Multilayer flooring is a type of floor or pavement made up of several layers of glued wood. It is an option of quality, durability and enormous decorative presence due to the use of noble woods.
How is it different from other types of laminate flooring or laminate flooring? There are two big differences. The first is that all the layers that make up the platform are made of wood, or at least derivatives of it. And the second difference, derived from the first, is that the outer layer is a natural wood veneer and not a printed design, with all the advantages and disadvantages that this implies.
Composition Of Multilayer Floor
As can be seen from its name, multilayer flooring is made up of different layers. These are glued and pressed, obtaining a product of great stability and resistance. Typically, the thickness of the sandwich is between 12 mm and 16 mm.
The Layers Are As Follows:
Back side . This layer, normally formed by a veneer of coniferous wood such as pine and about 2 mm thick, has the function of stabilizing the slat.
Intermediate layer . It is the core of our multilayer flooring. It has an approximate thickness of 10-6 mm and is the layer with the mechanization of the anchoring or click system.
It can be composed of different materials or derivatives of wood:
Plywood. It is a very stable and resistant solution . Woods such as poplar, birch or eucalyptus, and adhesives or phenolic glues are used, which improves resistance to humidity.
MDF – HDF. Medium or high density fibreboard. Higher density is always preferable. It offers good performance, significantly reducing the price compared to plywood.
Solid Wood Slats. Also called blind. Something less common today, since it is not a uniform surface, it can generate waves in the noble layer after slashing.
Noble or Wear Cloak . It is the natural wood veneer that will give the appearance to our floor. Hardwood species specially selected for their decorative qualities are used. Some of these can be: walnut, oak, merbau, jatoba, mahogany, iroko …
The type of veneer or species used for this layer and its thickness are one of the determining factors in the price of multilayer parquet. The more exclusive the wood and the greater the thickness, the higher the price.
The thickness of this layer is also important from the point of view of the useful life and durability of the deck. It will determine the number of times our floor can be stabbed (sanded and varnished). The most economical ranges have such a thin layer that they do not even allow a slash, around 1 mm. The most common thicknesses are between 3.2 and 4 mm.
The design can be monolame, that is, the sheet covers the entire plank, or mosaic to achieve smaller table designs.
Surface Treatment . Multilayer flooring is not always marketed with an applied treatment, many times it is done raw, although it will finally have to be applied to protect the wood.
The two most common treatments are oil and varnish. You will find more details in the finishes section.
