WPC -Wall Panel

A: A WPC (Wood Plastic Composite) wall panel is an indoor and outdoor wall cladding product manufactured from a composite material that blends wood fiber or bamboo fiber (typically 50–60%) with thermoplastic polymer (PVC, PE, or PP, 30–40%) and functional additives (coupling agents, UV stabilizers, colorants, foaming agents, 5–10%). The mixture is extruded or molded into profiled planks with a tongue-and-groove interlocking edge system. WPC wall panels combine the natural appearance and workability of wood with the waterproof, rot-proof, and low-maintenance properties of plastic - they do not require painting, sealing, or staining, and they resist moisture, insects, and UV degradation far better than natural wood. WPC wall panels are widely used for exterior façades, interior accent walls, ceiling cladding, balcony and fence screening, and garden wall decoration in residential and light commercial applications.

A: The typical MOQ is 200–500 square meters for standard profiles and colors. For custom profile shapes or non-standard colors, MOQ is typically 500–1,000 m² due to extrusion die setup and material changeover requirements. Sample planks (300–600mm length) are available for quality and color evaluation. Please provide your preferred profile width, thickness, color, and application (interior/exterior) for a quotation.

A: Common applications:
· Exterior wall cladding (façade): modern rainscreen cladding for residential and low-rise commercial buildings - weather-resistant, UV-stable, wood-look without maintenance
· Interior accent/feature walls: TV background walls, bedroom headboard walls, living room feature walls - warm wood aesthetic, quick click-together installation
· Balcony and terrace wall cladding: waterproof, weather-resistant walls and ceilings for outdoor living spaces
· Ceiling cladding: porch ceilings, balcony soffits, corridor ceilings - lightweight, easy to install overhead
· Fence and privacy screening: garden fence panels, balcony privacy screens, boundary screening - no rotting, no painting
· Soffit and eave lining: underside of roof overhangs - ventilated profiles available for attic ventilation
· Garden and landscape walls: retaining wall facings, raised planter box cladding, outdoor kitchen surrounds
· Commercial interiors: shopfitting wall panels, restaurant wall cladding, office partition screens
· Bathroom wall cladding: 100% waterproof wall panels - alternative to tiles with faster installation
· Basement wall cladding: moisture-resistant wall covering for below-grade spaces where traditional wood or drywall fails

A: ① Real wood appearance without the maintenance: WPC panels are embossed with realistic wood grain textures, including deep-embossed (3D) grain that looks and feels like real timber. Unlike wood, they never require painting, staining, sealing, or oiling - simply wash with water occasionally. The color is integrated through the material thickness (not a surface coating that peels).
② 100% waterproof and rot-proof: WPC does not absorb water. It will not rot, warp, swell, or support mold growth - even in bathrooms, basements, exterior façades, and tropical climates. Natural wood in these applications degrades within 2–5 years.
③ Termite and insect-proof: the plastic component of WPC makes it inedible to termites, wood borers, and other insects - a decisive advantage in termite-prone regions where natural wood is unviable.
④ UV and weather-resistant (co-extruded): capped WPC with ASA or acrylic co-extruded surface layer provides excellent UV resistance and color retention for exterior applications. Capped WPC retains its color for 10–15 years outdoors vs. 2–3 years for painted wood.
⑤ Fire-retardant options: WPC can be formulated with fire retardants. Standard WPC achieves Class B2; fire-retardant WPC achieves Class B1 (GB 8624). PVC-based WPC has inherent flame-retardant properties due to chlorine content.
⑥ Easy click-together installation: tongue-and-groove or click-lock joints make installation fast and simple - no special skills required. Panels are fixed to the substructure with hidden clips or screws through the tongue. A DIY-capable installation saves labor costs.
⑦ Low thermal conductivity - feels warm: WPC's thermal conductivity (~0.15–0.25 W/m·K) is much lower than aluminum or ceramic tiles. The panel feels warm and comfortable to the touch - important for interior walls.
⑧ Acoustic and thermal insulation: the hollow chamber profile creates an air gap between the wall surface and the substrate, providing a degree of sound and thermal insulation. Foamed WPC has even better insulation properties.
⑨ Cost-effective over the life cycle: while WPC may have a higher upfront cost than painted wood or PVC panels, the elimination of maintenance (no painting, no replacement due to rot/insects) makes the total lifetime cost significantly lower. WPC panels have a service life of 15–25 years.
⑩ Eco-friendly use of recycled materials: WPC can incorporate recycled wood fiber (sawdust, rice husk, bamboo waste) and recycled plastic (post-industrial or post-consumer). This diverts waste from landfill and reduces demand for virgin timber.

A: Surface textures:
· Light brushed wood grain: subtle texture - suitable for modern, Scandinavian, and minimalist interiors
· Deep embossed (3D) wood grain: pronounced, tactile grain texture - highly realistic, the texture aligns with the printed grain pattern for authenticity
· Sanded / smooth: flat matte surface, no grain texture - for solid color panels and contemporary interiors
· Wire-brushed: linear brushed texture - rustic, weathered wood aesthetic
· Hand-scraped: irregular, distressed surface - vintage and farmhouse styles
· Stone / concrete texture: for non-wood-look panels - modern industrial aesthetic
Wood grain colors:
· Warm tones: teak, cedar, golden oak, cherry, mahogany, redwood
· Neutral/natural: natural oak, ash, birch, maple, beech
· Dark tones: walnut, wenge, dark oak, espresso, charcoal
· Grey and weathered: driftwood, silver-grey, weathered grey, antique oak, rustic barnwood
· Painted-look solid colors: white, cream, light grey, dark grey, black, beige, sage green, navy blue
Profile shapes:
· Flat plank (square edge): classic, simple - most economical
· V-groove: a V-shaped groove between planks creates a shadow line - emphasizes the plank pattern
· Shiplap (rebated overlap): overlapping edge creates a weatherproof joint - traditional exterior cladding profile
· Beveled edge: angled edge creates a subtle shadow line - refined architectural appearance
· Custom profile: cove, scalloped, fluted, slatted - for decorative effects
Installation orientation:
· Horizontal: the most common - emphasizes room width
· Vertical: adds perceived height to the room
· Diagonal / herringbone: decorative - for feature walls
· Mixed: alternating orientations in different wall zones

A: Standard WPC (without fire retardants) is classified as Class B2 (combustible) under GB 8624. For applications requiring fire resistance:
· PVC-based WPC: inherently more flame-retardant than PE or PP-based WPC due to PVC's chlorine content (self-extinguishing). Typically achieves Class B1 with additional fire retardants.
· Fire-retardant WPC: the formulation includes ATH (aluminum trihydrate), magnesium hydroxide, or intumescent additives - achieves Class B1 (flame-retardant) under GB 8624 and EN 13501-1 Class B or C. Used in public buildings, commercial interiors, and exterior façades.
· Co-extruded fire-retardant cap layer concentrates fire retardants at the exposed surface for maximum effectiveness.
Fire performance varies significantly by manufacturer and formulation. Always request fire test reports for the specific product being specified. Fire-retardant WPC is mandatory for exterior façades on buildings above certain heights (varies by local building code) and for interior wall linings in escape routes and public assembly areas.

A: · Standard profiles and colors in stock: 5–10 working days
· Custom colors (within standard profile range): 10–20 working days (color matching and trial extrusion)
· Custom profile shape (new extrusion die): 20–35 working days (die design and fabrication 1–2 weeks + trial and adjustment 1–2 weeks + production)
· Large project orders (5,000+ m²): phased delivery scheduled case-by-case
Extrusion is a continuous high-speed process - production speed 2–8 m/min depending on profile complexity and cooling requirements. Stock color availability: most manufacturers maintain stock of 10–20 popular colors (teak, walnut, oak, grey, white, etc.). Custom colors require a minimum extrusion run.

A: Packaging: WPC panels are stacked in bundles of 5–20 planks (depending on size and weight), wrapped in PE film or shrink-wrap. Corner protectors are applied at both ends. Bundles are packed in heavy-duty corrugated cartons or strapped to pallets. Each bundle is labeled with product code, color, and quantity.
Shipping:
· Domestic: dedicated logistics, door-to-door
· International: FCL sea freight. FOB/CIF terms.
Container capacity: a 40HQ container holds approximately 1,500–2,500 m² of WPC wall panels (depending on profile thickness and hollow/solid ratio).
Handling and storage: store flat on a level surface in a dry, ventilated area. Avoid direct sunlight on uncapped WPC for extended periods (may cause slight color change). Do not stack heavy items on top. Keep packaging intact until installation.

A: Installation - designed for fast, simple, dry installation:
① Substructure preparation: for interior walls, WPC panels can be installed directly over drywall, plaster, or concrete with adhesive OR on timber/aluminum furring batten strips. For exterior façades, a ventilated rainscreen substructure (vertical timber battens or aluminum profiles at 400–600mm centers over a weather-resistant barrier) is required.
② Orientation and layout: decide panel direction (horizontal/vertical) and mark level reference lines with a laser level. For horizontal installation, start from the bottom; for vertical, start from a corner.
③ Trims and accessories: install starting trim (base channel), corner trims (internal and external), end caps, and J-trim profiles before panel installation. The trims provide a clean finish and hold the first and last panels.
④ First panel: insert the first panel into the starting trim. Ensure it is perfectly level/plumb - this panel determines the alignment of the entire wall.
⑤ Fixing: screw through the tongue (hidden fixing) into the batten or substrate using stainless steel or coated screws - the next panel's groove covers the screw head. For adhesive installation, apply MS polymer construction adhesive in vertical beads on the panel back and press firmly to the wall.
⑥ Subsequent panels: engage the groove over the tongue of the installed panel. The joint should close fully. Secure through the tongue. Periodically check level/plumb.
⑦ Cutting: cut to length with a standard miter saw using a fine-tooth carbide blade (60–80 teeth). For cutouts around outlets and switches, use a jigsaw or oscillating multi-tool. Cut face-up for the cleanest visible edge.
⑧ Last panel: measure and rip-cut (lengthwise) to fit the remaining space. The cut edge is hidden inside the finishing trim.
⑨ Finishing trims: install the final trim profiles after all panels are in place - they cover exposed edges and provide a professional finished look.
⑩ Expansion allowance: WPC expands and contracts with temperature changes. Leave 5–8mm expansion gap at panel ends (hidden inside trim profiles). For long continuous runs (>6m), use an expansion joint trim.
⑪ Cleaning: remove any dust or debris with a microfiber cloth. For exterior installations, a low-pressure water wash removes accumulated dirt. No chemical cleaners needed.
