What is Curtain Wall's view?
Curtain wall facade is a form of exterior covering of the building. This type of wall is not built like other surrounding walls and has the task of separating the exterior and interior of the building. For this reason, it is made of simple materials and, apart from reducing the dead weight of the building, it is also inexpensive.
If glass is used as a material, natural light can be used abundantly in all floors of the building. Apart from its own weight, the curtain wall does not impose any dead load on the structure. This type of wall applies horizontal wind pressure to the slab and beam and to the structure in general. In response to the question of what is the curtain wall view, it should be said that it is a view that is designed and calculated only for the resistance of the building against external atmospheric influences, fluctuations caused by wind pressure, earthquake force and the force caused by the load of the wall itself.
What is Curtain Wall's technically?
The frame and slats around the building form the curtain wall. In this view, the glass that should be considered for the facade of the building is installed on the curtain wall structure instead of the building itself. The weight caused by installing glass on the building is reduced and the resistance of the building against earthquakes increases. Nowadays, many curtain wall facades have been installed on big and famous buildings in Tehran.
The main structure and core of this façade consists of chassis and lamella, and then glass or other coverings are accurately and delicately placed on them.
What is Curtain Wall's View History?
The first samples of the curtain wall facade were made using metal or steel profiles and wood was also used as a solid component for the curtain wall. The first modern curtain wall facades were made using wood in the Ottoman Empire, where large sheets of glass began to be produced in the 18th century.
At the beginning of the 1970s, with the growth and development in the metal industry, especially aluminum, the use of this metal in construction materials was associated with success. Today, extruded aluminum profiles are used in the production of curtain wall facades. The unique properties of aluminum metal and its ability to be molded into desired shapes and designs, as well as the high flexibility of this metal when making parts during extrusion, have made this metal the main thing in curtain wall production.
What are the benefits of Curtain Wall's view?
This facade gives the buildings a modern architecture. This is a modern and economical way to cover the outer floors of the building. It does not add additional load to buildings and is placed on an independent structure. One of the main advantages of this glass facade today is that it can be created from very light materials such as glass. The use of glass in this facade provides the possibility of using a lot of natural light. It works as an insulator against heat, cold, moisture and sound. This type of glass facade significantly reduces energy consumption and reduces the costs of heating, cooling and lighting of the building. The curtain wall can be made in the form of thermal break or using double-glazed glass.
In case of fire, prevent the fire from spreading between the floors of the building.
This popular type of glass facade has a lot of flexibility in design.
Curtain wall facade can be used for small and large buildings.
In these systems, it is possible to install sensors and several fans.
What is the difference between Curtain Wall and ordinary glass facade?
In simpler terms, the main difference between these two facades is that the glass facade is structurally suspended between reinforced concrete slabs. While the curtain wall view is placed on the edge of the concrete slabs. However, there are several more complex factors that separate these views.
On the other hand, the curtain wall facade is a self-supporting facade and does not add any load to the building structure. Also, this facade is more resistant to earthquakes and weather changes (heat, cold, humidity, wind) than glass facades.
The cost of installation and execution of the curtain wall facade is approximately twice the cost of the normal double-glazed glass facade. However, the maintenance cost of curtain wall facade is cheaper.
In general, the glass facade is a better option for residential buildings. But curtain wall facades, which are installed as a unit without gaps, are good for commercial buildings where windows and balconies are rarely used.
