When it comes to protecting your home from the devastating impact of hurricanes, investing in hurricane-rated windows and doors is crucial. But what do these ratings actually mean? When shopping for impact windows and doors, you will often see a lot of wording and numbers describing “hurricane ratings” and “impact ratings” and while it’s important for companies to display these ratings, they can often be difficult to understand. 

The Window Guys will walk you through the ins and outs of hurricane ratings, ensuring that you have the knowledge to make informed decisions when it comes to safeguarding your home. The next time you’re looking for hurricane windows and doors, you will feel more confident than ever!


What Are Hurricane Ratings?

  • Hurricane ratings, also known as impact ratings or design pressures, are a standardized system used to measure the resistance of windows and doors against high winds and flying debris during hurricanes or severe storms.
  • Why is it Important?: Hurricane ratings provide homeowners with a clear understanding of a product’s strength and ability to withstand extreme weather conditions, allowing them to choose the right level of protection for their homes. This is especially important when preparing for the worst storms.


Understanding the Components of Hurricane Ratings

  • Design Pressure: Design pressure is the amount of pressure a window or door can withstand without failure. It is typically measured in pounds per square foot (PSF) and indicated by three values: positive, negative, and wind load.
  • Impact Resistance: Impact resistance refers to a product’s ability to withstand flying debris without breaking. It is denoted by a specific impact rating, such as “Impact-resistant” or “Miami-Dade County Approved.”
  • Water Penetration: Water penetration rating measures a product’s ability to keep water from entering a structure during heavy rainfall. This rating is particularly important for coastal areas prone to heavy rains and storm surges.


Understanding Different Hurricane Rating Systems

  • American Society for Testing and Materials (ASTM): ASTM provides a standardized testing procedure (ASTM E1886 and ASTM E1996) to evaluate the impact resistance and design pressures of windows and doors.
  • Miami-Dade County: Known for its stringent building codes, Miami-Dade County has its own testing requirements (NOA) to ensure products can withstand the intense hurricane conditions experienced in the area.
  • Impact-Resistant Products: Impact-resistant windows and doors are labeled with various certifications, such as the “Miami-Dade County Approved” or the “Florida Building Code Approved,” indicating their compliance with the necessary hurricane standards.


Interpreting Hurricane Ratings

  • Determining the Right Rating: Understanding your local building codes, geographic location, and the level of protection required is essential in selecting the appropriate hurricane rating for your windows and doors.
  • Wind Speeds: Hurricane ratings are associated with specific wind speeds, such as 120 mph, 140 mph, or higher. Knowing the wind speed requirements for your area will help you choose the right product.
  • Code Compliance: It’s crucial to ensure that the hurricane-rated windows and doors you select comply with your local building codes and regulations to guarantee their effectiveness during storms.


Benefits of Installing Hurricane-Rated Windows and Doors

  • Protection: Hurricane-rated windows and doors provide a vital layer of protection against high winds, flying debris, and water intrusion, reducing the risk of structural damage during hurricanes or severe storms.
  • Enhanced Safety: The impact resistance of these products also helps safeguard occupants from potential injuries caused by shattered glass.
  • Energy Efficiency: Hurricane-rated windows and doors often have enhanced insulation properties, reducing heat transfer and improving energy efficiency, which can lead to lower energy bills.
  • Noise Reduction: The added thickness and strength of these products contribute to noise reduction, creating a more peaceful indoor environment.

Understanding hurricane ratings is essential for homeowners seeking to protect their homes and loved ones from the destructive forces of hurricanes. By considering the various components of hurricane ratings, interpreting them correctly, and selecting the right products, you can fortify your home against these powerful storms.
