WPC Solid Straight-Grain Slat 70 x 10 mm (1 kg/m) is a strip made to be laid in runs — its grain runs as parallel straight lines along the length, not as scattered timber figure. That direction is exactly what divides it from the embossed version: an embossed strip is for looking at up close, where the relief and the light and shade read as real timber; but when you set dozens of strips side by side into a slat wall, a screen or a ceiling, every embossed strip carries its figure in a different direction, so the run reads as scattered — and the joints are where the change of direction shows worst.  70 x 10 mm solid straight-grain WPC slat, 1 kg/m — the grain runs parallel along the length, so dozens of strips read as one continuous face of straight-grained timber; density 1.429, the densest solid strip we make.
