Is Closed-Cell Spray Foam Insulation Permanent?

Yes, closed cell spray foam insulation is a premium insulation that is considered to be a safe permanent insulation solution. However, it is important to note that no insulation is truly permanent. Over time, the spray foam insulation may break down or degrade, but it is still expected to last for many years, typically around 50 years. But it can last even longer if it is properly installed and maintained. Improper installation can lead to premature degradation of the spray foam insulation.

What Makes it Permanent?

To further understand why closed-cell spray foam insulation is a permanent solution, you must understand how it’s formed. Spray foam insulation is made of polyurethane, and isocyanate, and once combined it expands and hardens to form a solid foam that fills all the cracks and gaps in the insulation area. This creates an airtight seal that prevents air infiltration and moisture damage. Closed cell spray foam also has a high R-value, which means it is very effective at preventing heat loss and heat gain.

Benefits of using closed cell spray foam insulation:

• High R-value: Closed cell spray foam has a high R-value, which means it is very effective at preventing heat loss and heat gain. This can lead to significant energy savings on your heating and cooling bills.
• Airtight seal: Closed cell spray foam forms an airtight seal that prevents air infiltration and moisture damage. This can help to improve the indoor air quality of your home and prevent mold and mildew growth.
• Durability: Closed cell spray foam is a durable material that can last for many years. It is also resistant to fire, pests, and moisture.
