PROCESS IN WOOD: MANY STEPS FOR AN UNIQUE PRODUCT
To become a floor that can be installed in our homes, the timber must pass several stages of processing, ensuring regulatory compliance and best final yield.
In particular, as we described in the previous article, after the cutting there is the curing and seasoning of the logs.
In this case, the logs are cut in the wood from the tree farms, divided into tables and then in elements from sawmills that are always in the state of belonging.
The Oak mostly comes from the forests of Slavonia and sawmills can be found in Croatia and Bosnia Herzegovina.

During this phase of seasoning, which may last a few months, the wood goes down from a moisture level of 80/90% (at the time of cutting) to about 25%.
This reduction allows us to insert elements boards in dryers, large furnaces that emit hot air loop controlled to bring the wood moisture content to the desired level.
Drying takes place mostly through two distinct techniques: in a furnace or under vacuum-seal. In the first case the elements are placed in environments with streams of hot, dry air, while in the second mode the timber is placed in environments that recreate conditions of thermal vacuum, which allows the evaporation of water at low temperatures.
The drying process brings moisture of the material to a value of about 8%, that is when it can be used in the composition of the wooden floors.

At this point the wooden boards can be divided into lamellae with a thickness of approximately 4.5 mm, and subsequently calibrated to be glued together to form multilayer flooring.
The main formats marketed in Italy can be divided between solid wood floors, in regular and constant profile thickness (the wooden element is composed of a single block) and multilayer wood floors, where the element is constituted by a core formed by more layers glued together.
To get to compose our prefinished plankings, elements of slats are glued with vinyl glue, traditionally support of phenolic birch plywood, which gives more quality to the final product.
In particular, the lower support has the purpose to keep the floor deformable, counteracting the natural tendency to displacement and ensuring resistance properties and high robustness.
In the case in which the wood present irregularities or nodes we proceed with the plastering of the imperfections (if necessary), and with the final calibration of the boards, now already become compounds multilayers.
It therefore provided the material processing stage with the woodworking, where they recreated the joints that allow the laying of the parquet. In professional jargon, these joints are commonly called "male" (the protruding part) and "female" (the concaved and hollow part).

Now our floor is ready to be manufactured and finished to the tastes and needs of the customer, choosing from a wide range of finishes and processing.
It is important to note that for the choice of the floor plays a vital role not only the taste, but also the type of local, environmental conditions, functionality and texture of wood.
In fact, depending on the variables in play, it is biased to a different type of essence and realization.
We will deal this aspect in the next article, where in addition to analyzing the different types and characters of wood flooring, we will see which wood is functional to the different types of environment.
 
So don’t miss the next appointment!
