Cooperation Period: 2024

Collaborative Products: Ultra-low‑energy triple‑glazed, double‑chamber, long‑lasting sealed 4SG insulated glass, configured as follows: 6 mm clear tempered glass + 9Ar(G)TPS/4SG + 6 mm LOW‑E‑Super1+#3 tempered glass + 9Ar(G)TPS/4SG + 6 mm LOW‑E‑Super1+#5 tempered glass.

Collaborative Usage: 8,000㎡

Customer Background:

In recent years, Gumei Subdistrict in Shanghai has steadily advanced the renovation of older residential neighborhoods and the development of low‑carbon communities. In 2024, the subdistrict launched a large‑scale public‑interest project that encompasses façade refurbishment and energy‑efficiency upgrades across eight residential complexes. While preserving the original architectural character, the initiative seeks to enhance residents’ living conditions through the use of upgraded building materials, with particularly stringent requirements for the sound insulation, thermal performance, and compatibility of glazing—aimed at addressing the longstanding issues of stifling summer heat and high winter energy consumption in these aging buildings.

Solution:

In response to the project’s requirements, Huadong Coating has customized an ultra‑low‑energy, triple‑glazed, two‑chamber, long‑lasting sealed 4SG insulated glass solution. This product features a multi‑layer composite structure: 6 mm white tempered glass + 9Ar (G) TPS/4SG + 6 mm LOW‑E‑Super1+#3 tempered glass + 9Ar (G) TPS/4SG + 6 mm LOW‑E‑Super1+#5 tempered glass. By employing a dual‑seal TPS/4SG technology, it enhances airtightness; a 9 mm argon gas fill further improves thermal insulation; and a double‑silver LOW‑E coating further reduces the U‑value. The system comprehensively meets energy‑efficiency standards and structural safety requirements, ultimately supporting a total order volume of 8,000 m².

Project Outcomes:

Following project implementation, third-party testing confirmed that the glass’s thermal transmittance (U‑value) is as low as 1.2 W/(m²·K), significantly exceeding national energy‑efficiency standards and expected to reduce the building’s annual air-conditioning energy consumption by more than 30%. Meanwhile, a long‑lasting sealing technology ensures a service life of over 20 years, thereby lowering subsequent maintenance costs. According to feedback from the Shanghai Gumei Subdistrict Renovation Office, indoor noise levels in the renovated community have been reduced by more than 15 decibels, with resident satisfaction reaching 98%. This solution has established a replicable model for upgrading building materials in the subdistrict’s efforts to build low‑carbon communities.

With 32 years of dedicated expertise in the coating industry, Huadong Coating boasts a highly experienced technical team that offers comprehensive technical support, including blueprint analysis, product design, optimization solutions, and sample production.
