Hardwood or Softwood Doors and Windows?

There are basically two main types of timber – softwood or hardwood.

The terms softwood and hardwood can be a bit misleading since some softwoods are hard and some hardwoods are soft. Balsa wood is a deciduous angiosperm and is classified as hardwood even though the wood itself is quite soft! The most important thing to keep in mind is both of these kinds of woods have unique properties that are suited to a home’s different needs. The differences between softwoods and hardwoods are based on their cellular structure.

The softwood and hardwood terminology does make sense. After all, evergreens have a tendency to be less dense compared to a deciduous tree which makes it easier to cut. On the other hand, most hardwoods are more difficult to cut because they are so dense. So as the balsa wood classification shows, there are no minimum weight requirements for being a hardwood.
