Attic Insulation Services in Fort Worth, TX
In Fort Worth, where triple-digit summers meet aging insulation, it doesn’t take long for energy bills to climb. The average Fort Worth household pays about $174 per month for electricity. Air conditioning alone accounts for 50 to 60 percent of that cost during summer. Most of that wasted energy escapes through one place: a poorly insulated attic.
Green Attics installs blown-in fiberglass and spray foam attic insulation in Fort Worth, TX, built to meet or exceed R-38, the minimum R-value required for this climate zone. Whether you’re in a 1940s Fairmount bungalow or a 2015 Alliance build, we find the gaps and seal them.
We start every project with a free Certified Performance Report (CPR). It gives you a clear, no-pressure assessment of where your home is losing energy and what it costs you each month.

Attic Insulation Services for Fort Worth Homes
Fort Worth homes vary in age, layout, and condition. A one-size approach to insulation doesn’t work here. We match the material and method to your home’s structure.
Blown-In Fiberglass Insulation
Blown-in attic insulation is the most common upgrade for Fort Worth attic floors. We use Knauf EcoFill, a fiberglass blowing insulation designed for both thermal resistance and sound absorption. At 12 to 13 inches of depth, blown-in fiberglass reaches R-38. It fills around joists, wiring, and junction boxes evenly, which makes it well suited for attics with irregular framing or tight corners.
Blown-in fiberglass is the right fit when you need full attic floor coverage at a reasonable cost. It works especially well in homes where the existing insulation has settled or compressed below code levels.
Spray Foam Insulation
Spray foam creates both insulation and an air seal in one application. That dual function makes it the stronger choice where air leaks are the primary problem.
Closed-cell spray foam delivers R-6 to R-7 per inch and adds structural rigidity. It also acts as a moisture barrier. Open-cell spray foam reaches about R-3.7 per inch, expands to fill irregular cavities, and provides solid sound dampening. Both types outperform traditional insulation at stopping air infiltration.
Spray foam is the better option for roof decks, rim joists, crawl spaces, and areas around can lights or plumbing penetrations where blown-in material can’t form a tight seal.
Many Fort Worth projects combine both. Blown-in on the attic floor for cost-effective thermal resistance. Spray foam at penetration points and the rim joist for air sealing.
Radiant Barrier Installation
Radiant barriers reflect radiant heat before it reaches the attic floor. In Fort Worth summers, unshielded attics regularly exceed 150°F. A properly installed radiant barrier can cut attic temperatures by 20 to 30 degrees. That reduces the thermal load on your insulation and lowers the cooling demand on your HVAC system.
Radiant barriers work best as a complement to blown-in or spray foam insulation, not a replacement. Together, they address all three forms of heat transfer: conduction, convection, and radiation.
Insulation Removal
Old insulation loses R-value over time. It compresses, absorbs moisture, and collects dust, rodent debris, or mold. When existing material is damaged or contaminated, our insulation removal crew clears it out safely before installing fresh material. We vacuum the old material, sanitize the attic deck, and prep the space for a clean install.
Fort Worth R-Value Requirements and What Your Attic Probably Has
Fort Worth sits in IECC Climate Zone 3. Under current Texas energy code, attic insulation in this zone must reach a minimum R-value of R-38. Wall insulation requires R-20 (or R-13 cavity plus R-5 continuous). Ducts in unconditioned spaces like attics need R-8 insulation.
Most Fort Worth homes built before 2015 fall short of R-38. Many older homes in Ridglea, Fairmount, or Meadowbrook have R-19 or less. Some have as little as R-11, which is roughly 3.5 inches of aged fiberglass batts. That gap between what your attic has and what the code calls for translates directly into higher energy bills, especially from June through September when your AC runs hardest.
Green Attics measures your current insulation depth during every energy audit and recommends the right material and thickness to meet or exceed R-38.
Blown-In vs. Spray Foam: Choosing the Right Insulation for Your Fort Worth Home
Both materials work well in North Texas. The right choice depends on your home’s construction, your goals, and where the insulation needs to go.
Blown-in fiberglass is the cost-effective choice for attic floors. It achieves R-38 at 12 to 13 inches, installs in a few hours, and costs between $1.50 and $2.50 per square foot installed. For a 1,500 square foot attic, expect a total in the range of $2,250 to $3,750. This is the right starting point for most Fort Worth homeowners upgrading from thin or settled insulation.
Spray foam costs more upfront, between $3 and $7 per square foot installed, depending on open-cell vs closed-cell and application depth. For a 1,500 square foot attic, spray foam can run $4,500 to $10,500. The higher cost reflects the air-sealing benefit, which blown-in alone can’t match. Homes with significant air leakage, cathedral ceilings, or conditioned attic spaces get the most value from spray foam.
When to combine both: Use blown-in fiberglass on the attic floor for bulk thermal resistance. Apply spray foam at the rim joist, around duct boots, and at penetrations where air leaks are concentrated. This combined approach gives you R-38 coverage and a tight building envelope without the full cost of spraying the entire attic.
Our CPR audit identifies the specific approach your home needs, so you’re not overspending on spray foam where blown-in does the job, or underspending on air sealing where leaks are the real problem.
Signs Your Fort Worth Home Needs New Attic Insulation
Not sure if your insulation is the problem? Here are the most common signals Fort Worth homeowners notice before calling us:
- Second floor stays 5 to 10 degrees warmer than the first floor, even with the AC running
- Electric bills spike above $250 per month in July and August
- Rooms closest to the attic feel warm to the touch on summer evenings
- Your HVAC system runs constantly but never seems to catch up
- Visible insulation in the attic is thin, uneven, or compressed below the tops of the joists
- You spot light gaps, pest droppings, or moisture stains in the attic space
If your home was built before 2015, it almost certainly has less than R-38 in the attic. Our CPR audit measures your current insulation depth, identifies air leaks, and gives you a prioritized plan.

Fort Worth Home Types We Commonly Insulate
Fort Worth has one of the most diverse housing stocks in DFW. Each construction era creates different insulation challenges:
Pre-1970 homes
(Fairmount, TCU area, Polytechnic Heights) often have little or no attic insulation. Some have original rock wool batts that have settled to under 2 inches. These homes benefit most from full insulation removal, air sealing, and a fresh blown-in install to R-38.
1970s to 1990s homes
(Ridglea, Westover Hills, Wedgwood) usually have fiberglass batts at R-11 to R-19, well below current code. Adding blown-in fiberglass on top of existing batts brings these homes up to R-38 without the cost of removal.
2000s to present
(Alliance, North Fort Worth, Sendera Ranch) may have R-30 or higher but often suffer from duct leakage and missing air sealing at top plates and penetrations. Spray foam at key leak points plus duct sealing fixes the real issue.
What You Get After a Professional Insulation Upgrade
Adding modern insulation to a Fort Worth attic pays off in measurable ways:
- Lower monthly energy bills, typically 15 to 30 percent for homes upgrading from R-19 or below
- Even indoor temperatures, eliminating hot upstairs rooms and cold spots
- Reduced HVAC strain, which means fewer repair calls and a longer system life
- Cleaner indoor air when paired with air sealing and duct cleaning
- Quieter living spaces from improved sound absorption
- Higher resale value with documented energy improvements
Fort Worth homes on the Oncor grid average about 1,140 kWh per month. Cutting that by even 15 percent saves over $300 per year at current rates. Homes that add air sealing to their insulation upgrade typically see savings on the higher end of that range.
Common Insulation Problems in Fort Worth Homes
- Insulation depth below R-19 in homes built before 2000
- Attic temperatures exceeding 150°F in summer due to missing radiant barriers
- Air leaks at top plates, can lights, and plumbing penetrations that bypass insulation entirely
- Duct leaks wasting 20 to 30 percent of conditioned air before it reaches living spaces
- Moisture buildup in attics that compresses insulation and breeds mold
- Old insulation contaminated by rodent activity or water intrusion
Our solutions combine insulation, air sealing, radiant barriers, solar attic fans, and duct work to fix these problems at the source, not just cover them up.

Frequently Asked Questions
How do I know if my Fort Worth home needs new attic insulation?
If your home was built before 2015, it likely falls below the R-38 minimum required for Climate Zone 3. Visible signs include thin or uneven insulation that sits below the tops of the joists, hot upper floors, and summer electric bills consistently above $200. Our CPR audit measures your current depth and gives you exact numbers.
What type of insulation is best for a Fort Worth attic?
Blown-in fiberglass is the best value for most attic floors. It reaches R-38 at 12 to 13 inches and installs quickly. Spray foam is the better choice for roof decks, crawl spaces, and areas with heavy air infiltration. Many projects use both.
How much does attic insulation cost in Fort Worth?
Blown-in fiberglass runs about $1.50 to $2.50 per square foot installed. Spray foam runs $3 to $7 per square foot depending on type and depth. For a 1,500 square foot attic, blown-in typically costs $2,250 to $3,750. Spray foam for the same area ranges from $4,500 to $10,500. Our CPR audit helps you spend where it matters most.
How long does attic insulation installation take?
Most blown-in insulation projects are completed in a single day. Spray foam applications may take a day or two depending on the scope. Combined projects, including insulation removal and new installation, can also be completed in one day for most homes.
What R-value does my Fort Worth attic need?
Fort Worth is in IECC Climate Zone 3. The code minimum is R-38 for attics. Homes built before 2015 often have R-19 or less. We measure your current level during the CPR audit and recommend the right depth and material.
Are there tax credits or rebates for insulation in 2026?
The federal Section 25C Energy Efficient Home Improvement Credit expired on December 31, 2025. That credit covered 30 percent of insulation material costs up to $1,200 per year. As of 2026, it is no longer available for new projects. Local utility rebates and incentive programs may still apply. We stay current on available programs and will let you know what options exist during your CPR audit. Check with your tax advisor for the latest details.
Does adding insulation help if my AC is old?
Yes. Insulation reduces the cooling load your AC has to handle. Even an older system will run less and last longer when the attic above it is properly insulated and sealed. If your system does need replacement, we offer AC installation alongside insulation upgrades, so the new system is sized for the improved thermal envelope.
What is air sealing and why does it matter?
Air sealing closes the gaps around attic hatches, recessed lights, plumbing stacks, and electrical boxes where conditioned air escapes. The Department of Energy estimates these leaks account for 25 to 40 percent of a home’s heating and cooling loss. Sealing them before insulating lets the new material perform at its full R-value.
