Application of Glass Fins in Modern Curtain Walls
In contemporary architectural design, large-area transparent glass curtain walls are highly favored for their expansive views and light, aesthetic appearance. The key component that supports this large transparent glass and creates a three-dimensional space is the glass fin. Also known as the "skeleton" of an all-glass curtain wall, the glass fin is a core element that maintains the stability and safety of large-span glass facades.
By definition, a glass fin is a vertical load-bearing component made of tempered or laminated glass, connected to the glass panels through structural adhesive and metal fittings. Depending on its position relative to the glass panel, it can be classified into four types: rear-mounted, joint-riding, flush, and protruding, offering great design flexibility.
Application Parameters and Standards
The technical requirements for glass fins are quite strict. In all-glass curtain walls, the thickness of a glass fin should not be less than 12mm, and the section height should not be less than 100mm – a hard requirement ensuring adequate load-bearing capacity. When the curtain wall height exceeds 4 meters or 6 meters, the glass fins must be suspended or fitted with lateral support elements to prevent buckling. Additionally, for critical joints, the PVB interlayer thickness for laminated glass fins should be no less than 0.76mm, and tempered glass fins should undergo heat soaking treatment to significantly reduce the risk of spontaneous breakage – an essential safeguard for building safety.
Key Advantages
Glass fins offer irreplaceable benefits. Traditional steel supports often appear heavy and obstructive, whereas glass fins blend indoor and outdoor spaces seamlessly, achieving an extremely transparent and unhindered visual effect. Point-supported all-glass curtain walls exhibit advantages such as high transparency, low stress distribution, and easy maintenance. With improved structural details, the connection design enhances overall stability while maintaining safety performance.
Maintenance & After-Sales Considerations
Proper maintenance is crucial for long-term performance of glass fins. During service, regular inspections should be conducted to check for looseness, damage, or abnormal sounds under wind loads. Special attention should be paid to aging of connecting bolts and sealants. If a glass fin becomes loose, it is often due to missing washers under bolts or deformed trim covers. The remedy is to remove the cover, immediately replace bolts with stainless steel ones that meet specifications, and reapply sealant.
