When it comes to all-glass structures, the most commonly used elements are glass fins. These building components harness the strength and transparency of glass to create stunning architectural marvels that offer clear and uninterrupted vistas. Experience the beauty of all-glass structures with the sleek and versatile glass fins.
Glass fin detail What is a glass fin?
Glass fins are used to support glazed curtain walls and enhance their rigidity. They can also act as support for glazed roofs. In both cases, the post-breakage behavior of the glass fins is fundamental to ensuring the stability of the building.
Laminated glass, typically in multilayer constructions of three or more pieces of glass and interlayer, has been shown to function well in glass fins applications. More complex designs can involve fins multiple stories high, connected together by steel splice plates or where fins and facade glass are hung from the overhead structure.
Key points to consider:
- • Wind loading
- • Glass types for both fins and façade glass
- • Support structure for fin shoes
- • Detailing/shop drawings
- • Ease of installation
- • Building movement
Glass fin type
Toughened laminate fin for glass fin curtain wall
Glass fin eliminates the need for conventional metal mullions and beams. In curtain walls and roofs, the fin can be structurally used to transfer horizontal and vertical loads from e.g. wind and snow to the structure. Various connections can be used to transfer loads from the façade or roof light to the glass fins.
For glass fin curtain wall, Shenzhen Dragon Glass provides several different interlayer combinations based on structure and function.
✪ PVB interlayer
In case of glass breakage from human or accidental impact, the shards of broken glass will remain adhered to the interlayer providing a reduction in cutting or piercing injuries. With a properly glazed laminated glass in a framing system, fall-through protection may also be provided.
✪ Colored PVB interlayer
Colored PVB interlayers bring forth the possibility of using a large range of colors in a glass-fin curtain wall. Colored PVB interlayer permits the design of lower transmittance or intense colors without having to increase glass thickness.
✪ SGP interlayer
SGP interlayer is designed for applications where rigidity and high glass adhesion are required. Compared to the conventional PVB, this product allows:
• Laminates to be designed with reduced glass thickness
- • Enhance the post-breakage rigidity
- • High glass adhesion
- • Superior edge stability decreases the risk of delamination
- • Improved sealant compatibility
In combination with a wide range of glass types such as low-iron or colored glass or frit patterns, and different interlayer types, improves the overall performance of the glazing system and contributes to the optimum performance of the glass fin, architects have numerous possibilities.
