WPC Solid Embossed Slat 70 x 10 mm (0.936 kg/m) is a strip made for working, not a board made for covering. Its section is a solid 7 cm2 and its density works out at 1.337 g/cm3 — the highest figure in the range for any solid section (solid decking is 1.226, dense co-extrusion 1.261-1.280) — which tells you there is almost nothing in it but material. The rest is standard WPC: it takes in no water, so it will not rot, split, host insects or grow mould; no paint and no wax, ever; a UV-stabilised formula keeps the colour from bleaching year after year. For a wall, a joint or a corner that needs the line of timber without the repainting every few years, this 70 x 10 solid embossed strip is what it is for.
