Does anyone know anything about this insulation. I’ve seen it before in remodeling projects over the years, but as an inspector I’d like to know more about it. Is it a fire hazard? Treated in any way for vermin or fire? It appears to be some sort of shreaded cellulose material. In this picture, the small amount of dark grey is a layer of rockwood, then a lighter color grey layer of regualar cellulose fiber and then the “blonde” layer of whatever it is!

It appears to be blown-in cellulose fiber insulation. There are several brands on the market. Most have a chemical fire retardant added to reduce the flame spread and smoke developed rating.

Hi guys,
Balsam wool that I have seen has been like 3 1/2" with vapor barrier
It does look like balsam (loose fill) with a "red head" layer.
