Insulation Contractor in Palm Beach County, FL
Palm Beach County is Cardinal Insulation's home turf — from the Boca Raton inlet to the western equestrian acreage of Loxahatchee. We serve every city in the county with the same engineered envelope: closed-cell foam, radiant barriers, and FLIR-verified sealing that hold 72° against the South Florida sun.
Verified by a Building Scientist
Cardinal's insulation packages are specified and verified against building-science principles — not installed by guesswork. Every job carries a documented thermal proof report.
Building-Science Specified
Every insulation package is specified against building-science principles — conductive, convective, and radiant heat paths addressed in the correct order, not just more material.
FLIR Thermal Verification
A certified thermal-imaging protocol images the attic and ceiling plane before and after install. You see the documented proof the seal is real — not a claim.
R-Value & Depth Measured
Insulation depth is blown to land at the target R-value after settling, measured against Florida code and DOE guidance for IECC climate zone 2A — not estimated.
Specifications aligned with U.S. Department of Energy, ENERGY STAR®, and Florida Building Commission guidance for South Florida's hot-humid climate.
Installed to Florida code. Documented on every job.
Every Cardinal install in Palm Beach County is specified to the Florida Building Code and IECC Climate Zone 2A requirements for hot-humid construction. We don't guess at R-value or skip air-sealing — we install to code, document it, and prove it with a FLIR thermal report.
R-30 ceiling insulation minimum
Florida Building Code, ResidentialThe Florida Building Code sets a minimum ceiling insulation value of R-30 for residential construction in South Florida. Cardinal installs to R-38 — above the code floor — and documents the installed depth with attic rulers and before/after photos on every job.
IECC Climate Zone 2A — hot-humid
International Energy Conservation Code · Zone 2ASouth Florida sits in IECC Climate Zone 2A, a hot-humid zone with specific insulation, air-sealing, and moisture-management requirements. Cardinal specs every package to Zone 2A guidance — closed-cell foam where moisture control matters, air-sealing before insulation, and ventilation pressure testing.
Air-leakage (blower door) limits
Florida Building Code — Air LeakageThe Florida Building Code limits air leakage in new residential construction, verified by blower-door testing. Cardinal air-seals top plates, penetrations, and the attic hatch before any insulation goes in — then proves the reduction with before-and-after blower-door readings when testing is scoped.
Permit & inspection compliance
Florida Building Code — PermitsWhere a permit is required, Cardinal pulls it and schedules the inspection. We install to code, document compliance, and hand you a depth-measurement and FLIR proof report so the inspector — and you — can verify the work before the balance is due.
Code-compliant by design. Cardinal installs to or above Florida Building Code minimums on every Palm Beach County job — and hands you the documentation to prove it.

The questions Boca, Delray & Boynton actually ask.
Most Palm Beach County homes run $1,500–$9,500 depending on service type, square footage, and scope. Blown-in attic insulation is on the low end; closed-cell spray foam whole-home retrofits are on the high end. We give an itemized instant quote by ZIP code — no phone tag required.
We serve every city in Palm Beach County — Boca Raton, Delray Beach, Boynton Beach, West Palm Beach, Wellington, and Loxahatchee (including The Acreage). Each city has dedicated landing pages for every insulation service we offer.
Palm Beach County is in IECC climate zone 2A, where the recommended attic target is R-38 to R-49. Florida Building Code requires R-30 minimum, but we recommend R-38+ for South Florida's cooling load. With spray foam on the roof deck, the attic becomes conditioned space and the effective R-value jumps dramatically.
Same-week. We keep dedicated Palm Beach County crews, so we can usually get a FLIR thermal inspection on your calendar within 3–5 days — often faster.
