Difference Between Loose Fill Fiberglass Insulation and Cellulose

Introduction to Loose Fill Fiberglass Insulation

Loose-fill fiberglass insulation is a popular and cost-effective choice for insulating attics, basements, and ceilings. Made up of countless tiny strands of fiberglass, this insulation is blown into spaces using a hose. The jagged edges of each fiber “lock” together when the insulation settles, creating tiny air pockets that help slow the movement of heat. This process gives the material its R-value, which measures the insulation’s ability to resist heat transfer. Fiberglass is fire-resistant and, when installed properly, provides long-lasting thermal protection. It is easy to handle, and the installation process is straightforward, making it a favorite among homeowners and contractors alike.

Introduction to Cellulose Insulation

Cellulose insulation is made from recycled paper that has been treated with fire retardants. It is commonly used in attics and wall cavities, where it is densely packed between joists to prevent heat loss. Cellulose is typically installed using a blowing machine and can be a more eco-friendly option due to its recycled content. Like fiberglass, it also slows down the movement of air, but it tends to absorb moisture, which can reduce its effectiveness over time if not properly maintained. While cellulose has a high R-value, it requires additional equipment, such as a water jacket for moistening the material, and skilled installers to ensure its optimal performance.

Key Differences Between Loose Fill Fiberglass Insulation and Cellulose

The primary difference between loose-fill fiberglass and cellulose insulation lies in their composition and installation requirements.

  • Composition: Loose-fill fiberglass insulation is made of glass fibers, while cellulose is made from recycled paper. This makes fiberglass a non-combustible and more moisture-resistant option, whereas cellulose is more prone to absorbing moisture, potentially compromising its effectiveness.
  • Installation: Loose-fill fiberglass is easy to install, requiring only a blower and hose to fill the space with insulation. In contrast, cellulose insulation requires additional equipment, such as a water jacket, to ensure the material is moist enough to pack into spaces efficiently.
  • R-value: Both materials have similar R-values, but cellulose typically needs to be installed at a greater depth to achieve the same insulating effect as fiberglass, meaning it can require more material and time to install.

Advantages of Loose Fill Fiberglass Insulation Over Cellulose

Loose-fill fiberglass insulation has several advantages over cellulose, making it a more practical choice for many homeowners:

  • Easier Installation: Unlike cellulose, which requires additional equipment and careful monitoring (like the use of a water jacket), fiberglass can be simply poured into a hopper and blown into place. This makes the installation process quicker and easier, saving both time and labor costs.
  • Less Mess: Cellulose insulation is often associated with dust, especially during installation, which can be an inconvenience to both contractors and homeowners. While fiberglass insulation can create some dust, it is generally less of an issue during installation, leading to a cleaner, more efficient process.
  • More Efficient Coverage: Loose-fill fiberglass requires less material to achieve the same R-value as cellulose, making it easier to transport and reducing installation time.
  • Moisture Resistance: Fiberglass insulation is more resistant to moisture, which means it won’t lose its insulating properties if exposed to damp conditions, unlike cellulose, which can absorb water and become less effective.

While both types of insulation have their merits, loose-fill fiberglass insulation tends to be a more straightforward, cost-effective, and efficient solution for many insulation needs.

Loose-fill insulation is typically installed using a blower machine, which ensures an even distribution and proper depth, maximizing its insulating effectiveness. Hand application may result in uneven coverage, air gaps, or insufficient thickness, reducing the R-value and insulation efficiency. Moreover, loose-fill fiberglass can irritate the skin, eyes, and lungs, so it’s important to wear proper protective equipment, such as gloves, goggles, and a mask, even when applying it by hand. For best results and safety, professional installation with specialized equipment is advised.

Does blown-in fiberglass insulation settle?

Yes, blown-in fiberglass insulation can settle over time, especially if it is not installed at a proper density or if it is exposed to moisture. As it settles, the insulating value (R-value) can decrease because the insulation becomes compressed, reducing the amount of air trapped between the fibers. This results in a less effective thermal barrier. Proper installation techniques and ensuring adequate depth at the time of installation can help minimize settling. Some types of loose-fill fiberglass may settle more than others, so it’s important to follow manufacturer guidelines and periodically check the insulation to ensure it maintains its R-value.

Does fiberglass insulation deteriorate over time?

Fiberglass insulation is generally resistant to deterioration over time, provided it is not exposed to moisture or physical damage. Unlike some other materials, fiberglass doesn’t support mold growth and doesn’t degrade in the same way that organic insulations (like cellulose) might. However, fiberglass can lose its insulating effectiveness if it gets wet, as it can absorb moisture, which causes it to compress and lose its R-value. In extreme cases, wet fiberglass insulation may need to be replaced. The fiberglass material itself remains stable for many decades as long as it is kept dry and well-maintained. Regular inspections are advisable to ensure it hasn’t settled or been compromised.

How many inches of blown-in insulation is R-38?

To achieve an R-38 rating with blown-in fiberglass insulation, you typically need about 12 to 14 inches of material, depending on the specific density and manufacturer guidelines. Blown-in fiberglass insulation generally provides an R-value of around R-2.2 to R-2.7 per inch. To reach an R-38 rating, you must ensure that the thickness of the insulation is evenly distributed and the insulation is properly installed to avoid gaps or settling. The exact thickness can vary depending on factors like the type of insulation used, so it’s always best to consult with the manufacturer’s recommendations or a professional installer.

What is considered a good R-value for insulation?

A good R-value for insulation depends on the climate and the area being insulated. Generally, for attics, an R-value of R-30 to R-60 is recommended for optimal energy efficiency. For walls, an R-value of R-13 to R-21 is typical, depending on local climate conditions. The higher the R-value, the better the insulation’s ability to resist heat transfer. In colder climates, a higher R-value is necessary to retain heat, while in warmer climates, moderate insulation may suffice. It’s also important to consider other factors, such as air sealing and moisture control, in achieving optimal energy efficiency.

Why not to use fiberglass insulation?

There are several reasons why some people might choose not to use fiberglass insulation. One significant drawback is the potential health risks: fiberglass particles can irritate the skin, eyes, and respiratory system during installation or if disturbed later. If not properly installed, fiberglass can also settle over time, reducing its R-value and effectiveness. Additionally, fiberglass insulation doesn’t perform well in areas with high moisture levels, as it can absorb water and lose its insulating properties. It’s also more prone to damage from pests, particularly rodents, which can chew through it. While it’s generally non-combustible, fiberglass insulation may still not be the best choice in certain building situations. Alternatives like spray foam or cellulose might be better suited for specific applications.
