The attic numbers, not a brochure

The 2023 Florida Building Code, Energy Conservation, Table R402.1.2 sets a climate zone 1 ceiling at R-30 and a climate zone 2 ceiling at R-38. Cardinal installs R-38 and checks the inches. A Florida page that lists R-49 to R-60, or R-3.2 to R-3.8 per inch for both fiberglass and cellulose, is using a different book. Table R402.4.1.1 says air-permeable insulation shall not be used as the air seal.

Quotes are prepared by Russell Y, a building scientist, BPI certified, and certified to perform blower door testing. When the door is run, the result is air changes per hour at 50 pascals, the method in R402.4.1.2. That section limits new houses in climate zones 1 and 2 to 7 ACH50. An insulation job on an existing house is not automatically that test. We report the number only when we measured it.

Insulation numbers Cardinal uses against the Florida code
Item	Number	What it means
Zone 1 ceiling, Florida code	R-30 minimum	Palm Beach and Broward
Zone 2 ceiling, Florida code	R-38 minimum	Not R-49 and not R-60
What Cardinal installs	R-38, depth checked	Above the zone 1 floor
New blown fiberglass	About R-2.5 per inch	Not R-3.2 to R-3.8
Settled fiberglass	About R-2.2 per inch	4 inches is about R-9
New cellulose	About R-3.6 per inch	Denser. Still not an air seal
Open-cell foam	About R-3.6 per inch	A roof-deck product
Closed-cell foam	About R-6.5 per inch	2 inches is about R-13

Loose fill does not stop air. The holes are sealed first. Two inches of closed-cell foam is an air-seal coat, not a finished attic. We do not quote a dollar amount off the power bill. Ducts in a vented attic stay in the heat. The shop for the Boca listing is 4263 NW 1st Ave.
