Preventing Mold With Foam

Once mold spray foam insulation have found their way into your house they will grow and thrive in the warm, moist environment inside. In addition to making your house smell and look awful, mold spores can be a serious health risk for those who have asthma or other respiratory conditions. Removing and preventing the spread of mold is not an easy task, especially when the problem is hidden behind walls or in crawl spaces.

While spray foam insulation is not a source of food for mold and mildew, the results depend on how well the entire building envelope assembly manages moisture. Foam insulation, when properly installed and used with vapor retarders and air sealing products, will eliminate the moisture movement within wall cavities and studs that allows moisture to condense on cold surfaces, thus reducing the potential for structural damage and fungal growth.

Closed-Cell vs. Open-Cell Foam: Strength, Benefits, and Best Uses

In attics, spray foam insulation can be especially effective for preventing mold. The spray foam creates a sealed, airtight space that prevents moisture from getting into the attic and starving mold spores of their food source. It is also highly effective against heat loss in attics, allowing for the proper ventilation of warm air to escape the attic and cool air to enter, thereby eliminating the potential for condensation that leads to mold growth.

Another good place to use spray foam for mold prevention is in basements and crawl spaces. When applied to concrete block basement walls, rigid foam creates a thermal boundary for the home, keeping everything on the outside side of the wall in contact with the damp soil and nothing on the inside. This stops the flow of water vapor from causing condensation and mold to form on the concrete blocks and prevents it from entering the house, improving overall indoor air quality.
