A wall panel cut from one slab, grain continuous across the wall. On the grey board the straight figure is what stops it reading as a flat grey plane: the lines are quiet, but they are there, and they catch the light as the sun moves across the wall.
Full-height panels come from the 2400 × 1600 mm slab; a wider wall is book-matched from two.
Thickness is 18 mm or 20 mm, with 12 mm to order. Flatness tolerance ±0.3 mm, diagonal ±1 mm.
