This specialized type of glass is designed to withstand the destructive force of hurricanes, protecting homes and buildings from flying debris and strong winds. But creating glass that can withstand such extreme conditions is no easy feat, and that’s why it comes with a hefty price. From the complex manufacturing process to the rigorous testing and quality control, every step contributes to the cost of hurricane glass. So let’s dive into the fascinating world of hurricane glass and uncover the reasons behind its steep price.
Manufacturing Process
Tempering
The manufacturing process of hurricane glass begins with the tempering stage. Tempering is a heat treatment process that involves heating the glass to a high temperature and then cooling it rapidly. This process creates compressive stress on the glass surface, making it several times stronger than regular glass. Tempering also improves the glass’s resistance to impact, making it an ideal choice for hurricane-prone areas.
Laminating
After tempering, the glass goes through the laminating process. Laminating involves sandwiching a layer of polyvinyl butyral (PVB) interlayer between two layers of tempered glass. The interlayer acts as a bonding agent, holding the glass layers together even if they shatter upon impact. This allows the glass to remain intact and prevents shards from flying, providing added safety and protection during hurricanes or strong winds.
Coating
The final step in the manufacturing process is the application of special coatings. These coatings enhance the glass’s durability, strength, and resistance to scratches, while also offering additional features such as UV protection or heat insulation. The coatings used in hurricane glass undergo rigorous testing to ensure they can withstand the harsh weather conditions associated with hurricanes and tropical storms.
Materials Used
Strong and durable glass
Hurricane glass is made from strong and durable materials, such as tempered glass. Tempered glass is produced by subjecting regular glass to a process of controlled heating and rapid cooling, which increases its strength and resilience. This type of glass is designed to resist impacts and extreme weather conditions, making it an essential component of hurricane-resistant windows and doors.
Interlayers
The interlayers used in hurricane glass are usually made of polyvinyl butyral (PVB). PVB interlayers have excellent bonding properties, creating a strong bond between the glass layers. These interlayers are highly elastic and capable of absorbing and dissipating impact energy, further enhancing the glass’s ability to withstand high winds, flying debris, and other forces associated with hurricanes or severe storms.
Special coatings
To improve the performance of hurricane glass, special coatings are applied to the surface. These coatings can provide benefits like increased durability, scratch resistance, and thermal insulation. For example, some coatings are designed to reflect and absorb UV radiation, protecting the interior of buildings from harmful rays. The choice and application of coatings are crucial in ensuring the glass meets the required standards for hurricane resistance.

In areas prone to hurricanes and severe storms, there is a high demand for hurricane-resistant products, including glass. The limited supply of hurricane glass, combined with the specialized manufacturing process and materials involved, drives up the prices. Additionally, the materials used in hurricane glass, such as tempered glass and PVB interlayers, tend to be more expensive compared to regular glass, further contributing to the overall cost.
Quality Standards
Impact resistance
One of the essential quality standards for hurricane glass is its impact resistance. Hurricane glass must be able to withstand the impact of flying debris, such as tree branches or other heavy objects, during severe storms. The glass is subjected to rigorous testing, including the Large Missile Impact Test, which simulates the impact of a high-speed projectile. The ability of the glass to resist impact, prevent penetration, and maintain structural integrity is crucial for its effectiveness as a protective barrier.
Fire resistance
In addition to impact resistance, hurricane glass also needs to meet fire resistance standards. Glass used in hurricane-resistant windows and doors should have the ability to withstand exposure to fire without shattering or allowing flames to penetrate. Fire-resistant hurricane glass can help prevent the spread of fire and provide an additional layer of protection during emergencies.
Noise reduction
Hurricane glass often offers noise reduction properties, which is an additional quality standard. The interlayers used in the glass construction help dampen sound transmission, reducing external noises from entering the interior of a building. This quality makes hurricane glass a popular choice for residential and commercial buildings located in noisy areas or near highways.
