Green Attics installs blown-in attic insulation across the Dallas-Fort Worth metro. Our 3-part attic insulation system combines insulation removal of old material, thorough air sealing of your attic floor, and fresh blown-in fiberglass installed to R-38 or higher. That combination can cut your energy bill by up to 60%.
We use Knauf EcoFill, a formaldehyde-free fiberglass blowing insulation rated for residential and commercial applications. Every project starts with a free Certified Performance Report (CPR), our energy audit that pinpoints where your home loses energy before we touch a single bag of insulation.
spaces for this zone. That translates to roughly 13 to 15 inches of blown-in fiberglass.
Most DFW homes built before 2000 fall short of that standard. Many have R-19 or less, which means nearly twice the heat transfer compared to R-38. During a typical Texas summer, attic temperatures reach 140°F or higher. Without proper insulation, that heat radiates through your ceiling and forces your air conditioning to run overtime.
Blown-in fiberglass insulation solves this problem by filling gaps, covering joists, and creating a continuous thermal blanket across the entire attic floor. Unlike batt insulation, it conforms to irregular shapes, wiring, pipes, and ductwork without leaving voids.
Green Attics does not just blow insulation over whatever is already there. Our process has three steps, and skipping any of them reduces performance.
Part 1
Remove Old or Damaged Insulation
Old insulation traps dust, allergens, rodent droppings, and moisture. If your existing insulation is contaminated, compressed, or below R-19, we remove it first. Our insulation removal service uses commercial-grade vacuum equipment to clear the attic floor safely. This step also exposes the ceiling plane so we can seal air leaks properly.
Part 2
Seal the Attic Floor
Air sealing is the step most insulation companies skip. It is also the step that determines whether your new insulation actually performs. We seal gaps around electrical penetrations, plumbing stacks, HVAC boots, recessed light cans, top plates, and the attic hatch. Without this step, conditioned air leaks into the attic through dozens of small openings, and no amount of insulation fixes that.
Part 3
Blow In New Insulation to R-38+
We install Knauf EcoFill blown-in fiberglass to a minimum depth of 13 inches, achieving R-38 or higher depending on your home’s needs. Installation takes one day for most homes. Our technicians use depth markers every 300 square feet per code requirements and verify bag count against square footage to confirm uniform coverage.
Choosing the right insulation type depends on your attic layout, budget, and goals. Here is how the three main options compare for DFW attics.
Blown-in fiberglass is the most common choice for existing homes. It fills irregular spaces, installs quickly, and costs less than spray foam. R-value runs about 2.2 to 2.7 per inch. Best for standard vented attics with accessible floor space.
Spray foam insulation provides a higher R-value per inch (3.7 for open-cell, 6.5 for closed-cell) and doubles as an air barrier. It costs more but works well in sealed attic designs or attics with HVAC ductwork in the conditioned space. Green Attics installs both open-cell and closed-cell spray foam.
Batt insulation (rolls) is the least expensive option but the hardest to install correctly. It leaves gaps around wiring, pipes, and framing, which creates thermal bridges. For retrofit projects, blown-in outperforms batt insulation in coverage and long-term R-value retention.
For many DFW homeowners, blown-in fiberglass paired with a radiant barrier is the best value combination. The radiant barrier reflects heat before it reaches the insulation, and the blown-in fiberglass slows conductive heat transfer. Together, they can reduce attic temperatures by 20 to 30 degrees.
Most blown-in attic insulation projects take a single day. Here is the typical timeline.
Success Stories
Our free CPR energy audit gives you a data-driven report showing exactly where your home wastes energy. No guesswork, no pressure. You see the numbers and decide.
Our technicians complete continuing education on insulation innovations, building science, and HVAC technology so every installation meets current best practices.
We offer flexible financing options so you can start saving on energy costs now and pay over time.
Not sure if your insulation needs replacing? Here are the most common indicators.
If you notice any of these, schedule a free energy audit. Our CPR report tells you your current R-value and what it will take to reach R-38 or higher.
Standard attic insulation breaks down over time. Old fiberglass turns into fine dust particles that enter your HVAC system and circulate through your home. That dust triggers allergies, aggravates asthma, and degrades indoor air quality.
Knauf EcoFill is a dust-free blown-in product. It does not settle, shed fibers, or degrade the way older insulation does. Paired with air purifiers and UV lights, a fresh insulation installation can transform the air quality in your home.
Grab a ruler and measure the depth of your existing insulation. If it is under 10 inches, you are likely below R-30 and well under the R-38 minimum for North Texas. Other signs include high energy bills, uneven room temperatures, and visible contamination from pests or water damage.
Our Certified Performance Report (CPR) uses diagnostic equipment to identify every source of energy loss in your home, from air infiltration and duct leaks to insulation gaps and HVAC inefficiency. You get a prioritized list of fixes with estimated savings for each.
North Texas falls in IECC Climate Zone 3. The minimum code requirement is R-38 for attics. Green Attics recommends R-38 to R-49 depending on your home’s age, HVAC configuration, and whether ductwork runs through the attic. Higher R-values yield diminishing returns, so we help you find the sweet spot between performance and cost.
It depends. If your existing insulation is clean, dry, and undamaged, we can blow new insulation on top. If it shows signs of moisture, mold, pest contamination, or heavy compression, removal is the right call. Our CPR audit determines which approach fits your situation.
The three main types for attic applications are blown-in fiberglass, spray foam, and batt (roll) insulation. Each has different R-values per inch, costs, and ideal use cases. Blown-in fiberglass is the most common for retrofit attic projects in DFW because of its coverage, performance, and cost efficiency.
Rodents and insects eat through insulation and contaminate it with droppings and urine. If you find evidence of pest activity, the insulation should be removed and replaced. Our insulation removal service handles contaminated material safely before we install fresh insulation.
Wet insulation loses its R-value and cannot be salvaged. Moisture also promotes mold growth that can spread through your home. Fix the source of the leak first, then schedule insulation removal and replacement. We can identify moisture issues during your free CPR audit.
Yes. We offer financing options that let you spread the cost of your insulation project into manageable payments. Many homeowners find that the monthly energy savings offset the financing payment.
Federal tax credits under the Inflation Reduction Act (Section 25C) may cover up to 30% of insulation and air sealing costs, up to $1,200 per year. Some local DFW utilities also offer rebates for insulation upgrades. Ask our team during your CPR audit for current details.
