TYPES OF WOOD:-
Before we get into all of the different wood varieties and their common uses, it’s important to understand the three basic types of wood you might encounter. These three types are: softwoods, hardwoods, and engineered wood. Each of these different wood types can be used in a number of different ways.
Solid wood is a term most commonly used to distinguish between ordinary lumber and engineering wood , but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers , or veneers with adhesives to form a composite material . Engineered wood includes plywood , oriented stand board (OSB) and fiber board. The fact that a product is made from solid wood is often touted in advertisements. However, using solid wood has advantages and disadvantages.
COMPARISON WITH ENGINEERED WOOD:-
Perhaps the greatest advantage of solid wood is that the wood is the same all the way through, so repairs are relatively easy. Repairs to veneer are much more difficult and sometimes impossible.
Solid wood furniture is strong enough to easily satisfy all furniture applications, and it can last for centuries. Society is still questioning whether furniture made of plywood (often made from pine) can do the same. Plywood and other engineered wood products used to make furniture are typically covered with a veneer such as Cherry.
It is common today for furniture manufacturers and retailers to advertise such veneered plywood furniture as made of “wood solids with cherry veneers”. Most customers believe that to mean solid planks of less expensive woods such as poplar, etc., with expensive woods such as cherry used for veneers. However, “wood solids” is a term of art. The “wood solids” are simply plywood, or another engineered wood product.
In the USA, the Federal Trade Commission doesn’t allow furniture to be advertised as made of “solid wood” unless all exposed surfaces are in fact solid wood. Solid wood is expensive. Engineered wood (often advertised as wood solids) is not.
