Weather cooled so back to my most miserable project. 2.5 hours in the attic removing collapsed fiberglass, air sealing, and laying rockwool. I'm up to about 60 sq ft at full air seal plus r60 insulation now. More area has just r30 but isn't big enough for the second layer yet. Low crawling back and forth for every bat working alone is slow as fuck.

Found this. Something tells me that isn't insulation contact rated but what do I know. I forgot to take an after pic of the installed and air sealed tenmat hat that is there now.
