CASE STUDY

Soaring to an impressive height of 492

meters (1,600 feet), with 101 above-

ground floors, the Shanghai World

Financial Center (SWFC) is among

the tallest, most intricately designed

buildings in the world. The building’s

striking profile is that of a square

prism, intersected by two sweeping

arcs to form the building’s signature

opening: a vertically-evolving six-sided

shape that resembles the ancient

Chinese symbol of the earth. Here,

at 472 meters (located on the 100th

floor), the architectural vision for the

building to serve as a symbolic link

between heaven and earth is realized.

“Heaven and Earth” Is Made Possible by GE Sealants

The Challenge:

extreme Conditions necessitate high-Strength SSg Solution

An impressively large, more than 120,000 square meter (1.3 million square

feet) curtainwall system made from 10,000 four-glass-panel-unitized frames

produces the tower’s elegant profile and tapered façade, making it the

largest four-sided structural glazed curtainwall in the world. Construction of

this architectural feat posed extraordinary challenges to Gartner Shanghai

(Permasteelisa Group), the largest curtainwall fabricator in the world.

Earthquakes, typhoon-level winds, extreme weather conditions, and ultra-violet

exposure demanded an inventive structural design and an advanced silicone

structural glazing (SSG) solution.

The SoluTion:

ge SSg4400: Powerful Performance for SWFC’s

Demanding Design Requirements

After a thorough review, Gartner Shanghai selected GE SSG4400 UltraGlaze*,

a high-strength, two-part silicone elastomeric sealant/adhesive, to construct

the tower’s complex curtainwall system. With high mechanical strength and

long-term durability, flexibility and stability, SSG4400 created a lasting bond

between the glass and the SWFC’s aluminum frame, delivering a high safety

factor to the design, and exceeding the required safety guidelines by five times.

CASE STUDY

Shanghai World Financial Center

SSG4400’s fundamental properties allow it to endure severe

impact, reducing potential for damage brought on by extreme

winds, precipitation, and range of seismic activity, all quite

common in Shanghai.

Using SSG4400 also helped improve the project’s overall

production schedule. Fabrication of this impressively large

curtainwall was completed in just two years to meet the project’s

demanding timeline, thanks in large part to SSG4400’s adjustable

cure time coupled with rapid adhesion build and low pumping

pressure. These attributes supported factory conditions to allow

quicker assembly and creation of fabricated units that could then

be transported to the jobsite for erection onto the façade.

“The team of technical experts for GE sealants responded to unique

design requirements and implemented focused on-site trainings

and oversight that were instrumental in the success of this project.

Their deep expertise and attention to design and quality control

ensured that the construction of the SWFC went smoothly and was

completed two weeks ahead of schedule enabling us to cut costs

and generate income ahead of expectations,” says Daniel Choi,

Senior Project Manager, Gartner Shanghai.

ge Sealants offer System Compatibility &

Provide long-Term Sustainability

Due to the inclusion of stone on the structure, GE SCS9000 SilPruf*

NB, a 100 percent silicone, non-staining weatherproofing sealant

was chosen. As a substitute to organic sealants, SCS9000 is

formulated to reduce or eliminate dirt-pickup, surface streaking,

and substrate staining. As an excellent choice for weathersealing,

SCS9000 also provides long-term efficacy in sealing out air and

water; and the ability to withstand weather and atmospheric

conditions without degradation.

A high-performance GE silicone insulating glass sealant was also

used to seal the double-paned glazing unit (DGU) on the tower.

The sealant provides effective insulation against hot and cold

weather, increasing heating and air-conditioning efficiency and

significantly reducing the loss of energy and attendant costs,

helping in the fight to curb global warming.

30-Year history Pioneering Structural glazing

Solutions Provides Customer assurance

Distinguished by more than 30 years of pioneering silicone

structural glazing solutions, the sealants team of technical experts

offered deep category experience and a complete offering of

silicone products, known for outstanding weather resistance,

durability, adhesion, and flexibility as well as excellent performance

on complex and unique building structures around the globe.

“GE Toshiba Silicones (now GE-branded sealants) provided us with

diversified grades of sealants from which we selected the material

candidates that best met the design challenges of the SWFC,” said

Ted Graban, General Manager of Gartner Shanghai (Permasteelisa

Group). “In modern construction, the quality and technology of

the sealant materials are the keys for high-tech curtainwalls. The

team of experts behind GE sealants has a proven track record in

delivering in both categories and therefore is a trusted partner.”

The ReSulT:

Flourishing Commerce Center Becomes a global

Magnet and is named 2008 Best Skyscraper

Named 2008’s Best Skyscraper by the Council on Tall Buildings and

Urban Habitat, an international group of architects and engineers,

the SWFC is today one of the most recognized buildings in the world,

attracting some of the world’s largest and most successful financial

services firms. It’s inventive design, soaring height, and glistening

frame is a testament to the lasting efficacy of GE sealants and the

multi-faceted experience of its team of technical experts.

Thanks to the adhesive, flexible, and protective properties of GE

sealants, the SWFC’s awe-inspiring design will live among the

heavens for years to come.

experts exceed Quality Control Measures

GE sealants are only one part of this successful equation. From the

project’s inception to its completion, the deep category experience

from the sealants experts proved essential. The experts offered

critical guidance on design calculations, drawing reviews and

performed ongoing adhesion tests to meet quality control

measures. The sealants team even went a step beyond by visiting

Gartner Shanghai’s manufacturing site to train and monitor their

operators and to help start up pumping equipment.

Pioneered by ge. Refined by ge. With a history of dedication to innovation and excellence, today’s family of GE sealant products address a wide variety of

the ever-inventive, increasingly demanding architecture found around the world. Outstanding durability, flexibility, and movement capability are fundamental

to the high performance of GE sealants. With decades of experience, in new and remedial applications, on some of the world’s most innovative structures,

the sealants team provides knowledge and comprehensive support to help ensure a project is successful.
