Attic Loose Fill Insulation in College Station & Bryan, TX

Blown-In Fiberglass Attic Insulation for Better Comfort, Lower Energy Bills & a More Efficient Home

If your home feels too hot in the summer, impossible to keep comfortable, or your electric bill makes you want to cry every month, your attic insulation may be the problem.

At LoneStar Air Sealers, we specialize in attic loose fill insulation, also known as blown-in fiberglass attic insulation, for homes and new construction throughout College Station, Bryan, and the surrounding Brazos Valley.

In Texas, your attic is one of the biggest sources of energy loss in your home. During the summer, attic temperatures can soar well above 130 degrees. Without proper insulation, that heat transfers into your home and forces your HVAC system to work overtime.

The result?

  • Higher electric bills
  • Hot and cold rooms
  • HVAC systems running nonstop
  • Uneven temperatures throughout the house
  • Reduced comfort year-round

Properly installed blown-in fiberglass insulation helps create a thermal barrier between your living space and the brutal Texas heat, improving comfort and helping your home perform the way it should.

What Is Attic Loose Fill Insulation?

Loose fill insulation is a fiberglass insulation material that is mechanically blown into the attic using specialized equipment. Instead of laying rolls or batts of insulation by hand, loose fill fiberglass creates an even blanket of insulation across the attic floor, helping improve coverage and thermal performance.

Blown-in fiberglass insulation works especially well because it fills gaps around wiring, framing, pipes, and hard-to-reach areas that batt insulation often misses.

The result is better consistency, improved thermal resistance, and a more comfortable home.

Why Homeowners Choose Blown-In Fiberglass Insulation

Better Energy Efficiency

One of the biggest reasons homeowners upgrade attic insulation is energy savings.

When your attic lacks sufficient insulation, heat moves into your living space quickly, especially during the brutal Texas summers. More attic insulation means your HVAC system doesn’t have to work as hard to maintain comfortable indoor temperatures.

Improved Comfort

Do certain rooms stay hotter than others? Upstairs impossible to cool? Cold spots in winter?

Those are classic signs of insufficient attic insulation.

Blown fiberglass insulation helps maintain more even temperatures throughout your home and reduces temperature swings between rooms.

Lower Utility Bills

Less heat gain means less strain on your air conditioner.

Many homeowners notice reduced heating and cooling costs after upgrading attic insulation, especially when existing insulation is old, compressed, or underperforming.

Full Attic Coverage

Unlike batt insulation, blown-in fiberglass can settle evenly around obstacles and hard-to-reach areas.

This creates more complete coverage across the attic floor and helps reduce thermal weak points.

Noise Reduction

As an added bonus, fiberglass insulation can also help reduce outside noise and sound transfer inside the home.

Attic Insulation Code Requirements in Bryan & College Station

Building codes exist for a reason — and unfortunately, many homes simply don’t have enough insulation.

For blown-in fiberglass attic insulation, local energy code requirements in our area commonly target:

Bryan, TX Attic Insulation Requirements

Homes in Bryan are commonly insulated to approximately R-38, which equals roughly 13.5 inches of blown-in fiberglass insulation.

College Station, TX Attic Insulation Requirements

Homes in College Station commonly require approximately R-49, which equals roughly 18.25 inches of blown-in fiberglass insulation.

These insulation levels help improve thermal performance, reduce heat transfer, and support better energy efficiency for homes in our climate. Recommended attic insulation levels in Texas commonly fall between R-38 and R-49 depending on climate zone and adopted code requirements.

Not sure how much insulation is in your attic?

Most homeowners have no clue — and honestly, that’s normal.

If you can see your attic floor joists sticking up above the insulation, there’s a good chance you may be under-insulated.

Attic Insulation for Existing Homes

Many older homes in Bryan and College Station were built with insulation standards far below what’s commonly recommended today.

Over time, insulation can settle, compress, shift, or become less effective.

We commonly see attics with:

  • Thin insulation coverage
  • Uneven insulation depths
  • Missed areas around penetrations
  • Gaps around wiring and plumbing
  • Insulation far below modern standards

For existing homes, we evaluate your attic and determine whether adding blown-in fiberglass insulation can improve performance.

In many cases, additional insulation can be installed over existing material if it is dry and in good condition.

New Construction Attic Insulation

Building a new home?

Now is the time to do insulation right.

Attic insulation is one of the most important components of a comfortable, energy-efficient house. Poor installation today can lead to high energy bills and comfort problems for years.

We work with builders and homeowners to install blown-in fiberglass insulation with proper depth, even coverage, and attention to detail.

More importantly, we understand that insulation works best when combined with proper air sealing.

Insulation slows heat transfer.
Air sealing stops air movement.

You need both.

That’s why many homeowners and builders pair attic insulation with professional attic air sealing to maximize comfort and efficiency.

Signs You May Need More Attic Insulation

You may benefit from additional attic insulation if:

✔ Your electric bills are unusually high
✔ Certain rooms stay hot or cold
✔ Your HVAC runs constantly
✔ Your attic insulation looks thin or uneven
✔ You can see attic joists above the insulation
✔ Your home feels drafty or uncomfortable
