At a glance, a heavy-duty security screen and a see-thru hurricane barrier can look almost identical: a strong frame holding a perforated or mesh panel over a window. But they are designed against different threats, tested in different ways, and installed for different reasons. Understanding the differences helps you choose a product that actually protects against the risks you face, and shows when a single product can cover both.
What Security Screens Are Designed to Stop
Security screens protect against people. Their job is to resist forced entry, such as prying, cutting, kicking and attempts to remove the screen, long enough to deter or delay an intruder. They also stop thrown objects such as rocks from breaking glass, and can prevent items being passed through window openings. Key features include strong infill that resists cutting, frames that resist prying, tamper-resistant fasteners and secure locking hardware.
Security screens are commonly used on ground-floor windows, schools, public housing, government buildings, pharmacies and other sites where break-ins or vandalism are a concern.
What Hurricane Barriers Are Designed to Stop
Hurricane barriers protect against nature. They must resist the impact of wind-borne debris, such as a 2x4 thrown by the wind, and then hold up under thousands of cycles of positive and negative wind pressure. They must stay far enough from the glass that they do not break it when they flex, and their anchors must hold against strong suction. Products for hurricane regions are tested to standards such as ASTM E1886/E1996 or the Florida TAS protocols and carry approvals listing the sizes and pressures they cover. See ASTM E1996 missile levels.
Key Differences
| Aspect | Security screen | Hurricane barrier |
|---|---|---|
| Main threat | Intruders, vandals, thrown objects | Wind-borne debris and wind pressure |
| Typical testing | Forced entry and attack resistance | Missile impact plus cyclic pressure |
| Critical design point | Resisting cutting and prying, secure locks | Absorbing impact, anchoring against suction |
| Time in place | All year | All year or only during storms, depending on style |
| Approval documents | Varies by market | Product approvals such as Miami-Dade NOA |
The important takeaway: a strong security screen is not automatically a hurricane barrier. Unless it has been tested and approved for impact and wind pressure, it should not be relied on as hurricane protection. Likewise, a storm panel that is only installed before hurricanes provides no security the rest of the year.
Products That Do Both
Some products are engineered and tested for both roles. Exeter Architectural Products began with the CRIME SHIELD security barrier, the first in the industry to combine heavy-duty perforated metal with reinforced extruded aluminum framing, hinges and quick release locking mechanisms. After Hurricane Andrew, Exeter refined that design into STORM SHIELD Hurricane Barriers, adding the impact and wind performance required for hurricane protection. Because the barrier stays in place year round, it works as a security screen every day and as a hurricane shutter when a storm arrives. Exeter has noted that in some cases the cost of the system can be justified by glass breakage savings alone.
Combining both functions in one product has practical advantages:
- One installation instead of two separate systems on each window.
- Protection that is always in place, with no storm-day setup for permanent styles.
- A consistent appearance across the building.
- Daylight, views and shade from the see-thru perforated panel.
Where the Threats Overlap
Security and storm risks often show up in the same places. Coastal homes and condominiums may sit empty for months, which makes them targets for break-ins and leaves no one available to install shutters when a storm forms. Schools and public buildings face vandalism year round and are often used as shelters during hurricanes. After a storm, damaged neighborhoods can see an increase in looting while power is out and residents are away. In each of these situations, a barrier that is always in place and resists both intruders and debris covers gaps that a single-purpose product would leave open. That is one reason permanent see-thru barriers have been popular for public buildings and seasonal residences.
Don't Forget Emergency Exit
The biggest risk of any window security product is trapping occupants in a fire. A combined security and hurricane barrier on a bedroom, dormitory or other escape opening should have a release that works from inside without keys, tools or special knowledge. STORM SHIELD's optional security egress latch turns the barrier into an easily egressable security screen as well as a hurricane shutter, opening with a one-point release for quick exits.

Questions to Ask
- Has the product been tested for hurricane impact and cyclic pressure, and at what missile level?
- Does it carry a current product approval for my opening sizes and wind pressures?
- How does it resist forced entry: infill, frame, fasteners and locks?
- Can it be locked against intruders but released from inside for escape?
- Will it be in place all year, or must it be installed before storms?
- How does it look, and does it preserve light and views?
Choosing for Your Building
Start by listing the threats each opening faces and how the building is used throughout the year. If your only concern is break-ins in a region with no hurricane risk, a dedicated security screen may be enough. If you face both security and hurricane risks, a single product tested for both can be the most efficient solution. For buildings with a mix of needs, use combined barriers where both threats apply and choose other styles elsewhere. Exeter's related SECURITY SHIELD window barriers focus on security applications.
Conclusion
Security screens and hurricane barriers address different threats, and a product designed for one is not automatically suitable for the other. When a barrier has been engineered and tested for both, and includes a safe inside release where needed, it can protect a building from intruders and storms every day of the year while keeping windows bright.
