Fire Resistance 

Cellulose insulation containing borates acts as a fire retardant. Sodium borate compounds, similar to the ones found on Nu-Wool insulation, release water from their molecular structures when they heat up during a fire. Water, of course, puts out a fire. Borate in cellulose insulation may prevent the spread of a fire in your home in case the worst possible situation happens. 

Bug and Mold Resistance 

Borate compounds can kill common bugs, including ants, cockroaches, mites, spiders, termites, and silverfish. Borates in cellulose insulation also resist mold and fungi growth. This kind of insulation can improve the overall quality of your home by preventing pests and microorganisms from taking root within your floors, walls, or ceilings. A lack of pests may prevent structural damage, improve indoor air quality, and keep your family safe.

Staying dry represents one key to the effectiveness of cellulose insulation. Borate compounds may prevent moisture build-up on insulation during times of high humidity. Sadly, if cellulose insulation gets wet due to water leaks or flooding, you’ll have to replace it as soon as possible. For everyday moisture prevention, Nu-Wool is a top-notch product.


Borate is a non-toxic substance added to cellulose insulation. It’s mined from the Earth, similar to baking soda or salt. Borate salts are added to Nu-Wool to act as a fire retardant. Techs at Valley Insulation take care when handling our blow-in insulation by wearing gloves, long sleeves, and safety glasses. Even so, cellulose insulation is relatively easy and safe to handle compared to fiberglass.
