What has to come out

Royal Palm Beach is production housing next to Wellington. The original install often stopped at the code floor. It comes out when a leak or rodents ruined it, including the strips over the outside walls where the soffit air washed the fill thin and a later stain sat.

What stays

Dry fill, even if it is only the original thickness, stays. Can lights that are not IC-rated are not buried, and they are not a reason to remove the whole attic. Non-IC cans keep their clearance.

Getting the bags out

There is no shop in the village. The drive is from Boca Raton. Tile roofs and screened patios do not change the bag path. The hatch does.

How the day goes

  1. Look

    The hatch in Royal Palm Beach gets opened before a truck is promised. Depth, moisture, and whether the mess is the whole attic or one bay.

  2. Protect

    The rooms under the hatch get covered. The bags stay on the path that was agreed. A plaster or wood lid that is already soft stops the day.

  3. Remove

    Ruined fill is vacuumed into bags and hauled off. The deck should be visible where the bad fill was. Dry fill next to it is not taken just to make the attic look empty.

  4. Next

    Sanitizing only if the insulation was contaminated. Then the holes that are finally visible get sealed. Then new insulation to R-38. Those are not one price.

After the deck is bare

A game room over the garage is foam, with those vents closed. It is not vacuumed with the main attic unless that room was also blown and is now wet. Two prices, one roof, if both are in the scope. Call (561) 654-7698.

The install that follows is blown-in insulation in Royal Palm Beach. Contaminated decks are attic sanitizing, a separate page. The contractor, separate from this tear-out, is the insulation contractor in Royal Palm Beach.

Measured against the Florida code

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.

The attics on this page

Royal Palm Beach is production housing next to Wellington. Tile roofs, screened patios, and attics that were filled to the code minimum when the house was built. The minimum then, and the zone 1 minimum now, is not the same as a deep, even R-38.

The settled layer is the problem, not the tile. Can lights and top plates get sealed. Non-IC cans do not get buried. Then the blow goes to R-38. There is no shop in the village. The drive is from Boca Raton.

A game room over the garage is foam, and the vents over that room have to be closed. The main attic is not that room. If both are hot, they are two prices on one roof.

The code in Royal Palm Beach

Royal Palm Beach is in Palm Beach County. Table R301.1 of the 2023 Florida Building Code, Energy Conservation, lists Palm Beach County as climate zone 1A. Table R402.1.2 sets the zone 1 ceiling minimum at R-30. Royal Palm Beach does not publish its own attic R-value. The city enforces the Florida Building Code.

Palm Beach County is not in the High-Velocity Hurricane Zone. That zone is only Miami-Dade and Broward. Parts of the Palm Beach coast are still a wind-borne debris region, which is an opening-protection rule from the wind map, not an insulation number. Section R806.2 of the 2023 Florida Building Code, Residential, sets the net free vent area at 1/150 of the attic. The exception is 1/300 only when 40 to 50 percent of that area is within 3 feet of the ridge and the rest is in the bottom third. Insulation cannot close the soffit. R806.3 requires at least 1 inch at the eave vent.

The county zone is Table R301.1. The Boca Raton worked example, including the vent math, is the building code page. Cardinal still installs a vented attic to R-38 and checks the depth.
