Discover the Surprising Life Expectancy of Blown-In Insulation!

Blown in attic insulation is an effective and long-lasting solution for keeping your home comfortable and energy-efficient. The life expectancy of blown in insulation can vary depending on the type of material used. Here are the estimated lifespan of blown in insulation materials:
  • Cellulose insulation: 20-30 years
  • Fiberglass insulation: 30-50 years (since it is not degraded)
  • Cellulose insulation is made from recycled natural materials such as paper and cloth, and while it is an environmentally-friendly option, it may not last as long as fiberglass insulation. Fiberglass insulation is made from fine glass fibers and is known for its durability and longevity. It is important to note that proper installation and maintenance of blown in insulation can also impact its lifespan. Regular inspections and repairs can help extend the life of your insulation and ensure optimal performance. With the right care, blown in insulation can last for decades and provide long-term benefits for your home’s energy efficiency and comfort.

    Understanding Blown-in Attic Insulation

    When it comes to home insulation, blown-in attic insulation has become one of the most popular choices among homeowners. It’s a cost-effective way of insulating your home that offers a variety of benefits, including reducing energy bills, preventing air leaks, and keeping your home comfortable no matter the temperature outside. But what is the life expectancy of blown in insulation?

    The Lifespan of Cellulose Insulation

    Cellulose insulation is a type of blown-in insulation that is constructed from recycled natural materials such as paper and wood fibers. Due to its composition, it can last for a considerable amount of time, usually between 20-30 years. However, its lifespan can vary depending on several factors.

    Factors That Impact Blown-in Insulation Lifespan

    Several things can impact the lifespan of blown-in attic insulation, including:
    • Installation: Proper installation is crucial to ensuring the longevity of insulation. Poor installation can cause gaps and uneven coverage that will reduce the effectiveness of the insulation.
    • Maintenance: Maintaining your insulation by keeping it dry and free of pests will help prolong its lifespan.
    • Environmental factors: The climate in which you live can also impact how long insulation lasts. Extreme temperatures and humidity can lead to the degradation of insulation over time.

    The Lifespan of Fiberglass Insulation

    Fiberglass insulation is another type of blown-in insulation that can last longer than cellulose insulation. This is because fiberglass is not as susceptible to moisture as cellulose is. As a result, fiberglass insulation can last 30-40 years or even longer if cared for properly.

    Signs it’s Time to Replace Blown-in Attic Insulation

    There are several signs that it’s time to replace your blown-in attic insulation, including:
    • Increased energy bills: If you notice a sudden spike in your energy bills, it could be a sign that your insulation isn’t working as effectively as it should be.
    • Unusual temperatures: If your home is unusually hot or cold, it could be a sign that your insulation needs to be replaced.
    • Pest infestations: Pests such as rodents and insects can damage insulation, making it less effective at keeping your home insulated.

    Differences Between Blown-in and Other Types of Insulation

    There are several differences between blown-in insulation and other types of insulation, such as batt insulation. Blown-in insulation is typically more affordable than batt insulation, and it’s easier to install. It can also fill hard-to-reach areas, making it a more effective insulation solution overall.
