• Engineered wood, man-made wood, or manufactured board; includes a range of derivative wood products which are manufactured by binding or xing the strands, particles, bres, or veneers or boards of wood, together with adhesives, or other methods of xation to form composite materials.
• With reconstituted wood materials, changes in properties are studied at the bre, particle, ake, or veneer level. roperties of such materials can be changed b! combining, reorgani"ing, or stratif!ing these elements.
 
•  #hree general categories$ plywood, particle and ber composites, and wood–non wood composites.
•  #he third categor!, wood%non&wood composites, includes products made from combining wood bers with agricultural bers, with thermoplastics, and with inorganic materials.
• 'onventional wood composite materials fall into ve main categories based on the ph!sical conguration of the wood used to make the products$ plywood, oriented strand board, particleboard, hardboard, and cellulosic ber board.
• 'an be tailored to the end&use application of the product.
• (ar!ing the physical conguration of the wood.
• Ad)usting the density of the composites.

• Wood particle geometr! is important % t!picall!, the anatomical longitudinal direction should parallel the long axis of the particle.
• arallel alignment of particles gives strength properties more similar to solid wood
• igher in longitudinal direction.
• 1ore adhesive & higher strength properties and water resistance

• l!wood is a at panel built up of sheets of veneer called plies, united under pressure b! a bonding agent to create a panel with an adhesive bond between plies.
•  #he properties of pl!wood depend on the 8ualit! of the di9erent la!ers of veneer, order of la!er placement, adhesive used, and control of bonding conditions.
• 4t is alwa!s constructed with an odd number of la!ers with the grain direction of ad)acent la!ers oriented perpendicular to one another.
• Since la!ers can consist of a single pl! or of two or more plies laminated such that their grain is parallel, a panel can contain an odd or even number of plies but alwa!s an odd number of la!ers.
•  #he outside plies are called faces or face and back plies; the inner
plies are called cores or centres; and the plies with grain

•  #he core ma! be veneer, lumber, or particleboard, with the total panel thickness t!picall! not less than C.B mm C:CB in.- or more than B mm in.-.
• l!wood can be glued, screwed, cut and sawed, and fasteners can be used too, much like solid wood.

• ?reater resistance to splitting
• igh strength&to&weight and strength&
to&thickness ratios, and its sti9ness
and strength are more e8ual in width and length than are sti9ness and
strength of solid wood
• 3xcellent dimensional stabilit! along its length and across its width.
•   1inimal edge&swelling makes pl!wood perhaps the best choice for
adhesive&bonded tongue&and groove
 )oints, even where some wetting is expected.
'isadvantages • Si"e$l!wood is available Eo9 the shelfE almost
exclusivel! in unwield! >&foot&b!&@&foot sheets. l!wood cannot be made thinner b! surfacing, as can be done with lumber. Attempting to do so will severel! damage the pl!wood.
• 'an be custom&ordered in the same si"e and shape as other lumber if desired, but the expense is prohibitive.
• 1ore susceptible to moisture and weather damage than regular lumber.
• 'apillar! action, draw the water deep into the wood. #his compromises the integrit! of both the wood and the adhesive used to hold the la!ers together.

• *S0 is eas! to saw, drill, nail, plane, le or sand. 4t contains wood, full! cured waterproof and boil proof resin adhesive and a small amount of wax.
• 6ormal carpentr! tools can be used, but carbide tipped blades are recommended for prolonged use.
6A4+A04+4#2
•  #he man! interleaved la!ers create panels with good nail holding properties. 6ails can be driven as close as C:>E from the panel edges without risk of splitting or breaking out. owever, an edge distance of :@E for structural applications is recommended.

Advantages
• Available in large si6es. *S0 can be manufactured into larger panels than pl!wood and o9er more cost saving options for toda!Ks builders
• Consistent7 anels are dense and solid throughout the product. *S0 panels do not have core voides like pl!wood panels do
• 8ood shear strength7 
• 9esource-e:cient7*S0 panels are considered greener b! some as the! are manufactured from smaller, sustainabl!& grown trees rather than old&growth forests
• A;ordable7 
'isadvanages
• <eavy7 *S0Ks relative densit! could be seen as a bad thing. a <:< pl!wood panel weighs <.< pounds per s8uare foot compared to <.> pounds for an *S0 panel of the same thickness.
• Lower moisture tolerance7 When pl!wood is exposed to moisture it swells evenl! throughout the panel and returns to its nominal thickness as the wood dries.
• *rone to swelling edges and telegraphing7
 
 
A5#4'+3 0*A57 • 6eed to dispose of large 8uantities of sawdust, planer shavings, and
to a lesser extent, the use of mill residues and other relativel! homogeneous waste materials produced b! other wood industries.
• Simpl! put, particleboard is produced b! mechanicall! reducing the material into small particles, appl!ing adhesive to the particles, and consolidating a loose mat of the particles with heat and pressure into a panel product.
• articleboard is t!picall! made in three la!ers. #he faces of the board consists of ne wood particles, and the core is made of the coarser material.
• owever, particleboard is generall! not as strong as breboard because the brous nature of lignocelluloses is not exploited as well.

particle board holds the screws in place under similar weight.
'!A'>A%#A8E •  #hough it is denser than conventional
wood, it is the lightest and weakest t!pe of breboard, except for insulation board.
• A ma)or disadvantage of particleboard is that it is ver! prone to expansion and
discoloration due to moisture, particularl! when it is not covered with paint or another
sealer.
•  #herefore, it is rarel! used outdoors or in places where there are high levels of moisture, with the exception of some

• Acclimati"e and inspect tiles and wall ceiling surface. • 5emove tiles from packaging. Spread out in room for at
least < hours prior to installation. • repare the cork tiles and wall:ceiling surface for

tiles to substrate. • Spread contact cement over the entire back of the cork
tiles and allow it to full! dr!.
 
7isadvantages$ • 'ork is prone to damage and indentation
caused due to heav! ob)ects. • 'leaning of cork oors is cumbersome. 4t
does not allow for wet mopping. Water absorption can damage cork, making it important that spills are cleaned up 8uickl!.
• 7iscoloration of cork oors can occur when exposed to direct sunlight over long periods of time or due to age.
•  #he cost of cork is more than installing most of the tiles or carpets.
  Advantages • 'ork is one of the most renewable wood products for a
oor covering. #hese trees are protected. *nl! about two&thirds of the bark is removed from the tree and it has enough bark left to make a natural defence and to ensure a long life.
• 'ork ooring possesses a spring&like nature and hence has an inbuilt resistance to minor indentations. 0ecause it is incredibl! dense and has a uni8ue cellular structure that is impregnated with about =FO of air.
