What is the difference between point-supported and frameless installation for custom glass curtain walls processed by glass factories in Guangzhou?

There are significant differences between point-supported glass curtain walls and frameless (usually referring to a simpler form of framed curtain walls, but not completely without a frame, for ease of understanding, it is temporarily discussed in correspondence with 'point-supported') installation. These differences are mainly reflected in structural forms, glass fixing methods, component processing, installation processes, and performance characteristics.
The following is a detailed explanation of these differences:
- Structural form
Point-supported glass curtain wall:
Combines modern structural technology and glass technology designed by computer.
The curtain wall frame mainly consists of seamless steel pipes, stainless steel rods or additional cables, and stainless steel claw components.
The surface glass is connected to the supporting structure using metal connectors after being drilled at the corners.
Framed glass curtain wall (simplified form, similar to frameless):
Mostly a plane frame structure with vertical rod load-bearing systems.
Relies on high-quality aluminum profile frames and glass, with a relatively dense structure.
2. Glass fixing method
Point-supported glass curtain wall:
Glass is fixed through pre-drilled holes using stainless steel claw components.
Framed glass curtain wall:
Glass is usually bonded and fixed to the frame using structural adhesive, such as fully concealed or semi-concealed.
3. Component processing
Point-supported glass curtain wall:
Main metal components need to undergo precision processing through turning, drilling, and stamping machines.
Factory production, high installation accuracy, and good quality on-site.
Framed glass curtain wall:
Aluminum alloy components are mostly made on-site.
Processing is relatively rough, with low precision and efficiency.
4. Installation process
Point-supported glass curtain wall:
The installation process is relatively simple, first installing the aluminum frame (or metal supporting structure), then fixing the glass.
Framed glass curtain wall:
After accurately positioning the frame, the glass is installed, making the process relatively complex.
Overall installation must be carried out after the building's civil construction is completed, installing from the top down, requiring scaffolding or a hanging platform.
Point-supported glass curtain wall:
The proportion of connection points in the structure is small, with high transparency and a transparent visual effect.
The cost is relatively low, but thermal insulation and sound insulation performance may be slightly inferior to framed curtain walls.
Has a certain effect on solving urban light pollution.
Framed glass curtain wall:
The frame is wide and thick, giving a sense of stability, more suitable for minimalist style buildings.
Thermal insulation, sound insulation, and wind resistance performance are better, but the cost is higher.
Waterproofing is generally a single-layer seal, making it difficult to maintain a double-layer seal.
In summary, point-supported installation and frameless (simplified framed) installation of glass curtain walls each have their unique characteristics. The choice of installation method should comprehensively consider the type of building, usage, budget, and performance requirements.
