Open-cell and closed-cell polyurethane foam that air-seals and insulates in one application — installed on roof decks, walls, and crawl spaces throughout The Hammocks.
Foam is the right answer in The Hammocks when the ductwork is in the attic and the house is fighting humidity, and the wrong answer when the roof is near the end of its life. We will tell you which situation you are in before we quote it. Spraying foam to the underside of a roof deck that needs replacing in three years is an expensive way to make a future re-roof harder, and no honest Miami-Dade County contractor should sell it.
Spray foam is the only insulation on this list that stops air movement and heat transfer at the same time. In The Hammocks, that matters more than the R-value on the label. A Miami-Dade 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 Hammocks sits in Florida Climate Zone 1 — the hottest, most humid zone in the continental United States. Under the Florida Building Code, Energy Conservation (8th Edition), the ceiling minimum here is R-30 and framed walls are R-13. ENERGY STAR recommends R-30 for an uninsulated attic in this zone; we build to R-38 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 The Hammocks 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 The Hammocks home usually lands between $6,000 and $13,000; open-cell on the same deck is meaningfully less.

The Hammocks sits in Florida Climate Zone 1 — the hottest, most humid zone in the continental United States. The Florida Building Code, Energy Conservation (8th Edition) sets a R-30 minimum for ceilings in this zone, and R-38 is the practical target for comfort and utility savings. Many The Hammocks homes built before 2005 still measure R-11 to R-19, which is a large part of why their summer bills run high.

Standard Insulation does not administer utility programs, but we supply the itemized invoice and R-value documentation these applications ask for.
Insulation-only retrofits in Miami-Dade County usually do not require a permit, but new construction, additions and commercial work do, and the requirement is set locally rather than statewide.
