New Century Grand Hotel Longgang Wenzhou

Longgang New Century Grand Hotel Wenzhou is situated at the intersection of Qiyuan Road and Yuehu Road in the central business district of Longgang City, Wenzhou, Zhejiang Province, adjacent to Yuehu Park. Invested in and developed by Longgang Hongjing Cultural Technology Co., Ltd. (a subsidiary of Hongxiang Holdings Group) with a total investment of RMB 520 million, the project occupies a site area of ​​17,450.9 square meters and has a total floor area of ​​58,134 square meters. It comprises a 34-story, super-high-rise five-star hotel, supporting facilities, and approximately 2,500 square meters of commercial space. With the tower reaching a peak height of 180 meters, it stands as a landmark building in Longgang City. The hotel features 251 luxury guest rooms and suites, a pillar-free multi-functional grand banquet hall with a ceiling height exceeding 8 meters, and comprehensive amenities including an all-day dining restaurant, a Chinese restaurant, a gym, and an indoor heated swimming pool. Designed and fitted out to five-star standards, the hotel is managed by Delong Group.

The project features a curtain wall area of ​​approximately 32,000 square meters, utilizing various systems such as framed glass curtain walls, aluminum panel curtain walls, and stone curtain walls. The building's façade cleverly incorporates elements of Longgang’s iconic lighthouse; its dynamic silhouette defines a unique city skyline, showcasing local cultural heritage while exuding the grandeur and distinctive style of a modern, fashionable hotel.

As a 180-meter super-high-rise five-star hotel located in the coastal region of southeastern Zhejiang, the Longgang New Century Grand Hotel imposes extremely rigorous requirements on its architectural glass.

Regarding safety performance, the coastal location experiences frequent high winds, necessitating exceptional wind-load resistance and impact resistance for the curtain wall glass. There are also strict specifications for the fire integrity of fire-resistant glass used in public areas and evacuation routes. In terms of energy efficiency, the hotel’s large scale and high operational energy demands require the extensive glass curtain wall to effectively control heat exchange between the interior and exterior—minimizing energy consumption for cooling and heating—while maintaining visual transparency. In terms of design and aesthetics, the hotel features a facade concept defined by sweeping curves and a soaring vertical profile. Every glass panel and structural profile is a unique, custom-made component, demanding exceptional precision in glass processing and great product versatility. Furthermore, the individual weight of the super-tall facade panels reaches up to 275 kilograms, posing a dual challenge regarding the need for both lightweight properties and structural integrity.

To meet the project's core requirements, Zhejiang Jingtai Glass Technology Co., Ltd. provided a comprehensive architectural glass solution centered on Low-E insulating glass.

Low-E insulating glass represents a strategic core product line for the company. These units feature a low-emissivity coating—composed of multiple layers of metals or other compounds—applied to the glass surface and combined with an insulating air-gap structure. This design ensures high visible light transmission while effectively reflecting mid-to-far infrared thermal radiation, thereby significantly reducing heat exchange between the interior and exterior. Specifically, the double-silver Low-E coating enables selective transmission of solar radiation; it blocks heat from entering the building in summer and minimizes indoor heat loss in winter, achieving dynamic energy efficiency. In practical applications, Low-E insulating glass has demonstrated tangible energy-saving benefits; "near-zero energy" buildings utilizing passive design strategies—such as triple-glazed, argon-filled Low-E units—achieve remarkable overall energy efficiency. Additionally, the product can be paired with body-tinted, heat-reflective, or ceramic-frit glass to create diverse color and pattern effects, fully satisfying the aesthetic requirements of the hotel's facade.

Regarding safety performance, Jingtai Glass supplies both tempered glass and tempered laminated glass for the project. Tempered laminated glass offers superior safety: even if shattered by external impact, the fragments adhere to the interlayer film rather than scattering and causing injury, making it the preferred safety material for architectural curtain walls and overhead glazing. These products have passed rigorous testing by the China Building Materials Test & Certification Center and hold "CCC" certification. To meet fire safety requirements for hotel public areas, the company offers nano-silica composite fire-resistant glass. This product is created by bonding a highly transparent, rigid nano-silica fire-resistant interlayer with glass substrates. In the event of a fire, the interlayer rapidly foams and expands to approximately ten times its original volume, forming a fire barrier that buys critical time for rescue and evacuation; it is particularly well-suited for exterior fire-resistant windows and curtain wall projects that demand exceptional weather resistance. Each unit of nano-silica composite fire-resistant glass undergoes 30 meticulous manufacturing steps over a production cycle of nearly 500 hours, ensuring high transparency and resistance to discoloration or delamination.

Regarding customized processing, Jingtai Glass has actively invested in advanced equipment—including imported fully automatic glass cutting machines, industry-leading dual-head automatic drilling machines, natural-circulation infrared heating autoclaves, and CNC straight-line double-edging machines. These investments continuously enhance precision and efficiency, enabling the precise customization of irregular and curved glass panels for various projects.

The architectural glass project for the Longgang New Century Grand Hotel represents a significant milestone for Zhejiang Jingtai Glass Technology Co., Ltd. in the high-end hotel curtain wall sector. The project not only validates the company's capacity for large-scale supply and its technical expertise in energy-efficient Low-E insulating glass but also demonstrates its comprehensive competitiveness in the custom processing of curtain wall glass for super-high-rise buildings and the provision of safety glass solutions. Successful projects like the Longgang New Century Grand Hotel have further solidified Jingtai Glass's position as a technical leader in the specialty glass deep-processing industry—both within Zhejiang province and nationwide—while providing invaluable experience for the company's continued service to the high-end architectural market.
