How much does spray foam insulation cost in Boca Raton?

Most Boca Raton homes run $3,500–$9,500 depending on square footage and scope. We give an itemized instant quote by ZIP code, and most homeowners recover the cost in 3–5 years on cooling savings.

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.

Metal Building Insulation in Delray Beach, Florida

Metal buildings — barndominiums, workshops, warehouses, and commercial shells — face unique insulation challenges: condensation on metal surfaces, extreme radiant heat gain, and the need for insulation that adheres directly to the building envelope. Cardinal installs closed-cell spray foam for metal buildings across the corridor, adhering directly to the metal panels, acting as a vapor barrier, and bringing the envelope within 8° of living space.

Metal Building Insulation for Delray Beach Properties

metal building insulation is the workhorse of Florida attic retrofits. For Delray Beach 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.

Delray Beach 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

Closed-cell spray foam for metal buildings

Closed-cell foam adheres directly to the metal panels — no gaps, no settling, no sagging. It acts as a Class II vapor barrier, stopping the condensation that rusts metal and grows mold. It also adds structural rigidity to the panels and purlins, a real advantage in high-wind zones.

Fiberglass blanket for metal buildings

A traditional, lower-cost option — fiberglass blanket draped over the purlins before the metal panels go on. It delivers R-value but does not air-seal or stop condensation. We recommend it only for budget projects where condensation is not a concern.

Condensation is the #1 problem in uninsulated metal buildings — warm, humid air hits the cool metal surface and water drips from the ceiling. Closed-cell foam insulates the metal from the interior air and acts as a vapor barrier, stopping condensation at its source.

FAQs

Metal Building Insulation FAQs — Delray Beach

Closed-cell spray foam for a metal building runs $2.40–$4.90 per square foot installed depending on thickness, building size, and access. It's the highest-performance option for metal — adhering directly, acting as a vapor barrier, and stopping condensation. Get an instant itemized quote by ZIP code.

Closed-cell spray foam. It adheres directly to metal panels (no gaps), acts as a Class II vapor barrier (stops condensation), adds structural rigidity, and delivers R-6.5 per inch. Fiberglass batts in metal buildings sag, absorb moisture, and lose R-value — closed-cell foam doesn't.

Condensation forms when warm, humid air hits a cool metal surface. Closed-cell foam insulates the metal from the interior air and acts as a vapor barrier — so humid air can't reach the cool metal surface to condense. This stops the rust, mold, and dripping that plague uninsulated metal buildings in South Florida.
