Every June, the same conversation plays out in thousands of Broward and Miami-Dade households. Hurricane season is here, the forecasters are talking about an active year, and the question gets asked again: do we finally invest in impact windows, or do we stick with the storm panels stacked in the garage? The impact windows vs storm panels debate is one of the most consequential home-improvement decisions a South Florida homeowner will make, and the right answer depends on more than just sticker price.
After two decades of installing both systems across Fort Lauderdale, Hollywood, Pembroke Pines, Miami, Coral Gables, and Doral, we have seen what each option actually delivers when a Category 3 is bearing down on the coast and what they cost in terms of money, time, storage space, and quality of life the other 360 days of the year.
This guide walks through the four most common storm-panel materials, compares them honestly against impact-rated glass, and gives you the framework to decide which solution fits your home, your budget, and your tolerance for pre-storm labor.
What Storm Panels Actually Are
Storm panels are removable barriers installed over your existing windows and doors before a hurricane arrives. They bolt, slide, or clip into permanent tracks or anchors mounted around each opening. After the storm passes, you take them down and store them until the next threat.
South Florida homeowners typically choose between four panel materials, and the differences matter.
Steel Storm Panels
Galvanized or painted steel panels are the heavy-duty option. They are corrugated, overlap at the seams, and bolt into permanent headers and sills with wingnuts. Steel panels offer excellent impact resistance and are often the cheapest per square foot. The trade-off is weight. A single panel covering a 6-foot sliding glass door can run 40 to 60 pounds, and lifting one over your head onto a second-story window is a real workout. Steel also rusts in our salt-laden coastal air if the coating gets scratched.
Aluminum Storm Panels
Aluminum panels look similar to steel but weigh roughly half as much. They resist corrosion better, which matters for any home east of US-1. They cost more than steel per panel and dent more easily, but most homeowners find them dramatically easier to install when a storm is 48 hours out. Aluminum is the most common storm-panel material we see in Broward and Miami-Dade today.
Lexan (Polycarbonate) Panels
Lexan panels are clear or smoke-tinted polycarbonate, roughly 250 times stronger than glass at the same thickness. The huge advantage is light. You can keep them installed for days without living in a pitch-black bunker, which matters when power is out and you are running a generator. The downsides are cost (typically the most expensive panel option), scratching during storage, and yellowing over time from UV exposure.
Accordion and Roll-Down Shutters
Worth mentioning even though they are not technically removable panels: accordion shutters fold horizontally from the side, and roll-downs deploy from a housing above the window. They stay permanently attached, eliminating storage, but they add visible hardware to the exterior and require manual or motorized operation before every storm.
What Impact Windows Bring to the Equation
Impact windows look like ordinary windows. The difference is in the glass: two panes of tempered or heat-strengthened glass laminated to a tough PVB or SGP interlayer, set in heavy-duty aluminum frames engineered to flex without failing under hurricane wind pressures.
When a 2×4 hits an impact window at 50 feet per second (the Miami-Dade Large Missile Impact test), the outer glass cracks but the interlayer holds everything together. The opening stays sealed. Wind, rain, and pressure stay outside.
At A Plus Impact Windows & Doors, the primary product line we install is ES Windows, manufactured locally in Medley, Florida. Their Series 100 single-hungs, Series 200 horizontal rollers, Series 300 casements, Series 400 fixed picture windows, and Series 500 awnings all carry current Miami-Dade Notices of Acceptance (NOAs) and are approved for installation throughout the High Velocity Hurricane Zone (HVHZ) that covers Broward and Miami-Dade Counties. Because ES Windows is built locally, lead times are shorter than national brands and the frames are engineered specifically for our coastal climate.
Cost: The Real Numbers
This is usually where the conversation starts, so let us put real ranges on the table. Pricing varies by opening size, glass thickness, and frame configuration, but these figures are representative for South Florida in the current market.
| Protection Method | Installed Cost per Window Opening | Typical Lifespan |
|---|---|---|
| Steel storm panels | $8 to $15 per square foot | 15 to 20 years |
| Aluminum storm panels | $12 to $20 per square foot | 20 to 25 years |
| Lexan panels | $18 to $30 per square foot | 10 to 15 years |
| Accordion shutters | $25 to $45 per square foot | 20+ years |
| Impact windows (ES Windows) | $60 to $120 per square foot | 30+ years |
On paper, panels win the upfront cost comparison decisively. A typical 2,000-square-foot Broward home with 15 openings might run $4,000 to $8,000 in aluminum panels versus $20,000 to $35,000 in impact windows. That gap is real, but it does not tell the whole story once you factor in insurance, energy, resale, and the value of your time.
Installation Effort and Storage
This is the category most homeowners underestimate until their third hurricane season.
The Pre-Storm Reality with Panels
When a storm enters the cone, you have roughly 48 to 72 hours of advance notice. During that window, you need to pull every panel out of storage, carry it to the correct opening (panels are usually labeled, but they get mixed up), align it with the tracks or studs, and secure every wingnut or bolt. A typical Broward home with 15 to 20 openings takes a fit homeowner six to ten hours of ladder work, often in 90-degree heat with rain bands already moving in. Many older homeowners simply cannot do this work themselves anymore and have to pay a service $400 to $800 per deployment.
Storage Demands
Panels for a full house can fill an entire single-car garage bay or a 5×10 storage shed. They need to stay dry, organized, and accessible. In condos and townhomes with limited storage, this alone is often the dealbreaker.
Impact Windows
Pre-storm preparation is exactly zero. You bring the patio furniture in and check the generator. That is it. For homeowners with mobility issues, demanding jobs, frequent travel, or rental properties, this difference is enormous.
Insurance Credit Eligibility
Florida homeowners insurance discounts for hurricane protection are governed by the OIR-B1-1802 wind mitigation form. Both storm panels and impact windows can qualify your home for credits, but the credits are not equal in every situation.
To earn the maximum opening-protection credit, every glazed opening (windows, sliding doors, entry door glass, garage door windows, skylights) must be protected to current Miami-Dade Large Missile Impact standards. Miss one skylight or one bathroom window and the credit shrinks dramatically or disappears.
With storm panels, the credit only counts if the panels are actually deployable. Lost panels, stripped wingnuts, or missing hardware noted during your wind mitigation inspection will reduce the credit. With impact windows, the protection is permanent and verified by NOA documentation, so the credit applies consistently year after year.
In our experience, Broward and Miami-Dade homeowners typically see annual premium reductions of 15 to 45 percent after a full impact-window installation, depending on the carrier, the home, and other wind-mitigation features like roof-to-wall connections.
Everyday Quality of Life
This is the category panels cannot compete in, and it is the reason most homeowners who switch to impact glass say they wish they had done it ten years sooner.
Noise Reduction
The same laminated glass that stops a flying 2×4 also dampens sound. Homes near I-95, the Turnpike, Fort Lauderdale-Hollywood International, Miami International, or busy arterials see noticeable interior noise reduction, often 30 to 50 percent quieter depending on the original windows being replaced.
UV and Energy Performance
The PVB interlayer in impact glass blocks roughly 99 percent of UV radiation, which protects flooring, furniture, and artwork from fading. Add a Low-E coating with a low SHGC (Solar Heat Gain Coefficient) and your AC works measurably less during August. ES Windows offers Low-E options on every series, and many configurations qualify for ENERGY STAR in the Southern climate zone.
Security
Laminated impact glass is extremely difficult to break through. Burglars who smash a typical window are inside in under ten seconds. The same attack on impact glass leaves a cracked, intact barrier that holds long enough for alarms to summon a response.
Light and Views
You never lose your view to a panel. The house never goes dark during a storm watch. You do not spend the day before landfall in your garage hunting for the panel labeled MBR-NORTH.
Which Option Is the Best Way to Protect Windows From a Hurricane?
If budget is the absolute constraint and storage is not an issue, aluminum storm panels remain a defensible choice. They meet code, they earn an insurance credit when deployed correctly, and they protect your openings.
For almost every other scenario, impact windows win the long-term math. Lower insurance premiums year after year, lower energy bills, higher resale value, no pre-storm labor, no storage burden, and dramatically better daily livability add up to a system that pays for a meaningful portion of itself over its lifespan. For waterfront properties, second homes, rentals, and any household where the homeowners are not eager to spend a Saturday on a ladder before every named storm, the decision is usually clear.
Frequently Asked Questions
Are storm panels still legal under the current Florida Building Code?
Yes. Storm panels that carry a current Miami-Dade NOA or Florida Product Approval for Large Missile Impact remain code-compliant in the HVHZ and throughout Florida. The product must be installed per the approval documents, with the correct anchors and spacing.
Can I mix impact windows and storm panels on the same house?
You can, and many homeowners phase their projects this way to spread cost. Keep in mind that the maximum insurance credit requires every opening to be protected to the same impact standard, so partial conversions earn smaller premium reductions until the project is complete.
Do impact windows break during a hurricane?
The outer pane can crack on direct impact, which is the system working as designed. The laminated interlayer holds the glass in place and keeps the opening sealed. The window does not need to be replaced unless the glass is visibly damaged after the storm.
How long does an impact window installation take in Broward or Miami-Dade?
From signed contract to final inspection, a typical full-home project runs eight to fourteen weeks. Manufacturing is the longest phase, which is one reason we install ES Windows from Medley rather than waiting on out-of-state production. Permitting in Broward and Miami-Dade typically adds two to four weeks.
Will impact windows qualify me for a wind mitigation insurance discount?
Yes, provided every glazed opening on the home is rated for Large Missile Impact and verified on your OIR-B1-1802 wind mitigation form by a licensed inspector. The credit varies by carrier but is typically substantial.
What happens to my old storm panels if I switch to impact windows?
Most homeowners sell them on Facebook Marketplace or to neighbors. Some donate them. The tracks and headers can usually stay in place during impact-window installation or be removed and the holes patched and painted.
Are Lexan panels worth the extra cost?
For homeowners who want some interior light during extended power outages and who can store them carefully to avoid scratching, yes. For most South Florida homes, the cost premium over aluminum is hard to justify when impact glass delivers permanent light plus every other benefit.
