Are man-made and often use unwanted products of woods. Sections of timber, thin veneers or wood particles glued together and compressed.


  • Come in wide boards, wider than timber.
  • Can cover large areas at a cheap cost.
  • In plywood, alternating grains at 90degrees increases strength.
  • A lot cheaper than natural timber.
  • Veneers can be used to cover unplesent surfaces.


  • Screws and nails find it hard to stay attatched.
  • Edges and surfaces can be unplesant.
  • Some split easily and absorb water and are hard to seal and finish.
