Which areas does Cardinal Insulation serve?

We serve Boca Raton, Delray Beach, and Boynton Beach, FL — the entire tri-city corridor from the Boca inlet to Boynton's western estates.

How is Cardinal different from other insulation companies?

We run a 10-point inspection the industry skips, use local crews, quote same day, and back every seal with a lifetime workmanship warranty with FLIR proof reports.

Will spray foam lower my FPL bill?

Yes. Our sealed homes average a 37% cooling-cost reduction. Closed-cell foam plus a radiant barrier reflects up to 97% of radiant heat gain.

How fast can you inspect my home?

Same-week — usually within 3–5 days, often faster. Use the Schedule Inspection button to grab a real-time slot.

Do you work on new construction and existing homes?

Both. We engineer thermal packages for new builds and retrofit existing homes across Boca, Delray, and Boynton.

Is spray foam safe for Florida humidity and coastal homes?

Yes. Closed-cell foam acts as a moisture barrier and structural reinforcement, ideal for salt-air coastal environments.

Radiant Barriers for Boca Raton Properties

radiant barriers is the workhorse of Florida attic retrofits. For Boca Raton properties, this is frequently the right specification — but we will tell you plainly when it is not, and when a less expensive approach delivers the same outcome.

Boca Raton sits in South Florida, where the recommended attic target is R-38 to R-49. That number, along with where your ductwork runs and what condition the existing assembly is in, is what determines the right specification for your property.

Types and Methods

Foil-faced radiant barrier

A double-sided reflective foil installed across the underside of the roof deck. It reflects up to 97% of radiant heat gain, stopping the attic from hitting 140°+ and slashing the cooling load on your ceiling insulation. This is our standard for South Florida attics.

Reflective insulation with bubble layer

A layered product combining reflective foil with a bubble core, used where an air gap and a radiant barrier are needed together. It adds a small R-value in addition to the reflective properties, useful in metal buildings and cathedral ceilings.

A radiant barrier needs an air gap between the foil and the heat source to work — without it, the heat conducts straight through. We verify the installation method maintains the required air gap and that the roof has no active leaks.

Benefits for Boca Raton Property Owners

Reflects up to 97% of radiant heat — the dominant heat source in FL attics.
Can lower attic temps by 20–35°F on peak summer days.
Lowest cost-per-saved-BTU insulation upgrade available.
Pairs with spray foam for a layered Crimson Shield defense.
No degradation — reflective foil lasts indefinitely.

Best Applications

Existing vented attics with ductwork in the attic
Homes with high cooling bills and 140°+ attic temperatures
Paired with blown-in or spray foam for layered defense
West-facing roofs that bake all afternoon
New construction roof decks

How We Install It in Boca Raton

1FLIR-scan the attic to document the existing thermal profile
2Measure the roof deck area and calculate material needed
3Cut foil to span between rafters, foil-facing down toward the attic
4Staple or nail the foil to the bottom edge of each rafter
5Maintain a minimum air gap between the foil and the roof deck
6Seal all seams with foil tape to create a continuous reflective surface
7FLIR-scan to verify the temperature drop and document the improvement

FAQs

Radiant Barriers FAQs — Boca Raton

Radiant barriers are the most affordable high-impact upgrade — typically $1,200–$3,500 for a whole attic. Most tri-city homeowners recover the cost in under two cooling seasons on FPL savings alone.

Dramatically. Florida attics hit 140°+ from radiant heat gain. A radiant barrier reflects up to 97% of that radiation, dropping attic temps 20–35°F and reducing the load on your AC — the single highest-ROI upgrade for a South Florida attic.

Yes — we install radiant barrier foil across the underside of the roof deck, above existing insulation. It works alongside spray foam or fiberglass without conflict, and we verify placement with FLIR imaging.
