Attic Insulation in Pensacola, FL

Attic insulation in Pensacola does its hardest work from May through September. On a summer afternoon, the roof soaks up sun and the attic below it can run far hotter than the 91.6F average July high listed in Wikipedia's normals for the city. That heat radiates down through thin insulation into the rooms below, and if the air handler and ducts sit up there, they work in it too. A good attic job cuts both problems: less heat reaching the ceiling, and ductwork that is either sealed and buried or brought inside a sealed attic.

Two ways to fix an attic

The first approach keeps the attic vented and treats the ceiling as the line between inside and outside. We seal the gaps in the ceiling, then blow cellulose or fiberglass across the attic floor to depth. It costs less and works well when the attic is open and the ducts are in decent shape.

The second approach seals the attic itself. Foam goes on the underside of the roof deck and the gable walls, the soffit and ridge vents are closed off as part of the design, and the attic becomes a semi-conditioned space. Ducts and the air handler then run in air much closer to room temperature. It costs more, and the HVAC system should be checked afterward, but in houses with a lot of ductwork in the attic it often makes the biggest difference. We look at your attic and price the option that fits, or both.

How much insulation the attic needs

OpenEI's IECC map places Escambia and Santa Rosa counties in Climate Zone 2A, and the Insulation Institute's summary of the 2023 Florida energy code lists R-38 for ceilings in Zone 2. The Department of Energy recommends more for existing homes: R-49 to R-60 for an uninsulated Zone 2 attic, or R-38 to R-49 added over 3 to 4 inches of old insulation. HomeGuide lists blown fiberglass at R-2.2 to R-2.9 per inch and cellulose at R-3.1 to R-3.8 per inch, so reaching those levels takes a deep layer. Many Pensacola attics we see have a few inches of old, matted fill.

The leaks we seal first

Air moves through loose insulation, so sealing comes before depth. The usual leaks are the same in most houses: holes around plumbing vents and wiring, open chases above soffits and dropped ceilings, gaps around recessed lights, the attic hatch or pull-down stairs, top plates of interior walls, and the boots where supply registers meet the ceiling drywall. In summer those gaps work in reverse of a cold climate: hot, humid attic air is pulled down into the house whenever the AC or a bath fan lowers the indoor pressure. Sealing them helps the AC control humidity as well as temperature.

Ducts in the attic

If the ducts stay in a vented attic, we look at their condition before we bury them. Torn duct jackets, disconnected runs and sweating supply lines are common in older Pensacola attics. Ducts that sweat in humid air can drip onto the insulation and ceiling below, and that water stain is easy to mistake for a roof leak. We point out what needs an HVAC contractor, and we keep air handler access clear.

Rebates and storm damage

FPL's Northwest Florida ceiling insulation page lists a $220 instant rebate for homes with less than R-8 in the ceiling, installed by an FPL-approved participating contractor after a home energy analysis. Check the current terms with FPL before planning around it. If the attic took on water from storm damage, the wet insulation should come out before new material goes in; we cover that on our removal page.
