Jerry, Is the cardboard fire treated? Or supposed to be? I see the cardboard on occasion and have mentioned the fire potential to clients. I don’t go “overboard”, but i do mention it. I used to install insulation in new houses around 15+ yrs. ago. When it would slow down, we on the new home side would help out the retrofit division of the company. They did the blow-in insulating of existing homes. We used foam baffles with fiberglass batting stuffed under to block the soffits prior to the blow ins, at that time. This is if they (we) bothered at all. It was a pain in the a$%
to shimmy into each cavity to put that baffle in, and then stuff the insulation around each one. I have since as an inspector run into two homes done by the same company, where no baffles were installed prior to the blow ins. Two houses in particular that had to have tear offs due to rotting of the structure underneath. They required the rebuilding of large sections of the rafter framing , and with installation of new decking and re-roof. The cost was about $12,000 on one, $14,000 on the other.
