Types
Chipboard
Chipboard is a man-made sheet material, made from small chips of timber glued together to produce a dense sheet.
Disadvantages- Not strong, not suitable for damp conditions as it absorbs water causing it to expand,
Advantages- cheap, covered in veneer to improve aesthetics and durability

Hardboard
They are similar to MDF. They come in thin sheets and have a dark colour. It is very dense. They are used in tools rack, panel wall lining and back of picture frames
-
Block board
It is made from strips of timber that are glued together, with veneers normally glued top and bottom to hide the surface strips. They have high-bending and bowing resistance. They are used in work tops and shelving.
-
Plywood
Plywood consist of layers of veneers glued together using formaldehyde resin. The odd number of veneers are used to stop warping. Veneers are glued at right angles, making plywood strong.

Laser plywood- They can easily be cut using lasers. They have no gaps in between layers making it high quality. it also uses glue that is non-toxic, However they are less dense than regular plywood.
Birch plywood- Pale colored plywood, which is hard and heavy. This means it is more expensive. They have little splintering
