Oriental Yuhong GardMem Product Series Again Earns International Authority Certification with UPC and cUPC Certification in North America

The OYH GardMem series indoor waterproofing membranes have successfully passed rigorous testing and audits conducted by the International Association of Plumbing and Mechanical Officials (IAPMO), a globally authoritative certification body for plumbing and mechanical systems.In accordance with standards ANSI A118.10 “Load Bearing, Bonded Waterproof Membranes for Thin-Set Ceramic Tile and Dimension Stone Installation”, the GardMem-1000 and GardMem-2000 product lines have completed certification tests for multiple critical performance indicators, including vapor permeability resistance, anti-fungal properties, tensile strength, bonding strength, and waterproof durability. Beyond product performance, our manufacturing processes and quality control systems have also undergone stringent on-site inspections. As a result, the series has proudly earned the highly regarded Uniform Plumbing Code (UPC) and cUPC certifications for the North American bathroom and plumbing market.This achievement signifies that the GardMem series fully complies with North America's stringent regulatory requirements for safety, reliability, and environmental protection, granting it a "passport" to enter international high-end markets.

UPC and cUPC certification not only serves as an authoritative verification of the quality of bathroom and plumbing system products, but also represents standardized international safety guidelines aimed at ensuring that products used in construction and renovation can maximize user health and environmental safety. In the context of increasingly fierce competition in the global building materials market, obtaining UPC and cUPC certification has become an important reference for products to overcome technical barriers in the North American and global markets, winning customer trust, and providing strong support for brand core competitiveness.

The Significance of UPC & cUPC Certifications UPC and cUPC certifications are not only benchmarks for quality in bathroom and plumbing products but also represent standardized international safety standards. They are designed to ensure that products used in construction and renovation projects maximize user safety and environmental health. In the fiercely competitive global building materials market, holding UPC and cUPC certifications has become a crucial prerequisite for overcoming technical barriers in North American and global markets, winning customer trust, and serving as a powerful endorsement of a brand's core competitiveness.

The GardMem series bathroom waterproof and moisture-proof vapor barrier membrane from Dongfang Yuhong innovatively incorporates blocking technology, effectively preventing water vapor penetration paths. This fundamentally avoids the growth of mold and mildew caused by moisture accumulation, significantly enhancing the hygiene standards and structural durability of bathroom spaces and damp areas.

Leveraging advanced barrier technology, GardMem products effectively block vapor penetration paths, fundamentally eliminating the risk of mold and mildew growth caused by moisture accumulation. This significantly enhances the hygiene standards and structural durability of bathroom spaces and other high-humidity areas.

Specifically, Dongfang Yuhong Gardmem-1000 is a flexible and efficient waterproof and vapor barrier material, combining excellent construction convenience and adhesion strength. The product surface is equipped with precisely printed grid lines, making it easy for to quickly cut and position; at the same time, the product is remarkably flexible and has uniform thickness, allowing for seamless bonding with various substrates such as gypsum boards and cement backer boards, ensuring a strong attachment to tiles and stones. This product is widely suitable for shower areas, around bathtubs, and intermittent steam rooms, providing a solid protective barrier for household wet areas.

GardMem-1000: Flexible & Efficient Waterproofing Solution：As a versatile waterproofing and vapor retardant membrane, GardMem-1000 offers exceptional ease of installation and superior bonding strength. Its surface features precisely printed grid lines, enabling contractors to quickly cut and position the material with accuracy. The product also boasts excellent flexibility and uniform thickness, ensuring seamless adhesion to various substrates such as gypsum boards and cement backer boards, while delivering strong bonding with tiles and stone materials. Ideal for shower enclosures, bathtub surround walls, and intermittent steam rooms, GardMem-1000 provides a robust protective barrier for residential wet areas.

As a performance advanced model, Dongfang Yuhong Gardmem-2000 is specifically designed for extremely humid environments. Building on the series' high adhesion and ease of application characteristics, this product achieves a further reduction in vapor permeability. In special scenarios such as continuously used high-humidity steam baths, this product offers an outstanding vapor barrier effect that significantly surpasses that of general products, providing near-perfect sealing performance to protect substrates from moisture invasion and mold issues. Therefore, it has become the preferred choice for high-end projects that seek ultimate protective performance.

GardMem-2000: Advanced Protection for Extreme Humidity：Engineered specifically for extreme high-humidity environments, GardMem-2000 represents the next evolution in waterproofing performance. While retaining the high bonding strength and easy installation characteristics of the series, it achieves an unprecedented reduction in vapor transmission rate. For demanding applications such as continuously used steam rooms, GardMem-2000 delivers superior vapor barrier performance that exceeds standard products. Its near-perfect sealing performance protects substrates from water damage and mold infestation, making it the preferred choice for high-end projects requiring ultimate protection.
