   Plywood is made by glueing together thin sheets of wood veneer. The thickness of an individual sheet is 0.2 – 3.2 mm. The sheets are composed so that the directions of the grain of the superimposed sheets are usually perpendicular to each other. In normal(birch and poplar) plywood board, there is usually an odd number of sheers (at least three), so the direction of grain of the surface sheets is always the same. In conifer plywood sheets, the number may also be even. In gluing, weather-resistant phenolic resin adhesive is normally used. In terms of colour, it is considerably darker than veneering wood.

In addition, plywood is a staple material for professional builders, architects, designers and DIYers alike. These versatile panels used for many different projects, from wall sheathing, roofing. and sub-flooring, to cabinetry and furniture.

Plywood Size Thickness

       Exterior plywood is going to be strong, but most. it’s designed for water-resistance and weather exposure. Adhesives used in Exterior plywood withstand water. and harsh sunlight for longer without degradation. But, Exterior plywood that will exposed to the elements. engineered wood exterior plywood will still need a surface treatment (e.g. waterproof sealant) . as it designed to covered with siding, flooring, roofing, etc.
