R-38 Attic Insulation in Florida
Your attic hits well over 120 degrees on a summer afternoon. A thin, settled layer of old insulation is all that separates it from your ceiling. R-value measures how well insulation blocks heat, and higher is better. Upgrading to R-38 is the highest-return efficiency move most Florida homes can make.

What's included
What a done-right attic includes
Insulation performs only as well as the prep under it, so the scope is three things, in this order.
-
Air-sealing the ceiling plane
Closing the gaps around light fixtures, plumbing stacks, and top plates that leak conditioned air into the attic.
-
Blown insulation to R-38
Slows the transfer from the attic. The A/C runs shorter cycles and gains usable capacity without touching the equipment.
-
Baffles and ventilation
The soffit is the vented panel under the eave. Baffles keep the new depth from blocking the soffit ventilation that keeps the attic breathing.
Brands we work with
Your attic is why the A/C never rests
On a Florida afternoon the attic is the hottest place in the home, and every room underneath pays for it. Heat presses down through the ceiling while the air conditioner fights back.
Why it matters
Benefits of getting attic insulation
Every Attic Insulation job we take is permitted and built to Florida code.
Our process, step by step
-
Free attic inspection
We measure existing depth and coverage, check ventilation paths, and look for moisture damage. 30-45 minutes, no obligation.
-
Itemized quote
Within 3 business days: air-sealing, baffles and dams, material and depth to reach R-38, all listed.
-
Prep and air-sealing
Penetrations sealed, fixtures dammed, eave baffles installed so ventilation stays open at full depth.
-
Installation
We blow insulation to a verified, even R-38 depth across the attic plane. Many homes are done in under a day.
-
Verification
Depth markers confirm coverage, the hatch gets an insulated cover, and we leave you the documentation of the installed R-value.
Licensed, insured, and permitted in every county we serve.
Frequently asked questions
What is R-38 and why that number?
R-value measures how well insulation resists heat flow, and higher is better. R-38 is the level recommended for Florida attics under Department of Energy guidance. It comfortably exceeds the minimum code level for new construction. The upgrade stays ahead of requirements rather than chasing them.
How fast does insulation pay for itself?
It is consistently ranked among the fastest-payback home efficiency upgrades. The A/C is the dominant electric load in South Florida, and the attic is its biggest enemy. Exact savings depend on your current insulation level. Going from nearly nothing to R-38 matters more than topping up.
Can you insulate over my existing insulation?
It depends on the condition of what is there. If the existing layer is dry and uncontaminated, we blow over it to reach R-38 total. Wet, moldy, or rodent-damaged material gets removed first. We will tell you which case yours is at the inspection.
Will more insulation make my attic or roof hotter?
The attic runs about the same, because ventilation governs attic temperature. That is why we baffle the eaves, so airflow stays open. What changes is your ceiling: heat stops pouring through it into the home.
How long does the job take?
We complete a typical home in half a day to a day, including the air-sealing prep. The work happens in the attic, with no disruption to the living space below.
Does attic insulation help in winter too?
Yes. The same resistance works in both directions, holding warmth in on the few cold nights Florida gets. But the real payback here is the ten months of cooling season.
