Mold Resistant

The Benefits of Nu-Wool's EPA Registered Fungicide

All Nu-Wool insulation products are made with a boron-based, EPA Registered Fungicide, which makes the insulation resistant to mold. Under federal law, claims of mold resistance can only be made by products that contain a fungicide registered with the EPA for use in that product. Virtually no other insulation products contain such additives.

Moisture Management Nu-Wool Premium Cellulose Insulation spreads it out and dries it out

Mold can grow on many materials commonly found in a building. The key to controlling mold growth is to control the level of moisture in a building. The superior moisture management properties of Nu-Wool Premium Cellulose Insulation actually make it a better choice than fiberglass insulation for managing moisture problems. Nu-Wool Insulation absorbs moisture, redistributes it and lets a wall dry in a controlled manner. If moisture gets into a wall insulated with Nu-Wool Premium Cellulose Insulation, the likelihood of the insulation remaining wet is far less than with fiberglass insulation.
