Can Spray Foam Protect Against Mold?

No homeowner wants to deal with a mold problem. Significant mold presence can damage air quality and lead to health complications like asthma attacks and allergies. Mold can also cause unsightly wall stains and even lower your property value.


Once mold is present in a home, removal is often difficult. Scrubbing the growths with bleach proves ineffective, and even mold-specific treatment products can’t always penetrate mold that grows beneath tiles or behind wallpaper.


Generally, mold prevention is the best strategy. Mold thrives in a moist environment, and so homeowners can try dehumidifying methods to keep mold at bay. When it comes to moisture prevention, spray foam insulation may be the perfect tool.


How Does Spray Foam Prevent Mold Growth?


Unlike other types of insulation, spray foam forms an air seal when applied properly. Spray foam can adhere to almost any interior surface, and once it sets, spray foam fills gaps and becomes impervious to moisture. This means that dampness will not pass through a wall of spray foam, and will not be able to enter through an air leak. Additionally, mice and other vermin rarely eat spray foam chemicals or hardened foam, so rodents and insects won’t make holes where moisture can sneak in.


Indoor moisture can also form through condensation. When warm air touches a cold surface, water in the air changes from a gas to a liquid, coating the material with dampness. Spray foam chemicals act as a barrier so that the warm air in your home does not come into contact with the cooler surfaces near your home’s outer walls.


Additionally, spray foam protects against mold because it is more versatile than other insulation styles. Spray foam guns can squeeze spray insulation into tight nooks and crannies where other moisture-sealers can’t reach. Spray foam kits can also seal roofs, the space below floorboards, and other unusual places where mold may hide.


The Bottom Line


Spray foam insulation is moisture resistant, seals air leaks, and helps prevent condensation, making the material a perfect choice for mold prevention. As a bonus, spray foam can even reduce your heating and cooling energy use, which according to the Department of Energy, accounts for about 56% of the energy used in U.S. homes.


Stop mold before it starts, and consider installing spray foam insulation to protect your home from this harmful and ugly fungus.
