What is the difference between three layer solid wood and multi layer solid wood in terms of texture

No matter in terms of environmental protection, applicable geothermal energy, stability and durability, three-layer solid wood is incomparable with multi-layer solid wood

1.Environmental protection: The three-layer solid wood structure is simple, the core board is made of wood strips, a large amount of glue is used, and in order to enhance the adhesion between the veneers, a sufficient amount of glue must be applied to ensure that it is not layered in the geothermal situation, so environmental protection is difficult to control.

In fact, to distinguish whether a floor is environmentally friendly, it depends on the adult test results of the finished product.

2.Stability, suitable for geothermal heat: the tensile force of the three-layer solid wood cannot be balanced because it is difficult to balance the weight of the surface plate and the back board, and the wood fiber of the solid wood core of the core board is transverse, while the wood fiber of the surface board and the back plate is longitudinal, that is to say, the three layers only have the approximate distribution direction of two wood fibers, and it is difficult to achieve the tic-tac-toe structure, and there is no stability.

The multi-layer solid wood is criss-crossed by more than nine layers of veneer, layer by layer of hot pressing, with less glue, and well-shaped distribution, the internal prestress is set well, which enhances the stability of the whole board and is more suitable for geothermal environment.

3.Difficult to use: Single-layer solid wood cannot be used for geothermal because once the moisture content of single-layer solid wood is reduced, there will be cracking, bending and deformation of the surface layer.

Similarly, the three-layer solid wood surface plate is thicker, and the core board is made of wood strips, in order to reserve the so-called expansion joint, can not really be sealed, the air inside the board body can be freely circulated, so the moisture resistance effect is very poor, the same way, the moisture content is difficult to control, easy to appear surface cracking, bending and arching phenomenon.

In fact, the three-layer solid wood on the market is just emerging, and the practicality has not yet been tested by the industry market. Low cost, high return is the reason why many businesses are currently working hard to push three-layer solid wood, hereby remind the majority of owners that in terms of home improvement durable goods, it is best to choose products that have been tested and matured by the market. Multi-layer solid wood has been tested by the mainland market for more than 10 years, and its stability, technical parameters and environmental protection are recognized.
