The Short Answer
Impact windows and doors are the most reliable form of hurricane protection for South Florida homes because they meet Miami-Dade County’s strict high-velocity hurricane zone standards without the hassle of putting up and taking down panels every storm season. Unlike plywood or accordion shutters, they work around the clock — no prep time required when a storm is 48 hours out.
For homeowners in Boca Raton, the combination of laminated glass and a reinforced frame keeps wind-driven debris from breaching the building envelope, which is the main cause of catastrophic interior damage during a hurricane.
Why Shutters Alone Often Fall Short
Plenty of local residents have accordion or roll-down shutters and feel covered. Shutters do a solid job blocking direct impact, but they leave a few real gaps worth knowing about.
The Deployment Problem
Accordion shutters require someone to physically close them before a storm. If you’re traveling, evacuating late, or dealing with a fast-moving storm that gives little warning, that step can get skipped. Fabric storm panels are even more time-consuming — they need to be stored, retrieved, and bolted into place, which can take hours for a full house. Impact-rated windows eliminate that variable entirely.
Energy Efficiency and Insurance Savings
Shutters don’t do anything for your home the other 11 months of the year. Impact glass, on the other hand, blocks a significant portion of UV radiation and reduces heat transfer, which translates into lower cooling bills. Many insurance carriers in Florida also offer premium discounts specifically for homes with impact-rated windows installed across all openings. The My Florida Safe Home program has historically offered grants to help homeowners cover the cost of approved upgrades like these — worth checking if you haven’t already.
What the Building Code Actually Requires
Florida’s building code, shaped heavily by the damage patterns from Hurricane Andrew in 1992, requires that all exterior openings in high-velocity hurricane zones be protected. That includes windows, doors, skylights, and garage doors. Shutters satisfy the code, but they must be deployed to count. Impact products are considered “always on” protection and satisfy code requirements passively. You can review product options that meet these standards on the STS products page to see what’s available for both windows and doors.
Choosing the Right Protection for Your Home
The best choice depends on your home’s age, your budget, and how long you plan to stay. Here’s how to think through it.
Older Homes vs. Newer Construction
Homes built before 2002 in the area were often permitted under older, less stringent codes. Those homes frequently have single-pane windows in aluminum frames that provide almost no resistance to hurricane-force wind pressure. Replacing them with modern impact units is a bigger jump in protection than it would be for a home built in 2010. If your home falls into the pre-2002 category, a full window and door replacement is usually the more cost-effective long-term move compared to layering shutters onto frames that weren’t designed for today’s loads.
Budget and Financing Options
Full impact window replacement is a larger upfront investment than buying shutters. That said, financing programs exist specifically for this kind of home improvement. PACE financing options like those covered on the Ygrene Financing page let homeowners pay through their property tax bill over time, which removes the need for a large lump-sum payment. There are also manufacturer-specific promotions and available discounts worth asking about before committing.
Garage Doors: The Often-Forgotten Opening
A standard garage door is one of the largest and weakest openings on most homes. During a hurricane, a failed garage door can cause the roof to lift due to sudden interior pressure changes. Impact-rated garage doors are engineered to handle those wind loads and are a critical part of a complete protection plan — not an optional add-on.

How long does it take to install impact windows on a typical South Florida home?
Most single-family homes in the area can have all windows and doors replaced within two to five days, depending on the number of openings and whether any structural modifications are needed. Permitting timelines vary by municipality and can add a few weeks to the overall project schedule, so it’s worth starting the process before hurricane season rather than during it.
Does impact glass actually stop a category 4 or 5 storm?
Impact glass is tested to resist wind-driven debris traveling at high speeds — the standard test uses a 9-pound 2×4 fired at the glass at 50 feet per second. That doesn’t mean the glass is indestructible in every scenario, but it’s designed to stay in the frame even if it cracks, preventing catastrophic wind and water intrusion. The Florida Building Commission maintains the testing and approval standards all certified products must meet.
