Built for Delray Beach's historic bungalows and intracoastal homes.
Delray Beach is a tale of two housing stocks. The east — Delray Beach Waterfront, Tropic Isle, and the Lake Ida and Pineapple Grove historic districts — is dense with 1920s–40s bungalows built with little to no attic insulation and original plaster that can't be disturbed. The intracoastal and oceanfront stretches carry salt-air humidity straight into under-insulated attics. West and inland — Delray Beach Estates, Berkshire Gardens, Rainberry Bay — mid-century block homes and active-adult communities run the AC nonstop on degraded or absent insulation.
Blown-in insulation is the cleanest answer for both. It fills the irregular, hard-to-reach rooflines of historic bungalows without touching original plaster or trim — a minimal-invasion retrofit that Lake Ida and Pineapple Grove homeowners specifically request. It's the lowest installed cost per R-value of any insulation, which matters when a 100-year-old Delray Beach attic needs a full blow from scratch. And moisture-resistant fiberglass blown-in stands up to the oceanfront and intracoastal humidity that would degrade lesser material.
What we install in Delray Beach attics
- Blown-in fiberglass (Owens Corning ProPink L77) to a uniform R-38 depth — our default for Delray Beach's humid attics.
- Blown-in cellulose where density and fire resistance matter more than moisture — recommended per home after a FLIR inspection.
- Attic top-ups to bring compressed or under-filled attics up to Florida code R-30 to R-38.
- Air-sealing first — we seal penetrations before we blow, so the insulation actually performs at its rated R-value.
The Delray Beach difference
Every Delray Beach blown-in job starts with a free FLIR thermal inspection and ends with a post-install infrared proof report — you see the sealed coverage in thermal imaging before you ever pay the balance. We run a 10-point inspection the industry skips, we keep a dedicated Palm Beach County crew so scheduling lands same-week, and every install carries a lifetime workmanship warranty. Most Delray Beach homeowners recover the cost in 3–5 years on FPL savings alone.

The right R-value for a Boca Raton attic.
Florida code requires R-30 minimum, but we recommend R-38 for Boca Raton's cooling load and intracoastal sun exposure. We blow to a uniform depth and measure at multiple points so you have proof your attic meets or exceeds code.
| R-Value | Tier | Fiberglass depth | Cellulose depth | Boca Raton context |
|---|---|---|---|---|
| R-30 | Florida code minimum | 11" | 8.5" | Meets Florida Building Code for attic insulation — the baseline for Boca Raton homes. |
| R-38 | Recommended for Boca Raton | 14" | 11" | Our standard blow for Boca's cooling load and intracoastal sun exposure. Best ROI tier. |
| R-49 | Premium / deep attic | 18" | 14" | For Boca country-club homes with deep attic volumes chasing maximum efficiency. |
Depth verified
We measure blown-in depth at multiple points across the attic — not a visual guess.
FLIR proof
Post-install infrared scan confirms uniform coverage before you pay the balance.
Over-spec'd for settling
We over-spec depth to absorb any settling so your R-value holds for the life of the home.
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.

Air leaks, noise, and energy bills.
The three questions every Delray Beach homeowner asks before investing in blown-in attic insulation — answered straight, with the science behind each.
Blown-in insulation resists air movement but does not fully stop it — it filters air, it doesn't seal it. That's why Cardinal air-seals every top plate, wiring penetration, and plumbing chase with foam before any insulation goes in. Skipping that step (which cheap quotes do) lets conditioned air leak past the insulation and wastes the R-value you just paid for. In Delray Beach's humid climate, unsealed air leaks also carry moisture into the attic, which can compress insulation and grow mold. Our free FLIR inspection maps every leak before we blow a single bag.
Blown-in attic insulation noticeably reduces exterior and between-floor noise — typically 5–8 decibels of airborne sound transmission, which the ear perceives as roughly half as loud. Cellulose outperforms fiberglass here because its higher density absorbs more sound energy. Delray Beach homeowners near I-95, Federal Highway, or flight paths report a clear difference after a blown-in top-up. It won't eliminate impact noise (footsteps, slamming doors) — that requires wall cavity insulation — but it meaningfully quiets road traffic, lawn equipment, and neighbor activity.
Topping an under-insulated attic to R-38 typically cuts cooling costs 15–25% in South Florida homes. The exact savings depend on your attic's current R-value, A/C efficiency, and duct location. If your ducts run through the attic (common in Delray Beach homes built 1970–2010), the savings can be higher because the ducts now sit in a cooler space. We document the expected savings in your itemized quote and verify the install with a post-install FLIR scan so you can see the thermal difference before you pay the balance.
South Florida's climate means your A/C runs 8–10 months a year, pulling conditioned air up into the attic through every unsealed gap. Insulation without air sealing is like wearing a sweater with the zipper open — it slows heat but doesn't stop the air carrying it. In Delray Beach's humidity, those same air leaks carry water vapor that can condense in the attic, wet the insulation, and grow mold. Cardinal seals every penetration first, then blows — the order matters, and it's the step that makes the R-value actually perform.
Yes, indirectly. The added density in the attic dampens low-frequency exterior noise — wind-driven rain on the roof, thunder, and distant storm activity all register quieter after a blown-in top-up. It does not structurally reinforce the roof (only closed-cell spray foam does that), but the sound-dampening effect is a consistent benefit Delray Beach homeowners mention after installation. If storm resilience is a priority, ask about pairing blown-in with a radiant barrier or spray foam on the roof deck.
Delray Beach homes lose the most cooling energy through the attic — the sun bakes the roof deck to 150°F+, and that heat radiates into your living space. Blown-in R-38 insulation creates a thick thermal blanket on the attic floor that slows that heat transfer, so your A/C runs less, cycles shorter, and lasts longer. The Department of Energy estimates proper attic insulation saves 15–30% on cooling costs in hot-humid climates like South Florida. We verify the improvement with before-and-after FLIR thermal imaging on every install.

We blow attic insulation across every Delray Beach neighborhood — Lake Ida, Pineapple Grove, Delray Beach Waterfront, Tropic Isle, Berkshire Gardens, Rainberry Bay, Delray Beach Estates, Ibis Cove — and every ZIP from 33444 to 33446. Same-week scheduling with a local crew, never subcontracted.
Yes. Blown-in is ideal for Delray Beach's historic bungalows and intracoastal homes — it fills irregular rooflines and gaps that batts miss, and we verify coverage with FLIR so nothing is left to guesswork. The install carries a lifetime workmanship warranty.
Fiberglass blown-in (Owens Corning ProPink L77) is our default for Delray Beach — it's moisture-resistant and settles less, which matters where humidity runs high. Cellulose is denser and more fire-resistant but can hold moisture. We recommend per home after a free FLIR inspection.
Yes. Blown-in is ideal for topping up compressed or under-filled Delray Beach attics to meet Florida code R-30 to R-38. We inspect first with FLIR to confirm the existing material is clean and dry before adding depth — we never blow over contaminated or wet insulation.
Properly installed blown-in fiberglass lasts 80+ years with minimal settling, even in South Florida humidity. We over-spec depth to account for any settling, so your R-value stays at code for the life of the home. Cellulose can settle up to 20% over time and may need a top-up down the road.
Yes. Topping an under-insulated Delray Beach attic to R-38 typically cuts cooling costs 15–25%. Pair it with a radiant barrier for the full Cardinal Shield and savings up to 37%.
Same-week. We keep a dedicated local crew, so most Delray Beach blown-in installs land on your calendar within 3–5 days — often faster. Most single-family attics are completed in a single day.
Only when needed. If your existing attic insulation is water-damaged, compressed, moldy, or rodent-contaminated, we remove it under negative-pressure containment first — then blow in clean material. Clean, dry, intact insulation can be topped up. A free FLIR inspection tells you which you need.
Florida code requires R-30 minimum, but we recommend R-38 for Delray Beach's cooling load and sun exposure. We blow to a uniform R-38 depth and document the depth at multiple points so you have proof your attic meets or exceeds code. R-49 is available for deep attics chasing maximum efficiency.
