Company Profile

Harbin Sayyas Windows Stock Co., Ltd. was founded in 1998. As one of the enterprises to introduce German aluminum-clad wood windows with excellent performance into China, Sayyas put forward the concept of "aluminum-clad wood window", making it a new trend of the door window industry and recommended in national policies. To respond to the call of our country, and make the energy conservation and environmental protection concept of aluminum-clad wood window be known to more families, Sayyas has now created a new concept of "aluminum-clad wood air conditioning window".

Over the past 20 years, Sayyas has always been standing at the forefront of technological innovation and industrial development, has introduced high-end equipment and advanced technologies from Germany, Italy, Austria, Switzerland and other countries, and selected precious raw materials from all over the world. While constantly adhering to the national green building and building energy conservation policies, Sayyas has become the first wood window enterprise in China to be recognized as the "National Technological Innovation Demonstration Enterprise". In addition, Sayyas is also the first wood window enterprise in China to pass the certification of the Passive House Institute (PHI) in Germany and the fire protection certification of the Building Materials Test Center in Japan. Sayyas is promoting the development trend of ultra-low energy building exterior window industry in China and even the world with a number of its independently developed energy-saving window products suitable for passive buildings.

By the end of 2020, Sayyas has applied for more than 400 national patents, and nearly 20 products have obtained the certification of PHI in Germany. Sayyas leads other wooden window enterprises in China in the number of invention patents and PHI certifications. So far, Sayyas has undertaken nearly 100 passive building door and window projects in China. Its products have been exported to the United States, Canada, New Zealand, Japan, South Korea and other countries, and has served engineering projects such as Vanke, Evergrande, Poly, China Overseas, Greentown and Landsea, as well as demonstration projects, such as Sino-German Ecopark in Qingdao, Gold Dimension Passive House, Zhangjiakou Earthquake Bureau, Manzhouli Customs Office Building, and Nanjing Binjiang Development Zone Management Committee. Its products have also been widely used in high-end hotel projects.

Sayyas has established two production bases in Harbin and Nanjing. Its factory in Nangang District, Harbin covers an area of more than 30,000m2. Its factory in Shuangcheng District, Harbin covers an area of 210,000m2, including a super energy-saving passive factory. This project was designed by Rongen Architects and the Institute of Architectural Design and Research of Harbin Institute of Technology in accordance with the passive house standard. After completion, the project won the Guinness World Records for "World's Largest Passive Factory" and passed the certification of the Passive House Institute (PHI) in Germany. Its supporting office buildings have also been included in the "13th Five-Year" National Key R&D Program "Near-zero Energy Building Technology System and Key Technology Development - Public Building Demonstration Project". Its factory in Nanjing is located in Jiangning Development Zone, with a total planning area of more than 150 mu and a construction area of about 140,000m2. Phase I covers an area of 55 mu with a construction area of about 40,000m2, which will be put into operation in July 2020. In the future, Sayyas plans to build the factory in Nanjing into a world-class comprehensive and integrated "intelligent manufacturing base" for energy-saving windows.

"Keeping out climate change with aluminum-clad wood windows of Sayyas" is its consistent vision. In the future, Sayyas will continue to practice its mission, pay more attention to product development and manufacturing, and make more rooms warm in winter and cool in summer. At a time when energy consumption is severe and extreme weather occurs frequently, Sayyas aims to make its humble effort to China's energy conservation and consumption reduction and the "3060"dual-carbon goal.
