Aerosol foam insulation has an estimated life expectancy that ranges from 80 to 100 years. And that can be achieved with little or no maintenance. The material is tough and can last as long as your building. Unlike cellulose and fiberglass, aerosol foam does not deteriorate, sag or settle. Aerosol foam insulation can last between 80 and 100 years, if applied correctly.
For most people, that could be the life of their home. The International Association of Certified Housing Inspectors states that aerosol foam insulation, adhesive tape and insulation for household wrapping can last more than 80 years. At the same time, cellulose, loose filler, foamed cardboard, loose filler and rockwool insulators can last up to 100 years. This may seem like a long time, but many homeowners neglect their property history.
Often, homeowners buy a property with old insulation. When this occurs, your estimate of the lifespan of your insulation may be overestimated. When properly installed, aerosol foam insulation lasts between 80 and 100 years. In particular, closed-cell insulation is incredibly durable because it doesn't deteriorate or show any flexibility.
These are common-sense aspects of homeownership, not special measures to be taken specifically with aerosol foam insulation. If you let spray foam insulation dry the right way and for the right amount of time, it shouldn't pose any threat to your home or your health. However, the right combination of excess condensation and moisture mixed with cracks and voids near the foam insulation can become the right combination for mold growth and fungi. One of the common spray foam insulation problems for roofs and attics occurs when the aerosol foam is not thick enough to prevent airflow from improving energy efficiency.
In addition, it is important to avoid placing open-cell insulation to avoid problems in insulating ceilings with sprayed foam, such as the formation of mold. In open areas, such as mezzanines and attics, aerosol foam insulation is ideal for sealing and insulating these spaces. However, to avoid problems with spray foam insulation in attics, you should let it cure and harden for more than 24 hours. Both types of aerosol foam insulation can last between 80 and 100 years, and closed-cell aerosol foam has a slight advantage in terms of durability.
However, if you see these problems after installing spray foam, it may be a problem with the insulation. Insulation professionals also know where spray foam should be added for maximum efficiency, as well as how much insulation should be installed. There are many types of home insulation to choose from, each of which has different benefits for homeowners. If moisture inside the roof permeates the insulation, you may experience problems and roof damage with spray foam. Insulation may need to be removed and replaced for a variety of reasons, from water damage to animal activity.
Aerosol foam, except in extreme cases such as a leaking roof, an infestation or adverse weather conditions, is less susceptible to external factors than other types of insulation. Roof leaks can cause insulation degradation over time, as mold formation can corrode the outside and inside of the insulation.
