Impact Windows vs. Hurricane Shutters in Florida

Impact-rated windows and doors replace the existing unit. The protection is built into the product: laminated glass bonded to an interlayer, set in a reinforced frame that is anchored into the wall. It is evaluated and approved as a complete assembly, and once installed there is nothing to put up or take down.

Hurricane shutters leave the existing window or door in place and cover the opening when a storm approaches. The shutter and its track, fasteners and anchorage form the approved system. Protection exists only when the shutter is closed or installed.

In both cases the approval attaches to a specific product in a specific configuration for specific conditions. "Impact" or "hurricane" on a brochure is not by itself evidence that a product is approved for your opening.

This is the single largest practical difference, and for many homeowners it decides the question.

• Impact units protect the opening whether or not anyone is home, which matters for seasonal residents, rental properties and anyone who travels.
• Shutters require someone physically present, with enough notice and physical ability, to deploy them before the weather arrives.
• Accordion and roll-down shutters shorten deployment considerably compared with removable panels, though they still require action.
• Panels must be stored somewhere dry and accessible, kept complete with their hardware, and carried and fitted opening by opening.
• If a storm is forecast while you are away, an unprotected opening behind a shutter that was never deployed is simply an unprotected opening.

• Removable panels — steel or aluminum panels that bolt into tracks or anchors. Usually the least expensive option per opening, and the most labor at deployment.
• Accordion — permanently mounted beside the opening and drawn across on a track. Quick to deploy, visible year-round.
• Roll-down — housed in a box above the opening and lowered manually or by motor. The fastest to deploy, generally the most expensive shutter option, and the one with the most hardware to maintain.
• Bahama and colonial — hinged shutters that stay attached and are closed before a storm. Chosen partly for appearance; Bahama styles also provide shade.
• Fabric screens — flexible engineered panels that attach over an opening. Lighter to handle and store than rigid panels, with their own approval documentation.

Plywood is not on this list deliberately. It is an emergency measure of last resort, not an approved protection system, and it should not be treated as a substitute for either option.

The two options are not the same kind of project, which is why comparing them purely on price rarely reflects what you are actually buying.

• Impact replacement removes and replaces the window or door itself, which means finish work — stucco, drywall, trim, paint — is part of the conversation.
• Impact units are typically special-order after field measurement, so manufacturing lead time is usually the longest part of the schedule.
• Shutter installation works on the surrounding structure rather than the opening, so the existing windows stay as they are, for better or worse.
• Shutter anchorage still has to be attached into sound substrate, and older stucco or block conditions can complicate that.
• Both are generally permitted work, and both should have an opening-by-opening scope rather than a single lump sum.

One point worth being explicit about: shutters protect an existing window. If that window is old, leaking or hard to operate, shutters do not address any of that. Impact replacement solves the protection question and the window-condition question at the same time, which is part of why the projects are priced so differently.

• Impact units are maintained like any other window or door — seals, hardware, operation and cleaning.
• Accordion and roll-down systems have tracks, wheels, locks and, for motorized units, a motor and controls that need periodic exercise and lubrication.
• Coastal salt air is hard on shutter hardware; systems left unused for years are the ones that stick when they are finally needed.
• Panels need an inventory check before each season: all panels present, labeled by opening, with the right bolts and wing nuts.
• It is worth deploying a shutter system once, calmly, before the season, rather than discovering a problem under a watch.

Impact units look like ordinary windows and doors, and daylight and views are unchanged when no storm is present. Some products offer tint or coatings that affect appearance, and glass thickness can be noticeable up close.

Shutters are visible year-round to varying degrees — accordion housings and roll-down boxes sit permanently at the opening, while panels are absent until deployed. Once closed, most shutter systems block daylight and the view entirely, which is a real consideration for a multi-day event with power out. Homeowner and condominium associations sometimes have opinions on visible exterior hardware.

Both options are subject to the same basic framework. The product must be approved for the conditions at your address, installed to the attachment details that approval specifies, and generally permitted and inspected by your local building department.

• Ask for the approval number of each product being installed and verify it through the Florida Product Approval search.
• Miami-Dade and Broward fall in the High-Velocity Hurricane Zone, where a stricter set of requirements applies; most of Florida does not.
• Confirm who pulls the permit and that it is closed after a passed final inspection.
• Mixed projects are common — some openings impact, some shuttered — and the scope should say which is which.

Insurers may consider verified opening protection when rating a policy, typically through a wind mitigation inspection. Both approved impact products and approved shutter systems can be documented on that inspection; what matters is that the protection is an approved system, covers the openings the inspection looks at, and is documented.

Whether any of that changes a premium is determined by your insurer and your policy, not by the contractor and not by us. No discount is guaranteed and no contractor can commit to one on your behalf. For how the inspection itself works, see Florida Wind Mitigation Improvements.

There is no universally better option. In practice the decision usually turns on a small number of factors:

• Who will be at the property when a storm is forecast, and whether deploying shutters is realistic for them.
• The condition and age of the existing windows and doors, and whether they need replacing anyway.
• Budget, and whether the project is being done all at once or in phases.
• How the house is used — full-time residence, seasonal home or rental.
• How much visible exterior hardware you are willing to live with year-round.
• Whether specific openings are unusually large, high or awkward to reach.

Many Florida homes end up with a mix: impact units on the openings that are difficult to reach or already due for replacement, shutters elsewhere. That is a legitimate outcome, not a compromise, provided every protected opening uses an approved system.

We deliberately do not publish cost ranges here. A figure that is accurate for three small openings is misleading for a whole house, and the reverse is equally true. Written proposals on your actual openings are the only reliable number.

• An opening-by-opening list with size, product and approval number — not a single lump sum.
• Which openings are covered and which are being left unprotected.
• Whether permit fees, engineering and inspection coordination are included.
• For impact: whether stucco, drywall, trim, paint and debris removal are included or excluded.
• For shutters: what the anchorage attaches to, and what happens if the substrate is unsound.
• Lead time and installation duration, stated separately.
• Deposit, payment schedule and what each payment corresponds to.
• Product warranty and workmanship warranty, both in writing, with their separate terms.
