Can hurricane winds break windows?

Yes, hurricane winds have the potential to break windows due to their extreme force and pressure. The powerful winds associated with hurricanes can create a significant amount of pressure on windows, especially if they are not properly reinforced or protected. The combination of high wind speeds and flying debris can cause windows to shatter, leading to potential damage to properties and posing a risk to individuals inside. To mitigate this risk, it is crucial to install impact-resistant windows or use hurricane shutters to protect windows during severe weather events.

In the face of severe thunderstorms or hurricanes, dwellings may suffer damage or even destruction due to powerful gusts. The airborne debris can shatter windows and doors, thereby permitting the entry of strong winds into the abode. In instances of exceptionally forceful windstorms, the sheer power of the wind alone can lead to the failure of vulnerable areas within your dwelling. Scholars specializing in the study of home durability have identified four specific areas that should be inspected for potential weaknesses: windows, doors, the roof, and, if applicable, the garage door.

Within this informational document, we shall explore various measures that can be undertaken to fortify your home in anticipation of the next storm. Some of these enhancements are permanent in nature, while others are temporary solutions aimed at providing wind protection. It is of utmost importance to make the necessary preparations well in advance of an impending extreme storm. Although these endeavors, if executed correctly, can render your home more secure during a storm, they do not guarantee immunity from damage or even complete destruction. Should you receive an evacuation order, it is imperative that you comply without hesitation.

How much wind can hurricane impact windows take?

Florida residents seeking enhanced protection during hurricanes should consider installing impact windows in their homes. These windows possess the remarkable ability to withstand windblown debris, attempted break-ins, and wind speeds of up to 175 mph, equivalent to the ferocity of a Category 5 hurricane. By investing in impact windows, homeowners can alleviate concerns about their property’s safety during severe storms. To ensure a reliable installation, it is crucial to engage a reputable window installation company that specializes in impact windows.

Are hurricane windows burglar proof?
Impact windows, although not indestructible, pose a significant challenge for burglars. Breaking through these windows requires a great deal of effort and noise, increasing the likelihood of being caught. The presence of impact resistant windows eliminates the burglars’ ability to enter your home quickly and discreetly, as they prefer.

Wind speeds associated with hurricanes can cause varying levels of damage. The National Severe Storms Laboratory provides a breakdown of the potential damage at different wind speeds. At 19 mph, small trees begin to sway, while at 25 mph, using an umbrella becomes difficult and whistling can be heard through wires and branches. As the wind speed increases to 32 mph, whole trees sway and walking into the wind becomes challenging. At 39 mph, branches can break from trees and cars may veer on the road. Light structural damage occurs at 47 mph, and at 55 mph, trees can be uprooted, causing considerable structural damage. Wind speeds of 64 mph and above can result in widespread structural damage.

The Saffir-Simpson hurricane wind scale categorizes hurricanes based on their wind speeds. Category 1 hurricanes have wind speeds ranging from 74 to 95 mph. These winds can cause damage to mobile homes and trees, while well-constructed frame homes may experience minor damage to the roof or gutters. Shallowly rooted trees may topple, and power outages can occur due to damage to power lines. Additionally, a storm surge of 4-5 feet above normal can lead to coastal road flooding.

Category 2 hurricanes have wind speeds between 96 and 110 mph. These winds are extremely dangerous and can cause significant damage to homes, including roof, siding, window, and door damage. Trees are likely to sustain considerable damage and may block roads when uprooted. The storm surge during a Category 2 hurricane is typically 6 to 8 feet above normal, leading to evacuations in coastal and low-lying areas.

Category 3 hurricanes have wind speeds ranging from 111 to 129 mph. Mobile homes and poorly constructed buildings are at risk of being destroyed. The storm surge during a Category 3 hurricane is usually 9 to 12 feet higher than normal. After the storm passes, electricity and water may be unavailable for days to weeks, and major trees may be snapped or uprooted, causing significant damage to homes.

Category 4 hurricanes have wind speeds between 130 and 156 mph. These hurricanes can cause catastrophic damage, including severe damage to homes, such as the loss of the roof structure, windows, doors, and exterior walls. Areas affected by a Category 4 hurricane may be uninhabitable for weeks or months. The storm surge during a Category 4 hurricane is generally 13 to 18 feet above normal levels, and land that is less than 10 feet above sea level may be flooded.

Category 5 hurricanes have wind speeds of 157 mph or higher. These storms can destroy most homes, causing roof failure and wall collapse. The storm surge during a Category 5 hurricane is usually more than 18 feet higher than normal. Fallen trees and power lines can isolate areas, and major damage is sustained by the lower levels of all structures. Massive evacuations of residential areas are necessary, and power outages can last for weeks or months. Most of the affected area becomes uninhabitable.

The strength of windows is measured using a Design Pressure (DP) rating. Standard residential windows typically have DP values between 15 and 50. A DP 15 window can withstand winds of approximately 77 mph before shattering, while a DP 50 window can sustain winds up to 173 mph. The specific windows installed in a home depend on the building code requirements at the time of installation. It is important to note that DP values only account for wind speed and do not consider projectiles.

Miami-Dade has one of the strictest building codes in the country, particularly after Hurricane Andrew. However, it is crucial to understand that the DP rating of windows does not account for the impact of projectiles.


In conclusion, hurricane impact windows are designed to withstand the powerful forces of a hurricane and provide protection to homes and buildings. These windows are specifically engineered to resist high winds, flying debris, and extreme weather conditions. As, a leading authority in the wind power industry, we understand the importance of durable and reliable windows in areas prone to hurricanes.

When it comes to the wind speed of 100 mph, it is considered a strong wind that can cause significant damage to structures and properties. However, hurricane impact windows are designed to withstand wind speeds well beyond 100 mph. These windows are tested and certified to meet strict industry standards, ensuring their ability to withstand hurricane-force winds of up to 200 mph or more. They are constructed with reinforced frames, laminated glass, and multiple layers of interlayer material, making them highly resistant to breakage and penetration.

While hurricane impact windows provide excellent protection against the forces of nature, it is important to note that they are not specifically designed to be burglar-proof. While they may offer some level of security due to their reinforced construction, additional security measures such as locks, alarms, and security systems should be implemented to ensure complete protection against burglaries.

In conclusion, hurricane impact windows are a crucial investment for homeowners and businesses located in hurricane-prone areas. These windows provide not only protection against high winds and flying debris but also offer energy efficiency and noise reduction benefits. As, we highly recommend the installation of hurricane impact windows to safeguard properties and ensure the safety and well-being of occupants during severe weather events.
