Impact glass, also known as hurricane glass, is a type of high-impact resistant glass designed to withstand the force of a hurricane. It is often used in hurricane shutters, which are protective barriers installed on windows and doors to prevent damage from high winds and flying debris. This article will delve into the intricacies of impact glass, its role in hurricane shutters, and the various aspects related to its usage, manufacturing, and benefits.
Understanding the importance of hurricane shutters and the role of impact glass in their construction is crucial for those living in hurricane-prone areas. These protective measures not only safeguard property but also save lives. This in-depth glossary article will explore every facet of impact glass and hurricane shutters, providing a comprehensive understanding of their significance.
What is Impact Glass?
Impact glass is a type of laminated glass that has been reinforced to withstand high-impact forces such as those generated by hurricanes. It is made by bonding two or more layers of glass with a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) in between. This interlayer acts as a strong adhesive that holds the glass layers together, even when shattered, preventing the glass from breaking into large, dangerous shards.
The process of creating impact glass involves a series of rigorous testing and quality control measures to ensure its durability and effectiveness. The glass is subjected to high-pressure and high-temperature conditions to bond the layers together, creating a single, solid piece of glass that is resistant to impact and penetration. This process, known as autoclaving, is a critical step in the production of impact glass.
Types of Impact Glass
There are two main types of impact glass: laminated glass and tempered glass. Laminated glass, as mentioned earlier, is made by bonding two or more layers of glass with an interlayer of PVB or EVA. This type of glass is highly resistant to impact and, even when broken, tends to stay together due to the adhesive properties of the interlayer.
Tempered glass, on the other hand, is made by heating the glass to a high temperature and then rapidly cooling it. This process, known as tempering, makes the glass four to five times stronger than regular glass. However, when tempered glass breaks, it shatters into small, pebble-like pieces, which can be less hazardous than large shards of glass.
What are Hurricane Shutters?
Hurricane shutters are protective coverings installed over windows and doors to protect them from the damaging effects of hurricanes. They are designed to withstand high winds and prevent flying debris from breaking the glass. Hurricane shutters come in various styles and materials, including metal, wood, and impact glass.
The primary purpose of hurricane shutters is to maintain the integrity of the building envelope during a hurricane. By preventing wind and water from entering the building, hurricane shutters can significantly reduce the risk of structural damage and personal injury.
Types of Hurricane Shutters
There are several types of hurricane shutters available on the market, each with its own set of advantages and disadvantages. The most common types include roll-down shutters, accordion shutters, Bahama shutters, colonial shutters, and storm panel shutters.
Roll-down shutters are mounted above the window and are rolled down when needed. Accordion shutters are hinged panels that fold out of the way when not in use. Bahama shutters are hinged at the top and propped open at an angle to provide shade. Colonial shutters are hinged on the sides and meet in the middle. Storm panel shutters are removable panels that are put up before a storm.
Impact Glass in Hurricane Shutters
Impact glass plays a crucial role in hurricane shutters. It provides a transparent barrier that allows light in while protecting the building from the damaging effects of a hurricane. Impact glass hurricane shutters are a popular choice due to their durability, ease of use, and aesthetic appeal.
Unlike other types of hurricane shutters, those made with impact glass do not need to be put up and taken down each time a storm threatens. They are permanently installed and provide year-round protection. This can be a significant advantage for those who live in areas where hurricanes are frequent.
Benefits of Impact Glass Hurricane Shutters
Impact glass hurricane shutters offer several benefits over other types of hurricane shutters. Firstly, they provide superior protection against wind and impact damage. The laminated construction of impact glass makes it highly resistant to shattering, and even if the glass does break, the interlayer holds the pieces together, preventing them from becoming dangerous projectiles.
Secondly, impact glass hurricane shutters are easy to maintain. They do not require the regular painting or refinishing that wood or metal shutters do. They also do not rust or corrode, making them a long-lasting option. Lastly, impact glass shutters are aesthetically pleasing. They offer a clean, modern look that can enhance the curb appeal of a home or business.
Installation and Maintenance of Impact Glass Hurricane Shutters
The installation of impact glass hurricane shutters should be carried out by a professional to ensure they are properly fitted and secure. The process involves measuring the windows or doors, cutting the impact glass to size, and installing the shutters with the appropriate hardware. It is crucial that the shutters are installed correctly to ensure they provide the maximum level of protection.
Maintenance of impact glass hurricane shutters is relatively straightforward. Regular cleaning with a mild detergent and water is usually sufficient to keep the glass clear and free from dirt and grime. It is also important to inspect the shutters regularly for any signs of damage or wear and to replace any damaged parts as soon as possible.
Conclusion
Impact glass and hurricane shutters play a vital role in protecting properties and lives in hurricane-prone areas. The use of impact glass in hurricane shutters offers superior protection, ease of maintenance, and aesthetic appeal. While the initial cost may be higher than other types of shutters, the long-term benefits and peace of mind they provide make them a worthwhile investment.
As climate change continues to intensify the frequency and severity of hurricanes, the importance of effective protective measures like impact glass hurricane shutters cannot be overstated. By understanding the intricacies of these protective measures, homeowners and businesses can make informed decisions to safeguard their properties and ensure their safety during hurricane season.
