The core reason for using tempered laminated glass as railing partitions in high-rise buildings

1. Security guarantee

Tempered laminated glass is made by bonding two or more layers of tempered glass through an intermediate layer of PVB or EVA. When broken, fragments will be adhered by the interlayer to prevent scattering and injury, significantly reducing the risk of falling objects from high altitude. Its impact resistance far exceeds that of ordinary glass, and it can withstand high-strength impacts (such as extreme wind pressure or accidental collisions), meeting the standard requirement of high-rise buildings for vertical loads of railings ≥ 1.5kN/m. In addition, laminated glass does not require additional anti-collision railings, simplifying the structure while ensuring personnel safety.

2. Structural stability and durability

Tempered glass undergoes high-temperature quenching treatment at 700 ℃, and its bending strength is 4-5 times that of ordinary glass (≥ 100MPa). It can cope with high wind pressure (wind pressure value ≥ 3.5kPa) and temperature difference changes (-40 ℃~80 ℃) in high-rise buildings. The sandwich design further enhances the overall shear strength, making it less prone to deformation or delamination during long-term use, with a service life of over 20 years.

3. Transparency and Aesthetics

Tempered laminated glass has a transparency of over 90%, providing unobstructed views and enhancing the sense of space and lighting in buildings. Its surface can be combined with processes such as colored glaze, wire lining, or Low-E coating to meet the dual aesthetic and energy-saving needs of modern architecture (such as blocking 99% ultraviolet radiation and reducing energy consumption).

4. Standardized adaptation and convenient maintenance

According to the Technical Code for Application of building glass (JGJ 113), high-rise railing glass must adopt sandwich or sandwich hollow structure (total thickness ≥ 16.76mm) and pass 3C certification. The daily maintenance of tempered laminated glass only requires wiping with neutral detergent, and edge sealing treatment can effectively prevent water vapor penetration and reduce maintenance costs.

summarize

Tempered laminated glass has become the preferred choice for railing partitions in high-rise buildings due to its comprehensive advantages of "high strength+explosion resistance+transparency". It not only meets safety regulations, but also conforms to the pursuit of functionality and aesthetics in modern architecture.
