Overview
The SONSILL Wood Grain Co-extrusion WPC Wall Cladding is a premium four-sided capped wood-plastic composite exterior facade board engineered for holiday villas, boutique cafés, guesthouses, and residential and commercial building facades where a realistic natural timber grain aesthetic and long-term outdoor performance are the primary specification requirements. The co-extrusion manufacturing process bonds a high-density UV-stable polymer cap to all four sides of the WPC core, replicating the depth and texture of natural timber grain while delivering superior resistance to UV degradation, moisture ingress, surface staining, and colour fade over a 25-year residential service life. At 156mm wide and 21mm thick, this narrow-board profile creates an authentic horizontal or vertical timber cladding facade that pairs naturally with stone, render, and glass architectural elements. Designed for architects, facade contractors, and wholesale distributors specifying premium low-maintenance exterior timber-alternative cladding for residential and hospitality projects.

Installation
SONSILL Wood Grain Co-extrusion WPC Cladding boards install horizontally or vertically onto a prepared aluminium or galvanised steel subframe using a hidden clip fixing system or face-fix stainless steel 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. Finish all exposed board ends with compatible SONSILL WPC end caps or aluminium trim sections. Contact SONSILL technical support for facade engineering specifications, subframe design, and large-scale residential or hospitality project installation documentation.
