Seal your attic. Lock in comfort. Cut your energy bills.
Dallas-Fort Worth summers push past 100 degrees for weeks at a time. Attic temperatures in uninsulated DFW homes can hit 150 degrees or higher. That heat presses down through your ceiling and forces your AC system to run nonstop.
Spray polyurethane foam (SPF) insulation solves two problems at once. It blocks heat transfer and seals the air leaks that other insulation types leave behind. The EPA’s Energy Star program estimates that sealing cracks and air gaps can save homeowners up to 20% on monthly energy bills.
Green Attics is a fully certified and insured insulation contractor in Dallas-Fort Worth. We have installed spray foam across hundreds of DFW homes, from Plano and Frisco to McKinney and Prosper.
There are two types of spray foam. Each one works best in different parts of your home.
Open-Cell Spray Foam
Open-cell foam is lightweight and expands to roughly 3 inches per pass. The cells are not fully sealed, which makes the foam soft and flexible.
Open-cell foam is the most common choice for DFW attic insulation. At 5.5 inches thick, it reaches roughly R-20. At 7 to 10 inches, it can insulate a roofline and turn your attic into a semi-conditioned space.
Closed-Cell Spray Foam
Closed-cell foam is dense and rigid. The cells are fully sealed, which traps gas inside and gives the foam a higher R-value.
Many DFW projects use both types. Open-cell in the attic for coverage and cost control. Closed-cell in crawl spaces or rim joists where moisture is a concern. During your free energy audit, we will assess your home and recommend the right foam for each area.
Feature | Spray Foam (Closed-Cell) | Spray Foam (Open-Cell) | Blown-In Cellulose | Fiberglass Batts |
R-value per inch | R-6 to R-7 | R-3.5 to R-3.7 | R-3.2 to R-3.8 | R-2.9 to R-3.8 |
Air sealing | Yes | Yes | No | No |
Moisture barrier | Yes (at 1.5+ inches) | No | No | No |
Settling over time | None | None | Settles 10-20% | Can sag or compress |
Typical lifespan | 20-30+ years | 20-30+ years | 15-20 years | 10-25 years |
Soundproofing | Moderate | Excellent | Good | Moderate |
Pest resistance | High | Moderate | Low | Low |
Spray foam costs more upfront. But it is the only insulation type that seals air leaks and insulates in one step. If you are comparing blown-in attic insulation with spray foam, the right pick depends on your budget, your attic layout, and your energy goals. We cover this in detail in our blown-in vs spray foam comparison guide.

Don’t Take our word for it
We have completed spray foam installations in Celina, Gunter, Little Elm, and dozens of cities across the Dallas-Fort Worth metro.
We hire technicians who document every step and treat your home like their own.
Before we recommend spray foam, we run a Certified Performance Report to show you exactly where your home loses energy. No sales pitch. Just data.
Spray foam pairs well with radiant barriers, solar attic fans, and duct sealing. We handle all of it under one roof.
Every project starts with a free CPR energy audit. Here is what the full process looks like:
Most residential spray foam projects in DFW wrap up in one day.
Spray foam pricing depends on foam type, thickness, project size, and accessibility. Here are the typical ranges for DFW homes in 2026:
Factors that affect your final cost include attic access, whether old insulation needs removal, required thickness for target R-value, and whether your project needs a thermal barrier or ignition barrier for code compliance.
Most homeowners see a return on their spray foam investment within 5 to 7 years through lower energy bills. We provide a detailed quote after your free on-site energy audit. No guessing, no pressure.
At Green Attics, our team of comfort advisors brings years of field experience to every project. We give down-to-earth advice with a no-nonsense approach. Our technicians undergo continual training on insulation products, spray foam chemistry, building science, and HVAC technology to stay current with what works in DFW homes.
Most insulation materials slow heat transfer but do nothing about air leaks. Spray foam does both. It expands on contact, fills cracks and gaps around pipes, wiring, and framing, and hardens into a rigid or semi-rigid layer that blocks heat and air movement. In DFW’s climate, where attics can hit 150 degrees in summer, that airtight seal makes a measurable difference in comfort and energy costs. For a deeper look at how it compares with blown-in insulation, read our comparison guide.
Check your attic. If you see bare spots, sagging batts, or insulation that has been damaged by pests, water, or age, it is time for a replacement. Other warning signs include uneven room temperatures, high energy bills despite a working HVAC system, and visible daylight through your roof deck. If your current insulation is more than 15 years old and was not spray foam, upgrading to SPF can cut energy costs significantly. Schedule a free energy audit and we will tell you exactly where you stand.
Open-cell spray foam provides R-3.5 to R-3.7 per inch. Closed-cell provides R-6 to R-7 per inch. For DFW attics, the recommended R-value range is R-38 to R-49. Open-cell foam at 10 to 14 inches can reach those levels. Closed-cell foam gets there with 6 to 8 inches, which matters in spaces where every inch counts.
Yes. Once SPF is fully cured (typically within 24 hours), it is inert. It does not off-gas or release harmful chemicals. Our technicians follow all safety protocols during installation, including ventilation and protective equipment. After curing, the foam is non-toxic and safe for your family.
Spray foam insulation lasts 20 to 30 years or more. It does not sag, settle, or degrade the way fiberglass or cellulose can over time. The rigid or semi-rigid structure holds its R-value for the life of the product.
We use professional diagnostic tools to measure your home’s energy performance. Our CPR energy audit checks air infiltration, duct configuration, insulation levels, ventilation, and HVAC system efficiency. The audit gives you a clear picture of where energy leaves your home and what fixes will deliver the biggest savings.
Replace your insulation right away. Rodents and insects eat through existing insulation and contaminate what remains. Water-damaged insulation cannot be salvaged, and wet material breeds mold that can spread through your home. Green Attics handles insulation removal and replacement as a single project. We remove the old material, clean the attic, and install fresh spray foam.
