The potential dangers of spray foam insulation

On Behalf of | Jul 9, 2020 | Construction Litigation |

Using spray foam is one method that home builders use to insulate the interior of a house. As long as the contractors install it correctly, there should be no issues.

However, improper installation can result in various issues. These include chemical exposure and moisture problems.

Chemical exposure

According to the United States Environmental Protection Agency, in most cases chemical exposure through inhalation only occurs during the installation process. During the process, the only people that should be on the worksite are workers who are wearing the required protective equipment. The vapors then linger for a while until a thorough cleaning and ventilation of the area occurs.

Typically, there are no long-term exposure concerns because the chemicals in the foam are inactive. However, demolition and renovations, as well as grinding or heating the foam, can wake up the toxic emissions. Incorrect installation may also lead to off-gassing, which can lead to breathing problems or other health issues.

Moisture issues

According to the Boston Globe, another potential issue with spray foam insulation is excess moisture. This issue becomes even bigger if there is not proper ventilation, such as in a bathroom that does not have a fan or a big enough one for the space.

If moisture is unable to escape, this can lead to a more serious mold problem. Breathing in mold spores over a period of time can result in health issues. Excess moisture also leads to an environment that is perfect for pests of all kinds, including termites, which often cause excessive damage to the foundation of the home before anyone notices.
