Understanding hurricane ratings for impact windows will help you make an informed decision for your home. The hurricane ratings will help you decide on what windows are suitable for your property.
If you want reliable protection, you should keep reading further to learn more in this article. We will cover what are hurricane impact ratings and the testing that impact windows go through during construction.
What Are Hurricane Impact Ratings?
A hurricane impact rating measures a window's ability to handle high-speed winds and debris. In the chaotic situation of a hurricane, the windows will need to hold up to the severe conditions that threaten your home.
These hurricane impact ratings are determined by testing laboratories that test the window frame and glass. The windows are put through rigorous tests that simulate the conditions of a hurricane.
Explanation of Design Pressure Ratings
When factoring in the hurricane impact rating, a critical measurement is the design pressure rating. The design pressure (DR) rating indicates how much wind pressure a window can withstand before failing.
Generally, a window will be DP rated between 15 to 100. The higher the number, the stronger the window against hurricane weather conditions. In many coastal areas, the building codes require windows with a minimum DP rating of 50.
Types of Impact Testing for Hurricane Windows
As part of the impact testing for hurricane windows, two primary tests determine the rating. The first is a large missile test that utilizes a large wooden beam to impact the window and test its durability.
Second, the small missile test will use steel balls to impact the window and test its durability. The windows must pass pressure testing and impact testing to achieve certification.
Performance Grade Requirements
Performance Grade ratings combine multiple factors, including air infiltration, water penetration, and structural durability. The Performance Grade should match your local area's requirements for hurricane protection.
When shopping for hurricane windows, it's crucial to pick an option with the correct Performance Grade and Design Pressure. These ratings will ensure your windows maintain effectiveness through the hurricane.
