Blown-in insulation in West Palm Beach.
Cardinal blows fiberglass or cellulose across the attic floor and stops at R-38. Florida’s code floor is R-30. A lot of houses in 33401, 33405, 33407, and 33409 are still sitting on a few inches of settled batts.

The attic is why the AC never catches up.
West Palm Beach spends most of the year with the sun on the roof and the air conditioner trying to keep the ceiling from radiating that heat back down. Three or four inches of yellow batts — about R-7 to R-9 once they settle — is not an R-30 attic. It just looks like “there’s insulation up there.”
Blown-in fill covers the joists and the gaps batts leave at the edges, the wires, and the weird corners by the bath fan. It is a top-up when the old material is dry. It is a removal first when the old material is wet.
- 01Settled batts under the joists, hot bedrooms on the west side.
- 02Eaves with no baffles, so the last foot of ceiling has nothing on it.
- 03A hatch with no weatherstrip, leaking air straight into the hall.
What a West Palm Beach blown-in job includes.
The hose is the visible part. The part that changes the bill is the sealing and the depth. See the install, step by step.
Air seal
Penetrations, top plates, chases, and the hatch, before any insulation is opened.
Baffles
Soffit vents stay open. We do not choke the intake to pile the fill higher.
The blow
Fiberglass or cellulose to a marked R-38 across the attic floor.
The hatch
Weatherstrip plus a foam panel on the back, so the hole is not the weak spot.
Clearances
Flues, non-IC cans, and bath fans stay dammed. We do not bury them.
Depth marks
You can read the finished depth on a truss without taking our word for it.
Two materials. One target.
Blown fiberglass lands around R-2.5 per inch. It is the default in a Palm Beach attic that might see a roof leak, because it does not hold water the way cellulose can. The white blanket in the photo up top is that material.
Blown cellulose lands around R-3.5 per inch. Historic houses with low tie lines sometimes need the extra R per inch so R-38 fits without burying the structure. We do not pick it for a wet deck. A wet deck is a removal first.
Cost in West Palm Beach moves with square footage and what is already up there, not with a script that always sells the same bag.
Neighborhoods we actually blow.
All West Palm Beach neighborhoods- El Cid33401Historic Mediterranean. Low attics, clay tile, tight hatches. We baffle the eaves before we blow.
- Flamingo Park33401, 33405Bungalows and shallow attics. A dry top-up is usually one day.
- Old Northwood33407Cottages with knee walls and dormers. The slope and the floor both need coverage.
- Grandview Heights33407Wood frame, small hatches, original wiring penetrations.
- South End33405Howard Park, Prospect Park, and the blocks toward Southern.
- Downtown and Rosemary Square33401Towers do not have attics. The work is the older houses on the edge of downtown.
- Belvedere and Westgate33409Postwar ranches. Big open attics, usually the fastest blow in the city.
- Western West Palm33415Larger roofs toward Haverhill and Okeechobee. Additions often have their own attic.
Tell us the attic. We’ll show the gap to R-38.
Square footage, what’s up there now, fiberglass or cellulose. The planner gives inches to add, cubic feet, and a dollar range in the band Cardinal already publishes. It is not a bid. The bid is after we see the hatch, or clear photos of it.

Straight answers
The long version, with the same questions written out for search, is on the blown-in insulation FAQ.
What number do I call for blown-in insulation in West Palm Beach?
Call Cardinal Insulation at (561) 654-7698. The shop is 4263 NW 1st Ave, Boca Raton, FL 33431. Ask for a West Palm Beach attic and name the neighborhood, or the ZIP if that is all you have. El Cid, Flamingo Park, Northwood, Grandview Heights, and the ranches west of I-95 are all on this crew.
What R-value do you install in West Palm Beach?
Florida’s energy code sets a floor around R-30 for these attics. Cardinal installs blown-in insulation to R-38, above that floor. The planner on this site uses R-38 as the target. A depth mark on a truss is how you check the crew actually got there.
Fiberglass or cellulose?
Both. Fiberglass is lighter and handles a roof leak better, which matters in a humid county. Cellulose packs more R-value per inch, so a low attic sometimes needs it to hit R-38 without burying the truss ties. We pick after we see the hatch, not from a script.
How much does blown-in insulation cost in West Palm Beach?
Most attic top-ups land between $1,500 and $4,000. The number moves with attic square footage, how much fill is already there, and whether the old material has to come out. The planner scales a published Cardinal example — 1,800 sq ft with 4 inches of settled fiberglass, about $2,100 to $3,350. It is a planning range, not a bid.
