Sentry Glass
What is Sentry Glass?
Sentry Glass is a high-performance laminated glass product that incorporates a special SentryGlas® interlayer, which is significantly stronger and more durable than traditional PVB (polyvinyl butyral) interlayers. Sentry Glass is designed for applications requiring superior strength, security, and durability, particularly in demanding environments such as tall buildings, glass railings, and overhead glazing.
Sentry Glass Applications
- Structural glazing: Used in curtain walls and facades for high-rise buildings where additional strength and impact resistance are required.
- Glass railings and balustrades: Provides enhanced safety for frameless or minimally supported glass railings in balconies, staircases, and terraces.
- Skylights and overhead glazing: Ensures high levels of safety for overhead glass installations, where failure can be catastrophic.
- Hurricane-resistant glass: Widely used in regions prone to extreme weather, such as hurricanes, to provide extra security and impact resistance.
- Automotive and aerospace industries: Used in vehicles and aircraft where strength, weight reduction, and impact resistance are critical.
Sentry Glass Technical Specifications
- Strength: Up to five times stronger and 100 times stiffer than traditional PVB interlayers, offering superior impact resistance and structural integrity.
- Thickness: Available in various thicknesses, usually ranging from 8 mm to 25 mm, depending on the specific application.
- Durability: Resistant to UV light, moisture, and temperature fluctuations, making it ideal for outdoor and exposed environments.
- Safety: The interlayer holds the glass in place even if broken, preventing it from shattering into dangerous shards.
- Clarity: Sentry Glass offers excellent optical clarity, ensuring minimal distortion or color change over time.
Sentry Glass Production Stages
- Glass selection: The glass layers are chosen and cut to the desired size and shape.
- SentryGlas® interlayer application: The high-performance interlayer is placed between the glass sheets.
- Lamination process: The glass and interlayer are bonded using heat and pressure to create a single, strong unit.
- Quality control: The final product undergoes rigorous testing to ensure it meets strength and safety standards.
Sentry Glass Advantages
- Superior strength: Provides up to five times the strength of conventional laminated glass, making it ideal for high-stress applications.
- Long-term durability: Resists weathering, UV light, and moisture, making it a reliable choice for outdoor and exposed applications.
- Thinner and lighter: The increased strength allows for thinner glass, reducing the weight while maintaining or exceeding traditional laminated glass performance.
- Impact resistance: Protects against breakage from impacts, such as flying debris or intentional force, making it ideal for security and extreme weather conditions.
- Aesthetic flexibility: Maintains excellent optical clarity, ensuring that views are not compromised by the interlayer.
Sentry Glass Installation Guidelines
- Professional installation required: Due to its specialized nature and strength, Sentry Glass requires experienced professionals for installation.
- Correct framing and support: Ensure that appropriate framing systems are used to support the high strength of the glass.
- Regular inspection: For critical applications like railings and skylights, regular inspection is recommended to maintain structural integrity.
Comparison of Sentry Glass with Other Types of Glass
| Glass Type | Strength | Safety Features | Application Areas |
|---|---|---|---|
| Sentry Glass | Up to 5x stronger | Holds glass even if broken | High-rise buildings, railings, facades |
| Laminated Glass | Moderate | Holds glass if broken | Facades, soundproofing, safety glass |
| Tempered Glass | High | Breaks into small pieces | Doors, windows, showers |
