TruSoft Cellulose is exclusively used and distributed by Dr. Energy Saver dealers. It comes with a stabilizer to reduce dusting and is trusted by our dealers as the best, most effective cellulose out there. Like TruSoft, other cellulose is also made 85% out of recycled content, with the other 15% being liquid boric acid, which helps make this cellulose flame resistant, mold/mildew resistant, and rodent resistant. Cellulose altogether is an environmentally friendly insulation option that keeps the most air leakage out with its density.
