--- 1. Zhuheng Shield DP-in Waterproof Vapor Barrier Tape ---
• Overview and Features:
Zhuheng Shield DP-in Waterproof Vapor Barrier Tape stands out as a premium solution in the ultra-low energy consumption building sector, developed by Hebei Zhuheng Technology Co., Ltd., a pioneer in airtightness materials since 2017. Engineered with first-class raw materials and a multi-layer composite structure, this tape delivers exceptional performance in both durability and ease of installation. Its key feature lies in its dual-adhesion system: one side uses a super-strong adhesive tape for bonding to window frames, while the other side is secured using the specialized DP-HD200/210/220 adhesive, ensuring long-term stability and resistance to aging, temperature fluctuations, and mechanical stress. The product boasts a thickness of 0.65mm, a mass per unit area of 215g/m², and a tensile strength of up to 726N/50mm longitudinally—exceeding national standards such as DB13(J)/T8503-2022. With an Sd value of 52.1m, it provides superior vapor barrier performance, effectively blocking water vapor diffusion and minimizing thermal bridging. The plush fabric base ensures excellent adhesion to cement mortar, enabling seamless integration into plastered surfaces. Notably, it complies with occupational health and safety standards, making it environmentally friendly and safe for indoor use. This tape has been successfully deployed in over 200 large-scale projects nationwide, including Shijiazhuang Contemporary Mansion MOMA and Shanghai Lingang New Area Top Scientists Community, where its reliability under harsh weather conditions was validated during winter installations.
• Applications and Benefits:
The Zhuheng Shield DP-in Waterproof Vapor Barrier Tape is specifically designed for sealing internal joints in ultra-low energy consumption buildings, including door and window openings, pipe penetrations, floor joints, and structural connections between primary and secondary components. It excels in areas prone to condensation and mold, such as interior wall junctions and utility chases. One of its most significant advantages is its ability to maintain airtight integrity even in complex or irregularly shaped joints, thanks to its flexibility and high elongation at break (37%). In real-world applications like Beijing Tongzhou Energy Smart Command Center—the first near-zero energy consumption building in China’s energy sector—the tape played a critical role in achieving PHI certification by ensuring consistent airtightness across all window and door interfaces. Its self-peeling strength and resistance to delamination prevent long-term degradation, reducing maintenance costs and enhancing building longevity. Additionally, the tape’s low-temperature resistance allows installation even in northern China during winter months when temperatures drop below freezing, a major benefit in regions like Tianjin and Shandong. By combining high-performance materials with user-friendly design, Zhuheng Shield DP-in not only improves construction efficiency but also contributes directly to carbon peaking goals by minimizing heat loss and improving energy efficiency. Its proven track record in green building certifications—including three-star green buildings and national quality engineering awards—makes it a trusted choice for architects, contractors, and developers committed to sustainable construction excellence.

• Performance Characteristics:
Zhuheng Shield DP-out Waterproof Vapor Permeable Membrane Tape is a breakthrough product engineered for outdoor application in ultra-low energy consumption buildings, offering a balanced combination of waterproofing and vapor permeability. Manufactured from high-strength, aging-resistant plush fabric with a unique multi-layer composite structure, this tape features a water vapor transmission rate of 1.7×10⁻⁵g/(m²·s·Pa) and an Sd value of just 0.1m, ensuring that moisture can escape while blocking rainwater intrusion. Its longitudinal tensile strength reaches 132N/50mm and transverse strength hits 399N/50mm, far exceeding the minimum requirements set by national standards such as GB/T 328.9-2007. The tape’s 1.75mm thickness and 235g/m² mass provide robust protection against mechanical damage and UV exposure. One of its standout features is the 20mm-wide high-performance adhesive layer with excellent initial adhesion and low-temperature resistance, allowing reliable bonding even at -10°C. The tape also exhibits outstanding durability: after immersion and thermal aging tests, no delamination or cracking was observed, confirming its long-term stability. Tested under 1000mm water column for 20 hours, it remains impermeable—meeting the stringent criteria of the CECS Association Standard and Hebei Province’s DB13(J)/T8506-2022. Furthermore, its 180° peeling strength of 1.6N/mm ensures secure attachment to diverse substrates like concrete, steel, and aluminum. These attributes make it ideal for sealing exterior joints exposed to extreme weather conditions, especially in coastal and humid climates.
• Ideal Use Cases:
This tape is ideally suited for sealing outdoor door and window openings, pipe penetrations through external walls, and joints between steel components and façades in high-performance buildings. It is particularly effective in projects requiring compliance with passive house standards, such as Qingdao Sino-German Ecopark Dejian Gongyuan and Zhejiang Yuhuan Sino-German Future City Project, where it was used to protect against wind-driven rain and condensation. In these environments, the tape prevents moisture accumulation behind insulation layers, which could otherwise lead to mold growth and structural degradation. Its compatibility with the DP-HD220 adhesive ensures a continuous, seamless seal system. The tape is also widely used in prefabricated buildings and curtain wall systems, where it maintains airtightness during assembly and throughout the building lifecycle. For example, in Shanghai Pengrui Yunjing Bay—a landmark project covering 180,000 square meters—the DP-out tape was applied along all exterior window joints, contributing to the building’s achievement of national high-quality engineering status. Its zone-exposed release film design enhances precision during installation, reducing errors and rework. Moreover, due to its environmental compliance (VOC < 21g/L), it meets strict indoor air quality regulations, making it suitable for residential and commercial spaces alike. Whether used in cold northern regions or hot southern climates, this tape consistently delivers superior performance, proving itself as a cornerstone of modern airtight construction.
