Apparently they make fibreglass insulation so it dissolves in your lungs now. The older pink stuff was chemically stable and would just stay in there forever and (allegedly) give you mesothelioma. Interesting stuff.

Belinda Carr has a spectacular Youtube channel where she goes over all this stuff. There are a ton of different building products reviewed with no BS and she doesn't pull any punches.

It would be an interesting conversation that convinces me of the solubility of glass fibers.

Regular glass as we know it (soda-lime glass) has additives so it won't dissolve in water. Soda-lime glass has lime added for that very reason. Soda glass will literally dissolve in water.

Whereas pure silica has excellent resistance to thermal shock, being able to survive immersion in water while red hot, its high melting temperature (1723 °C) and viscosity make it difficult to work with. Other substances are therefore added to simplify processing. One is the "soda", or sodium carbonate (Na2CO3), which lowers the glass-transition temperature. However, the soda makes the glass water-soluble, which is usually undesirable. To provide for better chemical durability, the "lime" is also added.

Apparently fibreglass insulation now also has other additives such as calcium to make it more soluble.

A 1998 study using rats found that the biopersistence of synthetic fibers after one year was 0.04–13%, but 27% for amosite asbestos. Fibers that persisted longer were found to be more carcinogenic.

Am I convinced? Not really. But I'll admit that I'm half-way convinced. But the fibreglass industry was peeved off enough at Belinda Carr's first fibreglass insulation video (where she had suggested health implications) that they contacted her directly and she made a follow-up video. Am I going to snort a line of fibreglass insulation? Nope. Am I still going to wear an N95 mask? Probably. Do I feel slightly safer around the stuff? Yes.

I understand the Soda part. Not that stupid!

I use Rockwool. For a few of the reasons that she mentions. And masks are a good idea. I admit to not using them very much as a young man. Defionitely do now.

Owens Corning definitely makes rigid Fiberglass panels as does Rockwool.

I liked her presentation methods. Concise and to the point.

Oh and she's cute to! Gotta dream sometimes

I dunno. I didn't know that. I guess I am that stupid.

Right there with ya. Rockwool is a spectacular product. I did my basement with Rockwool. It's a toss up between Roxul and blown-in cellulose for my favourite insulation. I like that cellulose has boron salts so you can add fireproofing, convince the rodents to move out, and insulate a building space all in one shot.

hey this smart gal is single , didnt see any rings on her fingers,,!!!! pm me anytime belinda..

Ev-en-tually (taken too long already) this ceiling will be drywalled. Very next project will blow-in as much rockwool possible, figuratively speaking. Pitch height gives plenyty of room, over 11', at 4:12 eaves too shallow to crawl in and lay blankets. Using 10 hollow core doors that will be 'attic' access panels, they'll get blanket material.
No conceivable reason for anyone up there again.
Would like to utilize some of that, but we get some real cold periods. Not Arctic Circle grade, but...

Rockwool has to lowest R-Factor of any blown in material

Mineral wool is made from slag, fiber glass is made from sand. The products contain a none detreating fiber witch will cause fibroses and one can die. the fibers are just as dangerous as asbestos. About 25 years ago the was no warning on the package now there is. A good quality mask is strongly recommended
