The wildfires in Southern California left my house standing but the attic
insulation was covered with soot and ashes.

about 3200 sqft. My old insulation is R-19, but Code requires an upgrade to
What is the state of the art with regard to insulation? Fiberglass in rolls
or battens, or cellulose, blown in, or what?? I heard that cellulose has a

Thanks for all input.
