Spray Foam Insulation
Spray foam does two jobs at once — it insulates and it air-seals. In the Florida heat, that combination is hard to beat, because most of the energy you lose is not through the insulation itself but through the gaps, cracks, and penetrations that let hot, humid air pour into your attic and walls. P1Mitigators™ coordinates open-cell and closed-cell spray foam installation across Jacksonville and Duval County.
We work with vetted foam crews to spray your attic roof deck, wall cavities, rim joists, and crawl spaces — expanding to fill and seal every gap in one pass. Done right, spray foam can turn a blistering attic into a semi-conditioned space and take a real bite out of your cooling load.
Foam is the premium end of the insulation world, so we will tell you straight where it earns its keep and where blown-in or batt is the smarter spend. Because we coordinate the whole envelope, we can combine foam with traditional insulation and ventilation in one plan instead of overselling you on a single product.
What Spray Foam Insulation Includes
Closed-Cell Spray Foam
Dense, high-R foam that air-seals, insulates, and adds rigidity and moisture resistance — ideal for crawl spaces, rim joists, and areas where space is tight and performance matters most.
Open-Cell Spray Foam
Lighter, expanding foam that fills large cavities and roof decks for strong air-sealing and sound-dampening at a lower cost per board foot — a common choice for attic roof lines.
Attic Roof Deck & Wall Foam
Sealing the underside of the roof deck to bring the attic into the conditioned envelope, plus wall-cavity foam on new work and renovations for a tight, quiet home.
Crawl Space & Rim Joist Sealing
Foaming rim joists and crawl-space walls to stop humid air, drafts, and moisture at one of the leakiest points in a Florida home.
Why It Matters
- Insulates and air-seals in a single application
- Stops the hot, humid air infiltration that drives cooling bills
- Closed-cell adds moisture resistance and rigidity
- Honest guidance on where foam pays and where it does not
- Combined with blown-in, batt, and ventilation in one plan

Frequently Asked Questions
What is the difference between open-cell and closed-cell spray foam?
Closed-cell foam is dense, has a higher R-value per inch, resists moisture, and adds structural rigidity — best where space is limited or moisture is a concern. Open-cell is lighter, expands more to fill large cavities, dampens sound, and costs less per board foot. We recommend the right one for each area of your home.
Is spray foam worth it in the Florida climate?
It can be, especially for sealing an attic roof deck or crawl space where hot, humid air infiltration is the real problem. Because foam air-seals as it insulates, it attacks the leaks that ordinary insulation cannot. We will tell you honestly where foam earns its cost and where blown-in is the better value.
Can you spray foam an existing attic?
Yes, in many cases. Spraying the underside of the roof deck turns a hot vented attic into a semi-conditioned space. It requires proper prep and ventilation planning, which we scope before we start so it is done correctly.
Who does the installation?
P1Mitigators™ coordinates and manages the project; the spray foam is applied by vetted, experienced foam crews. You get one point of contact and a contractor who has been vetted.
