Is this insulation Safe to use

[yinpin]

Good Morning,
My wife decided that she wanted to white wash the hearth last week so I took apart the HI200 front covering to prep for paint. I got to thinking...I have a pile of insulation in the basement that came with a batch that I got from a construction buddy when I re-did a wall down there this spring. I wanted to add some insulation above the insert since it there is only a thin bit of insulation up there now. Can this insulation be used for that safely?

Roxul aka rock wool is the kind you would want for that application. Fiberglass is not ok for that. If what you have there is unknown type, I wouldn’t use it.

That doesn't look like rock wool to me. I wouldn't use it

Thanks for the feedback. I will get this stuff in the attic above the garage and find a small amount of Rock Wool. Hate to have to buy a lot but we will see.

It looks like Selkirks universal shielding insulation, which is made for this. Can you get in touch with your construction buddy to see if he knows? https://www.lowes.com/pd/SuperVent-...zk9iGkdbIfgs3uBeGzBoCLCYQAvD_BwE&gclsrc=aw.ds

Looks like fiberglass to me.


In addition to rock wool, kaowool would also be appropriate.
