Blown-In Fiberglass Insulation vs Cellulose: Which is Better for Your Home?

When considering insulation for your home, two popular options often come into focus: blown-in fiberglass insulation vs cellulose insulation. Both are effective, but they come with distinct characteristics that may suit different needs. Let’s break down the pros and cons of each to help you make an informed decision.


A side-by-side comparison of blown-in fiberglass insulation and cellulose insulation being installed in an attic.

Advantages of Blown-In Fiberglass Insulation

  • Moisture Resistance: Fiberglass is naturally resistant to moisture, making it a durable option in humid environments.

  • Fire Safety: It is non-combustible, offering an added layer of safety for your home.

  • Longevity: With proper installation, fiberglass can maintain its effectiveness for decades.


Drawbacks of Blown-In Fiberglass Insulation

  • Settling Over Time: While minimal, some settling can occur, potentially reducing efficiency.

  • Installation Challenges: Requires professional expertise to ensure proper coverage without gaps.


Advantages of Cellulose Insulation

  • Eco-Friendly: Made from recycled paper treated with fire retardants, it’s a sustainable choice for environmentally-conscious homeowners.

  • High R-Value: Cellulose offers excellent thermal resistance, helping to keep your home warm in winter and cool in summer.

  • Pest Deterrence: The treatment process often includes additives that deter insects and rodents.


Drawbacks of Cellulose Insulation

  • Moisture Sensitivity: While treated for fire resistance, cellulose can absorb moisture, leading to potential issues like mold if not properly installed.

  • Dust Production: The installation process can generate significant dust, requiring appropriate safety measures.


Which Should You Choose? - Blown-In Fiberglass Insulation vs Cellulose

Your choice between Blown-In Fiberglass Insulation vs Cellulose depends on your priorities. If you’re looking for a durable, moisture-resistant solution, fiberglass might be your go-to. On the other hand, if sustainability and a higher R-value are top of mind, cellulose could be the better option.
