SGP (SentryGlas® Plus) is a specialized interlayer material used in laminated glass. It is a high-performance interlayer that offers several advantages over traditional interlayers like PVB (polyvinyl butyral) or EVA (ethylene-vinyl acetate). One layer could be 0.76mm, 0.89mm and 1.52mm. Here are some key points about SGP for laminated glass:
Enhanced strength and stiffness: SGP interlayers are known for their exceptional strength and stiffness. Compared to PVB, SGP provides up to five times the rigidity and 100 times the toughness. This increased strength contributes to the structural integrity of the laminated glass, allowing for larger glass panels and applications with higher load requirements.
Safety and security: SGP interlayers significantly improve the safety and security performance of laminated glass. In the event of breakage, the interlayer keeps the glass fragments bonded together, reducing the risk of injury from sharp shards. SGP laminated glass also offers enhanced resistance to forced entry, making it more difficult for intruders to penetrate.
Durability and weather resistance: SGP interlayers are highly durable and resistant to moisture, UV radiation, and temperature fluctuations. This makes SGP laminated glass suitable for outdoor applications, as it resists delamination, yellowing, or degradation over time. It maintains its performance and appearance even in harsh environmental conditions.
Design flexibility: SGP interlayers provide design versatility for laminated glass applications. They can be used with various glass types, colors, and thicknesses to achieve specific aesthetic or architectural requirements. SGP laminated glass can be customized to meet both functional and design objectives.
Structural applications: Due to its strength and stiffness, SGP laminated glass finds applications in structural glazing, point-fixed glass systems, and glass floors. It offers the necessary load-bearing capabilities while providing safety and design advantages.
Sound insulation: SGP laminated glass can also provide improved acoustic insulation compared to monolithic glass. The interlayer material helps dampen sound transmission, reducing noise levels and enhancing the acoustic performance of spaces.
SGP interlayers are considered a premium choice for laminated glass applications that require superior strength, safety, security, and durability. They are commonly used in architectural projects, including glass facades, balustrades, canopies, skylights, and hurricane-resistant windows. It's important to consult with glass manufacturers or professionals familiar with SGP laminated glass to determine the specific requirements and benefits for your project.
