Open-Cell Foam
Often considered for interior assemblies where expansion, air sealing, and budget are part of the decision.
Spray foam insulation
Spray Foam Insulation in Arizona
Open-cell and closed-cell spray foam for homes, crawlspaces, attics, wall cavities, commercial buildings, and large open assemblies.
Start with the gaps
Spray Foam Insulation That Seals the Gaps
Spray foam insulation is one of HeatShield's core specialties. The service is built around sealing slow leaks through gaps, cracks, and cavities that standard insulation does not always reach.
The work applies to homes and commercial buildings, including crawlspace applications, wall cavities, attic areas, warehouse ceilings, and other open assemblies where the right foam choice depends on the building.
Open-Cell and Closed-Cell Decisions
Open-cell and closed-cell foam are different products. Open-cell foam is softer and more flexible, while closed-cell foam is denser and can be appropriate where moisture exposure or higher insulation value per inch matters.
The right recommendation comes after seeing the space. Every estimate starts with the assembly in front of us, not a one-size-fits-all product pitch.
Residential and Commercial Applications
Residential spray foam work can include attics, crawlspaces, rim joists, interior walls, and areas where energy escapes. Commercial projects require more planning because the areas are larger, schedules matter, and the work may need to happen around operations.
Every spray foam project should be planned around access, ventilation during application, surface preparation, and the specific product guidance for curing and re-entry.
Material choice
Open-Cell and Closed-Cell Are Different Tools
Closed-Cell Foam
Denser foam that may be used where its rigidity, insulation value per inch, or moisture behavior is appropriate.

Not Sure Which Foam Belongs Where?
The right answer depends on the assembly, access, moisture strategy, roof and attic condition, and what the property owner is trying to solve.

Questions
Spray Foam FAQ
What is the difference between open-cell and closed-cell spray foam?
Open-cell foam is softer and expands more. Closed-cell foam is denser and can be appropriate where higher insulation value per inch or different moisture characteristics matter. The right product depends on the space.
Can HeatShield install spray foam in existing homes?
Yes. Residential spray foam applications can include attics, crawlspaces, rim joists, interior walls, and existing spaces when access and assembly conditions fit the scope.
How long should I stay out of the space after installation?
Curing, ventilation, and re-entry guidance depend on the product and area. HeatShield should provide project-specific guidance before installation.
Do you also handle roofing if the issue starts above the attic?
Yes. HeatShield also has a roofing page, and the location pages explain how roof and insulation conditions can be connected in Arizona buildings.
