Plywood is a building material that is used in everything from furniture to house construction. It is a versatile and highly workable building material because the layering of thin sheets of wood gives it great strength and flexibility. The properties of plywood include increased stability, high strength, flexibility, fire resistance, etc.

The following are the properties of the plywood:
01. Increased Stability:
Plywood offers all the advantages of the parent wood plus has additional strength and stability because of its laminated structure.
02. High Impact Resistance:
Plywood has high tensile strength, derived from the cross lamination of panels. This distributes force over a larger area and reduces tensile stress. Therefore able to withstand overloading by up to twice its designated load. This is useful where the seismic activity or cyclonic winds occur. These plywood properties are effective when used as a flooring or concrete formwork.
03. High Strength:
Plywood combines the structural strength of the timber from which it is manufactured. This is in addition to the plywood properties obtained from its laminated design. Cross-graining allows the plywood sheets to resist splitting and provides uniform plywood strength for increased stability. It is cost effective when used in structural applications such as flooring, formwork, shear walls, etc.

04. Panel Shear:
Due to its cross laminated structure; plywood has a panel sheer nearly twice that of the solid wood. Therefore it is the highly effective material used in gussets portal frames, as bracing panels and webs of fabricated beams.
05. Chemical Resistance:
Plywood does not corrode and therefore can be used in chemical works and cooling towers as a cost effective, durable material.
Plywood can be manufactured to fit every requirement. The veneer thickness varies from a few millimeters to inches. The number of veneers used also ranges from three to several, increasing the thickness of the sheet. The extra layers add more plywood strength. Thin veneers are used to increase flexibility for use in ceilings and paneling.

07. Fire Resistance:
Plywood can be treated with a fire resistant chemical coating. It is combined with non-combustible materials such as fibrous cement or plasterboard. This makes it ideal for use in fire resistant structures.
Plywood has high thermal and sound insulation. Insulation plywood can greatly reduce heating and cooling costs. This makes it useful insulating material for ceilings, flooring, roofing, and wall cladding.
The unique properties of plywood, its cost effectiveness, and ease of use will continue the plywood become popular building material.
