popular, but its use is often limited by cost. - Therefore manufactures can create a range of
laminates, composites and other man-made boards - chip board - block board - MDF - hardboard

- There are two types of wood
- Hardwoods
- Softwoods
- Hard woods are deciduous, while softwoods are
generally coniferous (often called evergreen).
The size of the tree determines the size of the
timber. All woods are seasoned
