Composition
Hurricane Glass Composition
Hurricane glass is typically composed of multiple layers of glass laminated together with a strong interlayer, usually made of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA). This lamination process creates a sandwich-like structure that offers increased resistance to shattering. Additionally, the interlayer provides added strength and flexibility, allowing the glass to remain intact even after impact.
Impact Glass Composition
Impact glass is also constructed using a similar lamination process. It consists of two or more layers of glass bonded together by a special interlayer, often composed of either PVB or a thermoplastic material such as polyurethane. The interlayer absorbs and distributes the force of impact, preventing the glass from breaking into sharp shards.
Strength
Hurricane Glass Strength
Hurricane glass is known for its exceptional strength and durability. The laminated construction and the use of resilient interlayers enhance its ability to withstand high winds and impact forces. This type of glass has been tested and certified to meet specific performance standards, ensuring its resistance to hurricane-force winds and the impact of debris.
Impact Glass Strength
Similar to hurricane glass, impact glass exhibits high strength and resistance to breakage. The lamination process and the interlayer significantly enhance its impact-resistant properties. Impact glass is rigorously tested to withstand the impact of varying objects, such as large rocks or baseballs, at high velocities without shattering or compromising its integrity.
