lastulevyt
Lastulevyt, or plywood, are engineered wood panels made from thin sheets of wood veneer stacked with alternating grain directions and bonded under heat and pressure. The veneers are typically birch, pine, spruce, or other fast-growing species, depending on regional supply and intended use. Adhesives such as phenol-formaldehyde, urea-formaldehyde, or melamine resins glue the layers, with exterior- or marine-grade glues used for moisture-resistant varieties.
Because the grain alternates, plywood has improved strength, rigidity, and dimensional stability compared with solid wood
Sizes and thicknesses vary by market. In North America, sheets are typically 4 by 8 feet (about
