How Long Does Insulation Last

The lifespan of insulation materials can vary depending on several factors, including the type of insulation, its quality, and the conditions it's exposed to. Here's a general guideline for the longevity of common types of insulation:

Fiberglass Insulation

Fiberglass insulation is a popular choice and can last for several decades, often up to 30-40 years or more, if properly installed and maintained. Over time, it may settle or compress slightly, which can reduce its effectiveness.

Cellulose Insulation

Cellulose insulation, made from recycled paper products, can last a long time when kept dry and free from pests. With good maintenance, it can last 20-30 years or more.

Spray Foam Insulation

Spray foam insulation is known for its durability. It can last for the life of a building when properly applied. However, its effectiveness can decrease if it's damaged or exposed to excessive moisture.

Polyurethane Foam Board Insulation

Polyurethane foam board insulation is also quite durable and can last for several decades or even longer.

Mineral Wool (Rock Wool) Insulation

Mineral wool insulation is highly durable and can last for 50 years or more if not exposed to excessive moisture.

Reflective Foil Insulation

Reflective foil insulation is often used in attics and radiant barriers. It can last a long time if not damaged and is usually considered to have a lifespan of 20-25 years or more.

It's important to note that insulation can degrade over time due to factors like moisture infiltration, pests, settling, or damage. Regular inspections and maintenance can help extend the lifespan of your insulation. Additionally, if your insulation becomes damaged or compromised, it may need to be replaced to maintain its effectiveness.

Keep in mind that these are general estimates, and the actual lifespan of insulation can vary based on local climate conditions, the quality of installation, and other specific factors in your environment. If you're unsure about the condition of your insulation or whether it needs replacement, it's a good idea to consult with a professional insulation contractor for an assessment.
