And wood already has character when laying. This means that despite strict quality controls on individual planks growth-related peculiarities, such as drying hairline cracks, slight colour differences, etc. may occur.

For solid wood flooring, slight dimensional tolerances (+/- 0.25 mm) are commercially available and unavoidable.
