WOOD QUALITY - FEEL WOOD GRADES
The grading process is carried out by our experienced staff following strict rules. Different wood species have various grades due to their diverse grain patterns and presence of knots. Wood without knots and minimal color variations is usually rare and, therefore, more expensive. However, this does not necessarily mean higher quality for the planks or parquet. Choosing the grade is a matter of personal preference and expands design possibilities.
The various grades offer different performance characteristics. The durability of a wooden floor depends more on its structure than the hardness of the wood. Naturally grown floors with pronounced structures are more resilient compared to lighter and knot-free ones. This is because wear and tear marks are less noticeable, and ast-rich and naturally grown grades tend to have higher hardness.
However, when selecting the grade, the environment should take precedence. The chosen grade, as well as the wood species, should harmonize with the room and existing furnishings. The grade determines whether the wooden floor discreetly complements the room, highlighting the furnishings, or becomes a significant influence on the overall space.
We recommend evaluating hand samples or sample panels next to your furnishings under appropriate lighting conditions to choose the grade. The impact of light on different woods can significantly affect the wood's appearance.
