With the increasing demand for quality of life, the choice of floor materials is becoming more and more diverse. Among the many floor materials, solid wood flooring has always been favored. The new three-layer solid wood floor is a flooring material that has attracted much attention in recent years. From the aspects of substrate, surface layer, environmental protection, stability, price, etc. to provide friends who want to know about home improvement flooring with the idea of buying composite flooring.

Substrate: Three layers is better than multiple layers

① The base material of multi-layer solid wood flooring is mostly eucalyptus core three plywood or five plywood, that is, plywood. In addition to some imported or large brands, many small multi-layer solid wood manufacturers will not go to their own substrate, just buy ready-made three-layer plywood, and after painting directly put into the market for sale, so there is no quality guarantee for this type of product.

The three layers of solid wood is not simply the three pieces of wood superimposed together, its substrate core board is composed of countless small wood strips adjacent combination, and each wood strip also leaves an appropriate gap, so that the wood can fully expand and contract, without affecting the overall deformation. There are no finished products on the market of this substrate, which can only be completed by the manufacturer itself, so the strength and technology of the manufacturer are tested, and the product can be traced to the source is more guaranteed.

Surface layer: three layers are better than multiple layers

For composite flooring, the role and status of the floor surface layer is very high, which often determines the service life of the product. Generally, high-quality tree species with high wear resistance are selected to protect and wear well.

Environmental protection: three layers are better than multiple layers

Environmental protection is one of the real issues to be concerned about when buying a floor, no matter what kind of composite floor, the two adjacent layers must be connected through adhesive. Therefore, it can be intuitively concluded that the less the number of layers, the smaller the amount of glue used, and some high-quality hardwoods have small glue absorption, which is also more conducive to creating an environmental environment. And the domestic three-layer solid wood is more used for export, foreign requirements for environmental protection are stricter than domestic, so it also ensures the environmental performance of three-layer solid wood.

Stability: Multiple layers are better than three

Friends who have understood should know that wood has internal stress, the existence of this force is the root cause of wood cracking, so the manufacturer has a step in the production process called "eliminate internal stress."

Three layers of solid wood is sawing process, it ensures the integrity of the wood, so that it will not lose "activity", three layers of solid wood flooring is also there with the change of humidity shrinkage and expansion characteristics. However, the structure of the three layers of horizontal and vertical interlocking each other, compared with pure solid wood flooring, its deformation probability is greatly reduced, but it is less stable than the multi-layer.

Price: Multi-tier is better than three-tier

This point friends can be intuitively seen in the market, due to the production process, material selection and utilization rate and many other factors, the price of multiple layers is often more affordable than three layers.

The above is to compare the difference between three layers and multiple layers from five aspects, and I believe that friends who need this can also have a certain judgment. In particular, friends who plan to install floor heating, whether it is a solid wood floor or a composite floor, must choose a professional degree, a good reputation, a trusted brand, and consumption can be more guaranteed.

Multi-layer solid wood due to the need for thinner wood, generally using the rotary cutting process, after the rotary cutting will destroy the structure of the wood itself, while the internal stress of the wood is also destroyed, so that the wood becomes a "dead thing" after reducing the possibility of deformation.
