Understanding Hurricane Rated Windows
What are Hurricane Rated Windows?
Hurricane rated windows, also known as impact-resistant windows, are specifically designed to withstand the strong winds and flying debris associated with hurricanes and severe storms. These windows are built with stronger frames, laminated glass, and other reinforcements to ensure they can withstand the intense forces and protect the property and its occupants.
Why are Hurricane Rated Windows Important?
Living in a hurricane-prone area requires taking the necessary precautions to protect your home or business from the destructive force of these storms. Windows are often the weakest points in a building’s envelope, making them vulnerable to shattering and allowing wind and water to enter. Installing hurricane rated windows is vital for maintaining the structural integrity of the building, preventing costly damage, and improving the safety of occupants during extreme weather events.
Different Types of Hurricane Rated Windows
There are several types of hurricane rated windows available, each offering varying levels of protection and functionality. The three main types include:
- Laminated Glass Windows: These windows consist of two or more layers of glass laminated together with a durable interlayer, typically made of polyvinyl butyral (PVB). The interlayer holds the glass together even if it shatters, preventing it from breaking apart and forming dangerous shards. Laminated glass windows provide excellent impact resistance and are often combined with reinforced frames to enhance their overall strength.
- Multi-Layered Construction Windows: These windows are designed with multiple layers of glass, sometimes with a layer of plastic or acrylic sandwiched in between. The additional layers offer increased impact resistance and strength, making them suitable for areas with high wind loads.
- Thicker Frames: Hurricane rated windows with thicker frames are specifically engineered to withstand higher wind pressures. These frames are often made of durable materials such as aluminum, vinyl, or fiberglass that are reinforced for added strength. Thicker frames provide improved resistance against wind and debris, making them a popular choice for hurricane-prone regions.
Certification and Testing
Impact Testing
To ensure the reliability and effectiveness of hurricane rated windows, they undergo rigorous impact testing. In these tests, large projectiles, such as wooden planks or steel balls, are propelled at high speeds towards the window to simulate flying debris during a hurricane. The windows are evaluated based on their ability to withstand multiple impacts without compromising their integrity.
Design Pressure Ratings
Hurricane rated windows are assigned design pressure ratings, which indicate their ability to withstand the forces exerted by wind. These ratings are expressed in pounds per square foot (psf) and include both positive and negative values to account for the different pressures experienced inside and outside of the building during a storm. Higher design pressure ratings signify windows that are better equipped to withstand stronger winds.
Certification Labels
Approved hurricane rated windows bear certification labels from recognized testing and certification organizations, such as the Miami-Dade County Product Control Division or the Florida Building Code (FBC) Miami-Dade Hurricane Test Protocol. These labels provide assurance that the windows have met the required standards and have undergone extensive testing to verify their performance in hurricane conditions.
Visual Indications
Laminated Glass
Laminated glass is a common feature in hurricane rated windows. By holding the glass layers together, even when shattered, laminated glass provides a crucial safety advantage by reducing the risk of injury from flying shards. You can identify laminated glass windows by their distinctive appearance, which may include a slight tint from the interlayer or visible layers when looking at the edge of the glass.
Multi-Layered Construction
Windows with multi-layered construction often have a thicker appearance due to the additional layers of glass or plastic/acrylic. These layers make the windows more robust and resistant to impact, providing an extra layer of protection against windborne debris. When visually inspecting a window, you may notice the slight variation in thickness compared to traditional windows.
Thicker Frames
Hurricane rated windows with thicker frames are designed to withstand higher wind pressures, providing enhanced protection. These frames are often more substantial and have reinforcements or strategically placed bracing to increase their strength. When examining a window, you may notice the thicker frame profile compared to standard windows, particularly at the corners or along the edges.
Installation Considerations
Proper Anchoring
Installing hurricane rated windows requires proper anchoring to ensure their effectiveness during a storm. The windows need to be securely fastened to the structural framing of the building using appropriate fasteners and anchors. The type and spacing of the anchors should follow the manufacturer’s guidelines and meet local building codes to ensure sufficient support and resistance to wind loads.
Reinforced Frames
In addition to proper anchoring, hurricane rated windows often require reinforced frames to maximize their strength and resistance against wind pressures. Reinforcements can include internal braces, corner gussets, or steel or aluminum rods embedded in the frames. These reinforcements help distribute the forces evenly to prevent frame failure and maintain the window’s integrity under severe weather conditions.
Sealants and Weatherstripping
Sealants and weatherstripping play a crucial role in the installation of hurricane rated windows. Proper application of sealants around the window frame creates an airtight and watertight seal, preventing wind-driven rain from entering the building. Weatherstripping helps improve the overall energy efficiency of the window and reduces air and water infiltration. Both sealants and weatherstripping need to be selected and applied correctly to ensure optimum performance.
