When choosing between hidden frame curtain wall and exposed frame glass curtain wall, multiple factors need to be considered comprehensively. The following are some key considerations:

一、 Appearance requirements

1. Transparency

The hidden frame curtain wall has almost seamless connection between the glass panels in appearance, which can provide a stronger sense of transparency and integrity. If you want the appearance of the building to be highly integrated and modern, and pursue maximum vision and lighting, the hidden frame curtain wall may be a better choice.

For example, some modern office buildings and hotel lobbies often use hidden frame curtain walls to create an open and bright space atmosphere.

2. Sense of lines

The metal frame of the exposed frame curtain wall is obviously exposed, forming clear lines, which can add a certain rhythm and rhythm to the building. If the architectural design needs to emphasize the expression of lines, or hopes to create a regular and orderly appearance, the exposed frame curtain wall is more suitable.

Some buildings with industrial style or focusing on geometric shapes may choose exposed frame curtain walls to highlight their characteristics.

二、Performance requirements

1. Airtight and watertight performance

Generally speaking, the sealing performance of hidden frame curtain wall is relatively good, which can better resist the penetration of wind and rain.

However, if the sealing of exposed frame curtain wall is properly handled, it can also meet the airtight and watertight requirements of most buildings.

2. Wind pressure resistance

Due to the obvious support of the frame, the exposed frame curtain wall may have certain advantages in wind pressure resistance.

However, the specific performance needs to be determined according to the design and material selection of the curtain wall.

三、Cost factors

1. Material cost

Hidden frame curtain wall usually requires the use of special materials such as structural adhesive to fix the glass, which is relatively expensive.

The frame material cost of the exposed frame curtain wall may be relatively low.

2. Construction cost

The construction process of the hidden frame curtain wall is relatively complex, and the construction accuracy requirements are high, and the construction cost may increase.

The construction of the exposed frame curtain wall is relatively simple, and the cost may be relatively low.

四、Maintenance convenience

1. Glass replacement

The glass replacement of the exposed frame curtain wall is relatively easy because the frame is exposed and the operation space is large.

Replacing the glass of the hidden frame curtain wall is more complicated and may require professional technology and equipment.

2. Frame maintenance

The frame of the exposed frame curtain wall is easily affected by the external environment, such as corrosion, and requires regular maintenance.

The frame of the hidden frame curtain wall is hidden inside, which is more difficult to maintain, but is relatively less affected by the outside world.

For high-rise office buildings located in coastal areas, considering the importance of wind pressure resistance and sealing performance, as well as the pursuit of a simple and atmospheric appearance, they may choose an exposed frame curtain wall. And a high-end shopping mall in the city center may tend to choose a hidden frame curtain wall in order to create a fashionable and transparent shopping environment.

The final choice should be weighed based on the specific construction project needs, budget and design concept.
