Which Blown-In Insulation Is Best for Attics?

If you own a home or commercial building in Nevada, choosing the right attic insulation is key to keeping your space comfortable year-round and minimizing energy bills. Blown-in insulation offers several benefits, but deciding which type is best for your attic can depend on multiple factors—from the type of structure to the local climate in places like Sparks, Elko, or Winnemucca. In this guide, we’ll explore the various types of blown-in insulation for attics, helping you make an informed decision that works for your needs.

Why Blown-In Insulation?

Blown-in insulation is often used in attics due to its versatility and effectiveness in sealing gaps and preventing heat transfer. Unlike batt or foam board insulation, blown-in insulation can reach tight spaces, ensuring a complete thermal seal. This matters because proper insulation plays a significant role in reducing your heating and cooling expenses and enhancing overall comfort.

Types of Blown-In Insulation for Attics

When considering blown-in insulation for your attic, there are three primary types to choose from:

  • Cellulose Blown-In Insulation
  • Fiberglass Blown-In Insulation
  • Mineral Wool (Rock Wool) Blown-In Insulation

Let’s break down the pros, cons, and appropriate use cases for each type.

1. Cellulose Blown-In Insulation

What It Is: Made primarily from recycled paper products, cellulose insulation is an environmentally friendly option that works well in a variety of settings. The material is treated with non-toxic chemicals to provide resistance to fire, mold, and pests.

Pros:

  • Excellent Air Sealing: Cellulose settles more densely than other materials, which helps to fill cracks and voids effectively, preventing unwanted air leakage.
  • Environmentally Friendly: Since it’s made from 85% recycled paper, cellulose is one of the more sustainable insulation options available.
  • Fire Resistance: The added fire retardants help enhance safety, a critical factor when insulating an attic.

Cons:

  • Moisture Sensitivity: Cellulose is not waterproof, and excess moisture can lead to settling and reduced efficiency over time. For attics prone to humidity or leaks, this can be a disadvantage.
  • Heavier Material: Due to its density, cellulose might not be suitable for all attics without structural evaluation to ensure the ceiling can handle the additional weight.

Best Use Case: If you’re looking for an eco-friendly, dense, and effective insulation for attics in relatively dry climates, cellulose is a strong choice.

2. Fiberglass Blown-In Insulation

What It Is: Fiberglass insulation is made from small, spun fibers of glass. It’s one of the most common types of attic insulation and can be installed as batts or blown-in.

Pros:

  • Moisture Resistance: Unlike cellulose, fiberglass does not absorb water, making it a better option for environments with fluctuating humidity.
  • Lightweight: Fiberglass is easier to install without worrying about excessive weight on the attic floor.
  • Non-Flammable: As a non-combustible material, fiberglass can help enhance attic safety.

Cons:

  • Lower Air Sealing Capability: Fiberglass doesn’t settle as densely as cellulose, so it may not seal cracks as effectively. Small gaps may remain, potentially reducing the insulation’s efficiency.
  • Potential Irritation: The tiny glass fibers can cause skin and respiratory irritation, requiring appropriate handling during installation.

Best Use Case: Fiberglass insulation works well for attics with moderate temperature swings and lower moisture risks. It’s a good balance between affordability and performance.

3. Mineral Wool (Rock Wool) Blown-In Insulation

What It Is: Mineral wool, often called rock wool, is made from volcanic rock and recycled steel. It offers several unique advantages, particularly in terms of safety.

Pros:

  • Excellent Fire Resistance: Mineral wool is highly resistant to fire, often rated to withstand temperatures of up to 1,800°F.
  • Soundproofing: It provides better soundproofing compared to fiberglass and cellulose, making it an ideal choice for attics above noisy environments.
  • Moisture Resistance: Like fiberglass, rock wool doesn’t retain moisture, reducing the risk of mold growth.

Cons:

  • Higher Cost: Rock wool is generally more expensive than other types of blown-in insulation.
  • Limited Availability: Depending on your location, sourcing mineral wool might be more challenging.

Best Use Case: If you have concerns about fire safety or need superior soundproofing, mineral wool is a worthwhile investment, particularly in areas like Sparks or Elko, where fire prevention is a priority.

Factors to Consider When Choosing Blown-In Insulation

1. R-Value

The R-value measures insulation’s resistance to heat flow. The higher the R-value, the better the insulation performance. Nevada’s hot summers and cold winters call for higher R-values, especially in attic spaces where heat loss and gain can significantly impact energy use. Cellulose, fiberglass, and mineral wool all have different R-values per inch, typically ranging from R-3.2 to R-4.2 per inch.

2. Moisture Levels

If your attic is prone to moisture or leaks, opt for moisture-resistant materials like fiberglass or mineral wool over cellulose. In areas such as Eureka or Winnemucca, where weather fluctuations may occur, this could be a critical factor.

3. Budget

Cellulose tends to be the most affordable option, while mineral wool can be more costly due to its additional benefits. A balance between cost and performance should guide your decision. Weigh the long-term savings you might achieve with a more efficient insulator against the upfront costs.

4. Fire Safety

With Nevada’s climate being dry and fire risks being a concern, fire resistance is essential. Mineral wool is naturally fire-resistant, making it a smart choice if fire safety is a top priority. Fiberglass also provides good fire resistance without additives.

Blown-In Insulation Installation Process

1. Inspection: Before insulation, it’s important to inspect the attic for potential issues such as roof leaks, ventilation problems, or existing insulation that may need removal.

2. Air Sealing: Sealing gaps and holes in the attic is crucial before installation. This prevents air leakage and ensures the new insulation performs as effectively as possible.

3. Blowing in Insulation: Specialized equipment is used to blow insulation into the attic. The insulation is applied uniformly to ensure proper coverage, without leaving any significant gaps.

4. Post-Installation Inspection: After installation, a final inspection ensures even distribution and adequate coverage.

Professional Vs. DIY: Should You Install Blown-In Insulation Yourself?

While some homeowners consider DIY installation to save costs, hiring a professional like Nevada Urethane has significant advantages:

  • Proper Equipment: Professionals use specialized blowing machines for even and effective coverage.
  • Safety Measures: Installation of blown-in insulation requires safety precautions, especially with fiberglass. Professionals have the appropriate gear to handle these materials safely.
  • Experience and Expertise: Improper installation can lead to uneven coverage, which reduces the insulation’s effectiveness. Our experienced technicians ensure your attic is fully insulated to maximize energy savings.
