Panels are cut from one slab so the grain continues across the wall rather than restarting at every joint. Full-height panels come from the 2400 × 1600 mm slab; anything taller is book-matched from two. Thickness is 18 mm or 20 mm, and 12 mm is made to order for a substrate that cannot take more. Flatness tolerance ±0.3 mm, diagonal ±1 mm.
