September is “National Indoor Toxic Mold Awareness Month” and to commemorate the event, CertainTeed Corporation is encouraging homeowners to evaluate the potential for mold growth in their homes. Established by the United States Environmental Protection Agency (EPA), the purpose of Mold Awareness Month is to educate homeowners about the negative financial and health-related effects of indoor molds and toxins.
The occurrence of mold growth can be disastrous. According to the Insurance Information Institute, water and mold damage cost insurers approximately $2.5 billion annually. Mold can be prevented and treated by paying attention to the details of a home, in its design, construction and maintenance.
Mold or fungi are microscopic organisms that play a key role in the decomposition of leaves, wood and other plant debris. Although helpful in nature, the presence of mold in the home can be harmful to structural components, as well as home occupants. When excess moisture accumulates indoors, mold problem areas will develop. Depending on the sensitivity of the occupants, mold exposure can cause symptoms ranging from eye irritation, wheezing and nasal congestion, to more serious respiratory ailments. There are molds that can grow on wood, paper, carpet and food. All mold needs to grow is a wet surface and an organic food source.

According to the EPA, the only way to control indoor mold is to control moisture levels in a home. A good first place to look is the interior walls of a home, specifically the insulation and gypsum board. Fiberglass provides excellent insulating performance that does not absorb moisture.
Water can enter the home from many sources, mainly by leaking or seeping through the floors and walls. Mold- and moisture-resistant gypsum board is another building material that can help fortify a wall assembly’s defense against mold.
