On August 19, 2020, the Jiangsu Province Built-in Shading Insulating Glass Products Industry Quality Alliance held its first 2020 work meeting in Suzhou. Nearly seventy built-in shading insulating glass production and related enterprises from the province attended the meeting, including Luo Jin, Secretary-General of Jiangsu Construction Machinery Metal Structure Association; Zhang Yunlong, President of the Window, Curtain Wall and Shading Industry Branch; Jiang Meiqin, Secretary-General of the Branch; and Lü Hui, Deputy Secretary-General of the Provincial Association. Suzhou Huadong Coating Co., Ltd., as the vice-chairman unit of the provincial association and the leader unit of the provincial built-in Venetian blind glass quality alliance, solely hosted the meeting, with General Manager Zhang Genfang presiding.

    During the meeting, representatives visited the production workshop of Suzhou Huadong Coating Glass Co., Ltd., expressing admiration for the company's large-scale production, advanced equipment, strong Technology, and well-organized on-site management.

       Zhang Yunlong introduced the purpose of the meeting, pointing out that with the promotion and application of built-in shading insulating glass products by the Provincial Housing and Urban-Rural Development Department and relevant functional departments, and through the joint efforts of enterprises, significant progress has been made in recent years. Currently, the application of this product in residential buildings in Jiangsu Province accounts for 80% or more of all building exterior shading products. However, with the continuous improvement of energy-saving policies and standards in our province, the industry faces enormous challenges. How to adapt to the development of the industry is the main issue discussed at this meeting.

  Luo Jin delivered a report on "Policy Development and Technological Innovation of High-Performance Building Exterior Windows" at the meeting, introducing the relevant content of the "Jiangsu Provincial Residential Building Thermal Environment and Energy-Saving Design Standard," "Green Building Design Standard," and "Residential Design Standard," which are currently under review by the province. During the 14th Five-Year Plan period, Jiangsu will fully implement the 75% building energy-saving standard, and the window heat transfer coefficient will be raised to a minimum standard of 1.8W/m².K, posing new challenges to building exterior windows, especially built-in shading insulating glass production enterprises. Luo Jin proposed ideas and thoughts on technological innovation of high-performance building exterior windows from six aspects: heat preservation technology, fire-resistant window technology, sound insulation window technology, integrated ventilation window technology, and standardized system window technology.

 Jiang Meiqin introduced the latest industry standard "Built-in Shading Insulating Glass Products" (JG/T255-2020). By comparing the old and new standards, she detailed the type test items and sampling requirements after the implementation of the new standard from aspects such as structural construction, performance test items, and performance parameters, and put forward suggestions on how to improve the thermal performance of built-in shading insulating glass products.

 The meeting held a heated discussion on how enterprises should correctly implement the new standard under the current situation of building energy saving. Zhongcheng Group's Ning Xiaolong, Klasses' Shen Yinrui, Jiangyin Wuyue's Huang Ting, and Huadong Coating's Zhang Genfang, the rotating leader units, successively expressed their views at the meeting, unanimously believing that improving the industry's technical level, product quality, and Brand reputation is of utmost urgency. Relevant supporting material enterprises also spoke at the meeting, hoping that built-in shading insulating glass production enterprises would use qualified supporting components to ensure product quality.

 Luo Jin made a concluding speech at the meeting, pointing out that the industry, through the form of an alliance and based on quality, has played a role in promoting the industry's progress, affirming the alliance's work and achievements, and putting forward requirements for the alliance's future work.
