Blown-In vs. Batt Insulation: Pros, Cons, and Best Uses for Your Attic
Expert Advice from Good’s Roofing, Your Trusted Insulation Installation Team in Michigan
Your attic insulation plays a major role in keeping your Michigan home comfortable and energy-efficient year-round. But with so many insulation options, it’s easy to feel overwhelmed, especially when trying to choose between two of the most common types: blown-in insulation and batt insulation.
At Good’s Roofing, we specialize in blown-in insulation installation because we believe it offers the best long-term performance for Michigan homeowners. Still, let’s break down the pros and cons of each option so you can make an informed decision that fits your home’s needs.
What Is Batt Insulation?
Batt insulation—often called “blanket insulation”—comes in pre-cut fiberglass rolls or sheets. It’s one of the oldest and most recognizable forms of insulation and is typically installed between joists, studs, or rafters.
Pros of Batt Insulation:
- Easy to install in open spaces like new construction or unfinished attics
- Lower upfront material costs
- Readily available at most hardware stores
Cons of Batt Insulation:
- Hard to fit around obstructions like pipes, wiring, or tight corners
- Gaps and compression reduce its effectiveness
- Prone to moisture issues, which can lead to mold or mildew
- Less effective in older homes with uneven or irregular attic spaces
While batt insulation can work well in some situations, it often struggles to provide a full seal—especially in Michigan homes with older, less uniform attic structures.
What Is Blown-In Insulation?
Blown-in insulation, also known as loose-fill insulation, consists of small particles—usually fiberglass or cellulose—that are blown into attic spaces using a specialized machine. The result is a fluffy, even layer that fills gaps and covers hard-to-reach places.
At Good’s Roofing, we exclusively install blown-in fiberglass insulation because of its efficiency, performance, and reliability in Michigan’s demanding climate.
Pros of Blown-In Insulation:
- Excellent coverage: Fills every nook, cranny, and awkward space
- High R-value per inch, offering better thermal resistance
- Quick and clean installation with minimal disruption
- Moisture and fire resistant (especially fiberglass)
- Ideal for upgrading existing insulation in older homes
- Energy-efficient: Helps lower heating and cooling bills
Cons of Blown-In Insulation:
- Requires professional equipment for proper installation
- Not ideal for open wall cavities (better suited for attics or enclosed spaces)
Blown-In vs. Batt: Which Is Better for Your Attic?
If you’re building a new home with wide-open wall cavities and minimal obstructions, batt insulation may seem like a cost-effective option. However, for most Michigan homeowners—especially those with older homes or unique attic layouts—blown-in insulation is the better choice.
Blown-in insulation provides superior coverage, easily filling gaps, corners, and irregular spaces that batt insulation often misses. It offers a higher R-value per inch, meaning better thermal resistance and improved energy efficiency. Blown-in fiberglass is also moisture-resistant and retains its insulating properties longer without settling or degrading.
On the other hand, batt insulation can be difficult to install in tight or uneven areas. It often leaves small gaps where air can leak through, decreasing its overall effectiveness. It’s also more susceptible to moisture buildup, which can lead to mold or damage over time.
For retrofit insulation projects, especially in attics with obstructions, pipes, or older framing, blown-in insulation is ideal. It’s quicker to install, provides more complete coverage, and helps reduce heating and cooling costs year-round—something every Michigan homeowner can appreciate.
Why Michigan Homeowners Choose Blown-In Insulation
Michigan homes face intense temperature swings—icy winters, humid summers, and everything in between. Blown-in insulation adapts better to these conditions, helping maintain a consistent indoor temperature and reduce strain on your HVAC system.
Plus, with rising energy costs, an investment in proper insulation installation can lead to significant long-term savings on your utility bills.
