Description

Curtain Wall

The present invention relates to a curtain wall, and more particularly to a curtain wall that can minimize the heat transfer by conduction, convection and radiation.

In general, a curtain wall is a non-bearing wall of a building that functions to protect residents from the external environment without supporting the load of the building.

The vertical load applied to the building and the horizontal load caused by wind or earthquake are supported by the frame consisting of pillars and beams. The curtain wall does not support the load and acts as a curtain to protect the occupants in the building from the external environment.

In recent years, as the building structure is higher, curtain walls are used to construct the outer wall of the building.

Since most curtain walls are manufactured in factories, mass production is possible, and the panels forming the curtain walls can be standardized and unified. In addition, since the curtain wall is light in weight, the building's own weight can be reduced, thereby reducing the thickness of the column or beam, and light materials are used for the curtain wall to reduce the weight.

However, most of the curtain walls are treated with a glass finish on almost the entire outer wall for a beautiful appearance, resulting in poor insulation and airtightness. As a result, air conditioning and heating costs increase and condensation occurs.

On the other hand, a plastic material such as PVC or a metal such as aluminum is used as the material of the frame of the curtain wall.

Plastics have the advantage of excellent thermal insulation, but the disadvantages of the large stretch of the material itself and weak strength. In particular, the ignition temperature is low, because it has the disadvantages such as toxic gas discharge in the fire is limited in its use.

Therefore, recently, in high-rise buildings, the size of the window also has to be large, high strength, less stretch and durable metal frame, such as aluminum has been used a lot.

However, a metal frame such as an aluminum frame has disadvantages of high thermal conductivity and large heat loss due to convection.

As such, the factor that lowers the insulation performance of most curtain walls is the heat loss of the metal frame.

Window performance is estimated by the area weighted average of glass walls and curtain wall frames. In the case of glass walls, the thermal insulation performance is improved by the development of low-e glass (low-emissive glass), etc. It is possible.

On the other hand, it is not easy to solve the heat transfer problem in the metal frame.

Therefore, it is important to design the frame in the curtain wall to block heat transfer through the metal frame.
