Plywood is a wood-slab material known to mankind for centuries. Plywood sheets are composed of several thinner layers of natural wood glued together. The thicker the plywood sheet, the more layers it contains. It is a versatile material with the widest range of applications: from wall and floor coverings to molds for concrete structures, designer furniture and packaging. Nordeco plywood is significantly stronger than some other wood-based sheet materials. Its strength is ensured structurally: the "grain" of each layer is directed differently from the fiber direction of adjacent layers. The alternating fiber direction of each layer is called cross-direction, and can be 90 degrees, which is a right angle. This means that the fibers are directed perpendicularly.
