Cellulose is different from fiberglass. Cellulose, a wood product (actually a long chain sugar) has lots of air pockets in it. It is these air pockets that provide resistance to heat flow and not the physical product itself.
Thus, dense pack cellulose is completely different from densely packet fiberglass.
Easy to misunderstand.
