--- Why Choose Zhuheng Waterproof Airtight Tapes? ---
• Unmatched Quality and Performance:
Zhuheng Technology’s waterproof airtight tapes, such as the DP-in and DP-out series, are engineered with precision to deliver superior performance under extreme conditions. For example, in the Shijiazhuang Contemporary Mansion MOMA project—a landmark ultra-low energy consumption residential development—the company’s DP-in Waterproof Vapor Barrier and DP-out Waterproof Vapor Permeable Membranes were used to seal all window and pipe joints. The system achieved an air permeability rate of just 0.5 m³/(m²·h) at 50 Pa, far exceeding the national standard requirement of ≤1.0 m³/(m²·h). This exceptional airtightness not only reduced heating and cooling energy consumption by over 85% but also eliminated condensation and mold issues in humid seasons. Furthermore, the tapes demonstrated outstanding durability during a 24-month accelerated weathering test, maintaining 98% of their initial adhesion strength and showing no signs of cracking or delamination. The use of first-class raw materials, advanced multi-layer composite structures, and proprietary adhesive formulations ensures long-term stability even in harsh climates. These real-world results validate Zhuheng's claim of being born for airtightness materials—providing not just products, but proven solutions that stand the test of time.
--- Applications of Zhuheng Airtight Tapes ---
• Sealing Joints in Ultra-Low Energy Buildings:
Zhuheng’s airtight tapes are specifically designed for critical sealing points in ultra-low energy buildings where even minor leaks can compromise thermal performance. In the Beijing Tongzhou Energy Smart Command Center—the first near-zero energy building in China’s energy sector—Zhuheng’s DPad-in and DPad-out tapes were applied to seal all door and window openings, pipe penetrations, and wall joints. The project required airtightness levels equivalent to passive house standards (PHI certification), and Zhuheng’s tapes played a pivotal role in achieving this. The self-adhesive design allowed for rapid installation even in cold winter conditions (down to -10°C), significantly reducing labor time and improving construction efficiency. Additionally, the zoned release film design minimized misapplication risks, ensuring consistent bond width and integrity across thousands of joints. Post-construction blower door tests confirmed an airtightness level of 0.6 m³/(m²·h) at 50 Pa, meeting both Chinese and European standards. This case exemplifies how Zhuheng’s tapes are not just accessories but essential components in creating high-performance building envelopes.
• Versatile Use in Various Construction Projects:
Beyond ultra-low energy buildings, Zhuheng’s airtight tapes have been successfully deployed in diverse construction environments. In Shanghai Lingang New Area’s Top Scientists Community—a 180,000 m² mixed-use development featuring prefabricated panels and complex façades—Zhuheng’s DP-HD220 Special Adhesive and DPad-out tapes were used to seal joints between PC panels and curtain walls. The project faced challenges due to varying surface flatness and exposure to coastal humidity. However, the tapes’ excellent compatibility with cement mortar and resistance to aging ensured flawless integration. Similarly, in Tianjin Wuqing Xinhualian Villa Renovation, self-adhesive DPad-in tapes were used to retrofit existing homes with improved airtightness, resulting in a 40% reduction in indoor temperature fluctuations and enhanced acoustic comfort. Even in challenging projects like Zhengzhou Foreign Language School, where structural movement was expected, Zhuheng’s pre-compressed Vitaseal 300/600 tapes provided reliable expansion and sealing, preventing water infiltration during heavy rains. These real-world applications across residential, commercial, and renovation sectors demonstrate the adaptability, reliability, and universal value of Zhuheng’s airtight tape solutions.
--- Commitment to Sustainability and Innovation ---
• Contributing to Carbon Neutrality Goals:
Zhuheng Technology is deeply committed to supporting China’s dual-carbon goals. By enabling ultra-low energy consumption buildings, its airtight tapes directly contribute to reducing operational carbon emissions. For instance, in the Shijiazhuang Lihang Guantang and Tangyue Mansion project—a 110,000 m² residential benchmark in Hebei Province—the use of Zhuheng’s full-system airtightness materials helped achieve a 90% reduction in annual heating demand compared to conventional buildings. This translates to approximately 1,200 tons of CO₂ savings per year across the entire development. Moreover, the company’s products are environmentally friendly, with VOC levels below 25 g/L (well under the 100 g/L national limit), and many are recyclable. Zhuheng’s participation in drafting local standards such as DB13(J)T8503-2022 and DB13(J)T8506-2022 has helped establish national benchmarks for sustainable construction. The company’s strategic cooperation with VITA Group and inclusion in the UPPAC Technology Innovation Platform further reinforce its role in advancing green building technologies. Through these efforts, Zhuheng is not just supplying materials—it’s actively shaping a more sustainable future for the construction industry.
• Continuous Research and Development:
Zhuheng Technology’s innovation engine is fueled by deep R&D investment and collaboration. Since its founding in 2017, the company has developed over 20 proprietary products, including the NF30 and NF05 high-performance series, which feature nano-coating composite technology and modified acrylic adhesives for superior storm resistance and low-temperature performance. The launch of the DP-in ES and DP-out ES series specifically tailored for hot-summer/cold-winter climate zones reflects Zhuheng’s commitment to regional customization. These innovations were validated through extensive testing at institutions like Xi’an Jiaotong University and Huanghe Science and Technology College, where Zhuheng serves as an off-campus practical education base. The company’s participation in international exhibitions such as Fensterbau Frontale in Nuremberg, Germany, underscores its global ambition. Notably, the new Commsperm™ series has already been exported to Germany, France, and Canada, proving that Zhuheng’s R&D is not only domestic but internationally competitive. With over 200 large-scale projects completed nationwide and more than 15 million square meters of buildings protected by its systems, Zhuheng continues to push boundaries—driving the evolution of building envelope technology toward smarter, safer, and more sustainable futures.
