Wood is split into two kinds, soft wood and hardwood. A tree has a ring for every year it grows, the darker part of the ring is strong. Softwoods have big growth gaps between the rings making them softer. Hardwoods have closely packed rings because they grow slower. This makes them hard.

Softwoods grow much quicker which makes them cheaper to produce and quicker to replace. They are trees which have needles and cones and don’t lose hem in autumn (evergreen) such as pine trees. Hardwoods are much more expensive and the trees are deciduous (lose their leaves in autumn).

- Larch: A darker honey colour, resident to rot, perfect for decking and outdoor furniture.

- Spruce: Darker red in colour, it’s quite knotty and rough. Used for packing boxes, sheds and masts.

- Beech: Lighter brown coloured. It’s dense but when cut thinly can be bent without splitting. Often stem bent to make curved furniture.

To save money, use wood by-products (like sawdust) or produce board for a specific need manufactured boards have been developed.

- Ash: Pale coloured, absorbs shock well so often used for tool handles and sports bats. Polishes well to make furniture.

Chipboard:

Chips or shavings of wood are compressed together with glue to form board.

It is generally covered in a smooth veneer top (like kitchen worktop).

It’s very cheap to produce and not very strong.

Often used in cheap flat pack furniture.

Layers of hard and softwood are glued together at right angles (to improve strength).

Cheap to produce.

The layers make it stronger than some solid woods.

Used for building and furniture.

Blocks of wood are glued together to form a sheet.

Can be quite strong, especially if it is veneered to give a polished surface.

More resistant to moisture than other manufactured board.

Used for work tops as it can resist moisture and stay flat (it doesn’t warp).

Medium Density Fibreboard (MDF):

Tiny fibres for wood are packed together with glue and set into sheets.

It has a smooth finish so can be cut and painted.

It is not suitable for outdoor use as it absorbs water.

Perfect for cheap painted furniture and shelving.
