Mold in Today's Homes:

Building science and construction methods have changed over the last 10-15 years.  Architects and builders now make a concerted effort to tighten-up wall design by reducing airflow, both in the design of the system and the type of insulation used.  Does that mean that today's homes are more susceptible to mold?  NO. 

Fortunately, the vast majority of molds are harmless to humans and pets.  However, certain molds can damage building structures by literally destroying wood building components through decay.

Control Moisture, Control Mold:

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

The superior moisture management properties of Nu-Wool Premium Cellulose Insulation actually make it a better choice than traditional insulation for managing moisture problems.  Nu-Wool absorbs moisture, redistributes it and lets a wall dry in a controlled manner. 

Accordingly, it is very important that walls are able to dry out when they do become wet.  Because of its excellent moisture management properties, Nu-Wool Premium Cellulose Insulation helps walls dry out faster.

Nu-Wool's Mold Protection:

Nu-Wool Premium Cellulose Insulation is one of the few insulation products that contains a mold-fighting fungicide registered by the Environmental Protection Agency.  Registration is achieved only after rigorous testing to ensure that the borate-based fungicide makes Nu-Wool Insulation resistant to the growth of mold, even when exposed th conditions favorable to mold growth.

Under federal law, a claim of mold resistance can only be made by a product registered with the EPA as a fungicide, or by a product which contains a fungicide registered with the EPA for use in that product.  Very few insulation products meet those requirements, but Nu-Wool Premium Cellulose Insulation does.


5 Things you need to know about molds

  1. Common indoor molds are penicillium and aspergillus. Gladosporium and alternaria are common outdoor molds that are brought indoors.
  2. In cold weather, molds can be found on the corners of exterior rooms.  Corner surfaces are colder than other areas and this increases the relative humidity on the interior surface of the corners.  When the relative humidity reaches 70% on the wall surface, molds can form.
  3. Reduce indoor humidity to decrease mold growth by venting bathrooms, dryers and other moisture producing sources to the outside.  Use exhaust fans whenever cooking, dishwashing or cleaning.
  4. Provent condensation: reduce the potential for condensation on cold surfaces, i.e., windows, piping, exterior walls, roofs and floors by adding insulation or raising the temperature of the condensing surface.
  5. There are over 100,000 species of molds.  People should be vigilant about places in the home they rarely inspect such as crawl spaces and plumbing access areas.  Areas of potentially higher moisture should always be inspected.
