What are the top ten brands of solid wood multi layer flooring?

It's not that the more layers, the better, these are two different plates.

Thickness difference: the surface layer of the three-layer solid wood composite is at least 3 millimeters thick, the multi-layer is basically millimeter thick, and the surface layer of the three-layer solid wood composite is at least 50% thicker than the multi-layer solid wood composite surface layer. It can be up to 5 times thicker than the difference.

Process differences: the difference in technology is more professional, the surface layer of three-layer parquet is sawn wood because it is at least 3 thick, while the surface layer of multi-layer parquet is basically rotary cut wood.

About the core material: The core material of the three-layer solid wood composite is cut out of the whole board saw, on the one hand, there are requirements for the age of the tree, and at the same time, the veneer needs to be treated for health.

Multi-layer solid wood composite is glued with mixed boards, and there is no requirement for wood, and the cost is very different from this point;

At the same time, there are expansion joints between the core materials of the three layers, and the processing technology is more complicated, but it ensures that the core materials will not produce great deformation from the structure, even if they are used in the environment of floor heating, there is no problem, and the stability will be better.

About the lock: the three-layer solid wood composite can be made into a lock structure, and the multi-layer can only be made into a flat buckle structure. In the underfloor heating environment, the lock is particularly important, first, the lock is installed without sizing, which is more healthy and environmentally friendly.

About environmental friendliness:

The biggest harm to the human body is formaldehyde, the source of formaldehyde is mainly glue, so the glue content of the floor is a key issue. Layer parquet and multi-layer parquet from the structural comparison, three layers we all know that only 3 layers are compounded together, multi-layer is generally 11 layers or 9 layers compounded together. Here's a simple and easy-to-understand example:

If the three layers are laminated together, it is necessary to apply glue on both sides. If 11 layers are compounded together, at least 10 sides of the sizing are required. From this ratio, it is not difficult to see that the three-layer parquet has less glue content and is more environmentally friendly.
