Attics and rooflines
Improve comfort by reducing heat gain and uncontrolled air movement.
Spray Foam Insulation
DFW Spray Foam Insulation for Homes, Attics, and Metal Buildings
Seal in comfort, save energy and say goodbye to drafts and inconsistent temperatures. Thermal Plan uses building science, testing and a whole-building assessment process to decide where spray foam belongs and how it should work with the rest of your building.

Why Spray Foam
Spray foam solves comfort problems ordinary insulation can miss
Traditional insulation can slow heat movement, but it does not always stop air leakage, moisture movement, hot rooms, cold rooms or uncomfortable metal buildings. Spray foam helps fill gaps, cracks and hard-to-reach areas while creating a stronger thermal barrier.
- Helps reduce uncontrolled air leakage
- Improves comfort in hot summers and cold winters
- Supports attic, wall, roofline and metal-building performance
- Can help manage condensation risks when designed correctly
- Works best when paired with building diagnostics, not guesswork
Best Fit
Where spray foam can make the biggest difference
Retrofits and reinsulation
Address comfort problems in existing homes where older insulation is underperforming.
Additions and remodels
Build the envelope correctly before comfort problems get baked in.
Metal buildings and shops
Closed-cell spray foam can help control temperature swings and condensation.
Our Process
The right insulation starts with the right diagnosis
Thermal Plan does not treat spray foam like a one-size-fits-all product. The assessment looks at comfort complaints, air leakage, moisture risks, ventilation, existing insulation and the way the building is actually being used.
- 1
Assess the building and comfort problems.
- 2
Identify air leakage, insulation gaps and moisture risks.
- 3
Recommend the right assembly and spray foam type.
- 4
Install with the surrounding building system in mind.
- 5
Review performance considerations after the work is complete.
Foam Type
Closed-cell or open-cell spray foam?
The answer depends on the building, the assembly and the problem being solved. Closed-cell spray foam is often useful where higher R-value per inch, added rigidity or condensation control are important. Open-cell spray foam may be appropriate in other assemblies where vapor behavior, depth and budget point in a different direction.
The goal is not simply to add foam. The goal is to create a building envelope that is comfortable, durable and efficient.

Questions
Common questions about spray foam insulation
Is spray foam always better than traditional insulation?
No. Spray foam is powerful when it solves the right problem in the right assembly. In some homes, air sealing, ventilation or targeted reinsulation may matter just as much as the foam itself.
Can spray foam help with hot rooms or uncomfortable attics?
It can, especially when the discomfort is tied to air leakage, attic heat gain or poor envelope performance. Thermal Plan starts with diagnostics so the recommendation is based on the building.
Is closed-cell spray foam good for metal buildings?
Closed-cell spray foam is often a strong fit for metal buildings because it can add insulation value and help control condensation when specified correctly.
Do I need an assessment before getting a spray foam quote?
An assessment helps avoid buying insulation without understanding the building problem. It gives the project a better chance of improving comfort, efficiency and durability.
