148mm UV Shield WPC Wall Cladding Panel Fade Resistant
Product Summary
Capped with a 360-degree high-density polymer shell, this WPC cladding features industry-leading UV inhibitors that lock in color pigments. It prevents the outdoor facade from whitening or becoming patchy under intense solar radiation, ensuring a rich, consistent, wood-like aesthetic for commercial and residential developments over decades.
Tested under accelerated weathering, the co-extruded cap layer resists UV degradation, keeping the facade looking like new without whitening.
Unlike basic composites, the protective layer wraps around the entire board including the grooves, blocking sunlight and moisture from all angles.
Utilizes advanced multi-tonal color blending technology to replicate natural timber, ensuring the matte finish looks realistic, not plasticky.

Installing the Joists (Battens):
If the cladding panels are installed horizontally, the joists must be installed vertically (and vice versa). Fix the joists to the wall using expansion screws. Keep the center-to-center distance between the joists at 30cm - 35cm (if the spacing is too wide, the wall will sag or flex).
Fixing the First Panel:
Start from the bottom or the side. Use a starter clip (or screws) to secure the edge of the first panel to the joists. Make sure to double-check that this first piece is perfectly level or vertical.
Interlocking & Securing:
Insert the tongue (male profile) of the next panel into the groove (female profile) of the previous one. Snap the dedicated fixing clip onto the exposed joint where the panel meets the joist, and tighten the screw. Repeat this process, stacking them like building blocks.
Finishing & Trimming:
Cut the final panel to fit the remaining space. Cover and seal all perimeter edges and corners using matching L-shape corner trims (secured with structural adhesive or a brad nailer).
A1: It undergoes a very slight, natural gloss reduction and color stabilization within the first 6 months of outdoor exposure. After this initial stabilization period, the color locks in and remains visually unchanged for the next 15+ years.
A2: Our WPC products are rigorously tested under international standards like ISO 4892-2 (Xenon-arc exposure). Under these controlled laboratory conditions, the material achieves a Delta E color change rating of less than 4.0 over simulated decades.
A3: Never. The protective polymer cap and the WPC core are molecularly bonded together at over 200 °C during the hot co-extrusion process. They form a single, inseparable unit that will not delaminate, bubble, or peel.
