Insulation in Delray Beach, FL
Cardinal Insulation is based in Boca Raton and runs crews daily in Delray Beach. We upgrade hot attics in Downtown Delray, Pineapple Grove, Lake Ida, Tropic Isle, Kings Point, Seven Bridges, and Delray Trails.
Same crew, same-week inspections, no subcontractors. The humidity and attic heat along Atlantic Ave, Military Trail, and Congress are exactly what our insulation is built for.
Delray holds two very different housing stocks — 1920s bungalows near Pineapple Grove and the historic district, and two-story estates west of Military Trail. Older homes need air sealing before depth; the newer builds mainly need attic depth. We quote them differently.

Serving Delray Beach, Florida.
Delray Beach runs from historic downtown bungalows along Atlantic Avenue to Intracoastal homes and west-side estates. We retrofit both with blown-in attic insulation, spray foam, and moisture-ready air sealing in ZIPs 33444–33484.
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.

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.

The climate math for Delray Beach.
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.
Delray Beach sits in the hottest, most humid stretch of South Florida's Atlantic coast — IECC Zone 1, hot-humid. NOAA normals show summer highs near 90°F with afternoon humidity above 78%. The DOE flags the attic floor as the single highest-ROI insulation surface in this zone; Florida Building Code requires R-30, and ENERGY STAR recommends R-38 for the cooling-dominated 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.
Yes. We serve all of Delray Beach — from downtown and Atlantic Ave to Pineapple Grove, Lake Ida, Tropic Isle, Kings Point, and the Military Trail / Congress corridors. The humidity and attic heat along the coast are exactly what our blown-in and spray foam packages are built for.
Yes. Older Delray homes leak air through plank sheathing and unsealed top plates before insulation even matters, so we air seal first and then blow cellulose or fiberglass to R-38. We work around original plaster, older wiring runs, and low attic clearances.
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.
