Sika's high-performance sealing and bonding solutions enable outstanding architecture to become reality. 

One example of this is the Harbin Opera House in Northeast China, which had very special requirements in terms of its construction  and the performance of its construction materials.

Recently the cultural landmark project was recognized as one of the world’s best buildings for its outstanding architecture.

The Harbin Opera House is built to withstand hardships. Harbin, also known as “Ice City” or “Moscow in the East”, is the capital city of Heilongjiang Province in China and has approximately 5 million inhabitants.

Temperatures range from as low as -40°C in winter up to 40°C in summer. The opera house is located on the orth bank of the Songhua River where the river bed forms various curves due to constant changes in the water level.


Outstanding Architecture

The fluid formed Harbin OperaHouse, wrapped with smooth white aluminum panels  resembles a snowcapped mountain with shining ice and snow on the top - inspired by the snow and ice landscape of the city in winter.

The building, housing two theatres for 1,600 and 400 visitors respectively, opened in 2015 after five years of construction. At the beginning of this year the building received an award as one of the World’s Best Buildings by ArchDaily, the most visited architecture website worldwide.


SikaSolutions to Cope With the Harsh Climate

The extreme climate poses great challenges with respect to the building materials, including the sealants for bonding the aluminum cladding and glass facades. The sealants have to withstand the high temperature changes between winter and summer.

In winter, when the snow melting device installed at the bottom of the aluminum clad facade begins to work, the temperature of the facade will rise from the -40°Cto as high as 50°C in a very short time. Under such conditions the aluminum cladding will have a linearexpansion of up to 10cm, which must be absorbed by the Sikasil® sealants.  

Another challenge was the crystalline glass curtain wall, composed of transparent pyramids, which iswater tight, wind tight and resistant to wind pressure. The glass must be ableto withstand stress, movement and deformation after being bonded.

Sikasil®products ensure a flexible structural bonding of the facade and provide a safecurtain wall. They also prevent condensation forming within the insulating glass under lowtemperatures. Sika is proud to have contributed to the Harbin Opera House, apalace of music and art for the city which was awarded “City of Music” by UNESCO in recognition of the city’s music heritage.
