Impact Windows vs. Hurricane Shutters: Which Is Better for Florida's Space Coast?

Neither option is better for every home. Impact windows and approved hurricane shutters can both meet Florida's opening protection rules and can both qualify for wind mitigation credits. The real difference is that shutters cost much less upfront but protect only when someone closes them, while impact windows cost more and protect whenever the windows are shut. On the Space Coast, where some owners spend summers away and barrier island homes face open water, that difference often decides it.

Impact windows vs. shutters at a glance

What each option costs

Impact windows are priced per opening. Shutters are priced per square foot of the window or door they cover: a 3 × 5 ft window is 15 sq. ft., and an 8 ft sliding door about 56 sq. ft.

These are our Florida planning ranges. Brevard isn't in the High-Velocity Hurricane Zone, which covers only Miami-Dade and Broward, so that zone's premium doesn't apply. For Brevard factors such as barrier island exposure, see impact window cost in Brevard County.

Same house, priced both ways

This illustrative scenario uses only the ranges above. It's an estimate, not a quote, and each total is rounded the way our calculators round.

Assumptions: a one-story home with eight standard windows of about 3 × 5 ft (8 × 15 = 120 sq. ft.) and one two-panel sliding glass door of about 56 sq. ft., for 176 sq. ft. of openings. It leaves out the entry door, the garage door, permit fees and any repairs found when old windows come out.

Three things stand out. Motorized roll-downs on every opening can cost about as much as impact windows. The cheapest options, panels and fabric, take the most work before each storm. And putting a shutter over the slider instead of buying an impact door cuts the estimate by roughly $1,700 at the low end and $4,000 at the high end, which is why mixing the two can make sense.

The real budget also has to cover the entry door and the garage door, because insurers look at every opening. Our planning range for a single impact entry door is $2,500–$5,000; see impact front door costs. Shutter prices by type are in the hurricane shutter cost guide, and whole-house impact budgets are in the impact window cost guide. To price your own windows:

Protection: impact rating, wind pressure and installation

Both options have to pass two different tests.

• Impact resistance is about wind-borne debris. Florida Building Commission course material says that where the code requires impact protection, glazed openings within 30 ft of the ground must pass the large-missile test (ASTM E1996) and higher openings the small-missile test. Impact glass passes by staying in its frame even when it cracks. A shutter passes by stopping the missile before it reaches the glass.
• Design pressure is the wind load, pushing in and pulling out, that the product is approved to resist. Approvals list design pressures by configuration and size, so a product approved at one size isn't automatically approved at a larger one.

Every window, door and shutter needs a Florida product approval or a Miami-Dade Notice of Acceptance, and the approval sets how it must be fastened, so a good product with the wrong anchors isn't the product that was tested. You can look up approval numbers on the Florida Building Commission's product approval search; our guide to hurricane codes and product approval explains the terms.

In the wind-borne debris region, glazed openings must be impact-resistant or covered by approved impact protection, and either option can meet that. No product guarantees a home will come through a hurricane undamaged.

Convenience: who closes the shutters?

For most families this matters more than any spec sheet.

• Storm panels are stored between storms and put up before each one. They cost least, but they're heavy, have sharp edges and need storage space, and putting them up on a two-story house is a real job.
• Fabric screens are lighter and easier to store, but still have to be anchored over each opening. Our impact windows vs. hurricane screens guide compares them in detail.
• Accordion shutters stay mounted beside the opening and fold across it. A FEMA fact sheet on shutter alternatives lists them as preinstalled and easy to use, but somewhat expensive and less attractive.
• Roll-down shutters sit in a box above the opening and lower by crank, strap or motor. FEMA lists them as preinstalled, easy to use and able to be motorized, but very expensive. Motorized units need a manual backup for power outages.
• Impact windows need nothing beyond being shut.

Metal shutters leave rooms dark while they're closed. Clear polycarbonate panels let light in but cost more.

Insurance credits: the doors make the difference

Section 627.0629, Florida Statutes, requires insurers' rate filings to include discounts, credits, other rate differences or lower deductibles for features shown to reduce wind losses, including opening protection. An inspector records it on the state's wind mitigation form (OIR-B1-1802). A revised version took effect April 1, 2026, and opening protection is among the features updated on it, but the summaries we found don't spell out the new categories.

My Safe Florida Home's explanation, which may describe the earlier form, sets out three top levels: A.1 when every opening, glazed or not, is rated for large-missile impact; A.2 when all the glass is rated and the solid entry and garage doors are verified as rated for wind pressure; and A.3 when the glass is rated but those doors can't be verified. The levels describe tested performance, not whether the glass itself is impact-rated or covered by a shutter, so both approaches can qualify. Where they differ is the doors:

• With impact windows, the front door, side doors and garage door are separate purchases. New windows alone leave the solid doors to be documented or replaced.
• With shutters, a rated shutter may cover a door opening if its approval allows that, which can cost less than a new impact door. Ask a wind mitigation inspector how it would be rated.

We haven't found an official statement that the two approaches always earn the same credit, and amounts vary by insurer, so ask your agent before you buy. See do hurricane shutters lower insurance costs? for the paperwork and the wind mitigation inspection guide for the inspection.

Appearance, upkeep and salt air

Impact windows look like ordinary windows. Shutters change the outside of the house: accordion tracks and roll-down boxes stay visible all year, and storm panels leave tracks or anchors behind. HOA specifications can regulate those details (see below).

Either way, metal sits in salt air all year: window frames and hardware, or shutter tracks, anchors, slats and motors. Some window warranties exclude salt damage or shorten coverage near salt water, and coastal warranties often require regular cleaning (one requires washing exterior surfaces at least every two months), so skipped maintenance can void coverage. FEMA says Type 316 stainless steel resists coastal corrosion better than Type 304. Ask any installer to put the finish specification, the stainless grade of exposed hardware and the warranty's coastal terms in writing; our guide to corrosion-resistant windows and doors goes further.

Space Coast homes

Barrier island and waterfront lots

The barrier island communities, from Cocoa Beach and Satellite Beach to Indian Harbour Beach, Indialantic and Melbourne Beach, sit between the Atlantic and the lagoon waters of the Banana River and Indian River. Whichever option you choose, two things matter more there:

• Design pressure. Brevard County's building code wind speed maps give an address's design wind speed (homes are generally Risk Category II). That speed and the lot's exposure help set the design pressures your windows or shutters must meet, and lots facing open water can fall in a more severe exposure category. We haven't confirmed how Brevard's building officials draw the wind-borne debris region or apply exposure along the ocean and lagoon, so ask your building department or installer about your address.
• Fasteners. The Florida Building Commission's summary of the 2026 Florida Building Code (9th Edition, which takes effect December 31, 2026) describes new corrosion-resistance requirements for certain fasteners and metal connectors within 3,000 ft of a saltwater coastline. We haven't confirmed how they apply to window and shutter anchors, so ask your installer and building department.

Seasonal residents and second homes

Hurricane season runs from June 1 to November 30, when seasonal owners are often away. A shutter protects only when it's closed, so:

• Impact windows and doors protect without anyone on site. For owners who are away in summer, that's the strongest argument for them.
• If you choose shutters, decide now who will close them and put it in writing. That person needs access to the house, the crank, keys or remote, labeled panels with their hardware, and a plan for when the same storm threatens their own home.
• Motorized roll-downs still have to be lowered before a storm, and need a manual override for power outages.
• If you'd leave shutters closed all season, ask your HOA or condo association whether its rules allow it.

Condo unit owners fall under a different chapter of Florida law and their association's own hurricane protection rules, so ask the association what's allowed and who installs it. For the cost-benefit on beachside homes, see are impact windows worth it on the Space Coast?

HOA hurricane protection specifications

Section 720.3035(6), Florida Statutes, added in 2024, requires a homeowners' association's board or architectural committee to adopt hurricane protection specifications for each structure or other improvement on a parcel. The specifications can set colors and styles and must comply with the building code. The association may not deny an application to install, enhance or replace hurricane protection that conforms to them, though it can still require you to follow an existing unified look for the community. Summaries of the 2024 law list shutters, impact-resistant windows and doors, and reinforced garage doors among the types of hurricane protection.

Get the current specifications before you collect quotes, give them to installers so their quotes match, and get written approval before you sign or pay a deposit. Since July 1, 2026, an HOA can't require a building permit before it reviews your application, so you can apply for both at once. See HOA approval in Florida.

Permits in Brevard County and its cities

Who issues your permit depends on where the home is, not your mailing address.

• Unincorporated Brevard, including communities such as Viera, Suntree and Merritt Island: the county's residential doors, windows and shutters permit covers exterior doors, windows, garage doors and hurricane shutters on one- and two-family homes. It asks for a product approval summary or Florida product approval, the manufacturer's installation instructions and a floor plan showing where each product goes. Licensed contractors file online through the county's BASS system; owner-builders apply in person.
• Cities and towns issue their own permits. Melbourne and Indian Harbour Beach list window and door replacement among work that needs one (see window replacement permits in Melbourne), and West Melbourne asks for a product approval affidavit and a drawing of the numbered openings on window and door permits. In Palm Bay, Satellite Beach, Melbourne Beach, Cocoa Beach and elsewhere, ask what your city needs for windows and for shutters.

Don't assume window or shutter work qualifies for Florida's under-$7,500 permit exemption. It excludes structural work and any property in a designated flood hazard area, wiring a motorized shutter is electrical work that needs a permit at any value, and the exemption has to be requested in writing. We found no Brevard County page on how the county handles requests, so ask the county building department. See the $7,500 permit exemption, building permits in Brevard County and window and door permits in Florida.

Which option suits whom

Impact windows and doors tend to suit you if:

• you're away for part of hurricane season, or the house is a second home or rental
• you can't safely lift panels or climb ladders, or the home has many second-story windows
• your windows are old and due for replacement anyway
• you want noise reduction and security from the same purchase

Storm panels or fabric screens tend to suit you if:

• you're home all season and able to put them up, with help if needed
• your windows are in good condition and you don't want to replace them
• budget comes first, and you have dry storage space for panels

Accordion or roll-down shutters tend to suit you if:

• you want shutters without the storm-day labor of panels
• you have large openings such as wide sliders, where a roll-down is practical
• you accept the higher cost and the visible tracks or boxes

A combination tends to suit you if:

• one or two openings, such as a big lanai slider, would cost much more in impact glass than under a shutter
• you're replacing some windows now and others later

Whatever mix you choose, what matters for code and insurance is that every opening, including the entry door and garage door, ends up rated or covered by approved products, with paperwork to prove it.

Common mistakes

• Leaving one opening unprotected. An unrated garage door or entry door can keep you out of the best opening protection rating, and it leaves a gap in the home's protection.
• Comparing quotes that cover different openings. Every quote should list the same openings, sizes, product approval numbers and design pressures. See why contractor quotes differ.
• Buying "hurricane rated" without checking the approval. A product has to be approved for your opening's size and design pressure.
• Storing panels without a system. Label each panel by opening and keep its hardware with it, or the first storm becomes a puzzle.
• Motorized shutters with no manual override. If the power goes out, you still need a way to close and open them.
• Ordering before HOA approval. Get the association's specifications and written approval first.
• Waiting for a storm in the forecast. Custom-sized impact units often take several weeks or more to order, the permit adds time, and lead times stretch around hurricane season.

Next steps

1. Find out who issues your permit: Brevard County, or your city or town.
2. Look up your address on the county's wind speed map, and ask installers what design pressures your openings need.
3. If you have an HOA, get its hurricane protection specifications.
4. Ask your insurance agent how your insurer credits opening protection, and whether it needs an A.1 or A.2 rating.
5. Get itemized quotes that list every opening with the product, approval number, design pressure, finish and warranty terms. Check each contractor's license first with our contractor checklist.
6. After the final inspection, schedule a wind mitigation inspection and send the report to your insurer.
