Product Details
Moisture-proof WPC wall panel
,Great Wall shape interior panel
,160x20mm WPC wall covering
The Moisture-Proof 160x20mm Great Wall Shape WPC Interior Wall Covering is an advanced engineering-grade wall decoration material designed specifically for high-humidity environments, luxury commercial spaces, and modern residential interiors. Manufactured through high-pressure thermal extrusion using high-purity wood fiber, thermoplastic polymers, and moisture-resistant stabilizing additives, this product solves the common industry challenges of molding, warping, and cracking found in traditional timber and MDF paneling.
Featuring a distinctive 160x20mm Great Wall profile, it imparts a striking 3D geometric light-and-shadow effect to interior walls. Engineered for long-term operational stability, our wall covering combines superior damp-resistance, structural rigidity, and natural wood texture—providing global architects, contractors, and building material importers with a durable, low-maintenance, and easy-to-install architectural wall solution.

- Exceptional Moisture & Mold Resistance: Features a closed-cell polymer encapsulation structure with ultra-low water absorption (≤ 0.5%). It will not swell, mold, or peel even during humid seasons, coastal dampness, or basement applications.
- 3D Great Wall Geometric Aesthetics: The engineered 160x20mm Great Wall profile creates dynamic 3D geometric shadow effects under interior lighting, significantly enhancing spatial depth and texture.
- High-Density Structural Rigidity: The 24mm profile depth combined with internal reinforcing ribs provides exceptional flexural modulus (≥ 2500 MPa) and impact strength, effectively masking sub-wall surface imperfections.
- E0 Eco-Friendly Standard: Produced with eco-conscious raw materials and lead-free stabilizers, the product meets strict formaldehyde emission limits, enabling immediate post-installation occupancy without toxic fumes.
- Hidden Fastener Interlocking System: Features a precision tongue-and-groove joint design paired with hidden clips, eliminating visible surface screw holes for faster installation and a seamless finish.
- High-Humidity Interior Zones: Enclosed balcony walls, basement media rooms, indoor pool lounges, and spa corridors.
- Commercial & Executive Spaces: Corporate reception backdrops, boardroom feature walls, retail brand store interiors, and hotel corridor wainscoting.
- Residential Interior Design: Living room TV background walls, entryway partition walls, bedroom headboard features, and hallway wainscoting.
- Public Facilities & Educational Institutes: Library reading areas, art gallery exhibition walls, and upscale restaurant dining rooms.
Traditional MDF or real wood paneling absorbs atmospheric moisture through open pores, causing swelling and mold. The Moisture-Proof 160x20mm Great Wall Shape WPC Interior Wall Covering utilizes high-temperature extrusion to fully encapsulate wood fibers within polymers, forming a non-porous closed-cell matrix. Tested under ASTM D570 standards, its 24-hour water absorption rate remains below 0.5%, fundamentally blocking water vapor ingress and ensuring long-term moisture and mold resistance.
The 160x20mm Great Wall profile creates rich angular surfaces. The geometric cross-section scatters indoor sound waves to help dampen echoes and lower ambient noise. Visually, the 20mm dimensional depth interacts with ambient light to produce natural vertical shadows that break up flat, monolithic wall surfaces.
On smooth, dry indoor walls, panels can be directly installed using construction adhesive combined with hidden starter clips. If the sub-wall is damp or uneven, installing light steel or WPC battens (spaced 300mm to 400mm apart) is recommended. Once the initial panel is fixed, subsequent panels interlock via the tongue-and-groove lip and are secured to the battens with hidden screws, ensuring a clean face with no exposed fasteners.
The hollow multi-cavity structure of the 160x20mm profile is optimized to maintain structural strength while reducing dead weight. Packed in heavy-duty export cartons with protective corner guards, the panels achieve high-density stacking inside 40'HQ containers. A single 40'HQ container accommodates approximately 2,300 to 2,600 square meters of wall covering, substantially reducing unit ocean freight costs for overseas B2B importers.
