.... do I need a vapor barrier and if so where and how? The vehicle is about 15 feet long.
