clad plates

What are clad plates or clad plates? We can define this type of board as one that is covered with veneers of natural wood to simulate solid wood.

The idea of ​​veneers is to achieve the appearance, touch and other natural properties of a given wood without all that this may imply: price, overexploitation of species …

Different types of boards can be used as a support for bonding veneers, although the most used are chipboard boards and medium density fiber boards (MDF).

Differences between veneers and plywood

A plywood board is composed entirely of natural wood veneers glued in alternating directions. When we speak of veneers, we refer exclusively to the use of leaves on the external faces.

Therefore, a plywood board can also be a sheet of wood, although not all sheets are, because they are compensated.

In other words, just as we use chipboard or MDF as a support to build a veneer board, we can use plywood.

Features of wood veneer

Many of the characteristics of the veneer, such as the plate’s resistance to moisture, fire, stability, insulating properties or behavior against biological agents will be determined by the plate used as a support.

As we already mentioned, mainly MDF, chipboard and plywood are used. Therefore, it is advisable to consult the technical characteristics of each type depending on the support used.

types of veneers

Some of the characteristics of this type of plate to be evaluated are:

Veneer quality. For stability reasons, the veneered card comes with sheets on both sides, although one, depending on the job, can be completely hidden. In this sense, it is common to sell veneers in which only first quality sheets were used on one side.

For the other side, the one that would be expected to be used for parts that will be partially or totally hidden, plates that may have a greater number of defects (knots, slight variations in tone, etc.) will be used.

Species used for veneers. Each wood will present its characteristics in terms of design and color.

Composition. Different techniques can be used to organize the leaves on the board, obtaining different effects. This is known as joining techniques.

finish. Veneered boards can be purchased naturally, that is, with untreated leaves, or treated. In this sense, there are several possibilities, the most common being: dye, varnish or oil. Veneers can be sanded to renew or apply a new finish. The number of times this can be done is limited, as the thickness of the sheet is also limited.

Singing. One issue to consider when working with this type of board is that it is necessary to trim the edges or edges, for which natural wood veneer is also used. For complex milling, the trim must be used to hide the inside of the panel.

Benefits of using veneered boards

Cost price. Veneered boards in a particular wood are significantly cheaper than a solid wood in question.

Greater aesthetic or compositional possibilities. The use of plates and joining techniques allows different designs or compositions to be obtained.

Demand for certain species is reduced. Much less use is needed «noble wood»For the manufacture of sheet rather than solid board. That is, we can have a piece of furniture that looks zebra And in a way it is, using much less zebrawood than we would use if it were solid wood.

Some technical features have been improved, such as stability. Not all wood is equally stable and some are less stable than the main boards used as a support for the manufacture of veneers, especially if we compare them with plywood.

Main Species

Many species of wood are used to manufacture veneers. Perhaps the most common are: cherry, chestnut, cedar, zebrawood, oak, pine, beech, iroko, ash, ebony, walnut, mahogany, eucalyptus, sapelly or sucupira.

They are not necessarily always used noble species, the price savings with the use of veneers in relation to veneers in solid wood and the greater possibilities of composition offered by veneers justify the demand for veneers of common wood such as pine, beech, etc.

It is amazing that you can even find bamboo leaves.

Sheet Selection

For the manufacture of this type of panels and other products that use natural wood veneers. For this, it is necessary to make a selection or subject them to homogenization processes, in order to offer a product with a certain uniformity. Remember that there may be differences, not large, but obvious, between plates of the same species.

The first classification has to do with the varnish quality, that is, with the amount of defects it can contain. It is worth remembering that those with less defects, better color and more suitable dimensions are classified as superior quality, which is the one that will be used for the visible side of the card.

We can also classify the sheets into depending on your treatment:

  • Natural. She had no treatment.
  • Tinted. The dyes are applied to homogenize the color of the leaf.
  • Pre-composed. In this case, the leaves are not only dyed, but also composed and cut to form a homogeneous product in colors and sizes.

There are other treatments for wood veneers, although these are the most common.

O cut or get the sheet it also plays an important role, especially in the composition of the design.

Finally, we have what is known as joining techniques, which is the way the leaves are laid out on a surface, in this case the plate.

  • In the inverted book. The result is similar to that of an open book. It is also known as a mirror effect. It is the most common technique
  • Without turning. The plates are all placed in the same direction, one after the other. A repetition effect is achieved.
  • Splints. The plates are placed without a defined criterion or at random.
bathed applications

Main Uses

The use of this type of plate is basically limited to decorative interior applications.

  • Coatings for walls and ceilings.
  • Furniture Manufacturing.
  • Interior carpentry: doors …
