The main difference is that "SGP" will stay standing when both sides are broken as compared to "PVB" it will fall down or break when both sides have become damaged. The SGP laminated glass is five times stronger and up to 100 times stiffer than PVB laminated glass. That's why designers like to use SGP laminated glass for applications that face bad weather like storms, hurricanes, and cyclones, and also for some places with war or need high security.

1. Safety: SGP is designed to provide enhanced safety and security. When the glass breaks, the interlayer film holds the shattered pieces together, preventing them from falling or causing injury. This is particularly important for railings where the risk of falls from height is a concern.

2. Structural strength: SGP has exceptional load-bearing capabilities, making it suitable for structural applications. It provides stiffness and rigidity to the glass, allowing it to withstand significant wind loads, impacts, and other forces. This strength is crucial for railings to ensure they can support the weight and provide a secure barrier.

3. Durability: SGP is highly resistant to yellowing, clouding, and delamination over time. It offers excellent resistance to UV radiation, moisture, and other environmental factors. These properties make SGP laminated glass a long-lasting solution for outdoor installations, such as railings, where exposure to the elements is a concern.

4. Optical clarity: SGP has superior optical properties, resulting in high transparency and minimal distortion. This ensures that the view through the glass remains clear and unobstructed, allowing for an aesthetically pleasing and enjoyable experience for users of the railing.

5. Design flexibility: SGP laminated glass can be produced in various thicknesses and sizes, offering design flexibility for railings. It can be customized to meet specific project requirements, including curved or bent applications, allowing for creative and unique designs.
