Hangzhou Reach Building Co.,Ltd supplies high-performance SGP Laminated Glass (SentryGlas® Plus). Composed of 2+ glass layers bonded with an SGP interlayer, it outperforms traditional PVB laminated glass—offering 4-5x higher strength, shatterproof safety, excellent acoustic insulation (32-42 STC), and durability against delamination. Suitable for facades, curtain walls, glass railings, windows, and museum displays, it supports custom sizes (150x150mm to 12000x3600mm) with a 7-day delivery time, ideal for high-security and architectural needs.
1. High Structural Stiffness
The SGP ionoplast interlayer provides significantly greater stiffness and tear strength than conventional PVB. This allows the laminated glass assembly to distribute loads more effectively and makes it suitable for large panels, minimally supported railings, façades, canopies, floors, and other structural glazing applications.
Actual load-bearing capacity depends on the glass thickness, interlayer thickness, temperature, load duration, panel dimensions, and support system. Structural calculations are required for each project.
2. Improved Post-Breakage Performance
SGP laminated glass is not shatterproof, but its interlayer helps retain glass fragments after breakage. Because the interlayer is relatively stiff, the damaged glass assembly can provide better residual stability than a comparable standard PVB configuration.
This characteristic is particularly important for overhead glazing, railings, skylights, canopies, and other locations where falling glass or loss of barrier function could create a safety risk.
3. Impact, Security, and Blast-Resistant Options
SGP laminated glass can be engineered as part of impact-resistant, security, hurricane-resistant, or blast-resistant glazing systems. Performance depends on the complete assembly, including the glass build-up, interlayer thickness, framing, fixings, sealants, and installation method.
These capabilities should only be claimed when the complete glazing system has been designed and tested according to the applicable project standard.
4. Acoustic Performance
The multilayer construction of laminated glass helps dampen vibration and reduce sound transmission. However, acoustic performance depends on the complete glass configuration rather than the use of SGP alone.
For projects where noise reduction is the main priority, asymmetric glass thicknesses, insulated glass cavities, or specialized acoustic PVB interlayers may provide better results.
5. Durability and Edge Stability
SGP interlayers provide good resistance to moisture, temperature exposure, and edge instability, supporting long-term use in demanding exterior applications. They are often selected for exposed-edge railings, façades, canopies, and humid environments.
Proper edge protection, compatible sealants, drainage, installation, and routine inspection remain necessary to maintain the performance and appearance of the laminated glass.
6. Custom Structural Glass Configurations
SGP laminated glass can be produced with tempered or heat-strengthened glass and combined with low-iron, tinted, coated, curved, printed, or insulated glass. Sizes, thicknesses, shapes, holes, notches, edges, and interlayer configurations can be customized according to project drawings and structural requirements.
