Looks like loose fill wool but I’ve never seen it here in Florida. Any ideas?
Is it ok stuff?
I was going to say but, it was upside down…
Inspectopedia says it is higher r value than fiberglass. Also less strain on the envirement to make it.
Yes, R-factor of Fiberglass batt is about 2.2-2.7 per inch and Rockwool is 3.0-3.3 per inch.
Mineral wool batts like Roxul is about 4.2 per inch.
EXPS is 5.0 per inch.
Hope this helps.
Thanks for the info.
