Wooden Construction Materials

The veneer are the thin slices of the wood which are less than 3 mm thin and they

are stuck on to the core panels of particle boards, wood or fibre boards in order to make flat panels like tops, cabinet panels, door, furniture parts or even parquet floors. This veneer is made by peeling the tree trunk or by slicing down the large bocks of woods called flitches. The veneer beading is the layer of wafer thin decorative edging which is used for putting around objects like jewellery boxes for giving them a decorative look. The figures and the grains on the wood are related to the growth rings in the tree and it also depends on the angle from which the wood has been cut. The process of veneering dates back to history, the Egyptians made use of veneers for making their furniture long ago and the veneers used to be sawn, but that lead to a lot of wastage of wood, so the process was done away with.

The plywood refers to a type of timber which has been manufactured out of the thin sheets of wood veneer, they consist of at least three or more than three layers of veneers which are stuck to each other to provide strength to the material. The plywood is one of the most used wood products since it is cheap, workable, flexible, can be locally manufactured and is easily reusable. The plywood is better than normal wood since the plywood had a resistance to shrinking, warping, twisting, and cracking and it also has a very high degree of strength. Initially this happened when the Egyptians used this method when they faced a shortage of wood of good quality, so they used to stick the thing layers of good wood over the low quality woods.

There are several varieties of plywood which are used for different purposes, they are hardwood plywood, softwood plywood, tropical plywood, aircraft plywood, decorative plywood, special purpose plywood, marine plywood, flexible plywood, pressure treated plywood, moisture resistant plywood, sign grade plywood and fire retardant plywood. A particle board is a composite material; it is an engineered wood product which is made out of wood particles like sawmill shavings, saw dust, wood chips. These wood particles are mixed with a suitable binder like resin and then extruded and pressed to make a particle board.
