1. The Introduction of Curtain Wall
The Definition of Curtain Wall
The curtain wall is the exterior of the building envelope with no load-bearing, which looks like
a curtain hang up, and it is also known as the hanging wall. It is a modern large and tall
building with the decorative effect of the light wall. The structural framework and mosaic
sheet is formed and it doesn't assume the main structure load and effect of building envelope
structure. It is the use of a variety of strong, lightweight, beautiful building materials to replace
traditional masonry or window wall with exterior wall construction method. It is surrounded on
the main structure of peripheral so that the entire building can achieve beautiful, versatile and
safe wall method. In short, the building is put on a beautiful dress. Curtain wall scope
includes construction of walls, lighting the top (cover) and awning. The curtain walling for
building panel and the supporting structure system composition which is relative to body
structure has a certain displacement ability or certain deformation capacity, but it does not
assume the role of the main structure of building external wall.
The Characteristics of Curtain Wall
The curtain wall is an independent and complete structure system, and it is usually used in
the main structure of the lateral, and it is generally covered in the main structure on a
surface. Curtain wall is relative to the main body structure in the planar within a certain micro
ability.
The History of Curtain Wall
Architectural curtain wall has already been used as early as 150 years ago in building
engineering. At that time, due to the limitations of materials and processing technology,
curtain wall cannot reach the requirements of the absolute water tightness, air tightness,
resistance to various natural forces invasion, thermal physical factors and sound insulation,
fire protection. It has been not very good development and promotion. Since the nineteen
fifties since, due to building materials and processing technology is developing rapidly,
various types of construction materials developed, such as various sealant invention and
other insulation, fireproof filling material appearance, and it is a very good solution to building
on the periphery of the curtain wall of the requirements, and gradually become the new trend
of modern building decoration. Today, the curtain wall is not only widely used in the outer
walls of various buildings, but also applied to various features of the building interior wall,
such as the communications room, television studio, airport, station, gymnasium, museum,
cultural centre, Le Grand Large Hotel, a large shopping mall. For example the stone curtain

the corresponding global energy saving call, intelligent curtain wall, such as solar
photovoltaic curtain wall, curtain wall ventilation respiration, induction and intelligent curtain
wall, will demonstrate the unique charm of architecture.
