Open-Cell Spray Foam Insulation in DFW
Lightweight. Quiet. Extremely Effective for Texas Attics & Walls.
Serving Dallas, Fort Worth & the entire DFW Metroplex
When your goal is comfort, noise reduction, and strong energy savings without overbuilding cost, open-cell spray foam is often the ideal choice. TX Foam Pros installs high-performance open-cell foam in attics, walls, roof decks, and bonus rooms throughout Dallas–Fort Worth.
Open-cell foam expands aggressively, filling every gap and crack, creating a soft, airtight insulation layer that keeps your home cooler in the summer and more comfortable year-round.
What Is Open-Cell Spray Foam – And When Should You Use It?
Open-cell spray foam is a soft, flexible, expanding foam insulation. When sprayed, it rapidly expands to many times its liquid volume, filling cavities and sealing off air leaks.
Unlike closed-cell foam (which is dense and rigid), open-cell foam has tiny “open” cells that make it:
- Lightweight
- Highly expandable
- Great at absorbing sound
Ideal for interior applications
Open-Cell Foam Is Perfect For:
- Attic roof decks
- Attic floors (in the right assemblies)
- Interior walls
- Second-story and bonus rooms
- Media rooms / home theaters
- New construction framing
If you’re looking for the best insulation upgrade for comfort and quieter rooms inside the home, open-cell spray foam is often the top choice.
Problems Open-Cell Spray Foam Solves
Open-cell foam shines anywhere heat and air leakage are the main enemies:
🔥 Overheated Attics & Upstairs Areas
- Attics that feel like a furnace
- Hot game rooms / media rooms above the garage
- Second floors that never cool down
💸 High Cooling Costs
- AC running nonstop during DFW summers
- Electric bills that jump every warm month
🌬️ Drafts & Air Leaks
- Air coming through can lights, chases, and gaps
- Leaky knee walls and attic accesses
🔊 Noise Between Rooms or Floors
- Footstep noise from upstairs
- Sound transfer through interior walls
Open-cell foam stops unwanted air movement and helps stabilize temperature and sound inside the home.
Key Benefits of Open-Cell Spray Foam
✔ Serious Energy Savings
Open-cell spray foam reduces heat transfer and air leakage, helping many DFW homeowners cut cooling and heating costs by 20–35%.
✔ Superior Air Sealing
It expands into every gap and seam, creating a continuous insulated barrier – much more effective than fiberglass batts or blown-in insulation.
✔ Excellent Sound Control
The soft cellular structure absorbs airborne sound. Great for bedrooms, offices, media rooms, and shared walls.
✔ Comfort You Can Actually Feel
Rooms are less stuffy, less drafty, and more consistent from one side of the house to the other.
✔ No Sagging Like Fiberglass
Once cured, open-cell foam adheres to surfaces and stays in place for decades.
✔ Ideal for Complex Framing
Perfect for irregular cavities, vaulted ceilings, dormers, and tricky rooflines common in DFW homes.
Open-Cell vs Closed-Cell Spray Foam (What’s the Difference?)
We install both major spray foam types depending on performance requirements:
Open-Cell vs Closed-Cell – When Open-Cell Is the Better Choice
Both open-cell and closed-cell foams are powerful insulators, but they’re not interchangeable.
Open-Cell Foam – Best When:
- You’re insulating attics & walls
- Sound absorption is a priority
- You don’t need a built-in moisture/vapor barrier on that surface
You want maximum expansion and coverage at a lower material cost
Closed-Cell Spray Foam Best When
- You’re insulating metal buildings, crawl spaces, or exterior walls exposed to moisture
- You need a vapor barrier and extra rigidity
- You’re dealing with condensation or water spray
Where We Use Open-Cell Foam Most Often
🏠 Attic Roof Decks
The most common application. We spray open-cell foam directly to the underside of the roof deck to create a more stable, semi-conditioned attic space.
🧱 Interior Walls
Great for sound control between rooms, offices, nurseries, or media spaces.
🪜 Bonus Rooms & Rooms Above Garages
Open-cell foam helps stop heat and sound transfer between these problem areas and the rest of the home.
🏗 New Construction Homes
Builders who want efficient, quiet, and comfortable homes choose open-cell foam in strategic locations.
Open-Cell Spray Foam Cost in DFW
Open-cell foam is typically more budget-friendly than closed-cell foam, while still delivering massive improvements in comfort and performance.
Average Material Pricing
- Open-Cell: roughly $0.45–$0.75 per board foot (installed)
What Drives Pricing Up or Down?
- Total square footage
- Application thickness (R-value target)
- Whether existing insulation must be removed
- Accessibility (tight attics, complex rooflines, etc.)
- New construction vs retrofit
Most open-cell attic projects fall in the $3,000–$8,000 range in DFW, depending on size and complexity.e full ROI within 3–5 years through reduced energy usage alone.
Why DFW Homes Are a Great Fit for Open-Cell Foam
- Hot, long summers: Open-cell foam helps control attic and interior heat transfer.
- Lots of two-story homes: Great for upstairs comfort and sound control.
- Media rooms / bonus rooms: Open-cell improves both temperature and acoustics.
- Complex roof structures in newer builds: Foam reaches areas fiberglass can’t touch.
In short: if comfort and noise reduction inside the home are priorities, open-cell is usually the go-to choice.— spray foam is the best long-term protection

Open-Cell Spray Foam FAQ
-
Is open-cell spray foam good for attics in Texas?
Yes — open-cell is one of the most popular attic solutions in DFW due to its expansion, coverage, and sound dampening.
-
Does open-cell foam absorb moisture?
It can hold some moisture, but it also allows drying. It’s usually used where a dedicated vapor barrier is not required on that surface.
-
Is open-cell cheaper than closed-cell?
Yes — open-cell foam is generally less expensive per inch than closed-cell foam.
-
Will open-cell foam reduce noise?
Yes — it’s excellent for absorbing airborne sound and improving interior acoustics.
-
How long does open-cell spray foam last?
When properly installed, it can last 20–30+ years without sagging or falling out of place.
-
Can I use open-cell foam in a metal building?
We typically recommend closed-cell for metal buildings because of moisture and condensation. Open-cell is better for interior assemblies.
