Fiberglass Batt Insulation in Nashville and Middle Tennessee
Walls, Floors & Spray Foam

Fiberglass Batt Insulation

Precisely fitted batts in walls, floors and ceilings, cut around wiring and boxes so the cavity is filled without gaps or crushing.

Batts are the most familiar insulation, and they perform very well when they are installed with care. The difference between a good job and a poor one is almost entirely in the fit: batts that are crushed, folded or left with gaps lose much of their value.

We fit each batt to its cavity, split them around wiring and pipes, cut cleanly around boxes and trim the ends so they sit flat to the sheathing and the drywall. Where cavities are unusual, we use the right batt width and thickness instead of forcing the wrong one.

Fit is everything

A batt should fill the cavity fully, with no gaps at the edges and no compression. We measure cavities, choose the right size and cut each piece to fit, which is what a careful installer calls a Grade 1 installation.

Around wiring and boxes

Batts are split around wires and pipes, not stuffed behind them, and cut to wrap electrical boxes. This keeps the insulation full and the drywall flat.

Faced and unfaced

Paper or foil facing helps with vapor control in some assemblies and is unnecessary in others. We choose by the wall, the floor or the ceiling and the local conditions.

Floors, walls and ceilings

Batts also suit floors over crawl spaces, interior sound walls and ceilings under attics. Each location needs its own supports and details.

How it works

Our process, start to finish.

  1. 01

    Call and schedule

    You tell us what is going on, which rooms bother you and what you hope to change, and we set a time that fits your day.

  2. 02

    Inspect and assess

    We walk the attic, walls, crawl space and equipment, measure depths and use thermal imaging when it helps.

  3. 03

    Seal and prepare

    We protect the house, seal air leaks, place baffles and fix small problems so the insulation can do its job.

  4. 04

    Install the insulation

    Loose-fill, batts, foam or board goes in to the planned depth, with clean edges and clear markers.

  5. 05

    Verify and test

    We measure the result, take photos and test air leakage when the scope includes it.

  6. 06

    Walk through and enjoy

    We walk the finished work with you, answer questions and leave the site clean.

Questions

Fiberglass Batt Insulation FAQ

Are batts as good as spray foam?

Well-installed batts perform well for their cost. Spray foam seals air and adds more R per inch, so the right choice depends on the space and the budget.

Why do batts sometimes disappoint?

Gaps, compression and missed corners reduce performance. Careful installation is what makes the material work.

Can you add batts in an existing wall?

Only if the wall is open. Closed walls are better served by dense-pack cellulose or foam.

Do I need unfaced or faced batts?

It depends on the assembly. We pick the facing that suits your wall, floor or ceiling.

Are fiberglass batts itchy?

The fibers can irritate skin and eyes during installation, so installers wear protection. Once the drywall is on, it stays in the cavity.
