Wood products are known for their natural beauty, but when selecting a type of wood for your next cabinetry, flooring, furniture or millwork project, it is important to also consider the level of durability by understanding the difference between wood types. Each type and species of wood has an individual cellular structure that creates unique physical properties that determine suitability for different uses.
For example, the hardness of woods varies widely, so certain hardwood species are not recommended for flooring because they are not hard enough to withstand heavy wear and tear.
The following offers a brief comparison of American hardwoods, softwoods and often misused tropical hardwoods and their appropriate applications:
Janka Rating System
When in doubt about the type of wood to select for your cabinetry, flooring, furniture or millwork project, refer to the Janka Rating System, which measures the relative hardness of woods. The hardest commercially available hardwood is hickory, and it is five times harder than aspen, one of the “soft” hardwoods. And while this example lists just some of the most popular hardwood species, there are hundreds of varieties, representing the North American hardwood population. Because hardness is an important factor, and hardness varies for each species, the Janka Scale of Hardness is an excellent tool to help identify appropriate choices.
