Natural & Manufactured Timbers

Timbers are split into three categories: hardwoods, softwoods and manufactured boards.

Hardwoods

Hardwoods

  • Hardwoods are found typically in tropical or sub-tropical climates.
  • Hardwood trees are deciduous trees that drop leaves in winter.
  • Hardwoods mainly have large broad leaves, which usually produce a seed or fruit.
Hardwoods cont.

Hardwoods cont.

  • They have a tighter grain and are expensive.
  • They are generally quite tough and hardwearing.
  • Hardwood trees can take up to 100 years to grow fully.
Softwoods

Softwoods

  • They are found typically in cooler climates.
  • Softwood trees are coniferous trees that usually bear needles and cones.
  • They are frequently called evergreen trees as most keep their needles all year round.
Softwoods cont.

Softwoods cont.

  • They have a looser grain structure and are inexpensive compared to hardwoods.
  • They are generally quite soft, easy to work with and used as construction material.
  • Softwood trees can take up to 25 years to grow fully.
Manufactured boards

Manufactured boards

  • Usually sheets of processed natural timber waste products.
  • Made from waste wood, low-grade timber and recycled timber.
  • Often covered with thin slices of a more expensive wood called a veneer.
Manufactured boards cont.

Manufactured boards cont.

  • They have a pale brown appearance with no grain.
  • They are generally quite lightweight, easy to work with and used as construction material.
  • Often made up of several layers mixed with adhesive to increase their strength.
