Most floors become unsightly with age, wooden floors become more beautiful with age.
Every trace you leave on it tells a story.
That’s why people say, “Wood lives.”
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. These natural characteristics cannot be completely excluded, but may not exceed 5% of the delivered quantity. For solid wood flooring, slight dimensional tolerances (+/- 0.25 mm) are commercially available and unavoidable.
Below we give you an overview of the sorting characteristics of the common wood species oak.
The definition of sorting regulations is based on 4 quality criteria:
Sporadic smaller, healthy knots, natural wood colour, harmonious grain, growth-related differences in colour
Healthy, compactly grown, as well as medium and filled knots, in principle free of sapwood
filled knots, compactly grown knots, vivid structure, smaller cracks, other wood typical characteristics
open knots as will and filled surface cracks, cracks at the head and long sides unlimited sapwood, technically proper
