Florida Insulation FAQs

Most Boca Raton and Delray Beach attics land between $1.10 and $1.90 per square foot for blown fiberglass to R-38, which is roughly $2,200 to $4,500 for a typical 2,000 square foot home including air sealing and baffles. Removing old insulation adds about $1.00 to $2.00 per square foot, and spray foam on the roof deck runs $2.20 to $6.50 per square foot. See our Delray Beach attic insulation guide and Boca Raton spray foam cost guide.

Both cities are in Palm Beach County, which falls in Florida Climate Zone 1 under the Florida Building Code, Energy Conservation (8th Edition). The code minimum for attics is R-30. We recommend R-38, because settling and thin spots at the eaves mean an R-30 attic often performs closer to R-24 after a few years.

Yes. Palm Beach County is where we run our densest schedule, and we work throughout both cities — single-family homes, villas, condos and 55+ communities such as Kings Point in Delray Beach, plus commercial buildings along the Federal Highway and Atlantic Avenue corridors. See our Boca Raton and Delray Beach pages.

Both cities are served by FPL. FPL's ceiling insulation program pays $220 per installation when existing ceiling insulation is below R-8 and the home has whole-house central electric air conditioning and heating. The work must be done by an FPL Participating Independent Contractor, and the credit appears on the contractor's invoice. Details: the FPL insulation rebate in 2026.

No. The federal Energy Efficient Home Improvement Credit (Section 25C) ended for improvements placed in service after December 31, 2025, so insulation installed in Boca Raton or Delray Beach in 2026 doesn't qualify. The FPL ceiling insulation rebate is still available for homes that meet its requirements.

For most vented attics, blown fiberglass to R-38 with air sealing is the best value. Spray foam on the underside of the roof deck makes more sense when the ducts and air handler sit in the attic, or when the roof is flat or low-slope with little attic space — common in older Delray Beach homes and additions. Compare them in blown-in vs. batt insulation and spray foam in Delray Beach.

Yes. We vacuum-extract wet, moldy or rodent-contaminated insulation through a hose to the outside, so it never comes through the house, then air seal and reinsulate. Removal typically runs $1.00 to $2.00 per square foot. See attic insulation removal in Delray Beach.

Yes. Condos, villas and townhomes often have shallow attics shared across units, so air sealing between units matters as much as insulation depth. Your association may have rules about access, scheduling or contractor insurance, so we coordinate with the HOA or property manager when needed.

Yes — offices, retail, restaurants, medical buildings, warehouses and mixed-use properties. We install spray foam, batt, metal building and fire-rated assemblies and work from plans at bid stage. See commercial fireproofing in Boca Raton and fireproofing for Delray Beach restaurants.

Usually, yes — especially when ducts are in the attic. Most of the heat entering a South Florida attic radiates down from the hot roof deck, which a radiant barrier reflects. It costs about $0.60 to $1.40 per square foot and works alongside R-38 attic insulation, not instead of it. See radiant barrier in Delray Beach.

Most Florida attic insulation projects fall between $1.50 and $4.50 per square foot installed. Blown-in fiberglass to R-38 sits at the low end; closed-cell spray foam on the roof deck sits at the high end. A typical 2,000 sq ft South Florida home runs roughly $2,200–$4,500 for a blown-in attic top-up and $6,000–$13,000 for a full spray foam roof deck encapsulation. Insulation removal adds roughly $1.00–$2.00 per square foot. Every estimate we give is free, written, and itemized.

The Florida Building Code, Energy Conservation (8th Edition) places most of the state in Climate Zone 2, with seven southern counties — Broward, Collier, Hendry, Lee, Miami-Dade, Monroe and Palm Beach — in Zone 1. Attics require R-38 minimum in Zone 2 and R-30 in Zone 1, with R-38 to R-49 the practical target for comfort and utility savings. Homes built before roughly 2005 frequently still have R-11 to R-19, which is a large part of why their summer bills are what they are.

Fiberglass and mineral wool essentially last the life of the building if they stay dry and undisturbed. Cellulose settles 10–20% over a couple of decades and loses some R-value with it. Spray foam does not settle or degrade. The realistic enemies in Florida are water intrusion, rodents, and crews walking on it during other trades' work — not age.

Not if the existing material is dry, uncontaminated, and reasonably even — adding on top is standard practice and saves you money. You do need removal if it's wet, matted, rodent-soiled, moldy, smoke-damaged, or full of construction debris. We'll show you photos of what's actually up there and tell you honestly which situation you're in.

A typical residential attic top-up is a half day to a full day. Removal plus reinstall is usually one to two days. A full spray foam roof deck encapsulation on an average home is one to two days plus cure and ventilation time. Commercial and industrial scopes are scheduled against your construction timeline.

For blown-in and batt, no — though you may want to stay out of the immediate work area. For spray foam, yes: the space needs to be vacated during application and for the manufacturer's specified re-occupancy period, typically 24 hours. We'll tell you exactly what to expect before the day of.

Yes. Standard Insulation is a licensed Florida insulation contractor carrying general liability and workers' compensation coverage. We provide certificates of insurance to homeowners, general contractors, and property managers on request before mobilization.

We can discuss payment structuring on larger projects. Ask about it during your estimate and we'll go over what's available for your scope.

Yes. Open 24/7 is literal. Storm damage, roof leaks, and emergency removal don't wait for business hours, and a meaningful share of our commercial work happens overnight in occupied buildings.

Every incorporated city and major community in all 67 Florida counties. Our densest crew coverage is Palm Beach County, Broward, and Miami-Dade. For larger commercial and industrial scopes we mobilize statewide, Panhandle to the Keys.

Different jobs. Blown-in fiberglass is the best dollar-for-dollar way to raise attic R-value quickly. Spray foam is better when you want to move the thermal boundary to the roof deck, bring ducts and the air handler into conditioned space, air-seal, and control humidity. In a hot-humid climate, closed-cell foam on the roof deck usually delivers the biggest total comfort win — but it costs several times as much upfront. If your budget is tight and your attic is at R-13, blown-in gets you most of the improvement.

Open-cell is about R-3.7 per inch, soft, vapor-permeable, and less expensive. Closed-cell is about R-7.0 per inch, rigid, vapor-retarding at roughly two inches, and adds structural racking strength — which matters in Florida's High-Velocity Hurricane Zone. General rule here: closed-cell on the roof deck, open-cell where you have deep cavities and want sound damping at lower cost.

We usually lean fiberglass for Florida attics. It doesn't absorb water, doesn't settle much, and doesn't feed mold — real advantages in a climate where your attic will eventually see water. Cellulose has slightly better R-per-inch, fills irregular cavities better, and is superior acoustically, so it's often the right pick for dense-pack wall retrofits and sound work.

Fi-Foil is a Florida manufacturer of reflective insulation and vapor-control systems engineered for hot-humid climates. Because roughly three-quarters of the heat entering a Florida attic arrives as radiant energy rather than conduction, reflective foil systems reject a large share of the load with a thin, inexpensive material. Their furring-strip systems are also one of the few practical ways to insulate an existing CMU block wall from the interior.

Yes, when installed correctly — meaning it faces an open air space, typically stapled to the underside of the rafters or as foil-faced roof sheathing. Field measurements in Florida attics consistently show 20–30°F reductions in peak attic temperature. Expect roughly 8–12% cooling savings from a radiant barrier alone. It is a multiplier on top of adequate R-value, not a replacement for it. Foil laid flat on top of attic insulation does not work well and can trap moisture.

Mineral wool costs more than fiberglass but is denser, non-combustible, water-repellent, and substantially better acoustically. It's the right choice for fire-rated assemblies, mechanical rooms, demising walls, and any bedroom facing a busy road.

Unfaced, in most Florida wall assemblies. Kraft facing is a vapor retarder designed for cold climates where assemblies dry outward. In our climate, vapor drive runs inward and an interior kraft facing can trap moisture inside the wall.

Properly installed and fully cured spray foam is inert and safe. The risks are all in the installation: off-ratio material, wrong substrate temperature, or too-thick passes produce foam that doesn't cure correctly and can retain odor. This is why installer quality matters more with foam than with any other insulation product. We monitor and log substrate temperature and apply in controlled lifts.

Three reasons. First, our dominant heat load is radiant off the roof, not conductive — which is why radiant barriers matter so much here and so little in Minnesota. Second, our vapor drive runs inward, so vapor retarders belong in a different plane than they do in cold climates, and getting it backwards traps moisture in your walls. Third, our air conditioning has to dehumidify as well as cool, so air leakage in the ceiling plane costs you twice.

130–150°F on a clear August afternoon is typical, and roof sheathing surfaces can exceed 160°F. If your air handler and ductwork live up there — and in a large share of Florida homes they do — that's the environment your cooling system is operating in.

Insulation alone, marginally. Air sealing combined with insulation, significantly. Most of the humidity entering a Florida house comes in with leaked air, not through materials. Sealing the ceiling plane and, in a spray foam attic, eliminating the vented attic entirely, is what actually moves indoor relative humidity.

Closed-cell spray foam adhered to the roof deck measurably increases the uplift resistance of roof sheathing, which is a real structural benefit in a wind event. Beyond that, a well-insulated, air-sealed home holds temperature far longer during a power outage — which can be the difference between uncomfortable and dangerous when the grid is down for days.

Realistically, no. Wet insulation in a Florida attic does not dry — it stays wet, loses R-value permanently, grows mold, and holds odor. Full removal, sanitizing, drying the structure, and reinstalling is the correct response. If your roof took damage, have the attic checked even if the ceiling looks fine; staining and smell often show up weeks later.

The High-Velocity Hurricane Zone covers Miami-Dade and Broward counties, with stricter wind-borne debris and product approval requirements. It primarily affects roofing, windows, and doors, but it does influence roof deck attachment details and product approvals for materials applied to the deck. We install to HVHZ requirements in those counties.

It depends on the jurisdiction and the scope. Simple attic top-ups often don't require a permit; spray foam roof deck applications, work involving the thermal envelope on a permitted renovation, and all commercial work generally do. We handle permitting where it's required and meet the inspector.

Cooling is roughly half of a typical Florida home's electric bill. Bringing an under-insulated attic from R-11 to a properly air-sealed R-38 commonly cuts the cooling portion by 20–30%. On a $300 summer bill, that's usually $30–$45 a month — more if your ducts are in the attic and you add a radiant barrier.

Yes — free, on site, and with no obligation. We spend about 45 minutes in and around your attic measuring depth, checking for moisture and rodent activity, inspecting duct condition, and photographing what we find. You get the photos and a written scope whether or not you hire us.

In Palm Beach, Broward, and Miami-Dade we can usually be on site for an estimate within 24–48 hours. Emergency removal after a roof leak or storm gets same-day priority whenever we can make it happen. We answer the phone 24/7.

Drop cloths on floors, containment at the attic access, protection along the stair and hallway path, and everything hauled away when we're done. Insulation work is dirty; your house shouldn't be when we leave.

This is the right question to ask, and most homeowners never do. We install depth markers throughout the attic per the manufacturer's coverage chart, photograph them, and leave you the bag count and coverage documentation. You should be able to go up there a year later with a ruler and verify it.

Yes — we warranty our workmanship, and manufacturer warranties apply to the materials. Specific terms depend on the product and scope and are stated in your written proposal.

Regularly. We handle new construction packages for production builders and custom homes, work off your approved energy calculations, provide submittals and certificates of insurance, and commit to schedule dates. If something upstream isn't ready, you'll hear it from us the day we know rather than the morning of.

Yes, and we do it often. Occupied hotels, restaurants, medical suites, and retail frequently require after-hours work with containment and HEPA filtration. It's a normal part of our schedule, not an exception.

Yes — offices, retail, hospitality, medical, education, warehouses, distribution centers, manufacturing, cold storage, hangars, and agricultural buildings. We carry envelope, mechanical, and fire-rated scopes so you're not coordinating three subs across the same interfaces.
