Built for West Palm Beach's historic homes and urban heat.
West Palm Beach is a different insulation problem than the western suburbs. The city's core — El Cid, Flamingo Park, Old Northwood, Grandview Heights, and Mango Promenade — is dense with 1920s–40s homes that were built with little to no attic insulation and original plaster walls that can't be disturbed. Downtown towers around CityPlace sit under a measurable urban heat-island effect. And the intracoastal waterfront in Southend and El Cid carries salt-air humidity straight into under-insulated attics.
Blown-in insulation is the cleanest answer for that mix. It fills the irregular, hard-to-reach rooflines of historic bungalows without touching original plaster or trim — a minimal-invasion retrofit that Flamingo Park and Old Northwood homeowners specifically request. It's the lowest installed cost per R-value of any insulation, which matters when a 100-year-old attic needs a full blow from scratch. And moisture-resistant fiberglass blown-in stands up to the intracoastal humidity that would degrade lesser material.
What we install in West Palm Beach attics
- Blown-in fiberglass to a uniform R-38 depth — our default for West Palm Beach's humid, intracoastal-exposed 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 West Palm Beach difference
Every West Palm 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 West Palm Beach homeowners recover the cost in 3–5 years on FPL savings alone.

Move the sliders to match your West Palm Beach attic. We model annual conductive heat gain through your ceiling and convert it to real FPL cooling dollars — comparing your current attic, standard fiberglass batt, and Cardinal's blown-in R-38.
Model uses South Florida cooling-degree-hours, SEER-14 AC efficiency, and FPL's ~$0.14/kWh rate. Actual savings vary with duct leakage, radiant gain, and occupancy.

The questions Boca, Delray & Boynton actually ask.
Blown-in attic insulation in West Palm Beach typically runs $1,500–$4,200 depending on square footage, target R-value, and whether we're topping up or starting fresh. Historic homes in El Cid, Flamingo Park, and Old Northwood often need a full blow because they have little to no original insulation. Get an instant itemized quote by ZIP code (33401, 33405, 33407) — no call required.

It's the ideal retrofit for West Palm Beach's 1920s–40s historic homes. Blown-in fills irregular, hard-to-reach rooflines without disturbing original plaster and trim — a minimal-invasion upgrade that Flamingo Park and Old Northwood homeowners specifically request. We verify coverage with FLIR so nothing is left to guesswork.
Fiberglass blown-in is our default for West Palm Beach — it's moisture-resistant and settles less, which matters in intracoastal neighborhoods like El Cid and Southend 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 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 West Palm 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% — the average reduction we document across sealed Palm Beach County homes.
Same-week. We keep a dedicated Palm Beach County crew, so most West Palm 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 West Palm Beach's cooling load and urban heat-island 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.
