Open-cell and closed-cell polyurethane foam that air-seals and insulates in one application — installed on roof decks, walls, and crawl spaces throughout Palm Harbor.
Spray foam is the only insulation on this list that stops air movement and heat transfer at the same time. In Palm Harbor, that matters more than the R-value on the label. A Pinellas County attic can run 130°F in August while the air handler fights to keep the house at 76°F, and most of that battle is lost through gaps — around can lights, at the top plates, where the soffit meets the roof deck. Foam seals those as it expands, which is why homes here often feel different within a day of the install rather than after a full billing cycle.
The reason spray foam keeps coming up in Palm Harbor is humidity, not temperature. Pinellas County homes lose comfort to moisture as much as to heat, and a vented attic pulls damp outside air across everything in it — including the ductwork. Closed-cell foam applied to the underside of the roof deck brings that whole volume inside the building envelope, so the ducts are no longer running through a hot, wet space. Homeowners describe the result as the air feeling drier, which is exactly what has happened.
Palm Harbor sits in Florida Climate Zone 2 — hot and humid, with a longer cooling season than almost anywhere else in the country. Under the Florida Building Code, Energy Conservation (8th Edition), the ceiling minimum here is R-38 and framed walls are R-13. ENERGY STAR recommends R-49 for an uninsulated attic in this zone; we build to R-38 to R-49 as the practical target.
| Item | Value | Where it applies |
|---|---|---|
| Open-cell foam | R-3.7 per inch | Roof decks, interior walls, sound control |
| Closed-cell foam | R-6.5 to R-7.0 per inch | Roof decks, crawl spaces, block walls, flood-prone areas |
| Air sealing | Effectively eliminates envelope air leakage at the application surface | Both types |
| Vapor behavior | Closed-cell is a Class II vapor retarder at 1.5" and above | Closed-cell only |
We inspect the attic, roof deck condition, duct location, and any existing insulation, and confirm the roof has enough service life left to justify foam.
Existing insulation is removed where required, penetrations are prepped, and the work area and HVAC returns are masked and protected.
Foam is sprayed in controlled lifts to the specified thickness, checked with a depth gauge as we go rather than by eye.
The space is ventilated per the manufacturer's re-occupancy schedule before anyone goes back in.
We measure thickness, photograph the finished surface, and hand over documentation for permits, insurance, or a future sale.
Spray foam in Palm Harbor typically runs $3.00 to $7.00 per square foot depending on foam type and thickness. A full closed-cell roof deck encapsulation on a 2,000 sq ft Palm Harbor home usually lands between $6,000 and $13,000; open-cell on the same deck is meaningfully less.

Palm Harbor sits in Florida Climate Zone 2 — hot and humid, with a longer cooling season than almost anywhere else in the country. The Florida Building Code, Energy Conservation (8th Edition) sets a R-38 minimum for ceilings in this zone, and R-38 to R-49 is the practical target for comfort and utility savings. Many Palm Harbor homes built before 2005 still measure R-11 to R-19, which is a large part of why their summer bills run high.
Insulation-only retrofits in Pinellas County usually do not require a permit, but new construction, additions and commercial work do, and the requirement is set locally rather than statewide. We confirm with the Pinellas County building department before we start, and we link to their site below so you can check for yourself.

Cooling is roughly half of a typical Palm Harbor electric bill. Bringing an under-insulated attic up to a properly air-sealed R-38 to R-49 commonly cuts the cooling portion by 20 to 30 percent — more if your ductwork runs through the attic. On a $300 summer bill that is usually $30 to $45 a month back.
These are the outside sources we work from. None of them are ours — check them yourself before you sign anything with any contractor.
