Of all the materials derived from wood, plywood is undoubtedly one of the best known, but the same thing happens with plywood as with many other boards, which are called the same without distinction and without taking into account the evolution of manufacturing techniques.
The manufacture of plywood consists of “browsing” the trunks of the trees using large machines, in order to obtain thin wooden plates called “laminas”. These sheets are adhered one on top of the other, so that the fibers of one sheet are perpendicular to the fibers of the other. In this way a great material is obtained, perfectly uniform and rigorously calibrated.
The layers of wood are glued in odd numbers. The surrounding layer forms the core of the plywood, current joining processes and the discovery of new glues allow an ideal association of woods.
The woods most used for the production of plywood are: beech, poplar, walnut, ash, birch, mahogany, pine, pumpkin, among other species.
Types of Plywood
The face is made up of selected veneers. The species on the market are very varied, from the cheapest such as pine to the most expensive, which include almost all known noble or semi-precious woods: beech, ash, cherry, oak, mahogany, etc. The back face or counter face of the board is usually made of an appearance of the same species, but of inferior quality, or even of another species. They are malleable, resistant, flexible and their applications are diverse: furniture, kitchens, walls, motorhomes and caravans, etc.
- With three layers
It has the faces connected to a single central sheet. The thicknesses can be identical, or the core thickness can be thicker to improve panel balance. It is normally found in thicknesses of 3 and 4 mm, more rarely in higher thicknesses. Typically used for applications such as drawer bottoms and cabinet backs, trim, jambs, or flashing.
It has the nucleus composed of an odd number of leaves. The thickness of each sheet may be the same as the others, or those with the fibers oriented in the width direction (ie, the “cross”) may be thicker. This serves to give the board the same stiffness in both length and width. Due to its stability and (relative) lightness, this type of plywood is an excellent material for making furniture.
- Cross or drawer
As its name suggests, it is a plywood in which the fibers of all layers are oriented in the same direction. It is a plywood board used almost exclusively for the sides of drawers, or in some other similar applications, where a long narrow piece must support almost exclusively the tensile stress in one direction.
