Today I want to start telling you a short story .
When I was a child I used to play in the football team of my country.
I was one of the most timid children and immediately, because of my nature, I was relegated to the role of defender.
What does it mean to be a defender?
Being a defender of a Football Team means you have to stay there, near the penalty area of your team and never cross the halfway line, being careful to stop the opponents forwards.
So do the dirty work, grab and kick and then the other players take the credit and honor of the victory.
In fact, most of the other children could go on the attack and score some goals, or at least try to do it.
There is no greater satisfaction for a child who plays football!
So, sometimes, I also felt useless and marginalized within the team.
Actually I didn’t understand that my role was crucial because playing well could prevent the opposing team from scoring.
So my companions would have more chance to make goals.
As a result the team could win.
It was a fundamental part of the bearing structure of the team!
Without me and the other defenders, it would have been very difficult to win a few games.
Well, today I want to talk to you about those materials, often marginalized and leered by those who, stupidly, judges them badly because they “never score goals.”
They don’t appear in the final result, but they are ESSENTIAL to achieve it!
Let’s find out together!
The Artificial Woods are mainly used to made internal structures, not visible to those who will use the object, because of their appearance often coarse.
Thanks to their low prices and excellent technical quality are also often used to make panels and furniture for workshops and laboratories , where it is inconvenient (and also a waste) to use more expensive and fine materials!
For the same reason they are also used to create templates, forms, and other useful laboratory pieces .

WHAT ARE THE ARTIFICIAL WOODS?
The artificial woods are materials that are obtained from the scraps of wood.
They were introduced in the 19th century and have totally revolutionized the way of doing carpentry.
Currently around 80% of existing products is accomplished by assembling artificial woods with natural wood.
So it is crucial to know them because they help us to build almost anything.
Let’s find out what are these Artificial Woods .
TYPES OF ARTIFICIAL WOODS
Here you can find the types of Artificial Woods covered in this article:
- Marine plywood
- LDF / MDF / HDF
- Layer wood
- Honeycomb wood

The Plywood is also called Multilayer Wood precisely because made with thin layers of overlapped wood in which the fibers are placed at 90 degrees relative to one another .
It is also called Compensate Wood because it is thanks to this composition, which is able to compensate deformations , such as twisting, stretching and shrinkage of the material.
The plywood is well recognizable because the layers are very obvious looking at the section .
Given the cross-positioning , the layers appear in different colors.
In reality it is the same material, but seen with the fiber in the longitudinal or transverse section.

There is then also the marine plywood which serves mainly to realize the outdoor facilities in which it needs an high resistance to moisture .
It’s an high quality multilayer in which the veneers are glued with synthetic resins,urea formaldehyde, resorcinol or phenolic based.
It is manufactured using selected sheets of a limited variety of species similar to mahogany.
The sheets of marine plywood are very compact.
They don’t have holes and resist also underwater.
They do not fret and do not change even if exposed to snow or sun!
Of course it can also be used for indoor furniture because it is very durable.
It has the downside of being very expensive.
LDF, MDF and HDF

No, it’s not my tax code…
It’s the tax code, or rather the letters that indicate certain types of Artificial Wood.
LDF : Low Density Fibreboard
MDF : Medium Density Fibreboard
HDF : High Density Fibreboard
The density changes, but in practice are obtained from the union of fine wood fiber , compacted and blended by high strength glue .
The wood fiber may be of various types, but usually they prefer the wood of coniferous trees .
This wood is first stripped of bark and then crushed and ground to become fiber with the help of water and chemicals.
The procedure can be done either dry or by wet milling.
The most widely used of this 3 types in carpentry is probably the MDF .
The main quality of this Artificial Wood is the compactness that makes it easy to work, especially in the case of shaping and milling.
It has the defect of being quite heavy, it doen’t have natural wood veins, but that is why it lends to be painted and lacquered homogeneous.

As the name indicates the same Chipboard is formed from wood “chips” obtained from the woodwork kneaded with resins and high strength glues.
Unfortunately, very often, due to the high demand for this material (very inexpensive), a barbarian deforestation is carried out exclusively in order to obtain chips aimed at the realization of the chipboard .
It can be found in various thicknesses and is used in the construction of furniture.
The aesthetic is very bad if not bordered and veneered with fine wood or covered in some way.
In addition, because of its very porous composition , it is unusable for outdoor furniture and must be combined with special screws and glue to prevent it from flaking, or worse, splitting.
The OSB ( Oriented Strand Board ) is an Artificial Wood consists of several superimposed layers formed from wood chips .
These chips are mainly of a long and narrow shape (strand) and are held together by a glue.
The wood chips are positioned so as to improve the technical properties (strength and bending resistance) of the panel.
There are 4 types ( OSB / 1, OSB / 2, OSB / 3, OSB / 4 ) with different properties and you can choose one of these according to the constructional requirements since they have different resistance to moisture and to the loads .
The OSB is often used to realize partition walls or paneling inside workshops and laboratories .
Lately find extensive use in design and furnishing especially for shops that want to express one Industrial style.
The Lamellar Wood is one of the most popular Artificial Woods.
Perhaps because of its characteristic of being virtually multicolored which gives it an elegance and a rhythm uniques.
The lamellar is an artificial wood in half (returning to the football metaphor early we could call “wing”).
In fact it is made up of slats of wood , even precious, glued in a very robust between them.
It’s a very durable wood and particularly suitable for the realization of kitchen’s tops, table tops, shelves etc …
The processing is identical to that of solid wood , but the Lamellar Wood has the advantage of being much more resistant to bending .
I think the aesthetic is wonderful! (purely personal taste)

The Blockboard is sold in panels of various sizes formed from a central core constituted by slats of wood glued together and 2 external panels .
This configuration gives the material a very good strength, but it means a less aesthetic appearance.
To overcome this problem is beaded or laminate with adhesive strips to beautify the edges of which are obvious interior strips .
These slats, which are the structural part of the blockboard wood , are often in hard wood .
The blockboard wood is easy to work with and is used in the production of doors, shelves, racks etc …

The Honeycomb Wood is a panel often used for the realization of doors thanks to its lightness .
And it is precisely its composition to make it so light!
In fact, the Tamburato is formed externally by two skins sheets , which may be of MDF, chipboard or plywood, framed on MDF or chipboard and finished.
Internally, in the area that would have been empty, there is a honeycomb structure which can be made in different materials: paper, polyurethane, polystyrene, aluminum, plastic etc …
Produced in panels of different thicknesses (from 30 to 150 mm) is mainly used to isolate .
Indeed, it is composed in the internal part by an insulating material (polystyrene foam, phenol foam, rock wool, rigid mineral wool or cork), while the outer layers are formed from plywood or particle board .
The sandwich panels are used for vertical panels, ceilings and any situation where there is a need to insulate surfaces.
Obviously the material of which is composed the core of the panel varies depending on the environment in which it will be located and the function.

Laminated Wood is available commercially in the form of different colored panels.
It’s made of chipboard or plywood panels coated with plastic sheets on one or both surfaces.
It is a very robust material and is used mainly for working surfaces and tables, for its uniformity and because you can work and write over it without problems.
Of course you have to edge it. Otherwise the aesthetic would be very unpleasant.
