Hurricane impact glass is a type of specially designed glass that offers increased resistance against high winds, flying debris, and other extreme weather conditions associated with hurricanes. It is engineered to withstand the force of storms, making it an essential component for homes and buildings in hurricane-prone areas. Unlike standard glass, which can shatter into dangerous pieces upon impact, hurricane impact glass provides a higher level of protection and security for both residential and commercial properties.
How Hurricane Impact Glass is Made
Hurricane impact glass, also known as laminated glass, consists of two or more layers of glass with a strong, clear plastic interlayer—typically polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA)—sandwiched between them. This interlayer holds the glass together even if it cracks, preventing it from shattering into large, sharp shards. This design is similar to the glass used in car windshields.
In addition to the interlayer, the glass is often tempered or heat-strengthened, which further increases its durability and resistance to breakage.
Benefits of Hurricane Impact Glass
- Storm Protection: The primary benefit of hurricane impact glass is its ability to resist the high winds and flying debris typically associated with hurricanes. Impact-resistant glass is rigorously tested to ensure it can withstand wind speeds of up to 200 mph, which can significantly reduce the risk of window breakage during storms.
- Increased Security: Besides protection from natural disasters, hurricane impact glass also provides increased security against break-ins and theft. The strength and laminated design make it much more difficult for intruders to penetrate, adding a layer of safety to homes and businesses.
- Noise Reduction: The thick, laminated structure of hurricane impact glass helps reduce outdoor noise, creating a quieter and more comfortable living or working environment.
- UV Protection: Many types of hurricane impact glass come with built-in UV filtration properties, which help block harmful ultraviolet rays. This protects your furniture, flooring, and artwork from fading due to sun exposure.
- Energy Efficiency: Hurricane impact glass is also effective at improving energy efficiency. By reducing heat transfer, it can help keep homes cooler in summer and warmer in winter, potentially lowering energy bills.
How Hurricane Impact Glass is Tested
Impact glass must pass a series of rigorous tests to be certified as hurricane-resistant. These tests include:
- Large Missile Impact Test: A 9-pound, 2×4 piece of lumber is shot at the glass at speeds of up to 50 feet per second to simulate debris impact during a hurricane.
- Small Missile Impact Test: Smaller objects, such as ball bearings, are fired at the glass at high speeds.
- Pressure Cycle Testing: The glass is subjected to repeated pressure cycles that mimic the fluctuating forces of hurricane winds.
To be classified as hurricane impact glass, the glass must not shatter or allow wind and water to pass through, even if cracks occur.
Where to Use Hurricane Impact Glass
Hurricane impact glass is ideal for homes and buildings located in regions prone to hurricanes or severe storms, especially in coastal areas. It can be used in:
- Windows
- Doors
- Skylights
- Sliding glass doors
- Storefronts
Many local building codes in hurricane-prone areas now require impact-resistant windows and doors, making this glass not only a smart choice but sometimes a legal necessity.
Conclusion
Hurricane impact glass is a crucial investment for anyone living in areas susceptible to hurricanes and severe weather. Its ability to withstand extreme forces while providing additional benefits like security, noise reduction, and energy efficiency make it an excellent choice for both residential and commercial properties.
