WPC Wide Wavy Wall Cladding 219 x 26 mm (2.83 kg/m) is the widest board in the range and the lightest wavy board per square metre. At 219 mm it covers a square metre with only 4.57 m of board - 3.7% less than a 211 mm board, 23% less than 168 mm and more than a third less than a standard 140 mm. Cleaning follows the same logic as any wavy board: the face is a series of slopes that will not hold water, so rain runs straight off and carries the dust with it, leaving no ponding marks; dust settles slowly in the recesses and a hose now and then is the normal upkeep - more than a flat board needs, far less than timber slats demand. Outdoor performance is unchanged: it takes in no water, so it will not rot, split, host insects or grow mould; UV-stabilised so the colour will not bleach; no paint and no wax, ever. For a large wall that needs the least board, the least weight per square metre and a sculpted face, the 219 mm is the one built for it. 219 x 26 mm wavy WPC wall cladding, 2.83 kg/m - the widest face in the range at 4.57 m of board per square metre, and the lightest wavy board at about 12.9 kg per square metre.
