Today, curtain walls are not only widely used in the exterior walls of the modern high-rise buildings, but also in the interior walls of buildings for a variety of functions, such as communication rooms, TV studios, airports, large stations, stadiums, museums, cultural centers, hotels, shopping malls, and etc.
Glass curtain wall has been used in construction projects 150 years ago (the mid-19th century). Due to the limitations of materials and processing techniques at that time, the curtain wall could not achieve absolute water tightness, air tightness, and resistance to various natural external forces. In practical applications, some exterior invasion (like wind, earthquake, and temperature), thermo-physical factors (heat radiation, condensation), sound insulation, fire prevention and other requirements had not been well developed and promoted at that time. So far, modern curtain wall design has been widely used in commercial and residential buildings for various purposes around the world, for curtain walls are non-structural, made of light-weight materials to reduce construction costs in building projects. In particular, glass curtain walls allow more daylight into the building, reducing the need for artificial lighting, which can save a lot of money in the long term.
In recent years, frameless glass curtain wall becomes very popular in a variety of large commercial buildings due to its full transparency and full view. It uses the transparency of glass to pursue the circulation and integration of the space inside and outside the building so that people inside the buildings can see everything outside through the glass glazing. In that regard, frameless glass curtain wall makes it possible for such a structural system to change from a pure supporting role to its visibility, thus showing the artistic, layered and three-dimensional sense of architectural decoration. Furthermore, its effect on enriching the architectural modeling and facade effect stand out from other traditional building systems. Moreover, it is the embodiment of modern technology in architectural decoration.
Benefits of Modern Curtain Wall Design
1. Because curtain wall is non-structural it can be made of a lightweight material, which to some extent, will reduce the cost of construction and installation in most cases.
2. By using structural glass curtain wall, you can allow natural light to penetrate deeper into buildings, providing improved ventilation. This also helps to reduce lighting and energy costs.
3. The wall transfers horizontal wind loads that are incident upon it to the main building structure through connections at floors or columns of the building.
4. Curtain wall is generally designed to resist air and water infiltration, sway induced by wind and seismic forces acting on the building and its own dead load weight forces.
