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:

 

Fibre Board:

Fibre board is a wood product sold in large thin sheets. It is similar to that of ply wood but offers higher density and strength. It is commonly made from softwoods like pine, but it also includes wood scraps, saw dust, cardboard, paper, etc. These shredded materials of wood and workable material are placed inside equipment known as defiberator, which turns the wood scraps into fine fibres. These fibres are mixed with wax and resin and pressed into sheets to make fibreboards.
Fibreboard is available in 3 types- low density, medium density and high density boards. Medium density fibreboards are widely used.


  • CHARECTERISTICS: Strong and durable. However, it is not resistant to moisture and humidity.

  • USAGE:Furniture, cabinets, home appliances, etc. Mostly for indoor use.
