What Category Hurricane Can Hurricane Windows Withstand?
When you live in Florida, hurricane preparedness isn't optional—it’s essential. At Morgan Exteriors, we’re often asked: “What category hurricane can hurricane windows withstand?” It’s a smart question, especially when you’re investing in long-term protection for your home. Let’s break down the science behind hurricane-rated windows, how they’re tested, and how to know if your current windows are truly storm-ready.
The Basics: What Makes a Window “Hurricane Rated”?
What are hurricane windows? A hurricane-rated window isn’t just thicker or stronger than a standard one—it’s engineered with impact-resistant glass, heavy-duty frames, and secure installation techniques that allow it to withstand brutal wind pressure and flying debris.
These windows are tested using a standardized tool to test windows' resistance for hurricane damage, simulating both the wind pressures of a hurricane and the impact of wind-borne objects like branches, shingles, or debris.
The tests mimic real-world storm conditions and include:
- Large missile impact test: A 9-pound 2×4 is shot at the glass at 34 mph to simulate flying debris.
- Cyclic pressure test: Simulated wind gusts push and pull the window thousands of times to replicate storm pressure.
Only windows that pass both are certified as hurricane impact windows.
Are Hurricane Windows Required in Florida?
One of the most common questions Florida homeowners ask is: “Are hurricane windows required in Florida?” The answer depends on your location, the age of your home, and current building codes. In many coastal regions of Florida, the law requires homes to have either impact-resistant hurricane windows or another approved form of storm protection, such as shutters. These codes are designed to protect your family and property from high winds and flying debris during hurricane season.
If you’re unsure whether your home falls under these requirements, it’s important to understand the specific regulations in your area. Florida’s building codes have been updated over the years to strengthen storm safety standards, meaning newer homes are more likely to already include hurricane-rated windows, while older homes may need upgrades.

So, What Category Hurricane Can Hurricane Windows Withstand?
Most hurricane impact windows are designed and tested to withstand Category 5 hurricanes, the highest classification on the Saffir-Simpson scale. That means they can resist wind speeds over 157 mph and the violent debris that often comes with it.
Of course, performance can vary depending on the manufacturer, the type of glass, frame materials, and how well the windows are installed. At Morgan Exteriors, we install premium impact windows in Tampa, Port St Lucie, Fort Myers, and across the great state of Florida. We use hurricane rated window replacements from trusted brands like PGT and Simonton, which are engineered for maximum performance in Florida’s harshest weather conditions.
Hurricane Windows vs. Hurricane Window Shutters
Hurricane shutters are another option for storm protection, and some homeowners use both for added security. However, hurricane window shutters:
- Require manual installation before each storm
- Block natural light
- Often aren’t as effective in prolonged wind exposure
Hurricane windows provide continuous protection with no extra effort before a storm hits. Plus, they also offer everyday benefits like better energy efficiency, UV protection, and noise reduction.
If you're weighing the pros and cons of hurricane window shutters versus impact windows, consider the convenience, appearance, and added year-round benefits of windows built to handle hurricanes 24/7.
Are Double Pane Windows Hurricane Proof?
No, not all double-pane windows are hurricane proof. While double-pane (or insulated glass) windows are excellent for improving energy efficiency and reducing sound, they typically lack the laminated interlayer that makes impact windows shatter-resistant.
Some people confuse double-pane windows with impact windows because both can feel thicker and more solid than single-pane glass. But without laminated glass and hurricane-rated frames, a double-pane window can still break under flying debris or strong winds.
If you’re wondering, “Are double pane windows hurricane proof?”, the answer is only if they’re also impact-rated. Not all double-pane windows meet hurricane standards, so it’s essential to check for certification.
How Do I Know If My Windows Are Hurricane Rated?
If you’ve moved into a new home or aren’t sure what kind of windows you have, there are a few ways to tell whether they’re hurricane-rated:
- Check the glass etching: Impact windows often have a small etched label in the corner of the glass with the manufacturer’s name, certification code, and standards met (look for codes like “ASTM E1996” or “Miami-Dade NOA”).
- Ask your window installer or builder for documentation
- Check your building permit history if the windows were replaced recently
- Look at the frame construction: Impact windows tend to have thicker, reinforced frames and locking systems
Still not sure? Morgan Exteriors offers inspections to determine whether your current windows meet Florida’s hurricane requirements.
Why Choose Hurricane Window Replacements?
Beyond withstanding Category 5 storms, impact windows offer a long list of benefits that make them worth the investment even during calm weather:
- Permanent storm protection
- Increased home security against break-ins
- Better energy efficiency with insulated glass and low-E coatings
- Noise reduction for a more peaceful home
- UV protection to prevent furniture and flooring from fading
- Enhanced curb appeal with sleek designs and customizable frame options
And unlike shutters, you don’t have to do anything before a storm. Just lock your windows and you’re protected.
Are Hurricane Windows Bulletproof?
We get this question more often than you might think! The short answer is: No, most hurricane windows are not bulletproof. They are designed to resist the impact of large, fast-moving debris—not bullets. The laminated glass may slow down or absorb some bullet energy depending on the caliber and distance, but they are not certified for ballistic resistance.
If you're specifically looking for windows that offer bullet resistance in addition to hurricane protection, you'll need a specialized product that meets NIJ (National Institute of Justice) ballistic standards.
Hurricane Windows vs. Impact Windows: What’s the Difference?
When researching storm protection for your home, you’ll often see the terms hurricane windows and impact windows used interchangeably. While both are designed to withstand strong winds and flying debris, there are some key differences worth noting. Hurricane windows are specifically tested to meet Florida’s rigorous storm safety standards, while impact windows generally describe any window built with shatter-resistant glass and reinforced frames.
Understanding hurricane windows vs. impact windows can help you make a more informed choice when upgrading your home’s windows for hurricane season.
How Much Do Hurricane Window Replacements Cost in Florida?
The cost of hurricane window replacements in Florida can vary widely depending on factors like window size, frame material, glass type, and the number of windows in your home. On average, homeowners can expect to spend several thousand dollars for a full-home replacement, but the investment pays off with stronger storm protection, better energy efficiency, and increased property value.
Because every home is different, the best way to understand your potential investment is to use a reliable estimate tool. We’ve created an easy way for you to explore pricing based on your needs with out Hurricane Impact Windows Cost Calculator Guide.
