What are the differences between glass, stone and metal curtain walls?

Many people will choose different curtain walls. Some people like glass curtain walls, others like stone and metal curtain walls, so different curtain walls will definitely have different advantages, so let's make an analysis for you!

First, the advantages of glass curtain wall:

Glass curtain wall is a new type of contemporary wall, which endows architecture with the greatest feature of organically unifying architectural aesthetics, architectural functions, architectural energy conservation and architectural structure. The building presents different colors from different angles, giving people dynamic beauty with the changes of sunlight, moonlight and lighting. Magnificent glass curtain wall buildings have been built in major cities on all continents, such as New York World Trade Center, Chicago Petroleum Building and Sears Building. Hong Kong Bank of China Building, Beijing Great Wall Hotel and Shanghai Lianyi Building have also been adopted.

Second, the advantages of stone curtain wall:

1, natural materials, bright crystal, hard and permanent, noble and elegant.


2. Freezing resistance: Stone can resist freezing and thawing in wet state without significant damage, which is called freezing resistance. When the temperature is as low as-20℃, the water in the pores of the rock freezes, and the water in the pores expands by 1/10 larger than the original volume. If the rock cannot resist the force caused by this expansion, it will be destroyed. Generally, if the water absorption is less than 0.5%, its frost resistance is not considered.

3. Compressive strength: The compressive strength of stone will be different due to mineral composition, crystal thickness, uniformity of cementing material, load area, angle between load and cleavage and other factors. If other conditions are the same, dense materials with fine crystal particles are usually bonded to each other, which have higher strength. After being dried and saturated with water, there is no difference in compressive strength of dense volcanic rocks (the water absorption rate is extremely low). If it is a porous and water-afraid cemented rock, its dry and wet strength is significantly different.

Third, the advantages of metal curtain wall:

Leading products in metal curtain wall? Aluminum curtain? Up to now, the aluminum curtain wall in the metal curtain wall has been dominant, and the lightweight material reduces the load of the building and provides good selection conditions for high-rise buildings. Excellent waterproof, anti-fouling and anti-corrosion performance, ensuring the long-lasting growth of the external surface of the building; Processing, transportation, installation and construction are relatively easy to implement, which provides strong support for its wide use; The diversity of colors can be combined and processed into different appearance shapes, which expands the design space of architects; High performance-price ratio, easy maintenance and long service life, which meets the requirements of the owner. Therefore, aluminum curtain wall, as a kind of architectural form with great impact, is favored.
