Insulation in Hollywood, FL
Cardinal Insulation is based in Boca Raton and runs crews south to Hollywood. We upgrade hot attics in Hollywood Lakes, Hollywood Beach, Emerald Hills, Harbor Islands, Hollywood Hills, West Lake, North Beach, and South Central Hollywood.
Same crew, same-week inspections, no subcontractors. The coastal humidity and attic heat along the Broadwalk, Hollywood Blvd, and US-1 are exactly what our insulation is built for.
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.

Blown-In Attic Insulation
Fiberglass or cellulose blown to a uniform R-38 depth across your attic floor — filling every gap batts miss. Most homes done in a day.
Learn moreSpray Foam Insulation
Closed-cell and open-cell spray foam that seals the attic, adds a moisture barrier, and brings attic temperatures within 8° of living space.
Learn moreInsulation Removal
Safe, dust-controlled removal of contaminated, compressed, or water-damaged attic insulation before we blow in fresh material.
Learn moreAir Sealing
We seal penetrations and leaks before insulating, so your insulation performs at its rated R-value instead of leaking conditioned air.

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.
Hollywood's beachfront-to-inland span sits in IECC Zone 1 hot-humid, with NOAA-recorded summer highs near 90°F and dew points above 74°F. The DOE identifies the attic floor as the priority insulation surface; Florida Building Code sets R-30 as the ceiling minimum and ENERGY STAR recommends R-38 for the cooling-dominated South Florida load.

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.
