What Is R-Value for Attic Insulation?
If you’re hearing about “R-Value” for the first time—or wondering what it means for your attic—this guide is for you. At Restoration Roofing, we’re excited to share how R-Value factors into year-round comfort and energy savings—and why we now offer professional blow-in attic insulation for homeowners throughout Memphis, Collierville, Germantown, and nearby suburbs.
What Is R-Value?
Think of R-Value as a material’s power to resist heat transfer—higher numbers mean better insulation. It’s the standard measure used to gauge how well insulation keeps heat in (during winter) or out (during summer), ensuring your home maintains comfortable temperatures efficiently.
Recommended R-Values for Memphis Attics
In our climate—hot, humid summers and mild winters—experts recommend attic insulation levels between R-30 and R-60. To reach R-60, most attics need about 19–20 inches of loose-fill insulation. This range offers maximum energy savings and indoor comfort, especially for homes that use their attic as storage or face seasonal temperature swings.
Why R-Value Matters for Your Home
- Energy Savings & Lower Bills
With proper R-Value, your HVAC system doesn’t overwork to cool or heat the home—especially crucial in Memphis summers. - Consistent Comfort
No hot upstairs bedrooms or chilly corners in winter—quality insulation maintains balanced temperatures throughout your home. - Protects Your Roof and Structure
The right insulation helps maintain a balanced attic temperature, reducing moisture risks and protecting roofing materials long-term. - Environmentally Smart
Higher R-Value means less energy demand, lowering your carbon footprint—good for both your wallet and the planet.
What Is Blow-In Insulation (and Why We Offer It)
Blow-in (loose-fill) insulation is installed using a mechanical blower that evenly distributes dense insulation material—most commonly cellulose or fiberglass—across your attic floor. It fills gaps, conforms to odd spaces, and remains effective longer than batt insulation.
Popular materials include:
- Cellulose (recycled paper-based, treated for fire and mold resistance)
- Fiberglass loose-fill (a budget-friendly, efficient option)
Blow-In vs. Batt: What’s the Better Choice?
| Feature | Batt Insulation | Blow-In (Loose-Fill) |
|---|---|---|
| Coverage | Prone to gaps & compression | Fills voids and nooks easily |
| Installation | Simple, but less airtight | More complex, better seal |
| R-Value per inch | Comparable | Comparable |
| Best For | New construction | Retrofits and upgrades |
