What Are Hurricane Proof Windows?
Definition
Hurricane proof windows, also known as impact-resistant windows, are specially designed windows that are built to withstand the intense winds and flying debris associated with hurricanes and other severe weather events. These windows are made with stronger materials and construction techniques compared to standard windows, offering a higher level of protection for homes located in hurricane-prone areas.
Features
One of the key features of hurricane proof windows is the use of impact-resistant glass. This glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two layers of glass, creating a strong and durable barrier. The frames of hurricane proof windows are also reinforced with materials such as aluminum or vinyl, providing added strength and stability. Additionally, these windows are equipped with sealing and anchoring systems to prevent air and water leakage, further enhancing their ability to withstand extreme weather conditions.
Benefits
The primary benefit of hurricane proof windows is the protection they offer during severe weather events. These windows are designed to withstand the impact of airborne debris, preventing it from penetrating through and causing damage to the interior of a home. By keeping the forces of wind and pressure outside, hurricane proof windows help to maintain the structural integrity of a house, reducing the risk of roof uplift and overall damage. Additionally, these windows also provide a level of sound insulation and UV protection, enhancing the comfort and energy efficiency of a home.
How Do Hurricane Proof Windows Work?
Impact-resistant Glass
The use of impact-resistant glass is a crucial component of hurricane proof windows. This glass is made by bonding layers of glass with a strong and flexible interlayer of PVB. When a high-velocity object, such as debris propelled by hurricane-force winds, strikes the glass, the interlayer helps to dissipate the force and keep the glass intact. Even if the glass does crack or shatter, it remains attached to the interlayer, preventing shards and fragments from entering the home.
Reinforced Frames
To withstand the powerful forces exerted by hurricanes, the frames of hurricane proof windows are reinforced with materials such as aluminum or vinyl. These materials offer enhanced structural support, making the windows more resistant to bending or warping. Reinforced frames also provide a tighter seal, reducing the chances of air and water leakage during storms.
Sealing and Anchoring Systems
In addition to impact resistance, hurricane proof windows are designed with sealing and anchoring systems to provide a secure barrier against the elements. These systems consist of weatherstripping, silicone sealants, and heavy-duty latches or clasps that ensure the windows remain tightly closed and intact during high winds and driving rain. The combination of impact-resistant glass and robust sealing and anchoring systems creates a comprehensive defense against hurricanes.
Multiple Layers of Protection
Hurricane proof windows offer multiple layers of protection against severe weather. The combination of impact-resistant glass, reinforced frames, and sealing systems work together to create a strong and resilient barrier. Even if one layer is compromised, such as the glass cracking, the other layers continue to provide protection and prevent further damage to the property. This multi-layered approach makes hurricane proof windows highly effective in safeguarding homes from hurricane-related hazards.

Factors That Could Lead to Hurricane Proof Window Breakage
Extreme Winds
Although hurricane proof windows are designed to withstand high winds, there are limits to the wind speeds they can endure. If a hurricane exceeds the design specifications of the windows, it can lead to window breakage. Exceptionally strong winds, gusts, or tornadoes associated with hurricanes may surpass the intended capabilities of the windows, causing them to shatter or crack.
Flying Debris
While hurricane proof windows are engineered to resist the impact of flying debris, there are instances where debris can exceed their capabilities. Large, heavy objects propelled by hurricane-force winds, such as tree branches or structural components, have the potential to cause damage to impact-resistant glass or the reinforced frames of the windows.
Improper Installation
The installation of hurricane proof windows is a critical factor in their performance and resistance to breakage. Improper installation techniques or inadequate sealing can compromise their ability to withstand hurricane conditions. Poorly sealed windows may allow wind, rain, or debris to infiltrate the home, increasing the risk of damage. It is essential to hire experienced professionals who are knowledgeable about the correct installation procedures for these specialized windows.
Structural Damage
Hurricane proof windows are designed to be installed in structurally sound buildings. If a home has pre-existing structural issues or weaknesses, such as a compromised roof or walls, the windows may not be able to withstand the forces exerted during a hurricane. In such cases, the structural damage can extend to the windows, leading to breakage or failure.
Testing and Ratings for Hurricane Proof Windows
American Society for Testing and Materials (ASTM) Standards
The American Society for Testing and Materials (ASTM) has developed rigorous testing standards to assess the performance and durability of hurricane proof windows. These standards evaluate various factors, including impact resistance, wind pressure resistance, and cycling tests. To receive ASTM certification, windows must pass these tests, ensuring they meet or exceed industry standards for strength and durability.
Miami-Dade County Testing
Another widely recognized testing and certification process for hurricane proof windows is conducted by Miami-Dade County in Florida. Due to its high susceptibility to hurricanes, Miami-Dade County has implemented stringent requirements for the performance and resistance of building components. Windows that pass the Miami-Dade County testing protocols receive a Notice of Acceptance (NOA), indicating their suitability for use in hurricane-prone areas.
Impact Resistance Levels
Hurricane proof windows are classified into different impact resistance levels based on their ability to withstand debris impact. The levels range from Level D, which offers basic protection against medium-sized debris, to Level E, which provides the highest level of impact resistance, suitable for large missile impact. The choice of impact resistance level depends on factors such as the location of the home and local building codes.
Wind Pressure Ratings
Aside from impact resistance, hurricane proof windows are also assigned wind pressure ratings. These ratings indicate the windows’ ability to withstand the positive and negative pressures associated with high winds. Windows with higher wind pressure ratings can withstand stronger wind forces without breaking or being forced inward. It is essential to consider the wind pressure requirements specific to the region when selecting hurricane proof windows.
