Serving Fort Lauderdale, Florida.
Fort Lauderdale runs through Rio Vista, Victoria Park, Coral Ridge, and the Las Olas Isles, where salt-air humidity meets hot attics. Blown-in attic insulation, spray foam, and air sealing across ZIPs 33301–33316.
Installed to the standards the government sets.
Every Cardinal blown-in install is specified to the guidance issued by the U.S. Department of Energy, ENERGY STAR, and the Florida Building Commission — the three bodies that define how a South Florida attic should be insulated. We don't guess at R-value. We install to code, document it, and prove it in thermal imaging.
R-30 to R-60 for South Florida attics
The DOE recommends R-30 to R-60 of attic insulation for homes in DOE Climate Zone 1 (South Florida), noting that proper insulation is one of the most cost-effective ways to improve energy efficiency and comfort. Cardinal blows to R-38 — the midpoint of the DOE's recommended range for our climate.
DOE — Blown-In & Loose-Fill InsulationUp to 15% savings on heating & cooling
ENERGY STAR recommends R-30 to R-60 for Florida attics and reports that sealing air leaks and adding insulation can save homeowners up to 15% on heating and cooling costs — and up to 37% when paired with a radiant barrier in South Florida's climate. Cardinal air-seals before every blow so insulation performs at its rated R-value.
ENERGY STAR — Seal & InsulateR-30 ceiling minimum in the Florida Building Code
The Florida Building Commission administers the Florida Building Code, which sets a minimum ceiling insulation value of R-30 for residential construction in South Florida. Cardinal installs to or above code on every job — and documents compliance with a depth-measurement and FLIR proof report before you pay the balance.
Florida Building Commission — FBCThe Cardinal standard exceeds all three.
We air-seal before we blow, install to R-38 (above the R-30 code floor), document depth at multiple points, and deliver a FLIR thermal proof report — so you can see the install meets DOE, ENERGY STAR, and Florida Building Code guidance before you ever pay the balance.

The climate math for Fort Lauderdale.
Official NOAA normals, Florida Building Code, and U.S. Department of Energy guidance — the data behind every insulation spec we write for this city.
Code vs. Cardinal
We install to the DOE / ENERGY STAR recommendation — above Florida code — because the cooling load in Zone 1 makes the extra depth worth it.
Fort Lauderdale is recorded at the FLL NOAA station — among the warmest in the corridor with over 4,200 annual cooling degree days. IECC Zone 1 hot-humid. The DOE flags the attic as the dominant heat-gain surface; Florida Building Code requires R-30 in the ceiling and ENERGY STAR recommends R-38 for the cooling-only climate.
Source station: Fort Lauderdale, FL (NOAA COOP 08-3109 / FLL). Values are rounded from 1991–2020 U.S. Climate Normals and are representative of the station, not a single year.

The questions Boca, Delray & Boynton actually ask.
Pricing depends on your home's size and the scope of work. Blown-in attic top-ups are the most affordable option, while closed-cell spray foam costs more because it also acts as a moisture barrier. We give you an itemized quote by ZIP code — no phone tag — and most homeowners recover the cost in a few years on cooling savings.
Florida code calls for a minimum of R-30 in the ceiling. We blow to R-38 — above code — because South Florida's heat gain makes the extra depth worth it. We'll measure your existing depth for free and tell you exactly what you need.
Most blown-in attic top-ups are finished in a single day. Spray foam and larger whole-home retrofits can take one to two days. We protect your living space, clean up, and hand you a FLIR proof report before you pay the balance.
