Four layers of the Crimson Shield.
Every Cardinal install is a layered defense system — engineered to the home, not the budget. We remove the barrier between comfort and cost.
Closed-Cell Spray Foam
R-6.5+ per inch. Structural reinforcement, moisture barrier, and an airtight seal engineered for Florida's humidity.
Open-Cell Foam
Expansive coverage and sound dampening for whole-home attics and wall cavities — breathable where it matters.
Radiant Barriers
Reflect up to 97% of radiant heat gain. The single highest-ROI upgrade for South Florida attics.
Thermal Diagnostics
FLIR infrared inspection maps every leak before and after install. Proof, not promises.
The territory is the evidence.
Hover any home to toggle the thermal layer — see the heat leaking out, then the Crimson Shield sealed in.

A different category
of contractor.
We don't compete on price. We compete on the 15-point standard the industry skips — from FLIR thermal imaging to Building Scientist verification. Here's where the barrier falls.
No competitor named. The standards speak for themselves.
67 counties sounds impressive.
Until your attic hits 145°F.
A statewide company lists every county on a page. But when your AC is running overtime and your upstairs won't cool, you don't need a crew driving three hours from Fort Myers — you need the local team that sealed your neighbor's attic last week. We don't spread across Florida. We own the Boca–Delray–Boynton corridor, and that depth is why our installs outperform.
Our crew lives in the corridor — not dispatched from Fort Myers, Naples, or Orlando.
Every ZIP, every neighborhood, every building code — we know it because we install in it weekly.
A statewide company schedules you next week. We can be in your attic tomorrow morning.
No rotating crews from whatever county is closest. The same Cardinal team every visit.
The corridor crew, not the state map.
When a statewide company sends a sub from two counties over, they don't know your neighborhood's venting quirks or your roof's heat load. We do — because we're already here.
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.
The codes that govern blown-in insulation in Boca Raton.
Every blown-in attic retrofit in Boca Raton is governed by the Florida Building Code and the IECC climate zone 2A requirements. Here are the specific provisions — and how Cardinal installs to them.
Minimum R-30 attic insulation
Florida Building Code sets a minimum of R-30 for attic insulation in climate zone 2A. Cardinal installs to R-38–R-49 on retrofits — above code minimum, matched to Boca's long cooling season and DOE guidance (R-49–R-60 for zone 2A).
Air-sealing the thermal envelope
The code requires the building thermal envelope to be sealed. Blown-in insulation alone does not meet this — every penetration in the attic floor (can lights, plumbing, hatch, duct chases) must be sealed before insulation goes in. This is the step most contractors skip and the one the code demands.
Soffit & vent clearance (baffles)
Code requires minimum 1 inch of clearance between insulation and roof sheathing at eaves, and that intake ventilation not be obstructed. Baffles at every soffit vent keep blown-in material from choking off intake air — a code compliance item, not an upgrade.
Vapor retarder & moisture control
In Boca's hot-humid climate zone, the code addresses moisture drive. For coastal attics, closed-cell foam acts as a Class II vapor retarder; blown-in cellulose/fiberglass must sit on a sealed ceiling plane so humid air cannot condense on the cool drywall above living space.
Verify the code yourself
These are the official sources Cardinal installs to. A real contractor names the code; a marketer names a price.
The air purifiers a sealed South Florida home needs.
Once Cardinal seals your attic and air-seals the envelope, your home holds conditioned air in — which means whatever is generated indoors stays indoors too. A true-HEPA air purifier is the complement to a sealed envelope: it cleans the air the seal is now holding. We don't sell these — we recommend them because a sealed home needs filtered air.
Coway Airmega 200M
True HEPA, quiet, energy-efficient, and proven in long-term independent testing. The right size for a master bedroom or living room in a sealed Boca ranch.
- True HEPA + carbon pre-filter
- Lowest noise at speed 1
- 8W on low — runs 24/7 cheaply
Levoit Core 300
True HEPA at half the cost of the Coway, compact, and effective in a single bedroom or home office. The budget pick that actually performs.
- True HEPA + carbon filter
- Compact and quiet
- Affordable replacement filters
Blueair Blue Pure 211+
High CADR for open-concept living areas and the large second-floor volumes common in Boca's two-story estates. Washable pre-filter extends HEPA life.
- High CADR for large spaces
- Washable pre-filter
- Handles pet and cooking odors
Honeywell HPA300
Rugged, high-output HEPA that handles South Florida humidity and larger particles (dust, pollen, dander) well. The workhorse pick for a sealed home with pets.
- True HEPA, high output
- Durable long-term build
- Effective on pet dander and pollen
How to choose an air purifier for a sealed Florida home
- Look for true HEPA. "HEPA-type" is not HEPA. True HEPA captures 99.97% of 0.3-micron particles — the standard that matters for pollen, dust, and dander.
- Match CADR to room size. Clean Air Delivery Rate should be at least two-thirds of the room's square footage. Undersized units don't clean — they just hum.
- A carbon pre-filter matters in Florida. It captures odors and VOCs from cooking and cleaning — the stuff a sealed home holds onto.
- An air purifier is not a dehumidifier. In South Florida, humidity control is still your AC's job. A purifier cleans particles; it does not remove moisture.
- Run it 24/7 on low. HEPA purifiers are most effective on the lowest quiet setting running constantly, not on high intermittently.
Cardinal Insulation does not sell air purifiers and has no affiliate relationship with any manufacturer. These are independent recommendations based on independent testing (AHAM Verifide CADR ratings) and field experience in sealed South Florida homes. Always verify current model availability and CADR ratings on the manufacturer's site before buying.

Real prices. No phone call required.
Most insulation companies hide their pricing and make you call. Cardinal publishes it. Tell us your project and square footage — get a tailored price range, your cooling savings, and your payback period in 60 seconds.
Range is within ~10–15% of final quote, confirmed at your free FLIR inspection. No obligation.
Or call (561) 654-7698Free upfront quotes. No lowball games.
We give you a transparent, itemized quote before a single bag of insulation moves — and we prove the work with attic rulers and before/after photos. Beware of cheap quotes from companies that skip the steps that actually make insulation perform.
Transparent, free upfront quotes
You get an itemized quote in writing before we start — every zone, every material, every line item. No hidden fees, no "we'll figure it out when we get there," no surprise add-ons after the crew shows up. The number you see is the number you pay.
Beware of cheap quotes
A low quote usually means skipped steps: no air sealing of top plates, shallow blown-in depth, and no proof of install. You pay less up front — and pay again in higher cooling bills and a job that never hit R-30. The cheap quote is the expensive one.
- • Skipped top-plate air sealing = leaks remain
- • Shallow depth = no R-30 = no savings
- • No photos = no proof the job was done
How we verify every blown-in install
Attic rulers
We install printed depth rulers in the attic and photograph them so you can see the blown-in insulation measures a true 10–12 inches — the depth required for R-30 in South Florida.
Before & after photos
You get dated before-and-after photos of your attic — the bare joists, then the full 10–12" depth. No "trust us." You see the install with your own eyes.
Top-plate air sealing
Before any insulation goes in, we air-seal every top plate and penetration. This is the step cheap quotes skip — and it's the difference between insulation that performs and insulation that just sits there.
10–12 inches = R-30. That's the Florida code depth for blown-in attic insulation — and we prove it with rulers and photos on every job.
We put the risk on us, not you.
The barrier between you and comfort shouldn't be money or trust. We remove both — with financing, a lifetime warranty, and proof you can see.
Lifetime Workmanship Warranty
Every seal we install is guaranteed for the life of the home. If it ever fails, we fix it free — no fine print.
Flexible Financing
Spread the cost over 12–60 months with low-interest options. Most homeowners pay less per month than they save on cooling.
Same-Week Inspection

Documented Savings
Before-and-after infrared proof. You see the sealed shield in thermal imaging before you ever pay the balance.
