How Long Does Spray Foam Insulation Last? – The lifespan of spray foam insulation can vary depending on factors such as the type of foam used, the installation quality, and the conditions in which it is exposed. Generally, spray foam insulation is designed to last for the lifetime of the building in which it is installed, which is typically around 80 years to 100 years or more.
Closed-cell spray foam insulation tends to be more durable than open-cell foam, as it has a denser structure and is less susceptible to moisture damage, mold, and degradation. However, even closed-cell foam can be affected by long-term exposure to moisture or other environmental factors that can impact its performance over time.
To ensure that spray foam insulation lasts as long as possible, it’s important to have it installed by a qualified professional who can ensure that the insulation is applied correctly and to the manufacturer’s specifications. Proper ventilation and moisture management can also help extend the life of spray foam insulation and prevent issues such as mold growth or deterioration. Regular inspections and maintenance can help identify and address any issues that may arise over time, and can help ensure that the insulation continues to provide optimal performance for many years to come.
