Attic Insulation Types: Which is Best for Memphis Homes?

Attic Insulation Types: Which is Best for Memphis Homes?

Aug 21 2025

Choosing the right attic insulation can feel overwhelming—but it doesn’t have to be. Each insulation type has its own strengths and challenges. To help you make an informed decision, we’re outlining the most common attic insulation options and why our new blow‑in fiberglass solution from Restoration Roofing may be the perfect fit for homes in Memphis and surrounding suburbs.


1. Batt (Rolled) Insulation

Description:
Arch-shaped or flat rolls of fiberglass or mineral wool designed to fit snugly between attic joists.

Pros:

  • Affordable and widely available

  • Easy to install for professionals

  • Ideal for new construction or accessible, open spaces

Cons:

  • Gaps and compression reduce R‑Value effectiveness

  • Labor-intensive around obstructions (pipes, vents, wiring)

  • Not ideal for DIY if aiming for tight coverage


2. Blow‑In (Loose‑Fill) Insulation

Description:
Material—typically fiberglass or cellulose—blown into place using specialized equipment for even, dense coverage across attic surfaces.

Pros:

  • Fills gaps and conforms to irregular spaces

  • Easy to add on top of existing insulation layers

  • High R‑Value potential when installed to recommended depth

Cons:

  • Requires professional installation equipment

  • Needs consistent density to maintain performance

Restoration Roofing’s Offering:
We’re thrilled to now provide blow‑in fiberglass insulation throughout Memphis, Collierville, Germantown, and nearby areas. Fiberglass is durable, mold-resistant, and performs exceptionally well in humid climates.


3. Spray Foam Insulation

Description:
Applied as a liquid that expands into solid foam, sealing all air leaks and gaps while providing insulation.

Pros:

  • Highest air-sealing performance

  • Durable and long-lasting

  • Excellent moisture barrier

Cons:

  • Significantly more expensive

  • Requires professional installation with safety precautions

  • Not easily upgraded or altered


4. Rigid Foam Board Insulation

Description:
Stiff panels (e.g., polystyrene, polyiso) installed over attic floors or underside of roof decks for enhanced R‑Value.

Pros:

  • High R‑Value per inch

  • Continuous coverage with minimal seams

  • Adds structure and thermal barrier

Cons:

  • More costly than loose‑fill or batts

  • Complex-fitting around attic geometry and fixtures

  • Best paired with other insulation for full effectiveness


R‑Value 101: Why It Matters in Memphis

R‑Value measures insulation’s ability to prevent heat transfer—the higher the rating, the better it works. In Memphis’s climate—long, hot summers and mild winters—the recommended attic insulation level is R‑30. This level helps maintain indoor comfort and control energy costs.

Here’s how common materials stack up:

Insulation TypeR‑Value per InchApprox. Thickness to Reach R‑30
Fiberglass BattsR‑3.0 – R‑3.5~9 to 10 inches
Blow‑In FiberglassR‑2.5 – R‑2.8~11 to 12 inches
Spray FoamR‑6 to R‑7~4 to 5 inches
Foam BoardR‑5 to R‑6~5 to 6 inches

Why Restoration Roofing Recommends Blow‑In Fiberglass for Memphis Homes

  1. Ideal R‑Value Coverage:
    Easily achieves R‑30 with applied thickness and ensures all nooks are covered for consistent insulation.

  2. Humidity Resistance:
    Fiberglass doesn’t absorb water, helping to prevent mold—a big plus in our humid climate.

  3. Cost-Effective & Efficient:
    Less expensive than spray foam and more effective than compressed batts, offering great value for performance.

  4. Seals Well:
    The blowing process ensures there are no gaps or voids—common weaknesses in traditional batts.

  5. Future-Proof Solution:
    Because it can be topped up or combined with upgrades later, you can maintain ideal R‑Value over time.


When to Consider Other Options

  • Spray foam is best when airtight sealing is a top priority, such as for moisture control or in conditioned attics.

  • Foam board works well for attic lid applications or when space is limited but high R‑Value is needed.

  • Existing batt insulation may suffice if pristine, dense, and already meeting R‑30—but many older installations fall short from settling or gaps.


How Our Installation Process Works

  1. Free Attic Assessment: We check current insulation levels, air leaks, and ventilation.

  2. Recommendation & Estimate: You’ll get a tailored proposal to reach at least R‑30.

  3. Clean Installation: Using professional blowers, we install loose-fill fiberglass accurately and cleanly.

  5. Final Inspection: We ensure coverage depth is uniform and verify your home’s energy efficiency benefits.
