The application of architectural curtain wall began at the
end of the 19th century, when it was only used for a small
part of the building. By the 1950s, with the development of
construction technology, glass curtain walls began to be
applied to the building envelope on a large scale, By the
1980s, with the development of building curtain wall
technology and glass production technology and
processing technology, glass curtain walls have been more
widely used.
The total amount of China curtain walls in existing
buildings exceeds 1 billion square meters, glass facade
account over 50%,most of them are used in
skyscrapers.Here we introduce the glass panels designs for
skyscrapers.

Why glass is the
most important
curtain wall
materials in
Skyscrapers?
As a building material, glass has four major characteristics
at the same time: transparency, high strength, light
weight, and durability.

glass,why not?

Glass is a transparent material. The visible light
transmittance of clear float glass is 85-89%. Low iron glass
reduces the iron element in the glass, making it more
crystal clear and translucent, and the visible light
transmittance is increased to more than 90%.
Glass application in buildings
The light transmittance of polycarbonate board (PVC
board) can reach 75%~80%.
Thin film materials (such as ETFE) can only transmit
diffused light, but are opaque.
Glass Strength
Glass is a brittle material, but has high tensile strength.
Among the commonly used wall materials, its tensile
strength is second only to steel and much higher than
other materials.

Glass light weight
The glass bending strength is very high, especially the
tempered glass plate. Therefore, the glass panel of the
glass curtain wall is very thin,. Even if insulating glass or
laminated insulating glass composing of 2 or 3 layers of
glass, unit weight is only 40 ~ 80Kg/m2, which is much
smaller than the 350 ~ 500kgs/m2 of the concrete wall /㎡.
The glass curtain wall weight is about 1/100 of the building
total weight. This creates the necessary conditions for the
upward extension of the building height.
glass curtain wall system has light weight
Due to its high weight and low strength, stone curtain walls
are rarely used in buildings above 400m. Similarly, for
skyscrapers above 400m, architects will not choose to use

Without glass curtain walls, there would be no super-
tall skyscrapers above 500m.

1. Low iron Glass
Tempered glass has the possibility of spontaneous
explosion. Skyscraper glass facade will bring a great risk of
spontaneous explosion,and it is extremely difficult to
replace the glass after glass breakage. Therefore, effective
measures must be taken,including:
English
knowledge
glass,why not?

glass spontaneous breakage replacement-glass curtain
wall
1. Heat strengthened glass.Surface strength is lower
than tempered glass,no breakage possibility.
2. Low iron glasswith lower iron content. During
production, nickel and nickel sulfide content is also
decrease.. The spontaneous explosion rate of ultra-
white glass after tempering can be reduced to
0.0001, or even lower.
Even though low iron glass is 30% higher than clear
glass,considering the decreased future replacing costs,it’s
worthwhile to use low iron one to decrease overall costs.

2. SGP laminated glass
PVB laminated glass is currently the most widely used
glass in curtain wall.While PVB was It was originally
developed for automotive glass, not for architectural
curtain walls, so it is elastic, relatively soft, and has small
shear modulus. PVB laminated glass has small bearing
capability and large bending deformation. English
knowledge
glass,why not?

Meanwhile the exposed edges of PVB laminated glass are
easy to delaminated, after years ,glass will become yellow
color.
laminated glass-delamination-glass quality problem
For skyscraper glass,the interlayer should have below
characteristics:
1. High bonding strength,high shearing modulus.
2. High protection capability against
hurricane,earthquake,thefts, and sudden impact to
avoid collapse.
3. High sustain capability after glass breakage.
4. No color change after years.
SentryGlas Plus was invented to fulfill the high
structural laminated glass requirement in skyscraper
glass facade,large span skylight,oversized laminated
glass and all glass structural buildings.

SGP laminated glass installation

Features of SGP laminated glass:
A.High bearing capability,smaller bending deflection：
The shear modulus of SGP is more than 50 times that of
PVB, and the tear strength is 5 times higher than that of
PVB.The bearing capacity is twice that of PVB laminated
glass of equal thickness,meanwhile under the equal load
and thickness, the bending deflection of SGP laminated
glass is only 1/4 of that of PVB laminated glass.
B.Excellent edge stability
Edge stability refers to the laminated glass edges durability
exposed to atmospheric conditions. PVB glass is not
resistant to moisture, it is easy to delaminate under water
vapor. The SGP film is not sensitive to moisture, and will
not open or separate when used under exposed
conditions.So SGP laminated glass is conveniently used for
glass railings, canopy, glass fins and other exposed edge
components without special edge sealing measures.
C.High sustain capability after breakage
Once tempered laminated glass is broken, it will be bent
and deformed causing the falling off or collapsing dangers.
The risk is greater when the glass is installed horizontally
on the skylight.
English
knowledge
glass,why not?

The SGP interlayer laminated glass has good integrity.The
SGP film can bond the broken glass to form a temporary
structure after damage. The deformation is small, and it
can withstand a certain amount of load and prevent
falling.More details:

3. High performance low-E coating
insulated glass.
With the development of glass technology,energy-saving is
becoming more and more important,especially for
skyscrapers with thousands square meters glass curtain
wall,the energy used for heating and cooling is awesome.
Clear float glass U value is 5.8w/m2.k,with new double
silver low-E coating and triple silver low-E coating,double
glazed units U value can be decreased to 1.5-
1.6W/M2.K,with more energy saving measurement,such as English
knowledge
glass,why not?

filling argon into the insulated glass,and warm edge spacer
to decrease the thermal conductivity ,glass U value can be
decreased to only 1.1-1.2W/M2.K,which contribute to the
overall thermal insulation performance of the glass facade.
Thermal-insulation-glass
Function of Low-E coatings:
The low emissivity coating can reflect the far infrared
radiation directly,especially the silver layer inside the soft
coated low-E coating can reflect 98% far infrared radiation
like mirrors.
The coating has little capability absorbing the heat,which
will control the glass surface temperature very well, the
heat re-radiated out from the glass is little accordingly.
Despite controlling the infrared,the coating as a variety
options with different visible light transmittance and SC
value(0.2-0.7) to control the ratio of direct solar energy
transmitted through the glass,which can be selected by
users both in hot and cold areas.

Conclusions:
1. skyscrapers above 500m in height always use glass
curtain walls,including stick curtain wall,unitized
curtain wall.
2. Double laminated insulated glass,or laminated
insulated glass are priority for skyscrapers.Glass can

be heat strengthened ,or low iron glass to decrease
glass spontaneous breakage ratio.
3. SGP interlayer is should be considered for the middle
layer film. To improve the safety of the glass curtain
wall.
4. High performance low-E coatings-double silver low-
E,triple silver low-E coatings are applied in the
insulated glass to increase facade thermal insulation
performance.
