Waterproof Back Panel

Waterproof back panel, a multifunctional composite panel in the construction industry, offers a solution for humid environments with its high-density XPS core material and fiberglass-reinforced finish. The panel features a double-sided functional layer combined with a core insulation and waterproof layer. Both sides are reinforced with alkali-resistant, high-strength fibers, while the core material uses high-pressure waterproof XBS board. Overall, it is waterproof, moisture-proof, sound-insulating, heat-insulating, flame-retardant, and easy-to-cut. The core performance parameters of the waterproof back panel are as follows: Density: 30-45 kg/m³; Water absorption (immersion in water for 96 hours): ≤1.0; Compressive strength: ≥250 kPa; Temperature range: -50℃~75℃; Fire rating: B1 (flame retardant, A grade available upon request).

Compared to traditional cement back panels and ordinary gypsum board, the core advantages of waterproof back panels are:
Waterproofing + Insulation: Integrating waterproofing and insulation, eliminating the need for additional waterproof membranes or insulation layers, saving on later construction costs;
Lightweight and Easy to Install:Despite its high strength, it is relatively lightweight, reducing the building's load-bearing burden and making transportation and installation easier. Prefabricated installation shortens the construction cycle;
High Stability:The XPS core material has strong anti-aging properties, allowing for long-term use in humid environments without the risk of cracking or dampness;
Sound Insulation and Earthquake Resistance:Excellent sound insulation effectively blocks external noise while providing earthquake resistance, maintaining structural integrity even during building vibrations and preventing cracks;
Excellent Flame Retardant Performance:Meeting Class A flame retardant standards, it slows the spread of fire in the event of a fire.

Waterproof back panels are suitable for various industry scenarios, precisely meeting the needs of different projects. In residential renovations, they can be used in damp areas such as bathrooms: as a wall baseboard, tiles or marble can be directly adhered, solving the problems of dampness in traditional brick walls and tile detachment; in kitchens, they are used on the walls behind stoves and sinks to prevent mold and blackening; in basements, waterproof back panels provide both waterproofing and insulation, preventing mold growth on walls or dampness in furniture caused by basement moisture. In commercial spaces, the durability of waterproof back panels has made them a top choice for projects, such as hotel or guesthouse bathrooms, where the product maintains its waterproof performance for a long time, reducing later maintenance costs; in shopping malls or office buildings, they prevent ground seepage from affecting lower floors; in swimming pools, they are used as baseboards for poolside walls and changing room floors, withstanding damp environments and providing insulation to reduce energy consumption.

To meet the diverse needs of different clients, our waterproof back panels offer comprehensive customization services.
