WPC Wall Cladding 156 x 21 mm (1.86 kg/m) is a board that takes lightness as far as it will go. Cladding works in a completely different direction to decking: it hangs on a wall, and weight brings it nothing but trouble. So this board is made as a thin-wall hollow section - 1.86 kg per meter, less than half the 4.02 kg/m that the same size would weigh in solid WPC, a saving of 54%. And afterwards there is no heavy board dragging on its fixings, sagging or working loose. At 156 mm the face is an efficient covering width - wider than the usual 140 mm and 150 mm, so you use fewer boards and fewer joints and the wall reads as one continuous surface. The 21 mm thickness keeps each board stiff and the joints flat, with no bowing or sagging between fixings.  156 x 21 mm WPC wall cladding, 1.86 kg/m - half the weight of solid board, goes straight over an old wall, one person can fix it, and it never needs painting.
