Mold and mildew can be a problem, but spray foam insulation usually doesn't cause it. However, the right combination of excess condensation and moisture, combined with cracks and voids near the foam insulation, can create the perfect environment for mold and mildew to grow. This is especially true with closed-cell spray foam, which is stiffer than other types of insulation. Mold and mildew can start to grow behind the insulation, which can go unnoticed until it becomes a major issue.
This usually happens when spray foam is not installed correctly and there is space left between the insulation and the wall, allowing moisture to enter and giving mold the perfect place to thrive. Horror stories about the moisture problems of spray foam insulation can make anyone hesitant to invest in the product, as no one wants to spend money on insulation just to make it damp and ineffective. While the moisture problems of spray foam insulation are real, they are not as common as you might think; in fact, spray foam is designed to resist moisture, providing much greater protection for your home. Some homeowners have even had to evacuate for months after installation due to the smell of spray foam from the insulation, mixed with a poor ratio.
If this is not possible, it is best to seek an appropriately qualified expert who specializes in spray foam. Aerosol foam products are tested to the same standards as other insulation measures and must be installed to appropriate standards. This can be due to a self-made installation that didn't go as planned or an error by the installers who didn't know what to look for when installing the spray foam. Lack of adequate ventilation can lead to overheating, carbon monoxide poisoning, and roof damage if spray foam insulation is used in the attic.

One of the reasons people like spray foam is because it fills in all gaps wherever it is applied. Many of the most common moisture problems in spray foam insulation occur when it is not used correctly. Aerosol foam is an established product that has been used in the United Kingdom for more than 30 years and internationally for even longer with few issues.
