    1. You should design your building assemblies so that your insulation stays dry, if possible, no matter what type of insulation you choose.

    2. Most brands of cellulose are treated with borates, which reduce flammability, discourage insects, and may inhibit mold.

    Q. "Will cellulose typically last 20 years under normal usage conditions?"

    A. Eighty years should be no problem.
