Plywood siding materials are widely used in modern construction-business. They are popular because of their light weight and their relative cheapness. The cost of the material per unit area of wall is usually less than for other siding materials. Besides, labor costs are also relatively low. The reason for it is the fact that large sheets of plywood are more quickly installed than the boards of the same area. In many cases, if it is necessary, the sheathing can be eliminated from the building if plywood is used for siding. This operation, if it is performed, leads to further cost saving.
It should be taken into account that usually plywood sidings must be painted in order to save them for decay. But if they are produced from decay-resistant material, they can be left to weather effects without the surface coverage.
