Overview
The SONSILL 219mm Co-extrusion WPC Wall Cladding is a premium four-sided capped wood-plastic composite facade panel engineered for outdoor building cladding, villa exterior walls, commercial building facades, and garden boundary wall applications. The co-extrusion manufacturing process bonds a high-density protective polymer cap to all four sides of the WPC core, delivering superior resistance to UV degradation, moisture ingress, surface staining, and colour fade compared to standard single-cap or uncapped WPC profiles. At 219mm wide and 26mm thick, each 2900mm-length board provides substantial facade coverage with a natural timber-grain aesthetic that requires no painting, staining, or sealing over its service life. With a 25-year residential and 15-year commercial service life rating, this panel is designed for architects, facade contractors, and wholesale distributors specifying long-term, low-maintenance exterior cladding solutions for residential and commercial building projects.

Installation
SONSILL 219mm Co-extrusion WPC Wall Cladding boards install horizontally or vertically onto a prepared aluminium or galvanised steel subframe using a hidden clip fixing system or face-fix screws. Erect the subframe at 400–600mm centres, ensuring all members are level, plumb, and structurally fixed to the building substrate. For hidden clip installation, fix the first board at the base of the wall and engage the clip into the board groove before fixing the clip to the subframe. Continue installing boards upward, engaging each board into the clip of the previous board. Maintain a minimum 10mm expansion gap at all board ends and perimeter junctions to accommodate thermal movement. For face-fix applications, pre-drill pilot holes to prevent board splitting. Finish all exposed board ends with compatible SONSILL WPC end caps or aluminium trim sections.
