1. Parquet typically uses layers of foam sheets first, to avoid uneven floor surfaces and squeaking sounds.
2. For ease of pairs, laminate parquet is designed with an interlocking system between the tongue and the niche. On one chip, the left side is the tongue and the right side is the niche; the upper side of the tongue and the lower side of the niche. How to install it is to insert the tongue of the one chip into another niche. This is different from the installation of ceramics that each piece should be glued to the floor under it. Here the adhesive is also needed, but only to stick between one piece with another (glue applied to tongue and niche).
In this way, the installation of laminate parquet wood flooring becomes easier, such as to install a puzzle. And in addition, because it does not need to be glued to the floor below, this floor covering can be applied on the floor that has been covered ceramic or other materials.
