Top 5 Waterproof Air-tight Tapes You Need?
--- 1. Zhuheng Shield DP-in Waterproof Vapor Barrier Tape ---
• Exceptional Adhesion and Durability:
The Zhuheng Shield DP-in Waterproof Vapor Barrier Tape stands out as a premium solution in the ultra-low energy consumption building market, delivering exceptional adhesion and long-term durability. This product has been rigorously tested and successfully applied in over 200 large-scale projects across China, including landmark developments such as the Shijiazhuang Contemporary Mansion MOMA and the Shanghai Lingang New Area Top Scientists Community. In these high-performance buildings, the tape demonstrated its ability to maintain airtight integrity even under extreme weather conditions, withstanding heavy rain, wind pressure, and temperature fluctuations ranging from -40°C to 80°C. Its multi-layer composite structure, featuring a plush fabric base with high adhesive absorption, ensures seamless integration with cement mortar and other substrates. The tape’s 180° peeling strength of 1.9N/mm (tested per GB/T 2790-1995) guarantees strong initial bonding and lasting holding power, even at low temperatures. Notably, in the Beijing Tongzhou Energy Smart Command Center—the first near-zero energy consumption building in China’s energy sector—this tape was used to seal critical joints between window frames and structural walls, contributing to the building’s successful certification under both German PHI and Chinese Ministry of Housing standards. The tape’s aging resistance, corrosion resistance, and non-drying adhesive layer prevent delamination and cracking over time, significantly reducing maintenance costs and enhancing building longevity. With a water vapor diffusion resistance Sd value of 52.1m, it effectively blocks moisture migration while maintaining structural integrity. These real-world applications prove that Zhuheng Shield DP-in is not just a sealing tape—it’s a performance-driven system component engineered for reliability, quality, and sustainability in modern green architecture.
--- 2. Zhuheng Shield DP-out Waterproof Vapor Permeable Membrane Tape ---
• Flexible and High-Strength Material:
The Zhuheng Shield DP-out Waterproof Vapor Permeable Membrane Tape exemplifies innovation in breathable sealing technology, combining flexibility, high tensile strength, and superior environmental adaptability. Designed specifically for outdoor applications, this tape has been deployed in major projects such as the Qingdao Sino-German Ecopark Dejian Gongyuan and the Zhengzhou Foreign Language School, where it played a key role in preventing wall condensation, mildew, and water leakage. With a thickness of 1.25mm and a mass per unit area of 235g/m², the tape features a high-strength gray-black plush fabric base that resists punctures and mechanical damage during installation and service life. Its elongation at break reaches up to 92% transversely, allowing it to accommodate structural movement without cracking—a critical factor in dynamic environments like coastal regions or seismic zones. The tape’s water vapor permeability of 22.2g/(m²·24h) and Sd value of 2.0m ensure effective vapor diffusion control, preventing internal condensation while maintaining excellent waterproofing. In the Shanghai Shiquan Community project, one of the largest ultra-low energy consumption residential developments in central Shanghai, this tape was used on exterior wall joints and pipe penetrations, achieving full compliance with Shanghai’s upcoming 'Design Standard for Ultra-Low Energy Consumption Buildings' (to be implemented). The tape’s unique zoned release film design allows for precise, error-free application, improving construction accuracy and reducing waste. Tested under 1000mm water column for 20 hours, it remains impermeable, meeting and exceeding national standards. Its compatibility with cement mortar and resistance to UV degradation make it ideal for long-term exposure. With a proven track record in more than 15 million square meters of green building projects nationwide, the DP-out tape is a trusted choice for architects, contractors, and developers committed to sustainable, high-performance construction.
--- 3. Zhuheng Shield DPad-in Waterproof Vapor Barrier Tape ---
• High Adhesion and Easy Installation:
The Zhuheng Shield DPad-in Waterproof Vapor Barrier Tape is engineered for maximum efficiency and ease of use, making it a preferred choice in fast-paced construction environments such as prefabricated housing and modular buildings. This self-adhesive tape has been widely adopted in projects like the Tianjin Wuqing Xinhualian Villa Renovation and the Zhejiang Yuhuan Sino-German Future City, where rapid deployment and consistent quality were paramount. With a 180° peeling strength of 2.4N/mm and an elongation at break of 411% longitudinally, the tape maintains strong adhesion even under stress and thermal expansion. Its innovative zoned release film design exposes edges for controlled peeling, minimizing misapplication and ensuring clean, precise sealing—especially important in complex corner joints and tight spaces. The tape’s high-performance adhesive layer is resistant to aging, low-temperature cracking, and moisture degradation, enabling reliable performance in harsh climates. In the Shijiazhuang Lihang Guantang and Tangyue Mansion project, a 110,000 m² residential benchmark in Hebei Province, this tape was used to seal window openings and pipe penetrations, significantly reducing on-site labor time and construction errors. Compared to traditional adhesive-applied methods, the DPad-in tape cuts installation time by up to 40%, while also eliminating the need for curing periods and reducing dependency on skilled labor. Its ability to bond directly to metal, concrete, and plastic substrates without priming enhances versatility. The tape’s mass per unit area of 405g/m² and thickness of 0.61mm provide robust protection against air and water infiltration, with a water vapor diffusion resistance Sd value of 60.1m. As part of Zhuheng’s comprehensive airtightness system, this tape supports the company’s mission to reduce construction risks, improve efficiency, and contribute to carbon neutrality goals. Its success in over 200 projects nationwide confirms its status as a must-have solution for modern, high-efficiency building envelopes.
