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.

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.
Boca Raton's Atlantic-coast position drives a hot-humid climate classified as IECC Zone 1. Summer dew points routinely exceed 70°F, pushing attic heat gain and moisture load to the top of the building envelope. The Florida Building Code sets a ceiling minimum of R-30; the U.S. Department of Energy and ENERGY STAR both recommend R-38 for this zone because the cooling load dominates year-round.

What Boca Raton homeowners say.
"Cardinal found heat leaks two other companies missed. The thermal report after install showed a sealed attic. Cooling bill dropped 38%."
"We built new in Boca Bridges and Cardinal spec'd the insulation package before drywall. The attic stays within 8° of the house — our AC barely runs now."
"The crew sealed our Woodfield country-club home and the FLIR proof report showed every gap closed. Second floor finally matches the ground floor temperature."

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.
Yes. We serve all of Boca Raton — including West Boca, Sandalfoot, Loggers Run, and the Glades Road corridor, plus East Boca, Mizner Park, and Boca Pointe. Same local crew, same-week scheduling.
Usually yes. Homes from that era were insulated to R-11 or R-19, and the material has compressed over decades. Air sealing plus a blown-in top-up to R-38 is the highest-return upgrade for those attics, and we document the before-and-after with FLIR thermal imaging.
Yes. The instant quote by ZIP code is free with no obligation. If you want a FLIR thermal inspection, that's free too — we document every attic before we recommend anything.
