Hurricane Impact Windows

Updated: Apr 28

Impact Windows and Doors

Impact windows are windows that are designed to withstand high winds and impact from objects. They use a heavy-duty frame and impact-resistant laminated glass with a low-emissivity coating. This makes them much less likely to shatter even from direct blows. They are crucial during hurricanes to prevent shattered windows. Impact windows come in different styles, sizes, materials, and levels of protection. They undergo standard tests to determine their level of impact resistance.

impact resistant windows

Impact windows, also known as hurricane windows, are specifically designed to resist the forces of strong winds and impacts from objects. They are constructed with reinforced frames and impact-resistant glass. The glass used in impact windows is typically laminated glass, which consists of layers of glass sandwiching a tough, transparent interlayer. This interlayer holds the glass together even if it breaks, preventing it from shattering into dangerous shards.

The purpose of impact windows is to protect areas prone to hurricanes and other severe weather conditions. During a storm, strong winds can project debris at high speeds, posing a significant risk to windows. Traditional windows are vulnerable to shattering upon impact, which can lead to further property damage and pose a danger to occupants.

In contrast, impact windows are designed to withstand these forces. The heavy-duty frame provides structural strength, while the impact-resistant laminated glass is specially designed to absorb and dissipate the energy of an impact. Additionally, impact windows often include an advanced low-emissivity coating, which helps improve energy efficiency by reducing heat transfer.

Impact windows are subjected to rigorous testing to ensure their resilience. Manufacturers simulate hurricane conditions by launching objects, such as 2x4 boards or steel balls, at high speeds toward the windows. The windows are evaluated based on their ability to withstand these impacts without fracturing or breaking apart.

If an impact window is struck by a large object, it will not shatter like traditional glass. Instead, it will form a contained spider-web pattern due to the structural integrity provided by the laminated glass and reinforced frame. This helps prevent further damage and maintains the security of the building.

Overall, impact windows are a vital component of hurricane preparedness and provide peace of mind for homeowners in hurricane-prone areas. They offer both wind resistance and impact protection, ensuring safety and reducing the risk of property damage during extreme weather events.

How Are Hurricane Windows Made?

Hurricane-rated windows are made by bonding two sheets of tempered glass with a thin plastic membrane, typically polyvinyl butyral (PVB). The thickness of the plastic membrane varies depending on the strength of the window. Most hurricane windows and doors utilize a robust aluminum frame to enhance durability and prevent the glass from dislodging upon significant impact.

Are There Different Grades of Impact Windows?

Impact windows are specifically engineered to withstand varying levels of storm intensity. They are assigned a DP rating, ranging from 0 to 50, which indicates the category of hurricane they can protect your home against. Here are some examples:

  • DP 10: Can withstand a Category 1 hurricane.

  • DP 20: Can withstand a Category 2 hurricane.

  • DP 30: Can withstand a Category 3 hurricane.

  • DP 40: Can withstand a Category 4 hurricane.

  • DP 50: Can withstand a Category 5 hurricane.

How thick is hurricane-proof glass?

The thickness of hurricane impact glass can vary between 1/4 inch to 1 1/2 inches, depending on the manufacturer. However, the majority fall between 3/16 and 1/2 inch. In comparison, regular windows typically consist of single-strength glass, which is 3/32 inch thick. This gives you an understanding of the increased strength of hurricane-impact glass.

Specifically designed for its resistance to impact, hurricane impact glass is composed of a special type of plastic called polycarbonate. This material is commonly used in bulletproof glass due to its ability to withstand impact without shattering like other plastics under pressure.

Yes, hurricane impact windows are available in the same styles as regular windows. The key difference lies in the glass used for these windows, which is specifically designed to withstand impacts and high winds. Therefore, you can purchase hurricane impact windows in various styles such as double hangs, sliders, casements, and even bay & bow windows.

Impact Windows Permit

In Florida, it is necessary to obtain a permit for the installation of impact windows. Impact windows are classified as home additions and must adhere to the state's building codes and safety regulations. Failing to obtain a permit may result in illegal installation and subsequent fines or penalties.

Benefits of Hurricane Impact Windows:

  1. Property Protection: Hurricane impact windows safeguard your home from wind, impact, and water damage during heavy storms.

  2. Resident Safety: These windows reduce the risk of injury from flying objects.

  3. Increased Home Value: Installing hurricane-impact windows can add significant value to your home, particularly in regions prone to hurricanes and tornadoes.

  4. Potential Insurance Discounts: Depending on your state of residence, installing these windows may qualify you for substantial discounts on your homeowner's insurance.

  5. Time and Energy Savings During Storms: Say goodbye to the hassle of dealing with metal shutters or accordions when preparing for a major storm. With hurricane impact windows, you can eliminate this extra effort next time a storm threatens your area!

How Do They Help to Prevent Damage?

Hurricane windows are designed to prevent glass shards from scattering and causing harm, similar to the laminated glass in car windshields. In addition, these windows must stay fully intact upon impact.

Research consistently shows that maintaining an unbroken exterior, including roofs, windows, and doors, significantly reduces storm-related damage. A broken window allows high winds to enter, creating intense pressure that can loosen or rip off the roof.

By staying in place after impact, hurricane-rated windows help keep the home’s exterior intact, making them a highly effective defense against severe storm damage. Just one broken window during a storm can lead to extensive destruction or even total loss of the home, making hurricane windows crucial for protection in such situations.

What Makes Hurricane Windows Energy Efficient? 

While laminated glass provides storm protection, it is not effective at blocking summer heat. For energy efficiency, hurricane windows often have either insulated glass or LowE coatings. The most efficient windows have both.

Insulated glass consists of an extra layer with a small gap, sometimes filled with argon gas. It functions similarly to a double-wall thermos. According to the EPA, insulated glass can reduce electric bills by over 30% compared to single-pane windows.

On the other hand, LowE glass is a silver-based coating applied to the glass itself. This coating reflects radiant heat from the sun, keeping the interior cool and comfortable. The most energy-efficient glass combines insulation with LowE technology.

What are the disadvantages of impact windows?

Impact windows can be twice as expensive as regular non-impact windows of the same size and type. Additionally, if an object strikes the laminated glass on your impact window, the glass will still crack and require replacement, although the window will prevent the object from entering the home.

Enhancing Home Security and Protection with Impact-Resistant Windows

Living in the Florida area comes with both natural beauty and potential risks such as crime and hurricanes. However, there is a solution to address these concerns - impact-resistant windows. By installing these windows in your home, you not only deter burglars but also safeguard your property from storm damage, providing you and your loved ones with peace of mind.
