Engineered Wood

Engineered wood is also called as composite wood, manmade wood or manufactured wood. These products are manufactured by binding strands, particles, fibre’s or veneers of wood together with a strong adhesive. These include plywood, hardboard, particle board, veneer sheet, oriented strand boards, Glulam, etc. These products are manufactured to make wood more easily to use for commercial purposes; be it construction, home appliances or even industrial purposes.

ADHESIVES USED FOR MAKING ENGINEERED WOOD

  • Urea-formaldehyde resins (UF): most common, cheapest, and not waterproof.
  • Phenol-formaldehyde resins (PF): yellow/brown, and commonly used for exterior exposure products.
  • Melamine-formaldehyde resin (MF): white, heat and water resistant, and often used in exposed surfaces in more costly designs.
  • Methylene diphenyldiisocyanate (MDI) or polyurethane (PU) resins: expensive, generally waterproof, and does not contain formaldehyde.

Below are some common engineered products:

 

Hardboards:

A thin manufactured board made from compressed wooden particles - one side smooth and the other side rough. These boards are denser than medium density hard board but harder and have great strength. They are processed in wet and dry methods. While wet method leaves one side rough and one side smooth. The dry process leaves both sides smooth. Hardboard has more strength than particle board. It does not crack or split easily.

Hard boards are used for construction of houses in specific for construction of divider walls, beds, cabinet panels, etc. They are also commonly used in automobiles to make decks on windows, panel doors, dash boards, etc. Hard Board is used commonly in many industries as they are very economically priced.


  • CHARECTERISTICS: Strong, stiff and durable. One side is normally smooth and other side rough.

  • USAGE:Furniture, construction, automobiles,cabinets, home appliances, acrylic use, handicrafts,etc.
