Manufactured Boards

Manufactured boards are timber sheets which are produced by gluing wood layers or wood fibres together. Manufactured boards often made use of waste wood materials. Manufactured boards have been developed mainly for industrial production as they can be made in very large sheets of consistent quality. Boards are available in many thicknesses.

Plywood

Blockboard

Manufactured Board properties:

• Manufactured boards often made use of waste wood materials.
• Saw dust is used to make MDF and hardboard.
• The saw dust is held together with glue.
• Boards are inexpensive so are often used as instead of real woods.
• Manufactured boards do however do not look as good as real woods look.
• Manufactured boards are often covered with a thin layer of real wood which
is called veneer this improves their appearance.
