What is 17.52mm Sentry Glass?

17.52mm Sentry Glass refers to a specific type of laminated glass produced by SentryGlass, a brand known for its high-performance interlayer materials used in safety and security glass applications.
The 17.52mm indicates the total thickness of the glass panel, 8mm tempered glass + 8mm tempered, which typically consists of two layers of 8mm glass bonded together with SentryGlass interlayers.
What is 884 VSG factory for railing?
It refers to a specific type of laminated glass railing system that uses 884 VSG (Verbund-Sicherheitsglas). This type of glass is designed for structural applications, such as railings, balustrades, and other architectural elements where safety, durability, and aesthetics are critical.
Dragon Glass factory specializing in 884 VSG railings ensures the glass is precision-engineered and tested for safety and performance.
If you’re considering 884 VSG for a railing project, consult us to confirm the specific thickness, interlayer type, and compliance with local building codes.


Why choose 17.52mm Sentry Glass for Railing?
Choosing 17.52mm Sentry Glass for railings is an excellent decision for applications where safety, durability, and aesthetics are paramount. SentryGlass is a high-performance interlayer material used in laminated glass, and the 17.52mm thickness indicates a robust, heavy-duty glass configuration. Here are the key reasons to choose 17.52mm Sentry Glass for railings:
1. Superior Safety
- Impact Resistance: SentryGlass interlayers are significantly stronger than traditional PVB (Polyvinyl Butyral) interlayers, making the glass highly resistant to impact and breakage.
- Shatterproof: Even if the glass breaks, the interlayer holds the fragments together, preventing sharp shards from causing injury. This is especially important for railings in public spaces, balconies, or staircases.
- Compliance with Safety Standards: 17.52mm Sentry Glass meets or exceeds international safety standards for glass railings, such as EN 12600 (impact resistance) and DIN 18008 (structural glass in buildings).
2. Exceptional Strength and Durability
- Load-Bearing Capacity: The 17.52mm thickness, combined with SentryGlass interlayers, provides exceptional structural strength, making it suitable for railings that need to withstand significant loads and stresses.
- Weather Resistance: SentryGlass is highly resistant to UV radiation, temperature fluctuations, and moisture, ensuring long-term durability in outdoor environments.
- Longevity: SentryGlass interlayers are less prone to delamination or discoloration over time compared to traditional PVB, ensuring the glass remains clear and strong for years.
3. Aesthetic Appeal
- Crystal-Clear Transparency: SentryGlass maintains excellent optical clarity, allowing for unobstructed views and a sleek, modern appearance.
- Minimalist Design: The thickness and strength of 17.52mm Sentry Glass allow for frameless or semi-frameless railing designs, creating a clean and contemporary look.
- Customization: The glass can be tailored with various finishes (e.g., frosted, tinted, or patterned) to match architectural styles.
4. Versatility
- Wide Range of Applications: 17.52mm Sentry Glass is suitable for both indoor and outdoor railings, including balconies, staircases, terraces, pool surrounds, and commercial spaces.
- Compatibility with Hardware: It can be used with various railing systems, such as glass clamps, standoffs, or channels, offering flexibility in design and installation.
5. Enhanced Security
- Forced Entry Resistance: The thickness and strength of 17.52mm Sentry Glass make it difficult to break through, providing an additional layer of security for homes or commercial buildings.
- Blast and Ballistic Resistance: In high-security applications, SentryGlass can be engineered to provide protection against blasts or ballistic threats.
6. Low Maintenance
- SentryGlass is easy to clean and maintain, requiring only standard glass cleaning products to keep it looking pristine.
7. Environmental Benefits
- SentryGlass interlayers are designed to be environmentally friendly, with low VOC emissions and recyclable components.

Test Report for 8+SGP+8mm impact glass
Remove all masking and protection material from the test pieces and condition for a minimum of 12 h at (20±5)℃ before test. Each specimen was positioned in the test frame and clamped.
The tests were followed the procedures specified by BS EN12600:2002. Each specimen was hit by a test impactor at drop heights of 190 mm, 450 mm and 1200mm. The procedures were repeated for the other three specimens.
Conclusion for the testing
An impact performance test for materials in accordance with BS EN12600:2002 has been performed on the four given sample from client as described in this report. The performance classification of the all test samples is Classification 1 (C) 1.
