What Is Fiberglass Insulation?

Fiberglass insulation is made from extremely fine glass fibers formed into batts, rolls or loose-fill material. These fibers create small air pockets that slow heat transfer through your home’s walls, ceilings, floors and attic.

Homeowners frequently choose fiberglass because it is:

  • Cost-effective

  • Energy efficient when properly installed

  • Available in multiple R-values

  • Suitable for new and existing homes

  • Useful for thermal and sound control

  • Compatible with many common building assemblies

  • Available as batts or blown-in insulation

Proper installation matters. Gaps, compression and incomplete coverage can significantly reduce its performance.

Types of Fiberglass Insulation We Install

  • Fiberglass Batt Insulation

    Fiberglass batts are pre-cut sections designed to fit between wall studs, floor joists and ceiling framing. They are commonly installed during new construction and remodeling projects while the wall and ceiling cavities are open.

    Common residential applications include:

    • Exterior walls

    • Interior walls

    • Ceilings

    • Floors

    • Attics

    • Basements

    • Crawl spaces

    • Garages

    • Home additions

    • Bonus rooms

  • Kraft-Faced Fiberglass Batts

    Kraft-faced fiberglass has an attached paper facing that may serve as a vapor retarder in certain building assemblies. Whether it is appropriate — and which direction the facing should be installed — depends on the location, climate and construction of the home.

    Because kraft paper is combustible, it must be installed according to product instructions and applicable building requirements.

  • Unfaced Fiberglass Batts

    Unfaced fiberglass does not include an attached paper or foil layer. It may be appropriate where a separate vapor-control layer is present or where a facing is not required.

    It is frequently used for:

    • Interior walls

    • Floor and ceiling assemblies

    • Sound reduction

    • Layering over existing insulation

    • Certain attic applications

  • Blown-In Fiberglass Insulation

    Blown-in fiberglass, also called loose-fill insulation, is installed using specialized equipment. The loose material settles around framing, wiring, ductwork and other irregular areas where fiberglass batts may be difficult to install.

    It is commonly used for:

    • Open attics

    • Existing attic upgrades

    • Hard-to-reach areas

    • Irregular framing

    • Adding insulation over an appropriate existing layer

    • Residential retrofit projects

Benefits of Fiberglass Insulation

  • More Consistent Indoor Comfort

    Properly installed fiberglass helps slow heat transfer between your living space and unconditioned areas. This can reduce drafts, uneven temperatures and uncomfortable hot or cold rooms.

  • Improved Energy Efficiency

    Insulation helps keep heated and cooled air inside the home. This can reduce unnecessary strain on your HVAC system and support lower energy use. Actual savings depend on your home’s construction, existing insulation, air leakage, HVAC system and household habits.

  • Affordable Performance

    Fiberglass generally offers reliable thermal performance at a lower initial cost than some other insulation materials. This makes it a popular option for new homes, additions, renovations and attic upgrades.

  • Noise Reduction

    Fiberglass can help absorb sound traveling between rooms and floors. It is often installed in interior walls around bedrooms, bathrooms, laundry rooms, home offices, entertainment rooms and more.

  • Fire-Performance Options

    Unfaced fiberglass insulation is noncombustible. However, some facings and related materials may be combustible. Each product must be installed according to its listed application and applicable building requirements.

  • Moisture and Mold Considerations

    Fiberglass itself does not provide a food source for mold. However, mold can grow on dust, paper facings and surrounding building materials when moisture is present. Fiberglass should not be used to cover an unresolved roof leak, plumbing leak, drainage issue or excessive humidity. Wet or contaminated insulation may need to be removed before new material is installed.

Frequently Asked Questions

Is fiberglass insulation a good choice for homes in Middle Tennessee?

Yes. Properly installed fiberglass can provide dependable thermal performance through Middle Tennessee’s hot summers and changing winter temperatures. The appropriate product and R-value depend on where it will be installed.

What is the difference between fiberglass batts and blown-in fiberglass?

Fiberglass batts are pre-cut sections installed between framing members. Blown-in fiberglass is loose material installed with specialized equipment, making it useful for open attics and irregular areas.

Can fiberglass insulation lower my energy bills?

Fiberglass can help reduce unwanted heat transfer and support lower energy use. Actual savings vary based on the home, HVAC system, air leakage, existing insulation and household habits.

Can fiberglass help make my home quieter?

Yes. Fiberglass can absorb sound traveling through interior walls, ceilings and floors. It is commonly installed around bedrooms, bathrooms, laundry rooms and home offices.

Is fiberglass insulation fire-resistant?

Unfaced fiberglass insulation is noncombustible. Kraft paper and certain other facings may be combustible and must be installed according to applicable product and building requirements.

Does fiberglass prevent mold?

Fiberglass itself does not provide food for mold, but mold can grow on dust, paper facings and surrounding materials when moisture is present. Leaks and humidity problems should be addressed before new insulation is installed.

Can new fiberglass be added over my existing attic insulation?

Sometimes. Existing material should first be checked for moisture, pest contamination and deterioration. Wet, contaminated or severely damaged insulation may need to be removed.

Does Complete Insulation remove old insulation?

Yes. We provide residential insulation removal and can prepare accessible attics, crawl spaces and other areas for new fiberglass or spray foam.
