When it comes to insulating your home, blown-in insulation is an excellent choice. This type of insulation is made up of loose fibers that are blown into your walls or attic. Creating a barrier that helps keep your home warm in the winter and cool in the summer. But with so many different types of blown-in insulation available. How do you know which blown-in insulation is right for your home? Let’s take a closer look.

Benefits of Blown-In Insulation

Blown-in insulation offers a range of benefits for homeowners. Here are some of the key advantages of this type of insulation:

  1. Energy efficiency: Blown-in insulation can help reduce the amount of energy needed to heat or cool your home. Resulting in lower energy bills and a smaller carbon footprint.
  2. Easy installation: Blown-in insulation is easy to install and can save you time and money on installation costs.
  3. Improved indoor comfort: Blown-in insulation acts as a barrier, regulating indoor temperatures, reducing drafts, and enhancing overall home comfort.
  4. Noise reduction: Blown-in insulation can help reduce outside noise, creating a more peaceful and quiet environment inside your home.
  5. Good coverage: Because blown-in insulation is made up of loose fibers, it can conform to even the most irregularly shaped spaces, providing excellent coverage and insulation.
  6. Moisture resistance: Some types of blown-in insulation, such as fiberglass and mineral wool, are resistant to moisture. Which can help prevent mold and mildew growth.

Overall, blown-in insulation is an excellent choice for homeowners who want an affordable, effective, and easy-to-install insulation solution that can help reduce energy bills and improve indoor comfort.

Fiberglass Blown-In Insulation: Pros and Cons

Fiberglass blown-in insulation is one of the most common types of blown-in insulation. It’s made up of tiny glass fibers that are blown into your walls or attic. One of the biggest advantages of fiberglass insulation is that it’s affordable and widely available. It’s also resistant to moisture, which can help prevent mold and mildew growth. However, fiberglass insulation can be irritating to the skin and lungs, so it’s important to wear protective gear when installing it.

Here are some pros and cons of fiberglass blown-in insulation:


  1. Energy efficient: Fiberglass blown-in insulation has high R-value, which means it is very effective at reducing heat transfer and keeping your home cool in the summer and warm in the winter.
  2. Fire-resistant: Fiberglass insulation is non-combustible and does not emit toxic gases in the event of a fire.
  3. Good coverage: Fiberglass blown-in insulation can fill even the smallest gaps and crevices in your attic or walls, providing a seamless and effective insulation barrier.
  4. Durable: Fiberglass blown-in insulation is very durable and can last for several decades without losing its insulation properties.


  1. Can be irritating: Fiberglass blown-in insulation can be irritating to the skin, eyes, and respiratory system, so proper protective gear is required during installation.
  2. Susceptible to moisture: Fiberglass blown-in insulation can become compacted and lose its insulation properties if it gets wet, so it is not recommended for use in areas that are prone to moisture.
  3. Settling: Over time, fiberglass blown-in insulation can settle and become less effective, especially if it is not installed correctly or if there is not enough insulation.
  4. May not be eco-friendly: Some types of fiberglass blown-in insulation can contain formaldehyde, a chemical that is harmful to the environment and human health, so it is important to choose a product that is free from harmful chemicals.

Cellulose Insulation: Advantages and Disadvantages

Cellulose insulation is made up of recycled paper and other plant-based materials. One of the biggest advantages of cellulose insulation is that it’s eco-friendly and made from renewable resources. It’s also an excellent insulator, providing good coverage and helping to reduce energy costs. However, cellulose insulation is more expensive than fiberglass insulation and can be a fire hazard if not properly treated with flame-retardant chemicals.

Mineral Wool Blown-In Insulation: Features and Benefits

Mineral wool blown-in insulation is made up of rock or slag wool fibers that are blown into your walls or attic. This type of insulation is known for its excellent fire resistance and soundproofing properties. It’s also resistant to moisture and pests, making it a good choice for homes in humid or insect-prone areas. However, mineral wool insulation is more expensive than other types of insulation and can be heavy and difficult to install.

Eco-Friendly Blown-In Insulation Options

If you’re looking for an eco-friendly blown-in insulation option, there are a few different materials to consider. In addition to cellulose insulation, which we already mentioned, you can also choose from materials like recycled denim, sheep’s wool, or even straw. These materials are all sustainable and renewable and can provide excellent insulation for your home.

Which Type of Blown-In Insulation Material is Right for You?

When choosing a blown-in insulation material, it’s important to consider your budget, your climate, and your personal preferences. If you’re looking for an affordable option that’s widely available, fiberglass insulation may be the way to go. If you’re concerned about the environment and want an eco-friendly option, cellulose or natural fiber insulation may be a good choice. And if you’re looking for the best possible insulation performance, mineral wool insulation may be the way to go.

Choose the Best Attic Insulation for Your Home

If you’re specifically looking for attic insulation, there are a few additional factors to consider. Attic insulation should be installed to the recommended R-value for your climate zone and should be installed with proper ventilation to prevent moisture buildup.

Additionally, if you use your attic for storage or as a living space, you may want to consider a more durable insulation material like mineral wool or natural fibers.
