Wood grade : Oak
The wood grade, for a parquet floor, refers to the level of selection of the strips before they are manufactured.
The wood used to make parquet strips naturally contains characteristics (knots, sapwood, colour variations). Wood strips can therefore be sorted according to the characteristics present in the wood. The choice of wood is a purely aesthetic sorting criterion and has no impact on the quality of the wood or the lifespan of the floor. Wood is a natural material. You will never find two identical strips, as each parquet strip will have its own unique characteristics.
Here are the different types grades of oak offered by Design Parquet:
