Compared to the two-layer parquet, one more – the third layer – has been added to the three-layer parquet, which has an additional stabilizing function. Namely, in order for the wooden floor boards in larger formats (width from 150 mm upwards) to be sufficiently strong and stable, it is preferable that they be made of 3 layers, i.e. produced in the form of three-layer parquet. Double-layer parquet is usually produced in smaller formats in which the two-layer construction is sufficiently stable.
